OPATCH prereq failed with checkConflictAgainstOHWithDetail not executed

Recently I was working on applying a PSU One-Off Patch, before applying patch it is necessary to get conflict resolution with existing patch information.

I was running below command to get one-off patches conflict with the PSU and received error

$ opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir ./9352164

Solution: You will see this error when you don’t have a latest Opatch version. Go to My Oracle support and download the latest patch.

Irrespective of the Oracle version (9i,10g,11g) you will see this issue when you don’t have latest Opatch version.

Steps to install the newer version of OPATCH
1. Copy the patch into ORACLE_HOME
2. Rename the old “Opatch” directory
$ mv OPatch OPatch_bak
3. Unzip the file patch
4. Check new OPatch version
$ opatch version
You should be able to see new Opatch version.
