can opatch 12 be used in a 11g oracle database home?
The readme for Patch for Bug# 23580463 for Linux-x86-64 platform states:
"Note:
When patching the GI Home, a shared location on ACFS only needs to be unmounted on the node where the GI Home is being patched.
The new opatch utility should be updated in all the Oracle RAC database homes and the GI home that are being patched. To update Opatch, use the following instructions."
Does this include Oracle 11g database homes?
