I have two ORACLE_HOME. One for 10.2.0.1 and another for 10.2.0.4 (After applying patch set). 10.2.0.4 ORACLE_HOME has no database. I am planning to create few databases under 10.2.0.4 ORACLE_HOME. Is it necessary, to run catupgrd.sql each time after creating a new database?
I personally can't see any value in a desupported and not fully patched database so I can't imagine why you are spending your time on this but the answer to any patching question starts with "read the notes" that came with the patch.
