Purging historical job execution information
Periodic statistics entries that are not updated for a specified duration of time are
considered obsolete and are removed from the database. The user specifies the
duration of the time by setting the RunInfoStatsPurgeDays parameter (Type: cms) to
the required number of days. For more information, see the system parameter
section.
The CONTROL-M Configuration Manager server automatically purges the database
of obsolete statistics records at specific intervals. The user determines the interval
between purges by setting the RunInfoStatsPurgeInterval parameter (type: cms) to
the required number of minutes. For more information, see the system parameter
section.
