A generic decollating mission can be defined for a specific job name but is usually used in conjunction with a generic job name. A generic job name is specified using mask characters. Execution of the generic decollating mission is triggered by the appearance of a job (whose name matches the job name mask) in a specific output class (in non‑held status). These output classes are defined in the Control‑D installation parameters. The appearance of a matching job name in other output classes (or in held status in the generic classes) does not trigger the execution of a generic decollating mission.
A generic decollating mission can decollate only from the generic classes defined in the Control‑D installation parameters. Any output that is decollated by a generic decollating mission is purged from spool. After decollation, the mission’s postprocessing parameters (OUT, SHOUT) are executed, but the mission does not stay in ENDED status. It is recycled for re‑execution (that is, it is in WAIT SCHEDULE status).
All runtime scheduling criteria (IN, TIME, PRIORITY) are applicable to generic decollating missions. Usually the recycled generic mission is immediately eligible for execution and is assigned the WAITING FOR JOB status.
SYSOUTs of jobs that appear in a generic class but do not have a matching generic decollating mission name in the Active Missions file are removed from the generic class in one of the following ways, depending on the value specified in Control‑D installation parameter GENOTFND:
Table 133 Removal of SYSOUTs of Generic CLass Jobs
Value |
Description |
|---|---|
Values that are valid under JES2: |
|
PRIORITY |
The spool priority of the output is set to one. This allows other output with higher priority to be processed. Default. |
DELETE |
The output is deleted from the spool. |
HOLD |
The spool status of the output is altered to hold, preventing it from being processed again by Control‑D generic decollation class monitoring. |
CLASS=x |
The class of the output is altered to the specified class. This class must not be one of the classes specified in parameter GENCLAS. |
Values that are valid under JES3: |
|
DELETE |
The output for which there is no associated scheduled generic decollation mission is deleted from the spool. |
CLASS=x |
The class of the output is altered to the specified class. This class must be defined as HOLD=EXTWTR. It must not be one of the classes specified in parameter GENCLAS. |
For more information on specifying values for parameter GENOTFND, see the discussion about specifying Control‑D parameters, in the Control‑D chapter of the INCONTROL for z/OS Installation Guide: Installing.
