Hearing that an application is going to be upgraded from 12.1 to 12.2.
Vendor is saying they will create a “blank, no patched” 12.2 $ORACLE_HOME, and
then upgrade the database.
They will test this for a while, and if everything is fine, THEN they will
apply the patch.
I’ve never heard of such a thing and have been working on Oracle databases
since 1983, version 4.0.
Is there logic in this? We try to keep all databases at N-1 on patching.
