Dick ,
Thanks a ton for ur feedback. I ran UTLBSTAT/UTLESTAT and found out that the problem was with memory. Then I went and queried V$SGASTAT, V$SQLAREA, V$SQLTEXT. Can u tell me if there can be any other problems ? I found out later that there were some indexes added afterwards.
Thanks nyways.

Chetan,First questions, What changed? Did someone add/delete an index? Was therean oversized data load done? When were the statistics, if present, lastcomputed? Has a new program/application been added to the server? Did a memorybank go offline? Did a disk interface card go offline?I use HP's HP-UX boxes as well, except most of my DB's are 10 times largerthen yours. Just about everytime something like that happens, especially all ofa sudden, one of those questions is the cause. The last item I'd go lookingfor, have only had one instance of it so far, is a unrestricted user whoreleased "the query from HELL" into the database as a "one time requirement". If you can find him/her I've a used gallows rope is still here, one usage only.Dick GouletReply SeparatorAuthor: Chetan Date: 6/26/2002 2:18 AMHi guys ,Need some help.
