Does Enterprise Manager Support RAC One Node?
Yes, you can use Enterprise Manager DB Console to manage RAC One Node databases. Note that in 11.2.0.1, when you run raconeinit, the instance name is changed. you should either configure EM DB Console after running raconeinit, and after every instance relocation (Omotion) or failover, the EM DB Console will need to be reconfigured to see the new instance on the new node. This can be done using emca and is the same as with adding any new DB to the configuration. In the future, 11.2.0.2, EM will support RAC One Node database out of the box. so EM will be able to detect when the instance is migrated or failed over to another node.
