HP Data Protector IDB Purge Best Practices

While a command that requires exclusive access to the IDB is running, scheduled DP backups will not

start.

If the Cell Manager where you want to run the command requiring exclusive access to the IDB is part

of a MOM you have to stop backups on all Cell Managers that are part of the MoM.

Appendix B

Further information about the IDB Daily Maintenance

The daily maintenance runs the following commands:

• omnidbutil -purge -sessions <days>

• omnidbutil -purge -messages <days>

• omnidbutil -purge -dcbf

• omnidbutil -purge -mpos

The omnidbutil -purge -mpos purge is available by default on DP 6.11. The purge is not

available on DP 6.1, DP 6.1 customers should upgrade to DP 6.11. DP 6.0 requires one of the

following patches or their successor.
