Powerhouse + Oracle-9i + AIX - Response issues

Hi Bob,
What is the difference between the dynamic SQL generated by Powerhouse/Quiz with and without a VIAINDEX on a CHOOSE statement?!
Is there a way to see that syntax? I know DBAUDIT helps only if you write SQL cursor within QUIZ. I would like to see the SQL code generated for Oracle at run time.
Thanks
Sagar Goparaju

I don't recall that we support the use of index hints. There's certainly
nothing in the manual from prior to 8.3 and nothing like that has been
added more recently. PowerHouse prefers to push as much as possible on
the database for a select and let's the database decide how to retrieve.

I believe that index hints are part of Oracle's own implementation of
SQL, and are not part of the ANSI SQL standard...which is the dialect of
SQL that PowerHouse understands.
You need to stick with ANSI standard SQL (SQL92 I think, although if
conformance has been updated maybe Bob D. can jump in here).

My SQL query thru SqlPlus works fine. But gives the following error in
Quiz:
$ quiz auto=cur2.qzs

DMS-E-GENERAL, A general exception has occurred during operation

What is wrong with my cursor syntax? My intension is to use Index Hint.
Without the index hint, my query works fine. But it is taking longer
than simple quiz request with a choose viaindex.
Thanks very much

You may have to do some logic recoding and push more of the work to the
database. What I mean is writing cursors to use in the access
statements.

We are in the process of migration from AS400 Powerhouse to Powerhouse
on AIX under Oracle environment.
We have successfully converted our application and almost ready for
the production move. But we have been experiencing response issues.
Powerhouse under Oracle environment is relatively very slow.
Any of you have gone thru similar issues when migrated to Oracle
environment? What steps have you taken to improve the response? We have
a huge Cobol routine that runs off of our quick screens using DO
EXTERNAL. That is also taking longer time and a big concern to our
clients.
Please let me know if you have any suggestions or information.
Thanks very much
