Oracle 11g Grid | Installing Grid Agent using "agentDownload" method

To get AGENT working with OMS Grid , you will need ports 3872,4889/4900 accessible between machines.

If you wish to delete host from OMS Grid then delete Targets/Host at grid control first. Now use following SQL script to make sure it’s not exisitng at OMS repository . It will save you lot of frustration.

SQL> select distinct target_name,target_type  from SYSMAN.MGMT$TARGET where target_name like ‘AGENT_HOST%’;
TARGET_NAME
——————————————————————————–
AGENT_HOST:3872
oracle_emd

If Agent is listed , use following SQL to remove it from OMS repository.

SQL> exec sysman.mgmt_admin.cleanup_agent(‘AGENT_HOST:3872′);
PL/SQL procedure successfully completed.

SQL> select distinct target_name,target_type  from SYSMAN.MGMT$TARGET where target_name like ‘AGENT_HOST%’;
no rows selected

Login at OMS and locate  “agentDownload” shell script

For my RHEL -11g OMS setup it’s under “$OMS_HOME/sysman/agent_download/11.1.0.1.0/linux_x64″

Copy this script at Destination AGENT_HOST location

I used “scp agentDownload.linux_x64 oracle@AGENT_HOST:/opt/app/oracle/product”

Now go to Agent host & run  script

[oracle@agent_host]$ ./agentDownload.linux_x64
