Hi Joel Garry,

  1. Well I used OEM to find out the problematic SQL.
  2. I resolved it by finding the the satetemnt in OEM and I added the index and right after I added it (without restart the test) my hits/second in Load Runner growd up from 1 hit/second to 20 hits/second which is the performance that was on start of test. I also tried test it again and there is no degradation any more in my application.
  3. Yes UPPER cause to full table scan (before I added function based index), but I just want to understand why degradation?
  4. Maybe it is poor design, but I'm not a architecture of company :-)), I'm just regular programmer that try to find out the performance problems in existing for years application.

Thanks,
Maxim. Received on Thu Apr 14 2005 - 04:50:43 CDT
