Hi All,

We have oracle data guard with 1 phy. stdby. configured in max. availability mode.Fast start failover is enabled .

Issue - On issuing DGMGRL> failover to <stdby_db>;

It failed with -> "Performing failover NOW, please wait...
Error: ORA-16798: unable to complete recovery during failover

Failed.
Unable to failover
"

On the alert.log it reported - > "CLOSE: fail to kill all active sessions
CLOSE: Error 1093 during database close
ORA-1093 signalled during: ALTER DATABASE RECOVER MANAGED STANDBY DATABASE FINISH FORCE...
Wed Sep 22 19:14:04 2010
Failover failed with ORA-16798."

The databases were in synchronized state and were applying logs before failover. Still failover failed does anyone know why this might have happened?

Howdy, Stranger!
