Designing an XZIQUE global user exit program

The functions of your XZIQUE exit should be designed:
  1. To control of the number of tasks (and the amount of associated resource) that are waiting in a queue for a free intersystem session. Waiting tasks can degrade the performance of the local system.
  2. To detect poor response from the receiving (remote) system and to notify the operator (or automatic operations program).
  3. To cause CICS® to issue a message when the link resumes normal operation.

The XZIQUE global user exit parameter list is designed to support these objectives.
