determine if DB is in a DataGuard config

Is there a value that can be queried to absolutely determine if a database is in a DataGuard config?

I see a few things in v$database that would *IF* it were not the primary, OR if it were the primary *AND* managed by the DG Broker. But what if it were the primary and NOT manged by the DG Broker? Received on Sat Dec 30 2006 - 14:29:13 CST
