I patched my database (Windows database bundle patch 184.108.40.206.201020 (31654782)).
There are 6 instances on the server. After the patch, the UPGRADE CATALOG command I ran on RMAN for the first 5 instances was compiled in 2-3 minutes each. But it has been going on for 1 hour for the last intance. Is there a way to speed it up or is it a bug?
