Goal
12c Grid Infrastructure introduces software patch level and active patch level to ensure GI home has identical patches on all nodes. Unless the cluster is in rolling patch mode, a node won't be able to join the cluster if it has different patch level.
At the end of a patch application to GI home, the software patch level will be updated on each node. On the last node, the active patch level will be updated for the cluster. It's highly recommended to manually take an OCR backup with "ocrconfig -manualbackup" command before and after applying a patch.
The patch level is stored in OCR, special consideration is needed when restoring an OCR backup.
