Number of days before Caché purges finished journal files.
Synopsis
[Compability]    DaysBeforePurge=n
Description
The value defines when Caché purges a finished journal file (that is, a journal file that is no longer in progress). The value n is a number days that elapse before the corresponding journal files can be purged. The range is 0–100 days. The default is 2 days.
BackupsBeforePurge relates to DaysBeforePurge. If both are greater than 0, files are purged after n days or n successful backups, whichever indicates the shorter time period. If BackupsBeforePurge is 0, purging is done solely based on DaysBeforePurge; if DaysBeforePurge is 0, then purging is done solely based on BackupsBeforePurge. If both are 0, the automatic purging of journal files (and journal history) is disabled and journal files are not purged.
No journal file containing currently open transactions is purged, even if it meets the above criteria.
For details about journal files, see the Journaling chapter in the Caché Data Integrity Guide.
