There are about 50 User working with this instance. > The bottom line is that you can increase db_block_buffers until the system starts to page and/or swap processes. So, if you are already paging then you can't add anything to db_block_buffers w/o reducing performance. If you are NOT paging then you can increase it by some amount and watch the system for paging activity. You can use sar to determine if paging is taking place. HP may have something better for you to use. -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Brian D.
