WebSphere MQ queue settings (MQ Config)

Use this panel to browse or change the configuration properties defined to WebSphere MQ for the selected queue destination.

To view this page, use the administrative console to complete the following steps:

1. In the navigation pane, expand Resources > JMS Providers > WebSphere MQ.

2. If appropriate, in the content pane, change the scope of the WebSphere MQ messaging provider. If the scope is set to node or server scope for a Version 5 node, the administrative console presents the subset of resources and properties that are applicable to WebSphere Application Server V5.

3. In the content pane, under Additional Resources, click WebSphere MQ Queue Destinations. This displays a list of any existing JMS queue destinations.

4. Click the name of the JMS queue destination that you want to work with.

5. Under Additional Resources, click MQ Config.

A WebSphere MQ queue destination is used to configure the properties of a JMS queue. A queue for use with the WebSphere MQ JMS provider has the following extra properties defined to WebSphere MQ.Notes

Note:

• To be able to browse or change these MQ Config properties, the WebSphere MQ Queue Manager on which the queue resides must be configured for remote administration and be running. You must also have installed the WebSphere MQ client. If you have not done this, the administrative console displays messages like the following

  The WMQQueueDefiner MBean has encountered an error.
  WMSG0331E: The MQ Client is required for this functionality, but it is not installed.
  

• These MQ Config properties can be used only to view or change the properties of local queues. We cannot use MQ Config to administer alias or remote queues.

• Some properties displayed are read-only and cannot be changed.

• The property values that you specify must match the values that you specified when configuring WebSphere MQ JMS resources. For more information about configuring WebSphere MQ JMS resources, see the WebSphere MQ: Using Java book; for example from the WebSphere MQ multiplatform library Web page at http://www.ibm.com/software/ts/mqseries/library/manualsa/manuals/crosslatest.html.

• In WebSphere MQ, names can have a maximum of 48 characters, with the exception of channels which have a maximum of 20 characters.

Data type

String

Password

The password, used with the User ID property, for authentication when connecting to the queue manager to define the queue destination.

If you specify a value for the User ID property, also specify a value for the Password property.

Data type

String

Description

The WebSphere MQ queue description, for administrative purposes within WebSphere MQ.

Data type	String
Default	Null
Range	1 through 64 ASCII characters.

Inhibit Put

Whether or not put operations are allowed for this queue.

Data type	Enum
Default	Put Inhibited
Range	Put Allowed Put operations are allowed for this queue. Put Inhibited Put operations are not allowed for this queue.

Persistence

Whether messages on the queue are persistent or non-persistent.

Data type	Enum
Default	Persistent
Range	Persistent Messages on the queue are persistent. Non persistent Messages on the queue are not persistent.

Cluster Name

The name of the cluster to which the WebSphere MQ queue manager belongs.

If you specify a value for Cluster Name, you should not specify a value for Cluster Name List. Cluster names must conform to the rules described in the WebSphere MQ MQSC Command Reference book.

Data type	String
Default	Null
Range	A valid WebSphere MQ name for a queue manager cluster, as 1 through 48 ASCII characters

Cluster Name List

The name of the cluster namelist to which the WebSphere MQ queue manager belongs.

If you specify a value for Cluster Name, you should not specify a value for Cluster Name List. Cluster names must conform to the rules described in the WebSphere MQ MQSC Command Reference book.

Data type	String
Default	Null
Range	A valid WebSphere MQ name for a list of queue manager clusters, as 1 through 48 ASCII characters

Default Binding

The default binding to be used when the queue is defined as a cluster queue.

Data type	Enum
Default	On Open
Range	On Open The queue handle is bound to a specific instance of the cluster queue when the queue is opened. Not Fixed The queue handle is not bound to any particular instance of the cluster queue. This allows the queue manager to select a specific queue instance when the message is put, and to change that selection subsequently should the need arise.

Inhibit Get

Whether or not get operations are allowed for this queue.

Data type	Enum
Default	Get Inhibited
Range	Get Inhibited Get operations are not allowed for this queue. Get Allowed Get operations are allowed for this queue.

Maximum Queue Depth

The maximum number of messages allowed on the queue.

Data type	Integer
Units	Number of messages
Default	0
Range	A value greater than or equal to zero, and less than or equal to 640 000. For more information about the maximum value allowed, see the WebSphere MQ MQSC Command Reference. If this value is reduced, any messages that are already on the queue are not affected, even if the number of messages exceeds the new maximum.

Maximum Message Length

The maximum length, in bytes, of messages on this queue.

Data type	Integer
Units	Number of bytes
Default	0
Range	A value greater than or equal to zero, and less than or equal to the maximum message length for the queue manager and WebSphere MQ platform. For more information about the maximum value allowed, see the WebSphere MQ MQSC Command Reference. If this value is reduced, any message that is already on the queue are not affected, even if the message length exceeds the new maximum.

Shareability

Message Delivery Sequence

The order in which messages are delivered from the queue in response to get requests.

Data type	Enum
Default	FIFO
Range	FIFO Messages are delivered in first in first out (FIFO) order. Priority is ignored for messages on this queue. Priority Messages are delivered in first-in-first-out (FIFO) order within priority. This is the default supplied with WebSphere MQ, but your installation might have changed it.

Backout Threshold

The maximum number of times that a message can be backed out. If this threshold is reached, the message is requeued on the backout queue specified by the Backout Requeue Name property.

The WebSphere MQ queue manager keeps a record of the number of times that each message has been backed out. When this number reaches a configurable threshold, the connection consumer requeues the message on a named backout queue. If this requeue fails for any reason, the message is removed from the queue and either requeued to the dead-letter queue, or discarded.

Data type	Integer
Default	0
Range	0 Never requeue messages 1 or more The number of times that a message has been backed, at which the message is requeued on a named backout queue.

Backout Requeue Name

The name of the backout queue to which messages are requeued if they have been backed out more than the backout threshold.

The WebSphere MQ queue manager keeps a record of the number of times that each message has been backed out. When this number reaches a configurable threshold, the connection consumer requeues the message on a named backout queue. If this requeue fails for any reason, the message is removed from the queue and either requeued to the dead-letter queue, or discarded.

Data type	String
Default	Null
Range	1 through 48 characters.

Harden Get Backout

Whether hardening should be used to ensure that the count of the number of times that a message has been backed out is accurate.
