Issues & Fixes while upgrading GI from 12.1.0.2.0 to 19.14.0.0.0
RAC environment.
Source GI version: 12.1.0.2.0
Target GI Version: 19.14.0.0.0
Our Plan is to upgrade GI in rolling fashion, that’s why don’t want to touch the second node until first node is successfully completed..
1) As part of prechecks we ran runcluvfy and found below output.
Node1 +ASM1 $ grep -i fail prechec_ouput.txt
Node1 missing 28553832 failed
Node2 missing 28553832 failed
Then decided to apply bundle patch 28553832 on 12.1.0.2.0 GI as a pre upgrade patch.
2) Downloaded and verified pre-checks , found conflicts and rollbacked some patches. and then applied bundle patch 28553832 on 12c
(did not touch the second node)
Then cluster services did not come up
3) Rolled back bundle patch 28553832.
Tried to start cluster services but did not work .
Tried to restore Grid binaries on 1st node from backup but it did not work
Later we had to delete node1 and then added the node1 in the cluster successfully. Started cluster services.
4) After that applied grid PSU patch(Jan 2022) 33575274, and then did not find any missing patch info in the runcluvfy utility’s o/p.
5) Next upgraded grid to 19.3.0.0.0 version ,used dry run option to apply 19.12 and then applied 19.14 patch.
In summary , while upgrading GI ,Latest GI PSU patch(Jan 2022) 33575274 (on 12.1.0.2.0) is sufficient
for applying missing patches in the runcluvfy o/p.
