The log buffer is flushed when any of the the follwoing occur (i) 1 MB is filled up (2) 1/3rd is filled up (3) every 3 seconds (4) when a checkpoint occurs (5) when a commit occurs. Therefore, see if any of these could be the problem. It's easy to check #s 4 and 3. As Kirti suggested, the problem could be due to the redo logs being on a busy disk, or even a slow one. HTH.

I would also check if the redo logs are on a busy disk. If so, try moving those (or other busy data files on the same disk) to other not-so-busy disks. - Kirti===== Have a nice day !! ------------------------------------------------------------ Best Regards, K Gopalakrishnan, Bangalore, INDIA. -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: K Gopalakrishnan INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
