When you develop an ETL job on DataStage if your connection got lost your session may not close. And you try to re-open your job probably you will get an error like this ;
To handle this error we need to disconnect the session.
First we need to get in IIS Console with standart link – or you may use the shortcut on your local computer if you have one.
After logging in open Administration tab , Session Management and then Active Sessions.
You can see active sessions list below. Find the Session ID that in error.
Check it and you can disconnect it.
It is that easy.
