Can the database identify the type of app server connection, OAS,Jboss,etc

Question

I'm mostly concerned with identifying if it's a Oracle App server connection. I can't find anything in the sys_context, but I might be missing it.
thanks.

Thanks for your answers and questions.
Here are the answers to your questions
1)The jdbc driver is jturboJTurbo? Never heard of it. You mean this?

Why pay for something when you have two options available that are free? One of them is from Microsoft itself. Whose idea was this?
2)It's a desk top application.
It seems to me that it should not be driver issue. I was this happened the Microsoft's own jdbc driver. By jdbc specification, although you don't close the connection explicitly in the program, the connection will be automatically closed in the java app end during garbage collection. Very bad - never depend on this. Always close your ResultSet, Statement, and Connection in reverse order of opening in a finally block, each one wrapped in individual try/catch blocks.
One should never, ever depend on the GC to take care of resources like database connections or resource handles. Those should be cleaned up by your code.
I tested this by intentionally not closing a connection. When I stops the application, the connection in the sql server end was also closed.
But if you don't close the application and fail to close connections, you can see where eventually you'll exhaust the pool.
It seems to me this is a sql server issue rather than a jdbc driver issue. I need way to prove this.
Like I suggested, it's easy to swap in the jTDS driver and try it again. What do you have to lose?
Or call Microsoft support and ask them. Or maybe JTurbo. You're paying for it - might as well use the support.
