Inquire Cluster Queue Manager

The Inquire Cluster Queue Manager (MQCMD_INQUIRE_CLUSTER_Q_MGR) command inquires about the attributes of IBM® MQ queue managers in a cluster.

HP Integrity NonStop Server	IBM i	UNIX and Linux®	Windows	z/OS®

Required parameters

ClusterQMgrName (MQCFST)

Queue manager name (parameter identifier: MQCA_CLUSTER_Q_MGR_NAME).

Generic queue manager names are supported. A generic name is a character string followed by an asterisk *, for example ABC*. It selects all queue managers having names that start with the selected character string. An asterisk on its own matches all possible names.

The queue manager name is always returned, regardless of the attributes requested.

The maximum length of the string is MQ_Q_MGR_NAME_LENGTH.

Optional parameters

Channel (MQCFST)

Channel name (parameter identifier: MQCACH_CHANNEL_NAME).

Specifies that eligible cluster queue managers are limited to those having the specified channel name.

Generic channel names are supported. A generic name is a character string followed by an asterisk *, for example ABC*. It selects all queue managers 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_CHANNEL_NAME_LENGTH.

If you do not specify a value for this parameter, channel information about all queue managers in the cluster is returned.

ClusterName (MQCFST)

Cluster name (parameter identifier: MQCA_CLUSTER_NAME).

Specifies that eligible cluster queue managers are limited to those having the specified cluster name.

Generic cluster names are supported. A generic name is a character string followed by an asterisk *, for example ABC*. It selects all queue managers 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_CLUSTER_NAME_LENGTH.

If you do not specify a value for this parameter, cluster information about all queue managers inquired is returned.

ClusterQMgrAttrs (MQCFIL)

Attributes (parameter identifier: MQIACF_CLUSTER_Q_MGR_ATTRS).

Some parameters are relevant only for cluster channels of a particular type or types. Attributes that are not relevant for a particular type of channel cause no output, and do not cause an error. To check which attributes apply to which channel types; see Channel attributes and channel types.

CommandScope (MQCFST)

Command scope (parameter identifier: MQCACF_COMMAND_SCOPE). This parameter applies to z/OS only.

Specifies how the command is executed when the queue manager is a member of a queue-sharing group. You can specify one of the following values:

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. 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.

You cannot use CommandScope as a parameter to filter on.

IntegerFilterCommand (MQCFIF): Integer filter command descriptor. The parameter identifier must be any integer type parameter allowed in ClusterQMgrAttrs except MQIACF_ALL and others as noted. Use this parameter to restrict the output from the command by specifying a filter condition. See MQCFIF - PCF integer filter parameter for information about using this filter condition.
If you specify an integer filter, you cannot also specify a string filter using the StringFilterCommand parameter.

StringFilterCommand (MQCFSF)

String filter command descriptor. The parameter identifier must be any string type parameter allowed in ClusterQMgrAttrs except MQCA_CLUSTER_Q_MGR_NAME and others as noted. Use this parameter to restrict the output from the command by specifying a filter condition. See MQCFSF - PCF string filter parameter for information about using this filter condition.

If you specify a string filter for Channel or ClusterName, you cannot also specify the Channel or ClusterName parameter.

If you specify a string filter, you cannot also specify an integer filter using the IntegerFilterCommand parameter.
