Goal
When applying interim patches or Security Patch Update (SPU) (formerly Critical Patch Update (CPU)) patches, OPatch takes a big amount of disk space under $ORACLE_HOME/.patch_storage to store a backup of the affected libraries and modules that have been updated.This may increase the used capacity by 5G-10G in some cases. It even could happen that a disk becomes full in the middle of the patching process.
Regarding this topic, the following questions will be answered in this article:
1. ) If the filesystem gets full in the middle of applying a patch, what is the process to recover?
2. ) Can any of the space be reclaimed from $ORACLE_HOME/.patch_storage?
3. ) Usage of 'opatch util cleanup' to reclaim space from $ORACLE_HOME/.patch_storage
4. ) In preparation for patching systems, is there any way to predict the amount of space that will be required in $ORACLE_HOME/.patch_storage?
