There is easier way of  pointing agent to new oms in 11g.

Go the $AGENT_HOME/bin and execute just one command,

$ ./emctl switchOMS https://oms_hostname:1159/em/upload
Oracle Enterprise Manager 11g Release 1 Grid Control 11.1.0.1.0

SwitchOMS succeeded.

If you have agent registration passwd enabled, do the below steps,

$./emctl stop agent

$./emctl secure agent ‘pwd’

$./emctl start agent

Before 11g, you will have to follow steps given metalink#413228.1

In case if you have lost agent registration pwd and want to create new one. Go to setup=> registration pwd and remove the existing one.

then in the OMS server execute below command,

/emctl secure setpwd

Enter Enterprise Manager Root Password :
Enter New Agent Registration Password :
Registration Password added successfully.

root password above is sysman password

It’s specific to AIX environment. While doing oms installation during the agent configuration stage it failed. Even a fresh installation of agent in oms host will fail with similar error. You will not be able to stop or start the agent.

It’s a aix bug, metalink#1298284.1 talks about it. There is a workaround provided in that note.

Workaround provided by Oracle:

1. export $ORACLE_HOME=<agent home>/sysman/lib
2. cd <agent home>/sysman/lib
3. backup env_emagent.mk
4. Modify env_emagent.mk:
   Search “LIB_JVM_LINK =”
   Remove the “-blazy” option from LIB_JVM_LINK definition
   Save the file
5. /usr/sbin/slibclean

5.1. export OBJECT_MODE=32 ==> Pls note this step is missing in the oracle document

6. make -f ins_emagent.mk agent
