    Parameter descriptions for DELETE SUB

      subscription-name
      The local name of the subscription definition to be deleted.

      CMDSCOPE
      This parameter applies to z/OS only and specifies how the command runs when the queue manager is a member of a queue sharing group. CMDSCOPE must be blank, or the local queue manager, if QSGDISP is set to GROUP.

        ' '
        The command runs on the queue manager on which it was entered. This is the default value.

        qmgr-name
        The command runs on the queue manager you specify, providing the queue manager is active within the queue sharing group.

        We can specify a queue manager name other than the queue manager on which the command was entered, only if you are using a queue sharing group environment and if the command server is enabled.

        *
        The command runs on the local queue manager and is also passed to every active queue manager in the queue sharing group. The effect of this is the same as entering the command on every queue manager in the queue sharing group.

      We cannot use CMDSCOPE as a filter keyword.

      SUBID( string )
      The internal, unique key identifying a subscription.
