OEM HA.
interested what people have deployed for High Availabilty for OMS.
We have an existing system which is located on two sites.
Site 1 has an a 2 node Oracle RAC database 11g and a server running OEM 11. Site 2 is identical and one acts as the primary and the other a dataguard DR.
The targets are created on both OEMS and we wrote scripts which switch the OEM agents to reference either the primary or dr OEM server. This works great for monitoring the estate. It does mean we lose some OEM history, but that's less important than being able to monitor the system.
