Oracle OEM Cloud Control 12.1.0.4 – agent upgrade & patch

The new Oracle OEM Cloud Control 12.1.0.4 release migration makes it necessary for the DBA to migrate the old agent version to 12.1.0.4. If your infrastructure has a huge number of agents and if you want to apply the agent patches to the upgraded agents, this might be a very time-consuming job. However, there is a way to realize the operation in just one shot.

In my example, we have an agent in version 12.1.0.3:

oracle@vmtestfusion01:/u00/app/oracle/agent12c/core/12.1.0.3.0/OPatch/ [agent12c] ./opatch lsinventory

OPatch succeeded.

In the OMS environment, we have to download and copy the agent-side patches to $OMS_HOME/install/oneoffs/12.1.0.4.0/Generic.

In my example, I downloaded the 19002534 EM DB plugin bundle patch 12.1.0.6.1 (agent side):

oracle@vmtestoraem12c:/u01/app/oracle/MiddleWare_12cR4/oms/install/oneoffs/12.1.0.4.0/Generic/ [oms12c] ls

p19002534_121060_Generic.zip

The agent upgrade procedure will use this directory to apply the patch.

Let’s upgrade the agent from 12.1.0.3 to 12.1.0.4 by using the Cloud Control console:

ag1

Select the agent to be upgraded:

ag2_copy

The new job screen lists the different steps:

ag3_copy

In the log file we can visualize the patch:

By checking the agent inventory, we verify the new upgraded agent has received the EM DB PLUGIN BUNDLE PATCH 12.1.0.6.1:

This feature is very useful for massive agent upgrades, because the agent is upgraded and, in the same operation, the bundle patch is applied. You are also able to use the patch plan to apply bundle patches to multiple agents in one operation.
