RE: SQL Performance Question



fixed

It sounds possible.

The QSYS version is simply a template, it is not ever used.

To set the options system wide, do a CRTDUPOBJ of the QSYS one to QUSRSYS.

Maybe that's part of the problem. We don't have that file in QUSRSYS. It
is in each of the developer's libraries & QSYS but not QUSRSYS.


Thanks!

I had a issue like that and solved it with changing the value of
IGNORE_DERIVED_INDEX in file QUSRSYS/QAQQINI to *YES.

Subject: SQL Performance Question

We have some "SQL" processes that were written by our web development
team.
They were made into stored procedures on the iSeries. When they run
for our
website, they take 15 or 20 seconds, some times more to run. Yet, if
we
take the SQL and run it in Navigator, it takes about 450 ms to run.

Any ideas on how to improve the performance of these stored procedures?

I have created the "suggested" indexes and still no improvement.
