Example of Defining Scheduling Defaults

To provide defaults for TP profiles that do not specify certain scheduling parameters, code a parmlib member that contains a TPDEFAULT statement.

Figure 1. ASCHPM3A

  TPDEFAULT
     REGION(2M)
     TIME(1,30)
     MSGLEVEL(1,0)
     OUTCLASS(J)

This TPDEFAULT example specifies that:

The amount of virtual storage assigned to the TP is 2M.
TPs that take longer than 1 minute 30 seconds of CPU time will be abnormally terminated.
All statements and messages issued during TP profile add and modify processing will be generated, but statements and messages issued when a TP profile is accessed to run a TP will be generated only if the TP abnormally terminates.
J is the class used as a default MSGCLASS for TPs whose profiles do not specify the MSGCLASS keyword in their JOB statements. (When the SYSOUT keyword does not include a specific output class, the value of MSGCLASS can be used as a default. Thus, OUTCLASS can affect how SYSOUT is processed.)

To activate these values in member ASCHPM3A, issue the SET command as follows:

  SET ASCH=3A

Scheduling defaults for the system can be viewed by issuing the following DISPLAY command:

  DISPLAY ASCH,SUMMARY
