12c Patching Resume with Nonrolling Option While Analyze - JSON Magic

I was engaged in an interesting Oracle 12c patching today.  Patch applicability was checked by using:

"$GRID_HOME/OPatch/opatchauto apply /u01/app/oracle/software/24436306 -analyze"

and it failed because its a non-rolling patch:

"OPATCHAUTO-72085: Cannot execute in rolling mode, as execution mode is set to non-rolling for patch ID 24315824.
OPATCHAUTO-72085: Execute in non-rolling mode by adding option '-nonrolling' during execution. e.g. /OPatch/opatchauto apply -nonrolling
After fixing the cause of failure Run opatchauto resume with session id "F7ET "]"

So now I wanted to analyze the patch with non-rolling option.

$GRID_HOME/OPatch/opatchauto apply /u01/app/oracle/software/24436306 -analyze -nonrolling

Time taken to complete the session 0 minute, 1 second

opatchauto bootstrapping failed with error code 1.


In 12c, we have the patching sessions with their configuration in JSON files.

So go to directory $grid_home/OPatch/auto/dbsessioninfo/

and find the JSON file with session id F7ET, which was given in above error.

Edit this file and change the flag of non-rolling to TRUE.

      "key" : "nonrolling",
      "value" : "false"

Change above to :

      "key" : "nonrolling",
      "value" : "true"

Save the file and run the opatchauto analyze again with resume session

$GRID_HOME/OPatch/opatchauto resume -session F7ET

and it works!!!

Happy Patching!!!
