Patching is fun, isn’t it? And you may have heard already that the April 2018 patch bundles got released on April 17, 2018. And I thought I share a little bit of fun with you with a quick guide to patching my databases with the April 2018 PSU, BP and RU. For this exercise I use our Hands-On Lab with Oracle 11.2.0.4, Oracle 12.1.0.2 and Oracle 12.2.0.1 installed.

Prerequisites for patching my databases with the April 2018 PSU, BP and RU

First of all, in my VBox environment, I shutdown the databases for each release before patching them – and the central listener I use from within the Oracle 12.2.0.1 environment:

. cdb2
lsnrctl stop

In addition I will update OPatch in my 12.2 home and use this version for all 12c patch activities on the system. Please download the newest OPatch version 12.2.0.1.13 via patch 6880880 from MyOracle Support. Choose “12.2.0.1.0” in the drop-down list.

Patching my databases with the April 2018 PSU, BP and RU

Download OPatch 12.2.0.1.13 via MyOracle Support’s patch 6880880

The readme explains that the previous OPatch directory should be backed up and the new OPatch should be unpacked from the destination’s $ORACLE_HOME. I just heard from Kay Liesenfeld that “removing” the old directory may not be a good idea as he had trouble with the most recent GI patches then.

For the 11g database patching I will use my current OPatch version 11.2.0.3.12.

Furthermore, to identify the correct patches for each release I used MOS Note: 2353306.1 (Critical Patch Update (CPU) Program April 2018 Patch Availability Document (PAD)) as neither the Availability and Known Issues notes nor the Patch Download Assistant were updated two days after patch release. Go to bullet point 3.1.4 in MOS Note: 2353306.1 for Oracle Database Patch Availability. The other notes should be updated already when you read this blog post.

MOS Note: 2118136.2 – Assistant: Download Reference for Oracle Database/GI RU, BP, PSU was not updated by the time I wrote this blog post but is now.

Patching Oracle 11.2.0.4 with the April 2018 Patch Set Update

To patch my Oracle 11.2.0.4 databases I downloaded the Patch Set Update April 2018 as Bundle Patches in Oracle 11g are meant for Engineered Systems only:

First steps after changing into the patches directory are the checks:

cd /media/sf_TEMP/p27338049_112040_Linux-x86-64/27338049

$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph ./

Invoking prereq "checkconflictagainstohwithdetail"
Prereq "checkConflictAgainstOHWithDetail" passed.
OPatch succeeded.

Once the check is passed I can apply the patch – and of course, I must ensure to have shutdown my databases (UPGR and FTEX in the hands-on lab) first:

$ $ORACLE_HOME/OPatch/opatch apply

OPatch succeeded.

Finally I will have to execute catbundle.sql in all my 11.2.0.4 databases (UPGR and FTEX):

. upgr
cd $ORACLE_HOME/rdbms/admin
sqlplus / as sysdba

@catbundle.sql psu apply
exit

Done!

Patching Oracle 12.1.0.2 with the April 2018 Bundle Patch

For Oracle Database 12.1.0.2 I downloaded the Database Proactive Bundle Patch April 2018:

This patch bundle contains also Clusterware and Client patches – but the database patch is actually 27338029. According to the REAME.html I execute the conflict check – but in my case using the 12.2.0.1.12 OPatch previously installed:

/u01/app/oracle/product/12.2.0.1/OPatch/opatch  prereq CheckConflictAgainstOHWithDetail -phBaseDir /media/sf_TEMP/p27486326_121020_Linux-x86-64/27486326/27338029

Both checks succeed.Afterwards I initiate the space check:

/u01/app/oracle/product/12.2.0.1/OPatch/opatch  prereq CheckSystemSpace --phBaseDir /media/sf_TEMP/p27486326_121020_Linux-x86-64/27486326/27338029

Now I am applying the patch:

$ cd /media/sf_TEMP/p27486326_121020_Linux-x86-64/27486326/27338029
$ /u01/app/oracle/product/12.2.0.1/OPatch/opatch apply

OPatch succeeded.

In addition, datapatch needs to be executed now in both existing databases. Hence I’m starting up both databases, make sure the environment is set correctly (in the Lab: . db121 and . cdb1) and invoke datapatch:

$ /u01/app/oracle/product/12.2.0.1/OPatch/datapatch -verbose

Once I repeated this for the second database, patching for both 12.1.0.2 databases done as well.

Patching Oracle 12.2.0.1 with the April 2018 Update

As you may know already, there are no PSUs anymore in Oracle 12.2 and higher. You should patch with the Updates. Therefore I downloaded the Database April 2018 Update first. As my favorite note to download the correct patch just gets updated overnight I used MOS Note:2239820.1 – 12.2.0.1 Base Release – Availability and Known Issues to access the patch.

It contains the Database 12.2.0.1 Update April 2018 and the OJVM (which I won’t need). I unpack it to a share: /media/sf_TEMPand install it from there.

$ cd /media/sf_TEMP/p27726453_122010_Linux-x86-64/27726453/27674384
[CDB2] oracle@localhost:/media/sf_TEMP/p27726453_122010_Linux-x86-64/27726453/27674384

Then I call opatch for a conflict check:

$ /u01/app/oracle/product/12.2.0.1/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph ./
Oracle Interim Patch Installer version 12.2.0.1.13
Copyright (c) 2018, Oracle Corporation. All rights reserved.

Invoking prereq "checkconflictagainstohwithdetail"
Prereq "checkConflictAgainstOHWithDetail" passed.
OPatch succeeded.

And finally I apply the patch – I’m still in /media/sf_TEMP/p27726453_122010_Linux-x86-64/27726453/27674384, the directory where the Database 2018 Update is located in.

To finalize the patch application I need to start my database(s) and all PDBs:

SQL> startup
SQL> alter pluggable database all open;
SQL> exit

And then run datapatch:

$ /u01/app/oracle/product/12.2.0.1/OPatch/datapatch -verbose

That’s it.

At the end of the entire exercise I can restart my listener finally:
