This attribute can be used to control how strictly the certificate
chain validation conforms to industry security standards. For more
information about certificate validation policies, see Certificate

- 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 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.

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

restart manager (ARM) restarts the channel initiator, the z/OS command SET
APPC=
xx
is issued. This parameter is valid only
on z/OS.
- LU62CHL
- The maximum number of channels that can be current, or
clients that can be connected, that use the LU 6.2 transmission protocol.
If the value of LU62CHL is zero, the LU 6.2 transmission protocol
is not used.
This parameter is valid only on z/OS.
- MARKINT
- The mark browse
interval in milliseconds.
Attention: This value should not be below the default of
5000.
- MAXCHL

server-connection channels with connected clients).
This parameter
is valid only on z/OS.
- MAXHANDS
- The maximum number of open handles that any one connection
can have at any one time.
- MAXMSGL
- The maximum message length that can be handled by the
queue manager. Individual queues or channels might have a smaller

be associated with a message.
This parameter is valid only on IBM i, z/OS, UNIX, Linux, and Windows systems.

of this parameter is MVS (for z/OS platforms),
NSK, OS2, OS400, UNIX, or WINDOWSNT.
- PSCLUS

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

- SCYCASE
- Whether the security profiles are uppercase or mixed
case.
This parameter is valid 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
WebSphere MQ Advanced Message Security (WebSphere MQ AMS) capabilities are available to the queue
manager. If the WebSphere MQ AMS component is installed for the version of WebSphere MQ that the
queue manager is running under, the attribute has a value ENABLED
(MQCAP_SUPPORTED)
. If the WebSphere MQ AMS component is not installed, the value is
DISABLED (MQCAP_NOT_SUPPORTED)
.
- 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
