How to reload Grid Agent with a new OMS installation

Applies to:

Enterprise Manager Grid Control - Version: 10.1.0.2 to 10.1.0.3
This problem can occur on any platform.

 Symptoms

Oracle Management Agent, version 10.1.0.2.0 (or 10.1.0.3.0), is not able to upload to Oracle Management Server.

emctl upload returns the error:

"OMS VERSION NOT CHECKED YET"

emctl status agent shows a backlog of files waiting to be uploaded and no data in the OMS Version field.

Cause

After a new OMS installation, Grid Agent still tries communicate with an OMS server during an old communication key file repoconn.ora which is located in $AGENT_HOME/sysman/config/server directory. It is necessary to syncronize this file with OMS server in order receive a permission to upload XML files through SSL connection.

Solution

To implement the solution, please execute the following steps:

1.      Go to $AGENT_HOME/sysman/config directory on Manager Server and find the path to the following URL:

oragrid:/oracle/oms10g/sysman/config>grep emdWalletSrcUrl emd.properties emdWalletSrcUrl=http://dbalinux:4890/em/wallets/emd

2.      Go to $AGENT_HOME\sysman\config directory on Agent Server. Replace emdWalletSrcUrlkey in emd.properties file with appropriate key you found in previous step.

3.      Request a new communication key from OMS by entering the following command on the Agent Server. Provide the right password to the manager server :

C:\oracle\products\ora_agent\agent10g\bin>emctl secure agent Oracle Enterprise Manager 10g Release 10.2.0.1.0. Copyright © 1996, 2006 Oracle Corporation.  All rights reserved. Enter Agent Registration password : ********    Response From Agent: running Error connecting to https://ayjalms2kmish.tapash2k.even:3872/emd/main/ Error connecting to https://ayjalms2kmish.tapash2k.even:3872/emd/main/ Agent successfully stopped…   Done.

4.      Start agent, in the case it is not running, issue an agent clearstate and force an upload to the OMS:

C:\oracle\products\ora_agent\agent10g\bin>emctl start agent Oracle Enterprise Manager 10g Release 10.2.0.1.0. Copyright © 1996, 2006 Oracle Corporation.  All rights reserved. The Oracleagent10gAgent service is starting……….. The Oracleagent10gAgent service was started successfully. C:\oracle\products\ora_agent\agent10g\bin>emctl clearstate agent Oracle Enterprise Manager 10g Release 10.2.0.1.0. Copyright © 1996, 2006 Oracle Corporation.  All rights reserved.

5.      If agent still does not upload files then make the following on Manager Server:

oragrid@dbalinux:/oracle>emctl secure oms -sysman_pwd ******* Oracle Enterprise Manager 10g Release 10.2.0.1.0 Copyright © 1996, 2005 Oracle Corporation.  All rights reserved.
