Inquire Queue Names

The Inquire Queue Names (MQCMD_INQUIRE_Q_NAMES) command inquires a list of queue names that match the generic queue name, and the optional queue type specified.

Required parameters

QName (MQCFST)

Queue name (parameter identifier: MQCA_Q_NAME).

Generic queue names are supported. A generic name is a character string followed by an asterisk (*), for example ABC*, and it selects all objects 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_Q_LENGTH.

Optional parameters

CommandScope (MQCFST)

Command scope (parameter identifier: MQCACF_COMMAND_SCOPE). This parameter applies to z/OS only. Specifies how the command is processed 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 processed on the queue manager on which it was entered.
• a queue manager name. The command is processed 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, we must be using a queue sharing group environment, and the command server must be enabled.
• an asterisk (*). The command is processed 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 for which information is to be returned (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_GROUP is permitted only in a shared queue environment.

MQQSGD_Q_MGR

The object is defined as MQQSGD_Q_MGR.

MQQSGD_PRIVATE

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

MQQSGD_SHARED

The object is defined as MQQSGD_SHARED. MQQSGD_SHARED is permitted only in a shared queue environment.

QType (MQCFIN)

Queue type (parameter identifier: MQIA_Q_TYPE). If present, this parameter limits the queue names returned to queues of the specified type. If this parameter is not present, queues of all types are eligible. The value can be any of the following values:

MQQT_ALL

All queue types.

MQQT_LOCAL

Local queue.

MQQT_ALIAS

Alias queue definition.

MQQT_REMOTE

Local definition of a remote queue.

MQQT_MODEL

Model queue definition.

The default value if this parameter is not specified is MQQT_ALL.
