Home -> Community -> Mailing Lists -> Oracle-L -> RE: Resizing Log file
You can actually rebuild your control file to do your log files over again. I highly don't recommend it as it is technically doing alot more than you are trying to accomplish. But it technically safe and sound. Oracle frowns on rebuilding control files and uses at last case scenario, but it is a harmless procedure if done correctly. But as Mike mention about the reset logs, you need to get a backup immediately to keep recoverability after the control file rebuild.
There is no need to bring down the database to rebuild the sizes of the redo logs, control rebuild forces you to take the db down and does alot more than just size the logs. As everyone mentioned, add new ones and drop old ones then spin them is the supported and most direct method.

Hi,
I've never seen anyone use CREATE CONTROLFILE to resize redo logs and I
think
that I probably never will.
The only advantage I can think of is that you can reuse your original group
numbers though it might be helpful if you are REALLY tight on disk space.
The disadvantages are that you need to close your database, take a backup
and
you lose the ability to roll forward beyond the RESETLOGS.
I admit that I may be missing something but the add/switch/drop routine has
worked for years, causes minimal disruption and is recommended by Oracle (so
it's supported).
Cheers,
Mike Hately
