Enables the debug information on the status of the Oracle cluster.
The parameter can be used only when the database TNS points to cluster and contains FAILOVER section (recovering the connection after one of the instances of Oracle cluster fails). If the FAILOVER section is not included in the database TNS, no debug information will be generated on a failure or disconnecting a cluster instance.

Warning: The parameter can be used just for dbmanager_ora.exe.

Support for long strings (e.g. for working with CLOB columns of Oracle database). By default, D2000 DBManager works with strings upto 4000 characters long. With this parameter, a reserved maximum size for a string can be changed.
Note: Increase of reserved size will affect memory consumption.

1. Two (or more) archive processes (SELF.ARC), where one is connected to the HS Server, the other (s) is connected to SBS Server (s). If SELF.ARC is connected to the SBS Server, it works in the ReadOnly mode. If it is connected to the HS Server, works as usual.
2. Two (or more) instance archive processes (SELF.ARC_1, SELF.ARC_2, etc.), that are connected to the HS Server. The active instance works as usual, the passive one (s) works in the ReadOnly mode.

• its D2000 server changes its state to SBS
• DbManager is run as an instance (supported since version D2000 8.0) and the instance becomes passive

Developer mode: enables the parallel running of several D2000 Server processes on one computer for development purposes. The value of <nickname> will be displayed in the topic of text console window of D2000 Server process (if the console window is visible, see the parameter /X) and it will be also added to the name of shared memory used for interprocess communication.
To avoid collision and change the standard number of TCP port (3119) all processes D2000 Server (with the exception of a single one using standard TCP port 3119 and standard name of shared memory) must be run using the parameters /P and /DM.
Example:

ServerA: kernel.exe /P:1001 /CApp1 /DMThisIsApp1
ServerB: kernel.exe /P:1002 /CApp2 /DMThisIsApp2

local connection to ServerA via shared memory: hi.exe /P:1001 /DMThisIsApp1
local connection to ServerB via shared memory: hi.exe /P:1002 /DMThisIsApp2

local connection to ServerA via TCP/IP: hi.exe /P:1001 /TP
local connection to ServerB via TCP/IP: hi.exe /P:1002 /TP

remote connection to ServerA: hi.exe /Sserver_name /P:1001 /TP
remote connection to ServerB: hi.exe /Sserver_name /P:1002 /TP

Note: Starting with the version 7.02.006 the process D2SMC supports parameters /DM and /P. Multiple instances of D2SMC can be executed, each of them connected to a different D2000 Server running in developer mode.

• /DUMP - generates the file with the basic information about process, such as threads and their call-stacks. Size of this file is quite small. Mostly, the information in this file is sufficient for analyzing the reasons of crash.
• /DUMP_MEDIUM - generates the file with the information about process and a part of memory that is formed by heap. Size of this file is bigger than when using /DUMP parameter.
• /DUMP_FULL - generates the file containing the full process image at the time of crash. Size of this file can be very large (equal to the size of the process in memory). Use this parameter only in the extraordinary situations!

Enables (+) / disables (-) displaying of debug information of given category (debug_category) on start of the process.
Debug information is designed for internal development purposes.

To enable / disable displaying of debug information and to view it you may also use the process D2000 System Console.

Warning: Displaying debug information may cause system overload.

• 1 - automatic sending of values, gained during work in the offline mode, from the KOM archive (implicit value),
• 2 - values are sent only on demand (TELL command).
• 3 - automatic sending of values from KOM archive (as the mode 1), but the statistical archive values are not recalculated.

The parameter period is optional and is given in seconds. Minimum value of the parameter is 5 s.
If period is not specified, the process D2000 KOM will simulate the values of I/O tags with the period specified by the polling parameter Delay of respective station (if Delay is not specified, i.e. 0:0:0, the values of I/O tags will be simulate with the period of 5 s.).

DbManager tries to find a connection to the database up to count-times, always with a 1 second delay. The default value is 10 times. The parameter is important when switching redundancy when the /DBSH parameter is used (the database connection is maintained by only the active DbManager) so that the database operations of initializing events don't fail because the connections to the database are not yet functional.
The original behavior (a single attempt to find a connection) can be achieved by setting / KS1.

• SK - for Slovak version
• CZ - for Czech version
• GB (EN) - for English version
• RU* - for Russian version
• KZ* - for Kazakh version
• RS* - for Serbian version

If the parameter is not entered, then language version of the process is set by the regional settings of operating system.

*The parameters apply for D2000 HI, other processes use English.

Note: For on-line help applies, if it exists for given language, it will be used, if not, English version will be used.

The parameter activates a feature that causes the calculation of eval tags and publishing of values after the redundancy switching (values can be published through the value of the own eval tag or by writing to the structure fields in the case of structured eval tags). This behavior is not desirable and is disabled by default (recalculation is not performed after redundancy is switched). If necessary, you can activate this feature by the / Q parameter.

Time is the waiting period (in seconds) of the client process for the initialization of D2000 Server. Default value is 1 second.
Note: This parameter is ignored if used together with parameters /RD or /RF.

Parameter has another meaning on Windows platform if the process is run as a service (see the parameter /X). It indicates the required service start time - from the start of the process to the successful connection to the  D2000 Server process. The historical default value was 10 seconds, therefore to keep the compatibility the start time is specified  as 9 +<Time>. The default value may not be sufficient, for example, when a process is being run remotely and connects via slow WAN network, so Windows will report a timeout starting the service.

Ensures that D2000 HI process runs in different time zone as it is set in D2000 System. As a time zone name, it is possible to use any name from tz database or define fixed offset from UTC using format "(+|-)hh[:mi[:ss]]", where hh defines number of hours, mi defines number of minutes, and ss defines number of seconds. Sign as well as number of hours are mandatory parts of offset definition, number of minutes and seconds are optional and default to 0 (e.g. "+02:30" defines offset of 2 hours and 30 minutes from UTC).

Some processes can be started multiple times as a form of redundancy in D2000 - as instance or shadow ones (D2000 Archiv, D2000 Kom, D2000 Calc, D2000 DBManager).
In that case the instance number must be written after the name of process as follows:
/WSELF,2

The system generates the process (object) name as follows:
[InstanceNr]_originalName.Suffix

Example:
[2]_SELF.ARC
Above mentioned object is dynamic and its name can be used within the structure SV._System_Proces.

Note: See the chapters Redundant archiving, Redundancy of communication process.
