How to change Grid Control Repository Database from Single Instance to RAC

1-Run command below using your RAC information in all OMS nodes:

emctl config oms -store_repos_details -repos_conndesc '(DESCRIPTION=
(ADDRESS_LIST=(FAILOVER=ON)
(ADDRESS=(PROTOCOL=TCP)(HOST=host01-vip)(PORT=1523))
(ADDRESS=(PROTOCOL=TCP)(HOST=host02-vip)(PORT=1523)))
(CONNECT_DATA=(SERVICE_NAME=SERVDB)))' -repos_user sysman -repos_pwd secret


2-Check new configuration using this command below:
emctl config oms -list_repos_details

3-Restart OMS
