Oracle database patching

in Database Install/Upgrade/Opatch (MOSC) 6 commentsAnswered

I'm new to Oracle patching.

I have an Oracle Database (19c Enterprise Edition Release 19.0.0.0.0 - Version 19.25.0.0.0). I have two quarterly patches to apply (1st and 2nd quarter 2025). Wondering about the sequence. Do I apply the 1st qtr database patch, the 1st qtr OJVM patch, 2nd qtr database patch, the 2nd qtr OJVM patch and then do the post installation process (datapatch) or do I need to do the datapatch between each patch. Also, do I need to run the opatch prereq CheckConflictAgainstOHWithDetail command and rollback any obsolete patches before each patch? I have a limited time window to do this and want to be as efficient as possible.

Howdy, Stranger!
