HP Data Protector Operations Guide

Uncomment the option in the
global file, and select 0 or 1 to enable the option:
Instead of the automatic scheduled purge preview, it is recommended to script or manually run a
purge preview session once a month, using the following command:
C:\Program Files\OmniBack\bin>omnirpt –report db_purge_preview
Analyze the output of the
db_purge_preview report by looking at the column Est. Obs. If you see
that there are clients with values over 1,000,000, a filenames purge session should be executed
for that Cell Manager.
Note: If you set the
DbPurgeCheck to 0, it is highly recommended to do it manually or scripted. If
you do not do this, you will not be notified if a purge is needed and you may run into problems.
IDB Purge
Keep using the default scheduled db purge session of dcbf, messages and sessions. No changes
are required.
For heavily loaded cells, perform a filename purge twice a year if possible, but once a year at the
minimum.
The filenames purge should be combined with a
writedb/readdb in order to reduce the IDB size
and eliminate fragmentation.
First run the filenames purge then perform the
writedb/readdb.
Note: This operation might take several hours in which no Data Protector operation are possible,
so plan enough downtime for this purge session.
