Use ED300 to purge event history. Event history should be purged regularly to keep the EDEVENT (Unix/Windows) or DBEDEDE (System i) and EDEVENTDTL (Unix/Windows) or DBEDEDT (System i) database tables down to a reasonable size.
To purge event history
1. Access Purge Event History (ED300).
2. Assign a job name.
3. Specify the number of days of event history that you want to keep.
4. Add the job and click Submit. ED300 will write the purged data to these locations:
LAWDIR/applicationproductline/edi/purged/EDEVENT.ccyymmddhhmmss
-or-
LAWDIR/applicaitonproductline/edi/EDEVENTDTL.ccyymmddhhmmss.
These are comma-delimited files that can be backed off onto other media and can be reloaded into EDEVENT (Unix/Windows) or DBEDEDE (System i) and EDEVENTDTL (Unix/Windows) or DBEDEDT (System i) if they should ever be needed again.
