The JAMS_PURGE job is responsible for purging old records from the History file.

Parameters

Number of days of History to retain

This parameter specifies the maximum number of days which a Job execution history record should be retained.

Minimum Number of Records per Job

Specifies the minimum number of History records to keep per Job. This can prevent the purging of History records which are older than the specified maximum number of days. This is useful when a Job is run infrequently.

Maximum Number of Records per Job

Specifies the maximum number of History records to keep per Job. This will cause records to be purged even though they are not older than the specified maximum number of days. This is useful for Jobs which run many times a day.

Description

This job purges old records from the JAMS History file. The completion date of each history record is compared to the date defined by the parameter to this Job. If the History record is older than this date, it is eligible for deletion.

At least one history record for each Job is maintained, no matter how old it gets.

This Job does not produce any reports, but the Jobs log file will contain a message which tells you how many history records were deleted.

After the History file has been purged, the JAMS_SCHEDULE process is stopped and a CONVERT/RECLAIM is performed on the History file.

This job also creates a new JAMS.LOG file and purges JAMS.LOG to three versions. The JAMS.LOG file is used by the JAMS Monitor, Schedule and Network processes to log events.
