Attempts to do an ISPF split session in Jobtrac results in message '@TRACFAIL - JOBTRAC? DD CARD NOT FOUND IN TIOT OR TOKEN GIVEN INVALID'.
Jobtrac does not allow its ISPF session to use split screen (to allow for two Jobtrac sessions). If invoked, message: '@TRACFAIL - JOBTRAC? DD CARD NOT FOUND IN TIOT OR TOKEN GIVEN INVALID' is issued.
When this message is issued you will lose access to session1 and session2, you will then need to log off and then back on to re-establish the Jobtrac ISPF session. This occurs because the Jobtrac client for session2 frees any allocation that was allocated in session1.
