Oracle RAC 12c - Simple steps to manually rollback a PSU Patch from a node

I will use the latest October 2016 PSU patch as a test case for this post...

Environment:
Server/OS - HP UX Itanium (11.31)
2 Node RAC - no ACFS, no shared homes, ASM is used

Method of applying patches -
Fully Manual
Non-Rolling
Why? 
 - better control,
 - non-availability of bash in  our HP UX servers which is required to run opatchauto

What do should know about the October PSU patch for RAC?
OCW PSU patch number  -- 23854735
DB PSU patch number      -- 24006101

Below are very very simple steps to rollback the patches in your environment:

DB HOME:
opatch nrollback -local -id 24006101 -oh $ORACLE_HOME
cd /u01/software/psuoct2016/12cGI/24412235/23854735/custom/scripts
./prepatch.sh
opatch nrollback -local -id 23854735 -oh $ORACLE_HOME
./postpatch.sh

GRID HOME:
$GRID_HOME/crs/install/rootcrs.pl -prepatch [-nonrolling]
opatch nrollback -local -id 24006101 -oh $GRID_HOME
opatch nrollback -local -id 23854735 -oh $GRID_HOME
$GRID_HOME/crs/install/rootcrs.pl -postpatch  [-nonrolling]

Use -nonrolling only if you have patched using the nonrolling mode.

Hope this helps!
Cheers
