Yesterday I wanted to apply a brand new patch to customer’s Enterprise Manager 13cR2 OMS running on Linux. First I updated the OMSPatcher as described here: How to upgrade the 13.1 Cloud Control OMSPatcher to latest version of OMSPatcher (Doc ID 2135028.1). This update was easy. Download, transfer, unzip and copy the OMSPatcher files to the Enterprise Manager ORACLE_HOME directory.
Then the patch apply results in an error. OMSPatcher is based on OPatch, he needs an update too.
We need a new OPatch Version
This was error message for patch apply with omspatcher when I executed the apply command.
[Dec 1, 2016 10:17:38 AM] Prerequisite check "CheckMinimumOPatchVersion" failed.
The details are:
The OPatch being used has version 13.8.0.0.0 while the following patch(es) require higher versions:
Patch 24914115 requires OPatch version 13.9.1.0.0.
Please download latest OPatch from My Oracle Support.
My actual EM13cR2 OPatch version was 13.8.0.0.0.
oracle@kestenholz:/u00/app/oracle/product/em13cr2/OPatch/ [oms13cr2] ./opatch version OPatch Version: 13.8.0.0.0 OPatch succeeded.
Get the new Version
In My Oracle Support I found the newest version of OPatch, Download.
Transfer and extract
The next step was to extract and to transfer the package to the target server.And then I was wondering that not like in versions before an OPatch directory was created, now there is a JAR file inside the package. Copy & Paste of an OPatch directory is no more possible anymore.

Installation Routine – README.txt
Let’s take a look in the README.txt – there is an installation manual.
oracle@kestenholz:/u00/app/oracle/stage/OPatch/6880880/ [oms13cr2] cat README.txt
Installation
----------------------------------
- Backup your <ORACLE_HOME>
- Unzip this patch into your staging directory PATCH_HOME
- Install the software via:
java -jar <PATCH_HOME>/6880880/opatch_generic.jar -silent oracle_home=ORACLE_HOME
- To validate the installation:
cd <ORACLE_HOME>/OPatch
opatch version
opatch lspatches
Installation – 1st run – where is my JDK ?
oracle@kestenholz:~/ [oms13cr2] java -jar /u00/app/oracle/stage/6880880/opatch_generic.jar -silent oracle_home=/u00/app/oracle/roduct/em13cr2 Launcher log file is /tmp/OraInstall2016-12-02_10-00-10AM/launcher2016-12-02_10-00-10AM.log.

Installation – 2nd run – JRE is not good enough
I tried to use the existing JDK from my Oracle 12.1 installation

Installation – 3rd run – JDK 1.7 rocks
Now I have downloaded and configured JDK 1.7. Another try, and now it works. Here is a short summary of the output. In the background now the Oracle Universal Installer is started.
Thanks to Gokhan Atil – http://www.gokhanatil.com – for the second possibility, you can use the JDK from the OMS too.

Job done
Now the version was ok, the patch could be applied.
oracle@kestenholz:/u00/app/oracle/product/em13cr2/OPatch/ [oms13cr2] ./opatch version OPatch Version: 13.9.1.0.0 OPatch succeeded.
Additional Information: If the installer does not find your inventory location (was happened to me on an AIX system), just execute the install command with the parameter -invPtrLoc.
java -jar /u00/app/oracle/stage/6880880/opatch_generic.jar -silent oracle_home=/u00/app/oracle/product/oms13cr2 -invPtrLoc /etc/oraInst.loc
The OMSPatcher can be updated like before, but the other important component in the patch process OPatch has has to be installed. From my point of view this is a step back, I don’t know what was the idea behind to change it. Now you have to be sure, that there is an existing JDK 1.7 available on your system. This means that applying a patch on the express way is not possible anymore, you have to fulfill the prerequisite before you have an actual OPatch. And at the moment, there is no other documentation than the README.txt available, the hint with the inventory parameter came from My Oracle Support after I opened a SR.
Say good-bye to Unzip, Copy & Paste.
