EM 24ai: Applying Management Agent Release Update (RU) from the EM web interface

June 23, 2025 Leave a comment

Prerequisites

Before installing or uninstalling the RU, ensure that you meet the following requirements:

  1. Apply EM 24ai Release 1 Update 2 Patch 37629905 or it’s later Release Update version patch on the OMS before applying this RU.

    If you have not done this already, you can check my previous post.
  2. Deinstall this RU before deinstalling Enterprise Manager 24ai Release 1 Update 2 Patch 37629905 on OMS.

Installation

1. Login to the Enterprise Manager and navigate to Enterprise -> My Oracle Support -> Patches & Updates:

2. Enter the patch number (e.g. 37629915) in the “Software Library Patch Search” section and click Search:

3. Select the patch and click “Create Plan.” :

4. Enter the plan name and select the target agent:

5. Click the “Patches & Updates” hyperlink in the upper left corner:

6. Click on the plan name:

7. Click Next:

8. Click Next:

9. Deployment options:

In the Stage location, retain the default location (%emd_emstagedir%) available on the target machine, or edit the Stage Location to provide a new location for staging the Management Agent patches.
In the Oracle Home Credentials section, select Oracle Home Preferred Credentials if you have already set them earlier. You can otherwise click Override (like me):

9. Click “Select…” next to “Privileged Credentials,” then choose “New” in the pop-up window:

10. Click Validate Credentials:

11. Click Analyze:

If analysis fails, click Show Detailed Results:

To view the complete log, click on “Download Logs” in the upper right corner. Correct failed components. In my case, I did not have enough swap space; after increasing it, I re-analyzed and it became ready for deployment:

12. Click ‘Next’ and then ‘Deploy’. Select your desired time; I will choose immediately and click ‘Submit’.

13. The deployment status:

The deployment is in progress:

The deployment was successful:

14. You can check the applied patch using agentpatcher as well:

Set the oraclehome to proper agenthome and run lspatches:

$ export ORACLE_HOME=/u03/em24/agent/agent_24.1.0.0.0
$ /u03/em24/agent/agent_24.1.0.0.0/AgentPatcher/agentpatcher lspatches

EM 24ai: Configure EM agent manually after failure

June 9, 2025 Leave a comment

Problem:

While installing EM 24ai, everything was configured except for the agent which is the last step. It failed with the following vague error:

...
1. state_dir=/u03/em24/agent/agent_inst
2. agentBaseDir=/u03/em24/agent
3. oraHome=/u03/em24/agent/agent_24.1.0.0.0
INFO: oracle.sysman.top.agent:Agent Home is : {0}
SEVERE: oracle.sysman.top.agent:Agent configuration has failed
INFO: oracle.sysman.top.agent:AgentConfiguration:agent configuration finished with status = false
INFO: oracle.sysman.top.agent:AgentConfiguration:agent configuration finished with status = false
INFO: oracle.sysman.top.agent:The plug-in Agent Configuration Assistant has failed its perform method

Solution:

Make sure agent_inst directory is empty, otherwise rename the folder and recreate:

$ cd /u03/em24/agent
$ mv agent_inst agent_inst2
$ mkdir agent_inst; chmod 755 agent_inst

Make sure libnsl package is installed, otherwise install it using yum:

$ yum install libnsl

Reconfigure agent manually:

$ /u03/em24/middleware/oms_home/oui/bin/runConfig.sh ORACLE_HOME=/u03/em24/middleware/oms_home MODE=perform ACTION=configure COMPONENT_XML={encap_oms.1_0_0_0_0.xml}

Setting the invPtrLoc to /u03/em24/middleware/oms_home/oraInst.loc
...
Setting system property CUSTOM_INVENTORY to {0}
chain install is :true

Cloning of agent home completed successfully
Agent Configuration completed successfully
The following configuration scripts need to be executed as the "root" user. Root script to run : /u03/em24/agent/agent_24.1.0.0.0/root.sh

perform - mode finished for action: configure

Run root.sh script that is requested in the output of the above command: 

# /u03/em24/agent/agent_24.1.0.0.0/root.sh

It worked for me and I hope it will work for you as well. The solution was found after a lot of digging, and there might be another solution too.
