Dear DBA

I have 130 gb database running on 7/24 basis. redo logfile size is 40mb and oracle create about most to 400 archivive log. that mean log switch happend at 3-4 min at peak time.

As oracle suggest, it is better log switch between 30min. (Why, if so that need more recovery time?)
If I will increase the size to 100mb and make time around 30 min. How about Log_checkpooint_interval. My currently setting is 2097152 (20mb). log_checkpoint_timeout = 0

As my understand, the interval based on volume. If setting is 100mb, mean 5 check point will occured at 20mb interval. I am right?

Any suggest?

Mitchell
