START CHINIT

START CHINIT ENVPARM(jcl-substitution)
  • CMDSCOPE(' ')CMDSCOPE(qmgr-name)
  • 1
  • Notes:

    • 1 Valid only on z/OS when the queue manager is a member of a queue-sharing group.


    Usage notes

    1. The command server must be running.
    2. Although START CHINIT is permitted from CSQINP2, its processing is not complete (and the channel initiator is not available) until after CSQINP2 processing has finished. For these commands, consider using CSQINPX instead.


    Parameter descriptions for START CHINIT

      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.

        ' '
        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.

      ENVPARM( jcl-substitution )
      The parameters and values to be substituted in the JCL procedure (xxxxCHIN, where xxxx is the queue manager name) that is used to start the channel initiator address space.

        jcl-substitution
        One or more character strings of the form keyword=value enclosed in single quotation marks. If we use more than one character string, separate the strings by commas and enclose the entire list in single quotation marks, for example ENVPARM('HLQ=CSQ,VER=520').

        This parameter is valid only on z/OS.

      INITQ( string )
      The name of the initiation queue for the channel initiation process. This is the initiation queue that is specified in the definition of the transmission queue.

      The initiation queue on z/OS is always SYSTEM.CHANNEL.INITQ).
