Because Policy and Distribution Services logs all successes and failures for the Server Policies or TED components, ZFSLOG.DB can quickly grow in size. Therefore, you should periodically purge ZFSLOG.DB.
Purging of policy information is done automatically according to the schedule you set whenever ZFS.NCF is started on a server where ZFSLOG.DB resides.
You can manually purge a selected database of all TED information older than a specific date and time.
To manually purge a database:
In ConsoleOne, right-click the database object > click Purge.
In the Purge Database dialog box, select a date and time > click OK.
