I can get some sample code tomorrow, but in a nutshell this is the flow:

1. Before you attempt to connect, put a simple SELECT count(*) INTO l_result from TABLE_1;

2. Check the SQLCA.sqlCode. The results will tell you if you succeeded or failed.

3. If you succeeded, then you are already connected!

Hi Santosh;

   Sounds like a message that gets issues from your PB App. I would also assume that its related around issuing the Connect DB command. I would review your source code and see exactly where & why that message gets displayed.

Hi Chris,

My issue is almost same accept for that i terminate session from server side manually. when my app starts login window makes connection and my report window when call retrieve it takes long time because i know query is too complex. This is okay but during retrieval when i terminate session from server side and reopen report window which in fact checking connection with Connect Using SQLCA; the SQLCODE returned tells me that transaction is already connected while connection was broken manually. So i was in the impression that Connect statement will give me SQLCODE that is not negative while i get -1. How should i identify a broken link in my app?

True regards
