Step by Step OPatch upgrade in Oracle

Step by Step Utility OPatch” Upgrade along with Latest Download Binary in Oracle

I was applying the October patch on my 12.2.0.1 Oracle home and it got failed with the below error in prechecks due to the version of utility “OPatch” didn’t meet to minimum required version as per Oracle recommendations. So always recommended going through read me a document of specific patch ID before patch applies to eliminate any roadblock in activities.

Below is the error while performing conflict for patch id
31741641 October 2020 patch.

Utility “OPatch” Upgrade Demonstration

Below are step-by-step demonstration on utilityOPatch upgrade and the minimum version is require 12.2.0.1.21 so we will upgrade here the most latest version of utility OPatch.


Step-1:
  In this step, we will download most latest “OPatch” version 6880880 from My Oracle Support. While downloading “OPatch” make sure to select the correct version & OS platform then click on the download button. Below is a sample screenshot.


Step-2:
Move the downloaded patch binary to the desired server where it’s required to upgrade “OPatch”  version.

[oracle@DBsGuru-lab1 ~]$ cd /oradata/12.2.0.1_patch_oct2020

[oracle@DBsGuru-lab1 ~]$ ls 
p6880880_122010_Linux-x86-64.zip 


Step-3: 
We will take a backup of the existing utility “OPatch” as a rollback plan in case of any misshapen during the upgrade.

[oracle@DBsGuru-lab1 ~]$ . oraenv
ORACLE_SID = [labdb02] ? labdb01
The Oracle base remains unchanged with value /u01/app/oracle

[oracle@DBsGuru-lab1 ~]$ cp -R $ORACLE_HOME/OPatch -R $ORACLE_HOME/OPatch_01Nov20.bkp

[oracle@DBsGuru-lab1 ~]$ ls -ld $ORACLE_HOME/OPatch*
drwxrwxr-x 10 oracle oinstall 4096 Sep 25  2016 /u01/app/oracle/product/12.1.0/db_1/OPatch
drwxr-xr-x 10 oracle oinstall 4096 Nov  1 13:59 /u01/app/oracle/product/12.1.0/db_1/OPatch_01Nov20.bkp

OR alternatively, follow the below command.

[oracle@DBsGuru-lab1 ~]$ cd $ORACLE_HOME

[oracle@DBsGuru-lab1 db_1]$ pwd
/u01/app/oracle/product/12.2.0.1/db_1

[oracle@DBsGuru-lab1-lab1 db_1]$ cp -R OPatch -R OPatch_01Nov20.bkp

[oracle@DBsGuru-lab1 db_1]$ ls -ld OPatch*
drwxrwxr-x 10 oracle oinstall 4096 Sep 25  2016 OPatch
drwxr-xr-x 11 oracle oinstall 4096 Nov  1 14:04 OPatch_01Nov20.bkp


Step-4:
In this step, we will upgrade utility “OPatch” followed by the below commands. 

[oracle@DBsGuru-lab1 ~]$ . oraenv
ORACLE_SID = [labdb02] ? labdb01
The Oracle base remains unchanged with value /u01/app/oracle

[oracle@DBsGuru-lab1 ~]$ cd /oradata/12.2.0.1_patch_oct2020

[oracle@DBsGuru-lab1 12.2.0.1_patch_oct2020]$ unzip p6880880_122010_Linux-x86-64.zip -d /u01/app/oracle/product/12.2.0.1/db_1/

OR alternatively, follow the below command.

[oracle@DBsGuru-lab1 12.2.0.1_patch_oct2020]$ unzip p6880880_122010_Linux-x86-64.zip -d $ORACLE_HOME

NOTE: In the above command line number 14, we used option “A(ll)” while unzipping since we have taken a backup of utility “OPatch” in the same location in Step-3.


Step-5:
Now we are in the final stage to validate the version of utility “OPatch” after an upgrade and we are all set to perform applying the patches.

[oracle@DBsGuru-lab1 ~]$ . oraenv
ORACLE_SID = [labdb02] ? labdb01
The Oracle base remains unchanged with value /u01/app/oracle

[oracle@DBsGuru-lab1 ~]$ export PATH=$ORACLE_HOME/OPatch:$PATH

[oracle@DBsGuru-lab1 ~]$ opatch version
OPatch Version: 12.2.0.1.21

[oracle@DBsGuru-lab1 ~]$ cat  $ORACLE_HOME/OPatch/version.txt
OPATCH_VERSION:12.2.0.1.21

OR alternatively, follow the below command.

[oracle@DBsGuru-lab1 ~]$ cd $ORACLE_HOME/OPatch

[oracle@DBsGuru-lab1 OPatch ~]$ ./opatch version
OPatch Version: 12.2.0.1.21

[oracle@DBsGuru-lab1 OPatch ~]$ cat version.txt
OPATCH_VERSION:12.2.0.1.21
