Designing an XZIQUE global user exit program
The functions of your XZIQUE exit should be designed:
- 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.
- To detect poor response from the receiving (remote) system and to notify the operator (or automatic operations program).
- 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.
