UCMDB Support Tip : Postgresql.log grows out of control

In UCMDB 10.10 the postgresql.log on the Data Flow Probe may often grow out of control and this may sometimes crash the DataFlowProbe service.


This problem is planned to be addressed in UCMDB 10.10 Cumulative Update Package (CUP) 2 until then the following workaround can be used.


1. Deactivate all the jobs.
2. Create a backup of the probe logs, if needed.
3. Stop the Probe service.
4. Clear all the probe logs.
5. Navigate to x:\hp\UCMDB\DataFlowProbe\pgsql\data\postgresql.conf file.

    log_truncate_on_rotation = off (set this to on)        # If on, an existing log file with the
                       # same name as the new log file will be
                       # truncated rather than appended to.
                       # But such truncation only occurs on
                       # time-driven rotation, not on restarts
                       # or size-driven rotation.  Default is
                       # off, meaning append to existing files
                       # in all cases.
   log_rotation_age = 1d            # Automatic rotation of logfiles will
                       # happen after that time.  0 disables.
   log_rotation_size = 10MB        # Automatic rotation of logfiles will
                       # happen after that much log output.
                       # 0 disables.

6. Start the Probe service.
