EQA1990E Invalid session parameter - session_parameter
Explanation
Conversation initialization failed. A batch program, attempting to start an LU 6.2 debug session, has passed an invalid Session Parameter. For example, LU2 or MFI has been specified for session type or a session ID longer than eight characters has been specified. For a description of the Session Parameter and its contents, see the z/OS® Debugger manual.
Programmer response
Correct the Session Parameter and invoke the batch application again.
