Re: How to trace a Windows session

I'd expect from your description that you are seeing a web application written using the .net framework, or straight vbscript/asp? If this is the case it's more than likely that you have some sort of connection pooling in place, in which case there is no guarantee at all that the session you see will be the one that gets the error.

I'd say that the appropriate course of action would be

1. Get the developers to instrument their code. (this can sometimes be achieved you know).
2. Failing 1 (much more common) I'd be tempted to create a logon trigger to set trace for that particular user. http://www.petefinnigan.com/ramblings/how_to_set_trace.htm has a number of examples.
3. 10g and dbms_monitor might be more targetted and useful - though to be honest if the code is written well enough to get the action/module or client info into v$session in the first place the developers are likely to be amenable to approach 1 anyway.
