OPERATOR-CANCEL subcommand

z/OS TSO/E System Programming Command Reference
SA32-0974-00

Use the CANCEL subcommand to terminate the current session of a terminal user. When you use the CANCEL subcommand to terminate the session, the system displays accounting information to the user.

The syntax of the CANCEL subcommand of OPERATOR is:

  • If a user is currently logged on, specify
    • c u=userid
    to terminate that user.
  • If a user is attempting to logon and the logon has not completed or cannot complete, the system rejects the command:
    • c u=userid
    In this case, issue
    • d ts a
    In the display, note the ‘userids’ shown as *LOGON* and their corresponding ASIDs. Then issue
    • c u=*logon*,a=asid

    to terminate a particular user.

  • If a logon completes before the CANCEL command takes effect, the system rejects the command:
    • c u=*logon*,a=asid
    In this case, reissue
    • c u=userid

    to terminate the user.
