We tested the RMAN crosscheck command when
testing DR replication and although I thought we were going to need it, we
didn't. If I can remember correctly, the RMAN database holds some
information about the image the data is on, and the location of that image
(MediaID or DSSU location), however when you go to do a restore, it requests the
image, not the location, and Netbackup is responsible for supplying the
correct source. To make our DR work, we only have to make two
changes.
1) Change the client name to the original source client
(our DR servers have different names then Prod) and reboot (if
windows)
2) Account for any time difference when issuing the
RMAN restore commands (Our DR site is 3 time zones behind, so we have to add 3
hours to the restore requests.)
Hope that helps.

Oracle agent using RMAN crosscheckcommand
Has
anyone had experience using the RMAN crosscheck command to keep the oracle
RMAN catalogue in sync, particularly when duplication is involved. Its highly
probable that the original RMAN entry will point to an expired image ( although
the 2nd copy is still active)
