JAN 2020 PSU patch for 12c(12.1.0.2) Grid Home

This document describes how to apply January 2020 PSU patches on Grid Home.

Below are the steps to complete PSU patch on GRID Home

1. Download PSU patch
2. Upgrade opatch to latest version
3. Analyze the patches (prepatch analysis)
4. Apply patches on Grid home
5. Post patch steps

1. Download PSU patches:

Use below url and download database and GI PSU.

https://www.oracle.com/security-alerts/cpujan2020.html

Note: In my case I have downloaded combo OJVM patches for Grid (30464119) and DB (30463684).


2. Upgrade opatch to latest version 

Take backup of OPatch folder which is under $GRID_HOME

Unzip the patch under $GRID_HOME

grid@server1 grid_home]$ unzip p6880880_180000_Linux-x86-64.zip


3. Analyze the patches (prepatch analysis)

SCP downloaded GI patch to server and unzip it. Verify the readme.txt file for any pre-requisite steps and analyze it for conflicts. Proceed for patching if no conflicts come. We have to raise an SR for merge patch if we get conflicts.

In my case, Non-shared oracle homes and grid homes across the 2 nodes. So we are applying the patch in rolling passion.  No ACFS file system available.

Note: We have to unmount ACFS file system if it is available in our environment before patching and mount it after apply the patch.

Run analyze command as root user and find conflicts if any. Output looks like below.
