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 Version 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.

- 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.

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

is used or whether the processing queue manager opens the shared queue directly. This
parameter is valid only on z/OS.
