                                    Apply prerequisite patch(es) [12345678] before applying interim patch 12345678.

 

Environment

Standard Oracle 19c

Cause

CPU patch does not apply as it conflicts with previous patch.

Resolution

First ensure to uninstall the Oracle JVM first, install the release update, and then reinstall the JVM.  

In the Oracle_19c_CPU2023JAN_Win64 compressed file, there is ReleaseUpdate_19.18.0.0.0_2023JAN_64bit_Win/34750795/README.  Section 4 provides the instructions how to Deinstall a Patch. 

According to Oracle’s support document, there is a procedure to deinstall “Oracle JavaVM Component Database PSU” OJVM PSU from a database ORACLE_HOME. The document provides an overview of the steps required to de-install the patch and should be read in conjunction with the OJVM PSU README from the patch to be rolled back.   There is a readme for the whole cpu and there is a readme for each sub patch like opatch or jvm.
