All the tables and indexes are analyzed. Only difference is, if trace is on, it runs faster. if trace is off, it runs slower.

I set up the trace on/off thru logon/logoff trigger for that application user till the problem is resolved. I am cleaning up the udump directory using a script.

Thanks.

when tables are not analyzed or your stats are old, the moon can make queries run at different speeds. thats usually what does it. reanalyzed the tables.
