How to Apply Grid Infrastructure Patches Before Upgrading or Installing Cluster

While upgrading GI from 12.1.0.2 to GI 12.2.0.1, in order to minimize the downtime and reduce the impact on PROD environment, PSU or one off patches can be applied onto 12.2.0.1 image before setting up 12.2.0.1 GI.

Here is the example of applying GI JAN 2018 Release Update ( RU) 12.2.0.1.180116.

1)As the owner of GI HOME, unzip the gold image under new 12.2.0.1 GI HOME.

$cd  /u00/app/12.2.0.1 
$unzip <SW-LOCATION>/linuxx64_12201_grid_home.zip -d ./

2)As the owner of GI HOME, unzip GI JAN 2018 RU patch.

$cd  /tmp
$unzip <SW-LOCATION>/p27100009_122010_GI_RU_180116_Linux-x86-64.zip

3) Apply the patch by using option “-applyPSU”, and confirm the successful patching.

$cd /u01/app/12.2.0.1/grid
$ ./gridSetup.sh -silent -applyPSU /tmp/27100009/
Preparing the home to patch...
Applying the patch /tmp/27100009/...
Successfully applied the patch.
The log can be found at: /u01/app/oraInventory/logs/
GridSetupActions2018-02-01_03-05-11PM/installerPatchActions_2018-02-
01_03-05-11PM.log

Check the log to confirm the patches are applied successfully.

$cd /u01/app/12.2.0.1/grid/cfgtoollogs/opatch
$ grep -i "successfully applied" *

opatch2018-02-01_15-07-49PM_1.log:[Feb 1, 2018 3:07:54 PM] [INFO] Patch 26839277 successfully applied.

Or apply the patch one by one by using “-applyOneOffs” option:

$cd /u01/app/12.2.0.1/grid
$./gridSetup.sh -silent -applyOneOffs /tmp/27100009/27144050
$./gridSetup.sh -silent -applyOneOffs /tmp/27100009/27128906
$./gridSetup.sh -silent -applyOneOffs /tmp/27100009/27335416 
$./gridSetup.sh -silent -applyOneOffs /tmp/27100009/27105253 
$./gridSetup.sh -silent -applyOneOffs /tmp/27100009/26839277

4) After the GI upgraded , we can confirm the patches are applied and listed successfully:

$ opatch lspatches
