This is the following of my previous post about the frequent redo log switching. My current redo log size is 50 MB each.You noticed that those switchings only occurred in the early morning around 8 am when users report to work.After that hour, the switching is back to normal, every 2 hours.I am pretty sure that our user just log into BAAN system ( which is linked to Oracle), not run any process on Oracle yet.That puzzled me, what caused the oracle to run so many redo log switchings, while during the real business hour (9 am ~ 5 pm), it does not.Some user (in oracle forum) said that as long as there is no "CHECKPOINT NOT COMPLETE" in alert log, I should not worry; or to increase the FAST_START_MTTR_TARGET.
