Fellow DBAs, oracle 11.1.0.7 on RHEL4 single instance database, with 1 Physical standby ( max avialability & FastStart Failover) and 1 logical standby all running the same version. We are having an issue with logical standby when ever there is a primary flips to Physical standby. We are getting ORA-16806 – supplemental logging is not turned on. My question, does logical standby survive through primary failovers? If yes then is there any thing I have to do so that I do not get this error? thanks Deen
