EM13c- Applying System Patches with the OMS Patcher

The OMS Patcher is a newer patching mechanism for the OMS specifically, (I know, the name kind of gave it away…)  Although there are a number of similarities to Oracle’s infamous OPatch, I’ve been spending a lot of time on OTN’s support forums and via email, assisting folks as they apply the first system patch to 13.1.0.0.0.  Admit it, we know how much you like patching…

The patch we’ll be working with is the following:

./emctl stop oms

$ORACLE_HOME should be set to OMS_HOME and set omspatcher to the OMSPATCHER :

export omspatcher=$OMS_HOME/OMSPATCHER/omspatcher
export ORACLE_HOME=/u01/app/oracle/13c

$ omspatcher apply -analyze  -property_file <location of property file>

I’d recommend running the following instead, which is a simplified command and will result in success if you’re set up your environment:

omspatcher apply <path to your patch location>/22920724 -analyze

If this returns with a successful test of your patch, then simply remove the “-analyze” from the command and it will then apply the patch:

omspatcher apply <path to your patch location>/22920724

You’ll be asked a couple of questions, so be ready with the information, including verifying that you can log into your Weblogic console.

Verify that the Weblogic domain URL and username is correct or type in the correct one, enter the weblogic password
Choose to apply the patch by clicking “Y”
Patch should proceed.
The output of the patch will look like the following:

OMSPatcher log file: /u01/app/oracle/13c/cfgtoollogs/omspatcher/22920724/omspatcher_2016-04-29_15-42-56PM_deploy.log

Please enter OMS weblogic admin server URL(t3s://adc00osp.us.oracle.com:7102):>
Please enter OMS weblogic admin server username(weblogic):>
Please enter OMS weblogic admin server password:>

OMSPatcher succeeded.

Note the sub-patch information.  It’s important to know that this is contained in the log, for it you needed to rollback a system patch, it must be done via each sub-patch using the Identifier listed here.

If you attempted to rollback the system patch, using the system patch identifier, you’d receive an error:

$ 01/app/oracle/13c/OMSPatcher/omspatcher rollback -id 22920724 -analyze <

"22920724" is a system patch ID. OMSPatcher does not support roll back with system patch ID.

OMSRollbackSession failed: "22920724" is a system patch ID. OMSPatcher does not support roll back with system patch ID.

 
Once the system patch has completed successfully, you’ll need to add the agent patch and best practice is to use a patch plan and apply it to one agent, make it the gold agent current image and then apply that to all your agents that are subscribed to it.  If you need more information on how to use Gold Agent Images, just read up on it in this post.
