Introduction to System z Operating System – z/OS MVS Commands – CANCEL Ø Use the CANCEL command to end an active job, started task, or timesharing user immediately. The table that follows summarizes the tasks that the CANCEL command can perform. Following the table are usage notes, the complete command syntax, definition of parameters, and examples of use. Ø If the program that supports the job or started task was designed to recognize the STOP command, use the STOP command before using the CANCEL command. If the CANCEL command fails several times, consider using the FORCE command. 2/25/2021 © Copyright IBM Corp. , 2008. All rights reserved. 3

Introduction to System z Operating System – z/OS Subsystem Commands Ø Subsystems such as JES, RACF, DB 2, Web. Sphere MQSeries have system programmer assigned command recognition characters used to prefix subsystem commands. This assigned prefix instructs z/OS which subsystem is to be passed the command. Ø Several methods for determining assigned subsystem command prefix § D OPDATA (will provide DB 2, JES 2 and Web. Sphere MQSeries info) § Search for all occurrences of IEE 252 I in SYSLOG ü ‘MEMBER IEFSSN## FOUND IN ‘system parameter library name’ ü Inspect each IEFSSN## entry for subsystem command recognition prefix 2/25/2021 © Copyright IBM Corp. , 2008.
