Inquire Storage Class Names on z/OS

The Inquire Storage Class Names (MQCMD_INQUIRE_STG_CLASS_NAMES) command inquires a list of storage class names that match the generic storage class name specified.


Required parameters

    StorageClassName (MQCFST)
    Storage class name (parameter identifier: MQCA_STORAGE_CLASS).

    Generic storage class names are supported. A generic name is a character string followed by an asterisk (*), for example ABC*, and it selects all storage classes having names that start with the selected character string. An asterisk on its own matches all possible names.

    The maximum length of the string is MQ_STORAGE_CLASS_LENGTH.


Optional parameters

    CommandScope (MQCFST)
    Command scope (parameter identifier: MQCACF_COMMAND_SCOPE). Specifies how the command is executed when the queue manager is a member of a queue-sharing group. We can specify one of the following:

    • blank (or omit the parameter altogether). The command is executed on the queue manager on which it was entered.
    • a queue manager name. The command is executed on the queue manager you specify, providing it is active within the queue sharing group. If you specify a queue manager name other than the queue manager on which it was entered, you must be using a queue sharing group environment, and the command server must be enabled.
    • an asterisk (*). The command is executed on the local queue manager and is also passed to every active queue manager in the queue sharing group.

    The maximum length is MQ_QSG_NAME_LENGTH.

    QSGDisposition (MQCFIN)
    Disposition of the object within the group (parameter identifier: MQIA_QSG_DISP). This parameter applies to z/OS® only. Specifies the disposition of the object (that is, where it is defined and how it behaves). The value can be any of the following values:

      MQQSGD_LIVE
      The object is defined as MQQSGD_Q_MGR or MQQSGD_COPY. MQQSGD_LIVE is the default value if the parameter is not specified.

      MQQSGD_ALL
      The object is defined as MQQSGD_Q_MGR or MQQSGD_COPY.

      If there is a shared queue manager environment, and the command is being executed on the queue manager where it was issued, this option also displays information for objects defined with MQQSGD_GROUP.

      If MQQSGD_LIVE is specified or defaulted, or if MQQSGD_ALL is specified in a shared queue manager environment, the command might give duplicated names (with different dispositions).

      MQQSGD_COPY
      The object is defined as MQQSGD_COPY.

      MQQSGD_GROUP
      The object is defined as MQQSGD_GROUP.

      MQQSGD_Q_MGR
      The object is defined as MQQSGD_Q_MGR.

      MQQSGD_PRIVATE
      The object is defined with either MQQSGD_Q_MGR or MQQSGD_COPY. MQQSGD_PRIVATE returns the same information as MQQSGD_LIVE.
