The following occurrences will initiate FSF:įailover detects one of these failover situations through the Fast-Start Failover Observer (FSFO). a failover to the chosen standby target database will occur without DBA Simply put, FSF ensures that under theĪppropriate circumstances – some of which are mandatory,Īnd some of which are optionally-configured But it’s been enhanced significantly in Oracle 11 g to permit much finer-grained control over the conditions
