RMAN catalog backup with controlfile

Lets simulate a backup we want to add to the controlfile, by removing one

(could not see uncatalog command), so some backup files at the host level then

• crosscheck backup;
• delete expired;

Then use catalog command to add backup pieces back into RMAN eco system, can provide a path to make it easy:

• CATALOG START WITH ‘<PATH>’

or

• CATALOG BACKUPPIECE ‘<PATH>’;
