We've recently changed edasprof to use client cursors rather than running them on the server side and have seen improvements across the board (sometimes from several minutes to just a few seconds). There is documentation on this setting here.

I was wondering if anyone else has done this as well and if they have run into any issues with this. We mostly use a single connection/adapter and don't typically report from multiple instances. Also, do you guys know of any other settings that can help (like is there a setting to increase the RAM for agents?).

Thanks a lot,
-J

Hi J,

If it's set for CLIENT does it queue reports from multiple instances?

Also, have you tried messing around with SERVER and FETCHSIZE as 100 as suggested in the documentation?

I'm going to try this as soon as I have some spare time.

The CLIENT setting does only read one answer set from the same instance. However, we rarely run into this problem. The few times we do we can override the setting back to SERVER (or blank). I have tried working with FETCHSIZE (it is set to 100 by default I think). If I increase it to 5000 it only improves runtime by a few seconds max.

Word of Warning, If you are using a bunch complicated match statements or other techniques that require multiple instances the report will break and you will need to override the setting for those specific reports.

Multiple table file (and hold) statements work fine as do sql passthru statements.
