Time Dependent Operation user exit
The controller calls the Time Dependent Operation user exit each time an operation become ready in a z/OS® environment, in order to know if a negative or positive offset must be added to the job start time, to decide if the operation can be started or not. The controller uses the returned offset to update the job start time only. In particular, the process leaves unchanged the latest start time.
The exit receives as input from the controller some data identifying the job, to be used by the exit to decide the appropriate offset to be calculated.
When implementing the exit remember that the workstation name,
passed as input parameter, is the one on which the operation is defined.
As a consequence, the submission destination might be unknown at exit
invocation time, in the following conditions:
- An alternate workstation is defined. In this case, consider defining the alternate workstation equivalent to the primary workstation, from an offset calculation point of view.
- The workstation is defined with the virtual option. In this case, define the virtual workstation in the UX14IN file.
