A standard mission (MIG, PRT, BKP, RST, or RSM) should be used for regular production missions.
An emergency mission (EMG, EPR, EBK, ERS, or ERM) should be used for emergency production events.
A cyclic mission (CPR, CRS, or CRM) usually accumulates requests from various users and performs them at intervals (for example, every two hours). After a cyclic mission has finished executing, it returns to WAIT SCHEDULE state. It then executes again depending on its runtime scheduling criteria.
A cyclic printing mission is often used when the Control-D monitor’s primary use is SYSOUT printing. In such a case, it is common to activate a cyclic printing mission that wakes up every few minutes, and prints reports which were captured from the spool since the last invocation of the cyclic printing mission.
It is possible to retrieve regular cyclic, cyclic or emergency missions selectively when using the Online facility. This provides an additional means of control.
Emergency missions remain in the Active Missions file until all regular missions of the same GROUP finish executing OK. When an emergency mission is no longer needed, it is removed from the Active Missions file. This process is performed once a day by the Control-V New Day procedure. For details, see the Control-D and Control-V chapter of the INCONTROL for z/OS Administrator Guide.
Note: BMC recommends that parameter GROUP be specified if you define emergency missions. If GROUP is not specified, the mission may remain indefinitely in the Active Missions file.
Parameter ON PAGE# can be used to trigger (cyclic) printing missions when the number of pages waiting to be printed exceeds a specified threshold.
