Hi Jared,=20 Yes, I saw that. The connections are queued up until they can be handed off, not until processing is complete. Correct? So a long-running query can be handled in this environment without affecting other connection requests given it is configured properly.=20 Am I missing something?

Queries all queue up behind the shared servers.=20 Jared "Koivu, Lisa" <Lisa.Koivu@xxxxxxxxxxxxxxx> Sent by: oracle-l-bounce@xxxxxxxxxxxxx 02/18/2004 12:17 PM Please respond to oracle-l =20 To: <oracle-l@xxxxxxxxxxxxx> cc:=20 Subject: RE: ora-12500 on windows Juan, why do you say that MTS is only for short quick queries? Can you elaborate? I think I know why but I'd like to hear your side.

You can have both, once you configure shared server you can configure some computers to be dedicated. ----- Original Message -----=3D20 From: "DENNIS WILLIAMS" <DWILLIAMS@xxxxxxxxxxxxx> To: <oracle-l@xxxxxxxxxxxxx> Sent: Wednesday, February 18, 2004 3:25 PM Subject: RE: ora-12500 on windows Lisa Maybe I'm a little simple, but in this situation I would be pressing the vendor (Informatica) for a solution. Taking the point of view that "your application has a problem". They may well have a solution or a suggestion. After all, they've been around awhile. Just a thought from a simple mind that hates to solve problems others have already solved.

Informatica fires in the neighborhood of 300 connections all at the same time, the exact same second. I have tried adding multiple listeners, adding the QUEUESIZE parameter, all to no avail. I had to reduce the sga size to stop the errors. =3D3D20 To make this more interesting, I am guaranteed that in the future there will be several hundred more concurrent connections added to what I'm dealing with now. =3D3D20 Can anyone comment - can MTS help in my situation? I've never used it. Any comments or suggestions are welcome.
