Frequently Asked Questions about filenames purge
Question 1:
Will the force option cause the filenames purge to remove protected data?
Answer 1:
No, a force purge will not remove any protected data from the DP IDB.
A purge without the force option looks for obsolete records for a hostname and only purges those
records if there are more than 1000000 obsolete entries.
The –force switch causes DP to purge all expired records even if there are less than 1000000 expired
records for a hostname. For this reason the command is much more effective if the –force switch is used.
Question 2:
What happens to scheduled backups that are due to start while the omnidbutil -purge -
filenames is running.
Answer 2:
Scheduled backups will not start if a filename purge is in progress.
The consecutive running of a dcbf Purge followed by a fixmpos
omnidbutil -purge –dcbf, deletes the dcbf records that are no longer required. However, the
mmdb will still have mpos records referring to these removed dcbf records.
Therefore, from time to time we suggest the consecutive running of a dcbf Purge followed by a fixmpos.
omnidbutil -fixmpos requires exclusive access to the IDB, therefore the consecutive running of
these commands must be done when no backups are in progress.
Example of messages seen at the command line
omnidbutil -purge -dcbf
DONE!
omnidbutil -fixmpos
DONE!
Note:-
See Appendix D for information about another manual purge that may, in
some circumstances, be required.
Appendix A
