Job submission and output processing

IBM® provides a number of facilities you can use to customize the way MVS™ processes jobs and job output. You can use these facilities to:

Override the IBM-provided default job processing characteristics
Monitor, change, or supplement the JCL users use to submit a job
Cancel a job
Tailor the way the TSO/E SUBMIT, CANCEL, OUTPUT, and STATUS commands work
Delete, release, or reroute job output
Submit jobs as a surrogate user

JES2 or JES3, depending on which you have, provides the default job processing characteristics. You can use JES initialization statements to change these defaults.

TSO/E, JES2, JES3, and SMF all provide exits that enable you to further customize job and output processing. TSO/E provides two exits, one for the SUBMIT command and one for the CANCEL, OUTPUT, and STATUS commands. TSO/E also provides default routines for these exits. The SUBMIT default exit allows users to use the SUBMIT command as they wish. The default exit for the CANCEL, OUTPUT, and STATUS commands allows users to examine the status of any job. It prohibits users, however, from using the CANCEL or OUTPUT commands on any job other than their own. For more information, see Customizing the SUBMIT command and job output processing.
