OPatch 12.2.0.1.37+ Introduces a New Feature to Delete Inactive Patches
OPatch 12.2.0.1.37+ Introduces a New Feature to Delete Inactive Patches in the ORACLE_HOME/.patch_storage Directory. I have in mind Doc ID 2942102.1. This document provides more information on the new features introduced on April 18, 2023 to list and delete inactive patches from ORACLE_HOME and .patch_storage.
This will improve binary patching performance improvement where more number of RUs are present in ORACLE_HOME and deletes space occupied by inactive patches in .patch_storage. For more information please check the above link with ID number.
