RE: Cognos anyone?




Thank you for your post.

I have tried materialized views, but they did not work that well for us
because the reports that the users
wanted would have demanded a separate MV almost of every report. Can you
explain the second
part of your approach - publishing only object in Cognos catalog? I am not
sure what you are referring to here.

My problem right now is that whenever I get a question from a user "why is
my report too slow", the report
in question is so big and so convoluted I can't understand what it does.
Only if I see a full table scan
or a unneded cartesian join, I can possibly pinpoing a problem. In many
cases I can't even paste
the SQL into a vi file because it is too big. How are you dealing with

thank you

I support Cognos here. We create either materialized views for simple
views and publish only those objects in the Cognos catalog. Anything
else is madness. You cannot control the end users in the Cognos
environment. They will do what they will. It's best to have a Cognos
unit that works with the DBA's to publish what needs to be accessed.

Good Luck!

Subject: Cognos anyone?

Hello , everyone:

Does anyone out there have to support Cognos? We are in the process of
migrating to it from microstrategy and
I'm having a hard time dealing with the SQL it creates. They are huge.
several pages long and absolutely undecipherable.
I was wondering if anyone has any hints for working with that thing.

thank you
