Database Software

I've set up a data guard environment consisting of the primary RAC 2node db and the physical standby RAC 2 node db, both on solaris and running oracle 10.2.0.2

Testing switchover using dgmgrl throws a problem

ora-16775:target standby database in broker operation has potential data loss.

This message appears to be bogus because a Verify Configuration confirmed the environment was working properly. I even did a log switch to confirm that the log was successfully applied to the standby and it got reapplied.

dataguard configuration shows its fine.but when doing a switchover it throws the above error.

i have removed the existing configuration and created a new one.
i have rebuilt the standby as well
but still throwing me the same error.
What is the cause of this problem and how do we fix it?

Thanks.
