The name of an authentication information object that is used to provide the location of user ID and password authentication.

CPILEVEL

Reserved, this value has no significance.

CRDATE

The date on which the queue manager was created (in the form yyyy-mm-dd).

CRTIME

The time at which the queue manager was created (in the form hh.mm.ss).

CUSTOM

This attribute is reserved for the configuration of new features before separate attributes have been introduced. It can contain the values of zero or more attributes as pairs of attribute name and value in the form NAME(VALUE).

DEADQ

The name of the queue to which messages are sent if they cannot be routed to their correct destination (the dead-letter queue or undelivered-message queue). The default is blanks.

For example, messages are put on this queue when:

A message arrives at a queue manager, destined for a queue that is not yet defined on that queue manager
A message arrives at a queue manager, but the queue for which it is destined cannot receive it because, possibly:
- The queue is full
- The queue is inhibited for puts
- The sending node does not have authority to put the message on the queue
An exception message must be generated, but the queue named is not known to that queue manager

Note: Messages that have passed their expiry time are not transferred to this queue when they are discarded.

If the dead-letter queue is not defined, or full, or unusable for some other reason, a message that would have been transferred to it by a message channel agent is retained instead on the transmission queue.

If a dead-letter queue or undelivered-message queue is not specified, all blanks are returned for this parameter.

DEFCLXQ

The DEFCLXQ attribute controls which transmission queue is selected by default by cluster-sender channels to get messages from, to send the messages to cluster-receiver channels.

SCTQ

All cluster-sender channels send messages from SYSTEM.CLUSTER.TRANSMIT.QUEUE. The correlID of messages placed on the transmission queue identifies which cluster-sender channel the message is destined for.

SCTQ is set when a queue manager is defined. This behavior is implicit in versions of IBM WebSphere® MQ, earlier than IBM WebSphere MQ 7.5. In earlier versions, the queue manager attribute DEFCLXQ was not present.

CHANNEL

Each cluster-sender channel sends messages from a different transmission queue. Each transmission queue is created as a permanent dynamic queue from the model queue SYSTEM.CLUSTER.TRANSMIT.MODEL.QUEUE.

If the queue manager attribute, DEFCLXQ, is set to CHANNEL,the default configuration is changed to cluster-sender channels being associated with individual cluster transmission queues. The transmission queues are permanent-dynamic queues created from the model queue SYSTEM.CLUSTER.TRANSMIT.MODEL.QUEUE. Each transmission queue is associated with one cluster-sender channel. As one cluster-sender channel services a cluster transmission queue, the transmission queue contains messages for only one queue manager in one cluster. You can configure clusters so that each queue manager in a cluster contains only one cluster queue. In this case, the message traffic from a queue manager to each cluster queue is transferred separately from messages to other queues.

DEFXMITQ

Default transmission queue name. This parameter is the transmission queue on which messages, destined for a remote queue manager, are put if there is no other suitable transmission queue defined.

PSCLUS

Controls whether this queue manager participates in publish subscribe activity across any clusters in which it is a member. No clustered topic objects can exist in any cluster when modifying from ENABLED to DISABLED.

PSMODE

Controls whether the publish/subscribe engine and the queued publish/subscribe interface are running, and therefore controls whether applications can publish or subscribe by using the application programming interface and the queues that are monitored by the queued publish/subscribe interface.

PSNPMSG

If the queued publish/subscribe interface cannot process a non-persistent input message it might attempt to write the input message to the dead-letter queue (depending on the report options of the input message). If the attempt to write the input message to the dead-letter queue fails, and the MQRO_DISCARD_MSG report option was specified on the input message or PSNPMSG=DISCARD, the broker discards the input message. If PSNPMSG=KEEP is specified, the interface only discards the input message if the MQRO_DISCARD_MSG report option was set in the input message.

PSNPRES

If the queued publish/subscribe interface attempts to generate a response message in response to a non-persistent input message, and the response message cannot be delivered to the reply-to queue, this attribute indicates whether the interface tries to write the undeliverable message to the dead-letter queue or whether to discard the message.

PSRTYCNT

When the queued publish/subscribe interface fails to process a command message under sync point (for example a publish message that cannot be delivered to a subscriber because the subscriber queue is full and it is not possible to put the publication on the dead letter queue), the unit of work is backed out and the command tries this number of times again before the broker attempts to process the command message according to its report options instead.

PSSYNCPT

If this attribute is set to IFPER, when the queued publish/subscribe interface reads a publish or delete publication messages from a stream queue during normal operation then it specifies MQGMO_SYNCPOINT_IF_PERSISTENT. This value makes the queued pubsub daemon receive non-persistent messages outside sync point. If the daemon receives a publication outside sync point, the daemon forwards that publication to subscribers known to it outside sync point.

QMID

The internally generated unique name of the queue manager.

QMNAME

The name of the local queue manager. See Rules for naming IBM MQ objects.

QSGNAME

The name of the queue sharing group to which the queue manager belongs, or blank if the queue manager is not a member of a queue sharing group. You can use queue sharing groups only on z/OS.

If this parameter has been altered but the REFRESH SECURITY command has not yet been issued, the queue manager might not be using the case of profiles you expect. Use DISPLAY SECURITY to verify which case of profiles is actually in use.

SPLCAP

Indicates if Advanced Message Security (AMS) capabilities are available to the queue manager. If the AMS component is installed for the version of IBM MQ that the queue manager is running under, the attribute has a value ENABLED. If the AMS component is not installed, the value is DISABLED.

SQQMNAME

When a queue manager makes an MQOPEN call for a shared queue and the queue manager that is specified in the ObjectQmgrName parameter of the MQOPEN call is in the same queue sharing group as the processing queue manager, the SQQMNAME attribute specifies whether the ObjectQmgrName is used or whether the processing queue manager opens the shared queue directly.

This parameter is valid only on z/OS.

SSLCRLNL

Indicates the namelist of AUTHINFO objects being used for the queue manager for certificate revocation checking.

Only authentication information objects with types of CRLLDAP or OCSP are allowed in the namelist referred to by SSLCRLNL. Any other type results in an error message when the list is processed and is subsequently ignored.
