The Patch Deployment feature in EM12c can greatly help in automating the rolling out of patches when we have to deploy the patch on a large number of targets – this significantly reduces both the time and complexity involved in the process.
Let us look at an example of deploying the JAN 2015 PSU patch using EM12c.
We first need to upload the JAN 2015 PSU patch 19769480 as well as the opatch version 220.127.116.11.6 to the EM12c Software Library – as we are operating in Offline Patching mode.
Note that we have to upload the Patch Metadata file as well along with the patch
Click on 19769480 link in the Patch Name column
We will add the patch to a New Patch Plan
We can deploy the PSU patch on all available hosts with 18.104.22.168 Oracle databases – in this example we are deploying the PSU to just a single host.
After the patch plan has been created we edit the patch plan via the Patches & Updates menu
The Patch deployment can be In Place or Out of Place. In this case we will be applying the PSU patch to the existing Oracle Home. Provide the required Normal and Privileged Credentials and validate the same.
If we select the relevant 22.214.171.124 Oracle Home in the Targets menu, we can see under the Patches Applied tab that patch 19769480 has been successfully applied and we also can see the various bugs which have been fixed by this PSU patch.
