Minimal Downtime Grid Infrastructure Out of Place Patching

Looks like OOP is back again; however, I have not had the opportunity to test.

When you test, it’s important to test rollback as well.

GRID Out Of Place (OOP) Rollback Disaster

Steps for Minimal Downtime Grid Infrastructure Out of Place ( OOP ) Patching using gridSetup.sh (Doc ID 2662762.1)
May 13, 2020
Oracle Database – Enterprise Edition – Version 19.6.0.0.0 and later
This is applicable only for cluster environment,not the SIHA(Oracle Restart)

In general, the following steps are involved:

1) Installing and Patching the Grid infrastructure (software only)

/u01/app/19.7.0.0/grid/gridSetup.sh -ApplyRU 3089972
Chose the option “Install Software only” and select all the nodes.

2) Switching the Grid Infrastructure Home

Run the gridSetup.sh from the target home

/u01/app/19.7.0.0/grid/gridSetup.sh -SwitchGridhome

It will launch the GUI (you could run it in silent as well with a response file)

During this phase, you can select the automated root.sh option if you wanted. Otherwise it will prompt the root.sh.

  1. Have you tried this with a SIHA home? As I am looking for a solution that would work with both RAC and non-RAC environments, I gave it an attempt (despite the warning that it is only for RAC/CRS). As expected it failed.
    Error is below:
    [FATAL] [INS-45101] Clusterware is not running on the local node.
    ACTION: Ensure that the Clusterware is configured and is running on local node before proceeding.

    Reason I post this this that I would like to be able to use the “gold image” approach for patching GI without Fleet patching. Curious if you have any other thoughts/ideas.

    • Not sure if this will work.
      tar GI, untar GI to new location, New GI gridSetup.sh -ApplyRU patch -silent (no response file)
      Thought is that New GI will get patched only.
