Arslan - Yes, I agree with Bunyamin. I perform weekly analyzes on my OLTP databases. This allows me to create a history of table growth for capacity projections. I have found a weekly measure of table rows is a reasonable balance between the ability to catch unexpected events and the effort required. Also, it is easier to remember that other time intervals, like every 10 days, for example. However, when you first put a new application into production, you may want to analyze it more frequently. I would recommend Burleson's book Oracle High-Performance Tuning with STATSPACK for scripts that will help you implement this. Dennis Williams DBA Lifetouch, Inc. [EMAIL PROTECTED]

If small number of of data change occurs you may need to do it monthly . But I have read somewhere that Analyze is recommended for every week for oltp databases.
