Hi Guys,
Prior to performing quarterly PSU patch, i will usually backup my ORACLE_HOME by using tar in Unix Platforms.
In case if there is any issue, i can just restore the binary using the backup tar.
For Windows, we can just backup the binary by copy to another place. However, technically can we use that copy for restore? Am asking because i'm wondering if the patches will change the registry as well therefore restoring the binary backup alone may not help.
I do understand that i rollback procedures for patches via opatch. Just curious on any documented way to restore windows oracle binary from backup for such scenario.
thanks
