Alternatively, you size it until redo_log_space_wait goes away from v$system_events.

Yep,

wrong tree. size it like: redo blocks per tx * tx/sec * 3/2 *<physical blocksize>

Hello,

I have been wondering about how to work out what the optimal LOG_BUFFER parameter,
compared to the physical size of the REDOLOG file, for the best optimization and writes from buffer to log.
Or am I barking up the wrong tree? Is there some other way of doing this.

i.e. redolog file size is 10M and LOG_BUFFER is 512000. Can this be optimized better?
