Martijn, Interesting.. I wanted to crosscheck with you, I believe you have updated 1) "FastStartFailoverTarget" value for both primary and standby database & 2) enabled FSFO from broker values before you start the observer. Correct? Also can you get these details DGMGRL> show database verbose 'aosb2_wurlali' what is the Oracle verion of the client?(observer) Also Apart from observer, do you see any informational/errors from broker log files(just in case) ? Thanks, Nassyam Basha.
