How to resize your redo logs.

1. Select which log file (group) you want to resize.
2. Make sure that it has been archived and not active.
*note if the redo log file is active simply do a log switch until it is no longer active.
3. drop the log file (group).
4. Go to the O.S. and drop the physical file(s)associated with the group you just dropped.
5. Recreate the log file with the new size.


Also, for the newbies.. DO NOT DROP THEM ALL AT THE SAME TIME DO THEM INDIVIDUALLY!
I dare say this but..It's really easy in OEM.
