| The command without parameters writes out the status of monitoring or storing of auditing information (see also Object Group - monitoring changes in configuration). Parameter REINIT USERS causes the writing of the current configuration of all objects of *User* type into the monitoring database. Parameter REINIT RES_GROUP causes the writing of the current configuration of necessary objects of *Object group* type into the monitoring database. In any object type is not stated in the command, both types of objects will be written into the monitoring database. | ||||||||||||||||||||||||||||||||||||
BACKUP SYSCFG path | Creates a configuration database backup in a directory specified by the path parameter (Sybase SQL Anywhere and PostgreSQL platforms). Note: The backup can be influenced by the setting of ConfigBackUpTimeout parameter. | ||||||||||||||||||||||||||||||||||||
BACKUP LOGFILE path | Creates a log database backup in the directory specified by the path parameter (Sybase SQL Anywhere and PostgreSQL platforms). | ||||||||||||||||||||||||||||||||||||
CFGSYNCHROAUTO ON/OFF | Enables/disables the automatic synchronization of configuration databases after a new SBS (standby server) is connected. Note 1: The command can be applied to the HOT server only. Note 2: The synchronization can be influenced by the setting of the parameter ConfigSynchroTimeout. | ||||||||||||||||||||||||||||||||||||
CHECK_ARCHIVE | Checks a value type consistency between the primary archive object and the archive one and shows the errors (writes it into the log). The error is if the value type of the primary archive object is different from the value type of historical value. | ||||||||||||||||||||||||||||||||||||
| If some files - the external and user libraries for Java, placed in directory %lt;appldirgt;/java/shared are changed, the D2000 Server will send these files to all running clients. | ||||||||||||||||||||||||||||||||||||
DI ON/OFF DI /E+dbginfo DI /E-dbginfo | Debug Info - shows (DI ON)/ hides (DI OFF) internal debug information of D2000 Server (in the process window and in the process D2000 Sysconsole). The command allows show/hide viewing debug information by category as the SysConsole user interface allows. Example 1: Show debug information DI /E+DBG.CFG_RQ Example 2: Hide debug information DI /E-DBG.CFG_RQ | ||||||||||||||||||||||||||||||||||||
DP ON/OFF | Debug Pipe - enables/disables the displaying of the communication of the D2000 Server with client processes (only if the D2000 Server's window is displayed on the desktop). | ||||||||||||||||||||||||||||||||||||
ENABLEAUTOSTARTPROCESSES | Since version v23.0 If the kernel was started with the /N parameter, i.e. so that it does not start processes, by calling this tell command, startup is turned on and kernel processes start. | ||||||||||||||||||||||||||||||||||||
| It is used to determine and set the active instance, preferred instance, and instance mode in a load-balancing mode.
| ||||||||||||||||||||||||||||||||||||
MESSAGE Message_Text process_name | Broadcasts (sends) a text message to client processes. The process name can be entered as a mask (e.g. *.HIP - for all processes D2000 HI). If the return code is Success, it contains the number of clients, and the message from the D2000 Server was sent. | ||||||||||||||||||||||||||||||||||||
LIC_PostponeLicWrnToUsers 0 až 240 [hod], default 24 | Delay of license warnings for common users. The administrators of D2000 will get the license warning always and immediately. | ||||||||||||||||||||||||||||||||||||
LIC_DoNotAllowConsoleOverLimit 0|1, default 0 | When setting 1, the system will not allow connecting consoles (HI) over the scope of the license. | ||||||||||||||||||||||||||||||||||||
LIC_DoNotAllowSysProcOverLimit 0|1, default 0 | When setting 1, the system will not allow the system processes (CALC, EVENT, KOM,...) over the scope of the license. | ||||||||||||||||||||||||||||||||||||
RD_SET_HOT serverName | Sets the HOT server in the redundant system. The parameter serverName is the name of the server within the redundant group. | ||||||||||||||||||||||||||||||||||||
| On-line refresh of the information about the license range (from file LicenceRun.code or LicenceDev.code) and information about the network clients (from file ConsolesInfo.txt). It enables changing the license range without any need to stop the system - as well as re-reading the list of network clients after it has been manually edited. Note 1: In redundant systems, it is necessary to replace the files LicenceRun.code or LicenceDev.code on all redundant servers. Note 2: In redundant systems, it is necessary to modify the file ConsolesInfo.txt only on the active (HOT) server. The changes will be transferred to all SBS servers. Note 3: The information about the license is sent to the client processes when connecting to D2000 Server. For that reason, if the change of license affects even other processes than D2000 Server, they must be restarted. For example, when a user adds a new communication protocol, it influences the D2000 CNF process. To enable this protocol in D2000 CNF, it must be restarted. Also, when adding a new communication station and I/O tags with the given protocol to the D2000 KOM process, it must be restarted. | ||||||||||||||||||||||||||||||||||||
RELOAD_PARAMS | Reloads all parameters for D2000 Server (except the parameters for saving the monitoring database to the depository) from the registry (Windows) or from the configuration file (Linux) without restarting the D2000 system. | ||||||||||||||||||||||||||||||||||||
RELOAD_SECURITY | Sets the new configuration of Security Policy without restarting the D2000 System. | ||||||||||||||||||||||||||||||||||||
REPAIR_ARCHIVE | Checks the consistency of value type between the object being archived and the historical value. If some error occurs, it will be repaired immediately and information will be written into the log. The error is if the value type of the object being archived is different from the value type of historical value. | ||||||||||||||||||||||||||||||||||||
| Initialize the path to the repository. If the directory does not exist, a new one will be created. If there is a repository on a given path, this one will be used for storing object history. History capturing must be disabled. | ||||||||||||||||||||||||||||||||||||
REPOSITORY DISCONNECT | Remove the setup path to the repository. History capturing must be disabled. | ||||||||||||||||||||||||||||||||||||
REPOSITORY ON|OFF | Enable/disable history capturing. A path to the repository must be set. | ||||||||||||||||||||||||||||||||||||
RESTART process_name | Stops the given process and then starts it correctly. Note: If the process is stopped (Stop or Crash status), the command just starts it. | ||||||||||||||||||||||||||||||||||||
process_name mode | Activates/deactivates Load balancing mode for D2000 Archiv (see the chapter Redundant archiving - Load balancing) or D2000 Kom processes (see the chapter Redundancy of communication process KOM) processes. Example: SET_LOAD_BAL_MODE SELF.ARC 1 - activates Load balancing mode for SELF.ARC process. SET_LOAD_BAL_MODE SELF.KOM 1 - activates Load balancing mode for SELF.KOM process. | ||||||||||||||||||||||||||||||||||||
| The command writes the list of the names registered by the GETACCESS action within the application (with the keyword PUBLIC) into the text console and to the log file (kernel.log) of the D2000 Server process. Example: | ||||||||||||||||||||||||||||||||||||
SHOW_ARC_STAT process_name | Shows the statistical information about the running instances of the archive - the maximum number and sum of the read requests that are being processed. | ||||||||||||||||||||||||||||||||||||
| Shows configuration information of the process D2000 Server. This information covers:
| ||||||||||||||||||||||||||||||||||||
| Shows dynamic information on the specified object (list of objects that dynamically or statically use the object) on the text console of the D2000 Server process. | ||||||||||||||||||||||||||||||||||||
SHOW_DYNO_LIST idFirst idLast | The command dumps the list of current dynamic objects (ID and object name) to the text console of the process based on the defined interval. Note: The command is mainly intended for diagnostic purposes. | ||||||||||||||||||||||||||||||||||||
SHOW_TRANS_LIST | Lists internal transactions of the D2000 system. Note: The command is intended to be used mainly for the D2000 System diagnostic purposes. | ||||||||||||||||||||||||||||||||||||
SHUTDOWN D2000 | Stops the D2000 system. | ||||||||||||||||||||||||||||||||||||
SHUTDOWN RESTART_D2000 | Restarts the D2000 system. | ||||||||||||||||||||||||||||||||||||
SHUTDOWN RESTART | Stops the D2000 system and restarts the operating system. | ||||||||||||||||||||||||||||||||||||
SHUTDOWN SHUTDOWN | Stop the D2000 system and shutdowns the operating system. | ||||||||||||||||||||||||||||||||||||
SHUTDOWN WINNT | Stops D2000 System and restarts the operating system. | ||||||||||||||||||||||||||||||||||||
START process_name | Starts the specified process. | ||||||||||||||||||||||||||||||||||||
STDOUT output | The command redirects the standard output to a new output specified by output. Example: | ||||||||||||||||||||||||||||||||||||
STOP process_name [FORCE] | It stops a process. When using the optional parameter FORCE, the termination of the process will be forced. | ||||||||||||||||||||||||||||||||||||
*SUSPEND* SLEEP [WAKEUP yyyy-mm-ddThh:mi:ssZ]|HIBERNATE | It causes the operating system to switch into sleep mode (SLEEP) or hibernation (HIBERNATE). If the OS switches into sleep mode, the user may define a time of its automatic awakening by the parameter WAKEUP yyyy-mm-ddThh:mi:ssZ, where yyyy-mm-ddThh:mi:ssZ defines UTC time of awakening. The string must be in ISO 8601 format (http://sk.wikipedia.org/wiki/ISO_8601). Example: *SUSPEND SLEEP WAKEUP 2015-02-11T12:00Z* - causes putting the computer to sleep and automatic awakening at noon, February 11th, 2015 (UTC). | ||||||||||||||||||||||||||||||||||||
| It enables, disables, or queries the delay of data transfer between the D2000 Server process and the client connected via TCP/IP protocol. Setting the parameter TCP_NO_DELAY to TRUE disables TCP delay before sending TCP packets (setsockopt function with parameter TCP_NODELAY - see Nagle's algorithm). The delay improves the efficiency of TCP/IP networks by reducing the number of packets that need to be sent over the network. On the other hand, if the communicating partners wait for each other's response (e.g. remote procedure calls between two EVENT processes or between HI and EVENT), this delay can significantly slow down the execution of scripts and other interactions. By default, TCP delay is on (TCP_NO_DELAY = FALSE). This TELL command is intended only for tuning and debugging purposes. Note 1: When registering a TCP/IP client, the process D2000 Server queries the value of parameter TCP_NO_DELAY, and, depending on this value, it does or does not change the parameter TCP_NO_DELAY for client connection. This value is then sent to the client, which also changes the TCP_NODELAY parameter of its TCP connection to the server. Warning: In the current implementation, the TCP_NO_DELAY command does not cause any change in the setting on the client's side! Note 2: Besides the TCP_NO_DELAY parameter, there is also another parameter that influences sending TCP delayed acknowledgements (it can be set on OpenVMS and *nix system by calling sysconfig -r inet tcpnodelack). This parameter induces a 200 ms delay before sending TCP acknowledgements and it can interact with the TCP_NODELAY parameter. | ||||||||||||||||||||||||||||||||||||
XML file(s) export from the directory, which is defined by the parameter path, together with the following parameters:
_TABLE | The configuration parts exported to the XML The path for the file export on VMS must be written in Unix format. Correct syntax: /DKB0/d2000/d2000-app/RIS_ROVE/XML/ mask Incorrect syntax: DKB0:[d2000.d2000-app.RIS_ROVE.XML] mask - this syntax is not supported, export ends with an error. Kotva | | xml_export_table | xml_export_table | XML_EXPORT_TABLE The configuration parts exported to the XML files, which is not part of the object configuration.|||||||||||||||||||||||||||||||||
| Warning: This command is not supported for OpenVMS. XML file(s) import of a specific file or of all XML files from specified directory, depending on path_to_dir / path_to_file parameter: path_to_dir - directory name with XML files (eg D:\temp). Note - the directory is searched for xml files recursively. path_to_file - absolute path to the XML file (eg D:\temp\H.Sec.xml) For this TELL command to be executed, a configuration key must be present!. The path for the file import on VMS should be entered in Unix format. Note: The command belongs to the "security" TELL commands. I.e., it can be activated only from interactive processes with configuration key or from process D2000 Event Handler. | ||||||||||||||||||||||||||||||||||||
| Import of the configuration parts that are not part of the object configuration from XML files. The parameter [Path, FileName, TableName[, CleanTable]]
The initialization of the TELL command is conditioned by using the configuration key. Note: The command belongs to the "security" TELL commands. I.e., it can be activated only from interactive processes with configuration key or from process D2000 Event Handler. Kotva | | xml_settings | xml_settings | XML_SETTINGSWarning: Since the version V8.00.001, the command is not supported.|||||||||||||||||||||||||||||||||
| Partial update of the objects by XML from the directory, which is defined by parameter Path. The parameter: [path_to_dir / path_to_file] Note: The command belongs to the "security" TELL commands. I.e., it can be activated only from interactive processes with configuration key or from process D2000 Event Handler. |
...
BACKUP [path] | Creates an archive database backup. If the parameter path is not specified, the backup will be performed into the directory, which is set in the archive configuration. Note: this command is supported for Sybase SQL Anywhere only. To back up Oracle/PostgreSQL/MsSql databases, use their respective utilities. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Executes recalcs of old values, which were redirected to the auxiliary calc task (see the RecalcImmediateDepth archive parameter), and then instead of being performed, they were stored to the file (see the DropOldRequests archive parameter). If path+filename is not specified, the file name_ARCHIV_DROPPED_CALCS.DAT will be processed by name.ARC and then renamed to name_ARCHIV_DROPPED_CALCS.DONE (if such a file exists, it will be deleted). Note: This command fails if the archive parameter DropOldRequests has value 1 because in this case the recalcs would be again stored to the file after being read. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| A command that must be run after the change of DataTableSlices parameter from value 1 to value 2 (i.e. after changing the time slices mode to time slices for structured archives only). The archive will transfer the archived values from time slices of simple archives to the original data tables and these time slices will be deleted. Note: for simple archives, from the start of the archive till the transfer of archived values to the original data tables, the archive will provide only data which are located in original data tables. Therefore this conversion is recommended only for systems with redundant archives and the archive performing conversion should be set as a passive instance. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
CRC path\filename mask from to [step] [PO] | Parameter checks the identity of data in instance archives. Creating the file with a CRC (checking sum) for archive objects that correspond to the mask for the entered time period. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
CRC_TREE path\filename name row col from to [step] | Parameter checks the identity of data in instance archives. Creating the file with CRC (checking sum) for archive objects that correspond to the mask for the entered time period. The calculation will be realized for the object that has been defined by parameter "name row col" and for all objects that influence its value. The optional parameter step (in hours) allows dividing the calculation for the time period into intervals. See the note to the CRC command. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
DEL mask [before] | Deletes data from the archive database as follows:
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Deletes data from the archive database without activation of dependent statistics evaluation (similar to the action DELETEARCHDATA). Time format is dd-mm-rrrr hh:mi:ss.mss. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
DI ON/OFF | Debug Info - shows/hides internal debug information of the D2000 Archiv process (in the process window and in the D2000 Sysconsole process). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Debug Info for values - enables/disables displaying information about the evaluation of historical values with specified HOBJ or with the name matching the given mask. For structured historical values, you can specify the required structure item - column (if ROW=0) or row (if COL=0). Example: | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
DI ONREC/OFFREC HOBJ/mask [ROW [COL]] | Debug Info for values - recursive. The command extends the functionality of the previous commands with the possibility of showing / hiding the debug information for historical values that depend on specified historical values (e.g. minute averages). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Sybase platform: The parameter path+trezor_name specifies the path and the name of the depository database to dismount. The * and ? characters for mask definition can be used in the depository database name. If more files match to entered mask, all these ones will be dismounted. For more information see the topic On-line access to data from depository databases. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
DISMOUNT_TREZOR trezor_name [SEGMENT seg] DISMOUNT_TREZOR IdFrom IdTo [SEGMENT seg] | Oracle platform: The parameter Id or trezor_name defines the number (name) of the depository database to dismount. The name of the depository database is the name of the depository tablespace (e.g. MYAPP_TS_TREZOR15 or MYAPP_TS_TREZOR15_02) or the name of the tablespace's datafile (e.g. MYAPP_TS_TREZOR0015_S02_20040801.ORA). You can also dismount all depository databases (except the ones that are currently being filled) by using the parameter all. The parameters IdFrom and IdTo allow dismounting a sequence of depository databases. The parameter SEGMENT seg (where seg is the number of depository database segment) allows dismounting just the segment. Seg is the number between 0 and TrezorCountSegments. If the DISMOUNT_TREZOR command is used without the SEGMENT Seg parameter for depository database with segments enabled, the process D2000 Archiv attempts to dismount all segments of specified depository database/s. For more information see the topic On-line access to data from depository databases. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
DISMOUNT_TREZOR IdFrom IdTo [SEGMENT seg] | PostgreSQL platform: The parameter Id defines the number of depository databases to dismount. You can also dismount all depository databases (except the ones that are currently being filled) by using the parameter all. The parameters IdFrom and IdTo allow dismounting a sequence of depository databases. The parameter SEGMENT seg (where seg is the number of depository database segment) allows dismounting just the segment. Seg is the number between 0 and TrezorCountSegments. If the command DISMOUNT_TREZOR is used without the parameter SEGMENT Seg for depository database segments enabled, the process D2000 Archiv attempts to dismount all segments of specified depository database/s. For more information see the topic On-line access to data from depository databases. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
DP ON/OFF | Debug Pipe - shows/hides the course of communication with D2000 Server (only if the process window is displayed on the desktop). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
DROP_LIST path+filename | Creates the file (defined by the parameter path+filename) containing SQL commands to delete tables, which are not used by the archive configuration. If the time slices are enabled, the file will contain also the commands to delete respective rows of the table ARC_SLICE, which contain information about the time slices corresponding to tables that are to be deleted. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Manual loading of archive cache (only available for isochronous cache mode) by reading values from the archive database. Archive cache loading can be also automatic after startup - for more information see the description of parameter IsoCacheAutoFill. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| For the selected object(s), their ClearTime is set to a value of several hours in the past, which means that a periodic delete of object's data should occur shortly - within a minute (unless it is disabled for some reason, e.g. if the time slices are enabled, it can depend on parameters DeleteInSlice0 and DeleteInSlices). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UNFREEZE | FREEZE command causes the writing and calculating tasks of the archive stop processing the requests for a period freeze_seconds. Within this time, another task (deleting) will list the number of requests (primary and calculated) in the queues. After the elapsing of the freeze_seconds time, the processing of values will be restored. If the report_seconds parameter is entered, the deleting task continues to list the number of requests in the queues for this period. FREEZE command is primarily used for performance tests (testing the maximum speed for processing the requests under load). Before its use, you should realize that it does not influence reading from the archive, but during its execution, the writing to the archive (so the newest values are not available when reading) and the calculations are not executed for the freeze_seconds period. In redundant systems with 2 and more archives, we recommend executing the FREEZE command on a passive instance, so that the functionality of the archiving subsystem will not be affected. UNFREEZE command (without parameters) is used for aborting inactivity that was caused by the FREEZE command. Kotva | | import_data | import_data | IMPORT_DATAActivates the D2000 Archiv process to import external data, e.g. Importing archive databases from D2000 V3.65 (OS/2)command (without parameters) is used for aborting inactivity that was caused by the FREEZE command.||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The parameter allows showing the list of depository databases used by the process D2000 Archiv. The contents of the list depend on the used platform - Sybase, PostgreSQL, or Oracle. Parameter id:
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
LOAD_TREZOR path+filename [mask] [from] [to] | On-line depository database import (Sybase only) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Sybase platform: The path+depository_name parameter defines the path and name of the depository database to be mounted. The name may contain "*" and "?" characters to define a mask. If more files match the specified mask, all these will be mounted. For more information see the topic On-line access to data from depository databases. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
MOUNT_TREZOR trezor_name [SEGMENT seg] [WRITE] MOUNT_TREZOR IdFrom IdTo [SEGMENT seg] [WRITE] | Oracle platform: The parameter Id (trezor_name) defines the number (name) of a depository database to be mounted. The name of the depository database is the name of depository tablespace (e.g. MYAPP_TS_TREZOR15 or MYAPP_TS_TREZOR15_02) or the name of tablespace's datafile (e.g. MYAPP_TS_TREZOR0015_S02_20040801.ORA). The IdFrom and IdTo parametersallow mounting a sequence of depository databases. The SEGMENT Seg parameter (where Seg is the number of the depository database segment) allows mounting a single depository database segment. If the MOUNT_TREZOR command is used without the SEGMENT Seg parameter for depository database with segments enabled, the process D2000 Archiv attempts to mount on all segments of specified depository database/s. The parameter Write can be used to mount the depository database (s) for writing (for depository database synchronization through the Arcsynchro tool). For more information see the topic On-line access to data from depository databases. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
MOUNT_TREZOR IdFrom IdTo [SEGMENT seg] [WRITE] | PostgreSQL platform: The parameter Id specifies the number of a depository database to be mounted. The parameter SEGMENT Seg (where Seg is the number of the depository database segment) allows mounting a single depository database segment. If the MOUNT_TREZOR command is used without the SEGMENT Seg parameter for depository database with segments enabled, the process D2000 Archiv attempts to mount on all segments of specified depository database/s. The parameter Write can be used to mount the depository database (s) for writing (for depository database synchronization through the Arcsynchro tool). For more information see the topic On-line access to data from depository databases. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
OPTIMIZE_QUEUE | Reduction of the number of calc requests in the archive queue. If for some reason, the number of requests in the archive queue has increased (for example, due to the arrival of old values from the communication), this TELL command can reduce duplicate requests. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Creates a file containing the descriptions of pending requests. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Recalculates the values in the statistical archive. Mask - defines the list of objects, which are to be recalculated. If the specific row and/or column of the structured archive is recalculated, it is possible to specify parameters Row and Col (if unspecified, their default value is 0, meaning "whole row/column"). The parameters <From, To> define a time interval to be recalculated. If the end time is not entered, the current time will be used. Time format is dd-mm-yyyy [hh[:mi[:ss[.mss]]]]. Optional parameter BACKGROUND (implemented in version 7.02.006) puts the recalculation to the auxiliary calc task (see the archive parameter RecalcImmediateDepth). The parameter is recommended for long-lasting recalculation of historical values that are supposed to be performed in the background while the archive still continues archiving real-time data. Note: If the parameter RecalcTimeIntervalLimit has a non-zero value and the time interval <From, To> is longer than RecalcTimeIntervalLimit hours, the parameter BACKGROUND is mandatory, to ensure that the recalculation will be performed by auxiliary calc. This behavior is implemented as a protection against overloading the main task by recalculations. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Premature disconnection of the current depository database. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The command is used to force the reading of the last values of the specified objects from the archive database. Objects can be specified by name/mask and by type:
If e.g. in the test environment the inserting of values of script-filled archives is not possible, but these are inserted into the archive database by the arcsynchro utility, it is possible to execute this command after the insertion is completed (e.g. RELOAD_VALUES * STATISTIC). Subsequently, a read (e.g. of all script-filled archive objects) is performed and recalculations of archive objects that depend on the read objects can be initiated. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| If the time slices are activated, the command causes the archive to review all time slices of simple archive objects according to the defined HOBJ or mask and to delete the time slices without data. The command is used to clean up the archive database from empty time slices that were created due to the error of the archive. This error was repaired in the supported versions on June 8, 2015. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| On-line reorganization of archive database. The command compacts all archive tables (same as the Oracle command ALTER TABLE MOVE or the Sybase command REORGANIZE TABLE INDEX or the PostgreSQL command VACUUM - see the PG_ReorganizeSlice parameter). Note: For Oracle, PostgreSQL, and Sybase 8.0 (and above) platforms only. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| On-line reorganization of archive table of an object with specified HOBJ or with a name matching the specified mask. If the parameter tablespace is also defined, the given archive table will be moved to the specified tablespace. If time slices are on, all slices of one archive object will be reorganized/moved unless a slice number slice is specified. Note 1: The parameter tablespace can be used on Oracle and PostgreSQL platforms only.
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
REORGANIZE ON | Enables the reorganization of the archive database (same as running the process D2000 Archiv with the /DBCY parameter). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
REORGANIZE OFF | Enables the reorganization of the archive database (same as running the process D2000 Archiv without the /DBCY parameter). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
REORGANIZE ACTIVE | Enables the reorganization of the archive database in the active mode only (same as running the process D2000 Archiv with the /DBCA parameter). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
REORGANIZE PASSIVE | Enables the reorganization of the archive database in the passive mode only (same as running the process D2000 Archiv with the /DBCP parameter). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
REORGANIZE SHRINK | Enables the alternate mode of the reorganization of the archive database - only for Oracle 10g and above (dame as running the process D2000 Archiv with the /DBCS parameter). Note: To enable the original mode, use the REORGANIZE MOVE command. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
REORGANIZE TableRowLimit rowLimit | On-line change of the parameter ReorganizeTableRowLimit is used for the automatic reorganization of the archive database. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
REORGANIZE TableTimeLimit timeLimit | On-line change of the parameter ReorganizeTableTimeLimit is used for the automatic reorganization of the archive database. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The command allows the user to change the dynamic cache size to speed up the calculation of statistical historical values while the process D2000 Archiv is still running. Note 1: The initial cache size can be specified by the parameter MaxCacheSize in the process D2000 Application Manager. Note 2: The command SET_CACHE also changes the value of the parameter MaxCacheSize in the registry. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
name_parameter value_parameter | The SET_OPTION command controls the following configuration and start-up parameters of the process D2000 Archiv:
Note: For parameters that are stored in the Registry database the SET_OPTION command will change the value of configuration parameters not only in the archive but also in the Registry database. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Shows dynamic information on the specified object (current value, last sent value, time of next calculation for periodically archived objects, time of periodic deleting, parameters, and content of cache) on the text console of the D2000 Archiv process. Note: The command is mainly intended for D2000 system diagnostic purposes. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| If the archive cache is enabled, the result is a list of top count historical values having the most values in the archive cache. For every value, the following properties are displayed: HOBJ, name, number of items, and time interval of values in the archive cache. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Shows various information about the D2000 Archiv process and the archive database. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Creates the file path+filename with statistical information, i.e. number of values for individual historical values from the last n-hours. The path+filename file will be created by the D2000 Archiv process, so its naming is OS-dependent (e.g. D:\stat.txt on Windows, /tmp/stat.txt on Linux). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The command redirects the standard output to a new output. Example: | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Deactivates a feature of the process D2000 - import of external data. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
STOP [NOQUEUE] | Stops the process D2000 Archiv. All unsaved values from the request queue are to be automatically stored on the disk and during the next start of the process, the values will be read from the disk. The current values of historical values are to be stored in the table SAVED_LAST_ROWS to quicken the next start of the process. If the NOQUEUE parameter is used, the unsaved values from the request queue will not be stored in the file (it speeds up stopping the process with a large number of unprocessed values). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
TIMESTAT START TIMESTAT RESTART TIMESTAT SHOW TIMESTAT SHOWLONG TIMESTAT SHOWSTART TIMESTAT STOP | Starts (START), stops (STOP), restarts (RESTART), shows (SHOW), shows and restarts (SHOWSTART) or shows the time statistics of reading task(s) in long time format, including the days (SHOWLONG). After starting the statistics, the database reading task(s) will start the measuring time, spent in various parts of the reading procedure. These values can be used for tuning by system specialists. Time statistics are displayed per reading task and if ReadThreadsCount > 1, also totals for all read tasks are shown. Note: When time statistics are on, reading from the archive may be several per cent slower due to time measuring. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| PostgreSQL platform: The command is used to compress the data of existing depository databases. See the Depository Data Compression chapter for more information.

| Debug Info for values - enables/disables displaying information about the evaluation of:
| ||||||||||||||||||
DP ON/OFF | Debug Pipe - shows/hides the course of communication with the D2000 KOM (only if the process window is displayed on the desktop). | ||||||||||||||||||
GETKOMARCDEPTH | Gets the timestamp of the oldest data stored in the KOM Archive. | ||||||||||||||||||
| Reads historical values from a device - StationName station. The values from the specified interval will be read. The parameter EndTime is optional and if is not entered, the current time will be used. Time format ("BeginTime", "EndTime") is "dd-mm-yyyy hh:mi:ss". This feature is supported only by some communication protocols (Datalogger ESC8800, ESC8816, UNIP_TS ...). Warning: This is not a function of KOM Archiv but it is the reading values directly from a device! NORECALC parameter causes the archive to not execute the calculation of calculated archive objects, the values of which are calculated from the values acquired by this calling of a TELL command. For some protocols (OPC DA, OPC HDA, and IEC 870-5-104), a parameter mask "M:" can be used, which is used to read the archive values only for selected I/O tags which match the mask, from the StationName station. | ||||||||||||||||||
| The command allows switching between the primary (OFF or PRIMARY) and backup (ON or BACKUP) devices for lines of categories "SerialOverUDP Device Redundant", "SerialOverUDP Line Redundant", and "SerialOverUDP System&Line Redundant", or discovering the active device (QUERY). The active device is used to write UDP packets and packets received from it are processed. Data received from the inactive device is ignored. Similar functionality is also supported for lines of the "TCP/IP-TCP System Redundant" category - the TCP connection is connected to a primary or backup device. The third parameter (numbers 1-4) specifies the subline. For a line of category "SerialOverUDP Device Redundant", it need not be specified or must be equal to 1. For a line of category "SerialOverUDP Line Redundant", it can be equal to 1 (the device on the Primary line is set) or 2 (the device on the Secondary line is set). For a "SerialOverUDP System&Line Redundant" or "TCP/IP-TCP System Redundant" category line, it can be equal to 1 - 4 (the device on the Primary/Secondary line of the system A/B is set). If an active device is detected (QUERY) and the third parameter is not entered, all active devices are listed (1, 2, or 4 depending on the line type). The command is also applicable on the OPC UA Client line in the OPC Unified Architecture Data Access Client protocol for Client Type=Default. Using Client protocol for Client Type=Default. Using the command, it is possible to find out which of several specified hosts the D2000 KOM process is connected to (QUERY) or to force a connection to a specific one (ON, third parameter set to 1 .. N). The command is also applicable on RFC2217 Client, TCP/IP-TCP and TCP/IP-TCP Redundant lines. With the help of the command, it is possible to find out which of several specified hosts the D2000 KOM process is connected to (QUERY, or QUERY PRIMARY/BACKUP) or to force a connection to a specific one (ONPRIMARY/BACKUP, third parameter set to 1 .. N). Examples of use: | ||||||||||||||||||
| The command can be used only for the lines of Serial (asynchronous serial lines) and RFC2217 Client categories. The command stops the communication (CLOSE) and disconnects the communication port. Then the port can be used by other programs, e.g. diagnostic or configuration tools. Stations on the line are to be in the Communication error state. The communication will be recovered either using the command LNSTAT OPEN or after restarting the whole communication process. | ||||||||||||||||||
LNTRACE DEC/HEX | Enables the decimal/hexadecimal format of line listening. The default format is hexadecimal. | ||||||||||||||||||
READKOMARC ["BeginTime"] ["EndTime"] | Reads the values from KOM Archiv. There are transferred all old values from the specified interval. The parameter BeginTime is optional and if it is not entered, the data from all history depth of KOM Archiv will be read there. The parameter EndTime is optional and if it is not entered, the current time will be used. If the parameters BeginTime and EndTime are not defined, there will be sent just the values, which have not been sent. If at least the parameter BeginTime is defined, there will be sent all values within the specified interval. Return codes:
| ||||||||||||||||||
| The command de-configures the object (line or station) and its descendants (stations, I/O tags) and reloads them. The command can be used to apply configuration changes that would otherwise require restarting the KOM process. The command is currently implemented for protocols:
| ||||||||||||||||||
| Resets the statistics of given line / station - the system structured variable SV._System_LinePerformance / SV._System_LinePerformance. It is executed immediately but it will be visible after the process D2000 KOM sends new statistics to the process D2000 Server (periodically every 10 seconds). | ||||||||||||||||||
| Dynamic change of the I/O tag address. The parameter name specifies the I/O tag. It can be entered as the object name (e.g. "M.CoolantTemperature") or the object HOBJ (the syntax requires the character '$' before HOBJ, e.g. "$278"). The parameters address1 and address2 define the new I/O tag address. Change of address will be performed only in internal data structures of the KOM process. It is not sent, in a centralized way, to the server, i.e. changed address is valid until the restart of the KOM process. After this, the value from the initial configuration will be used again. Return codes:
Dynamic change of the I/O tag address is implemented only for a limited group of communication protocols: | ||||||||||||||||||
SETSTADDR StationName|StationHOBJ "address" | Dynamic change of station address. The first parameter specifies the station. It can be entered as the object name StationName (e.g. "B.Station") or station ID StationHOBJ. The "address" parameter defines its new address. Change of station address will be performed only in internal data structures of the KOM process. It is not sent, in a centralized way, to the server, i.e. changed address is valid until the restart of the KOM process. After this, the value from the initial configuration will be used again. Return codes:
Dynamic change of address is implemented only for a limited group of communication protocols: | ||||||||||||||||||
SHOW TAG TagName/TagHOBJ SHOW STATION StationName|StationHOBJ SHOW NAN | Enables debug information for the specified I/O tag/station. The command requires either the name or HOBJ of the I/O tag/station. The debug information is usable for D2000 System developers. The SHOW NAN command displays all I/O tags whose value (current, last telemetry, or last valid) is NaN (unspecified type). | ||||||||||||||||||
SHUTDOWN WINNT | Restarts the computer with the D2000 KOM process (the process must be running). | ||||||||||||||||||
| For the Microtel 700 protocol, it explicitly activates (ON) or deactivates (OFF) an alternative communication route for a station named StationName (e.g., "B.Station"). | ||||||||||||||||||
| Starts a data recording into a subdirectory (application directory) with the name dir_name_only. If the directory does not exist, it will be created. If this TELL command is run from the D2000 Server, firstly, the file dodm_values.dat containing the initialization values of DODM objects is recorded and then the D2000 Server will send this command to clients. Data are recorded within the time period <begin_time, end_time>. If <begin_time> is not set, data are recorded immediately. Example: These four data files (it relates to four hourly intervals) are the result of recording: Note: The TELL command uses "dd-mm-rrrr hh:mm:ss" format for the parameters of DateTime type. | ||||||||||||||||||
| Stops a data recording immediately, it is not necessary to wait for end_time. If the recording is not in progress, an error will be returned. Note: It is possible to start up this TELL command from the D2000 Server, as well as directly from the clients (currently only from the D2000 KOM and Gateway Client processes). | ||||||||||||||||||
| Starts a data replaying from a subdirectory (of application directory) with the name dir_name_only. If the directory does not exist, an error will be returned. If the command is run from the D2000 Server - at first, the dodm_values.dat file containing the initialization values of DODM objects will be recorded by the D2000 Server, and then the D2000 Server will send this command to the clients with /NOW parameter. It replays all data (in data files) with the time stamp >= begin_time. The timestamp of data represents a particular time from the recorded time period. The time of data replaying must be from the range of the recorded time period. Example of data replaying:
Note: This TELL command uses the "dd-mm-rrrr hh:mm:ss" format for the parameters of DateTime type. | ||||||||||||||||||
| Stops a data replaying immediately. If the replaying does not work, the error will occur. Note: There is possible to start up this TELL command from the D2000 Server, as well as directly from the clients (currently only from KOM client). | ||||||||||||||||||
STDOUT output | The command redirects the standard output to a new one. Example: | ||||||||||||||||||
STOP | Stops the D2000 KOM process. | ||||||||||||||||||
| Enables the communication (the parameter START) or disables the communication (parameter STOP) with the StationName station. The station will get the StON (START) or StOFF (STOP) value. | ||||||||||||||||||
| For protocols based on periodic polling of I/O tags (request-response protocols): the command generates one or several requests for priority reading of all I/O tags on a specified station. The Number parameter defines the number of requests, possible value is within 1...5. If the parameter is not specified, a single request will be generated. For protocols based on sending of changes (change-based protocols): the command generates one or several requests for the reading of all data. The command is implemented for a selected set of communication protocols:
|
...
DP ON/OFF | Debug Pipe - shows/hides the information about communication with D2000 Calc (only if the process window is displayed on the desktop). | ||||||
RESET_STATISTICS | Resets the counters for evaluating the statistical data. | ||||||
STATISTICS path+file | Writes statistical data about individual I/O tags into a file. The file contains the following information: I/O tag name, number of recalculations and number of new values broadcasted into the system. The counters are reset while starting the process D2000 Calc or using the command RESET_STATISTICS. | ||||||
STDOUT output | The command redirects the standard output to new one. Example: | ||||||
CALCINFO ON|OFF clcName [row] | The command is used to determine the reason for calculating the eval tag that has the Calculation method parameter set to At change or Trigger value. The command ensures (CALCINFO ON) that into the LOG file of the process will be continually written information about the reason for the calculation of the eval tag. The CALCINFO OFF command terminates the continuous log to the LOG file. It is used for the eval tags that have the Calculation Method parameter set to At change or Trigger value. Record in the LOG file contains:
Parameters: clcName - the name of eval tag row - specifies a row number for a structured eval tag. If not specified, the replacement value is 0 and all rows will be tracked. Example (the content of LOG file): TELL command: CALCINFO ON P.OnSec In the LOG file, there is a record that the information is about the calculation of the calculated P.OnSec object. The value of the object changed from HOBJ=20 (VALUE IN $20). Next, the individual attributes of the input value are displayed. Output value attributes are displayed after a row containing VALUE OUT content.
| ||||||
| The command enables to compare the values of destination columns (of structured variables), configured in the eval tags, with the values that were calculated by D2000 Calc. When specifying the particular object of Structured variable type, for which the comparison should be done, the value of parameter DestId, or also ColIndex for the particular column, must be a non-zero. It is followed by the optional keywords from the list: Detail, Debug, Ignore_Time, ReCalc0s, ReCalc1m. You may find the detailed information in the document Checking values of destination columns. Note 1 : This command is mainly used for diagnostic purposes in D2000 Systems. Note 2: Command is supported only in version D2000 V8.0.5. | ||||||
| It enables displaying a configuration and the current status of a particular eval tag. The eval tag is defined as an input parameter either through its ID (HOBJ) or mask. If several eval tags match the mask, the first 20 tags will be displayed. If Row parameter is different than 0, it must be the eval tag, the values of which are written to a destination column of the structured variable. For common eval tags (those that have not a destination column) the Row parameter must be 0 or not specified. The log format is identical with the format [Calc], which is stated in the article Checking values of destination columns, Example 3. | ||||||
GET_SOURCE_VALUE HOBJ Row Col | It enables the displaying of the inputs into the calculation providing they are the inputs from the structured variables. The log format is identical with the format [DestVal] Checking values of destination columns, Example 3. Note: This command is mainly used for diagnostic purposes in the D2000 systems. |

SHOW_HANDLE [table/database/structure_definition HOBJ] or [table mask] | Shows information on open descriptors. For more information see the chapter DBManager - debugging. |
SHOW_CONNECT [database HOBJ [connect/transaction ID]] or [database mask [connect ID]] [DETAIL] | Shows information on open connections. For more information see the chapter DBManager - debugging. |
SET_WATCHDOG database_mask seconds [NONTRANS] | Switches on the monitoring of connections that perform SQL commands longer than the specified time seconds. This information can be used for the profiling of applications and for the detection of slow SQL commands. If a NONTRANS clause is specified, transactional connections are not monitored. Starting with version 10.1.39, after After the long-running SQL is finished, detailed info about it is written to a log file. More information can be found in chapter D2000 DBManager - debugging. |
SET_WATCHDOG_QUEUE database_mask seconds [NONTRANS] | Switches on the monitoring of database actions that take longer to be processed (including waiting in queues of DBManager) than the specified time seconds. After such a database action is finished, detailed info about it is written to a log file. If a NONTRANS clause is specified, transactional connections are not monitored. More information can be found in chapter D2000 DBManager - debugging. |
MONITOR_TRANS SHOW {ALL/<id>} [<file_path>] MONITOR_TRANS ON <history_depth_sec> MONITOR_TRANS OFF MONITOR_TRANS RESET | The mechanism for monitoring of the transactions. Columns in the list: Note: After starting DBManager, the monitoring is switched off. |
MONITOR_CONNECTS SHOW {ALL/<id>} [<file_path>] MONITOR_CONNECTS ON <history_depth_sec> MONITOR_CONNECTS OFF MONITOR_CONNECTS RESET | Monitoring the connections. Columns in the list: Note: After starting DBManager, the monitoring is activated with the time-depth history of closed connections which is 3 hours (10 800 seconds). |
REFRESH_TABLES seconds | The command is intended for use on the PostgreSQL platform. It is used to close and reopen cursors used in page access to tables so they don't block table vacuuming if these cursors are open for too long. Typically, these are schemes with browsers, which are e.g. open for several days. The parameter seconds is the minimum age of the cursor in seconds to be reopened (e.g. 86400). |
TIME_STATISTICS database_mask [DETAIL] | Displays statistics of execution of individual database action types per-database or per-table (if a DETAIL parameter is specified). For more information see the chapter DBManager - debugging. |

GETOLDVAL remoteObjectMask "BeginTime" ["EndTime"] ["NORECALC"] GETOLDVAL "remoteTagName[row]^item "BeginTime" ["EndTime"] ["NORECALC"] | Reads the values of the remote tag within a specified interval. If the EndTime parameter is not specified, the current time will be used as the default value. Time format ("BeginTime", "EndTime") is "dd-mm-yyyy hh:mi:ss". The command may be used for example after a failure or stoppage of the application, which the D2000 GateWay Client process belongs to. It allows transferring the values from the archive of the remote application to the archive of the application. The only requirement of the value transfer is that the values of corresponding objects have been stored in the archive of the remote application. The first form of the command reads all values transferred by specified remote tags (as well as structured objects). The second form of the command reads all the values of several objects according to the mask. The third form declaration reads the values of a part of structured objects partiallyobject. The parameter item specifies a column of the destination structure (see the Destination structure parameter in the configuration of the remote tag). When a single row (column) must needs to be read, use the following:
The TELL command must always be executed in the transaction mode - the COMMAND action (within the D2000 System Console process, the command is automatically executed in the transaction mode). After the command is executed, the values that were transferred will be stored in the archive and the D2000 Archive automatically recalculates corresponding statistics. The NORECALC parameter can be set at the end of the GETOLDVAL. In this case, the statistic calculations will not be executed by the D2000 Archiv process. | ||||||
DI ON/OFF [HOBJ/mask] | Debug Info for remote objects - enables/disables displaying the information about processing the values of objects with specified HOBJ or with the name matching the given mask. Note:if the gateway client is run in a transparent gateway mode, use the TRGTW command to display debug information. | ||||||
| Shows dynamic information on the specified remote object(s) on the text console of the process D2000 Gateway. Note: The command is mainly used for D2000 system diagnostic purposes. | ||||||
TRGTW | Debug command for transparent gateway mode. The command lists the names of objects and their HOBJ on the local and remote systems. | ||||||
START_RECORD dir_name_only [begin_time] end_time | Starts recording of values read from theGateWay Server. For details see the command description for the D2000 KOM process. Note: Replaying of recorded values by the D2000 KOM process is possible if the GateWay Client was running in a transparent gateway mode during the recording. | ||||||
STOP_RECORD | Instantly stops recording of values read from the GateWay Server. For details see the command description for the D2000 KOM process. | ||||||
