Hi elintrend

did you notice something in your log file.see what it says here

Automatic datafile offline due to write error on
file 39: H:\ORCLBERP\ROLLBACK\RBS3BERP.ORA

oracle has taken your data-file offline as the oracle process was not able to write to this file due to some reason.now we have to investigate further i think for some reason (it is my guess though) oracle dbwr or lgwr was not able to write.now check the tarce files this will be in the loaction where you have set the init parameter back_ground_dump_test.there you can find more info and take remedial action.
