Hi DBAs, Do you know if there a option (oracle parameter ) to do automatic log switching for shipping to standby server in 10gR2 (or 11gR2). For example , if the SLA defined as data loss less than 20 min , then we need to have somehow log switch event 20min ,even if the DB is idle (log switch once an hour) ?
