25.3 Manual Management Agent Patching

Manual patching is a patching mechanism that requires you to follow step-by-step instructions to patch a Management Agent manually. This mechanism of patching requires you to ensure certain prerequisites, manually validate the patch for applicability and conflicts, and can be used to patch only a single Management Agent at a time.

Note:

Oracle recommends that you use the automated patching mechanism as it not only saves time and effort in mass-deploying patches, but also reduces human intervention, thereby minimizing the errors involved during the patching process.

To patch a Management Agent target manually, perform the following steps:

Log into My Oracle Support (https://support.oracle.com).
Note:
Ensure that you check the Patch Recommendation section to view the patches that are recommended for your environment.
On the My Oracle Support home page, click Patches and Updates.
Enter the required patch number in the Patch Search section, then click Search.
Select the patch, and from the context menu that appears, select Download.
Extract the patch zip file and follow the instructions available in Readme.html or Readme.txt to install the patch.
Note:
In Cloud Control, separate Management Agent patches exist for core components of Management Agents and Management Agent plug-ins. Ensure that you navigate to the correct directory location under <installation_base_directory> while manually patching a Management Agent core component or a Management Agent plug-in. For example, to patch a Management Agent core component manually, you must navigate to <installation_base_directory>/core/, and to patch a Management Agent plug-in, you must navigate to <installation_base_directory>/plugins. The following is the structure of the Management Agent installation base directory:
```
<installation_base_directory>
    |_____core
         |_____12.1.0.4.0
    |_____plugins
    |_____plugins.txt
    |_____plugins.txt.status
    |_____agent_inst
    |_____sbin
    |_____agentimage.properties
```
