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.

ON - activates the monitoring. <history_depth_sec> means a time-depth history of closed transactions.
OFF - deactivates the monitoring
RESET - resets the list of transactions (including the opened ones)
SHOW - shows either the list of transactions including the history (ALL) or the particular transaction (<id>) to a console or file <file_path> in CSV format separated by ";"

Columns in the list:
- ID (transaction identifier)
- time, task, traceback (time the last operation within the group of identical ones, task, traceback in the internal code)
- comment, count (the last comment and the number of consecutive identical operations) (the identical operations has the same task and traceback)

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.

ON - activates the monitoring. <history_depth_sec> represents the time-depth history of closed connections.
OFF - deactivates the monitoring
RESET - resets the list of connections (including the opened ones)
SHOW - shows either the list of connections including the history (ALL), or the particular connection (<id>) to a console or file <file_path> in CSV format separated by ";"

Columns in the list:
- ID (auxiliary identifier of connection)
- logon_time, logon_task, logon_traceback (time of connection, task and traceback in internal code)
- logoff_time, logoff_task, logoff_traceback (time of disconnection, task, and traceback in internal code)
- comment (the last written comment for the given connection, e.g. traceback in ESL code)

Note: After starting DBManager, the monitoring is activated with the time-depth history of closed connections which is 3 hours (10 800 seconds).

The command allows you to close and reopen connections to the database that are not currently in use (there is no transaction in progress or a cursor in use).

Note: This command was implemented to work with temporary tables in PostgreSQL. These are only dropped when the database connection ends, and while they exist, the data in them is not visible outside the database connection that inserted them, so they cannot be accessed by vacuum, and therefore internal transaction IDs (XIDs) can be exhausted if a connection is open for a long time.
