WebSphere MQ messaging provider connection factory broker properties

Use this panel to view or change the broker settings of the selected connection factory, or topic connection factory, for use with the WebSphere® MQ messaging provider. These broker settings determine how the WebSphere MQ messaging provider interacts with a broker for the purposes of publishing messages and subscribing to topics. Updates to the settings take effect when the server is restarted.

To view WebSphere MQ connection factory, or topic connection factory, broker properties use the administrative console to complete the following steps:
  1. In the navigation pane, click Resources > JMS > Connection factories to display existing connection factories, or click Resources > JMS > Topic connection factories to display existing topic connection factories.
  2. If appropriate, in the content pane, change the Scope setting to the level at which the connection factories are defined. This restricts the set of connection factories displayed.
  3. Select the name of the connection factory, or topic connection factory, that you want to work with.
  4. In the content pane, under Additional Properties, click Broker properties to display the broker properties of the WebSphere MQ connection factory, or topic connection factory.
Under General Properties there are four groups of properties:

Make any required changes to these groups and then click Apply to return to the connection factory, or topic connection factory.

Note: When specifying WebSphere MQ properties, the following restrictions apply:

A WebSphere MQ connection factory, or topic connection factory, has the following broker properties:

Broker control queue

The queue to which broker control messages are sent.

Data type String
Default SYSTEM.BROKER.CONTROL.QUEUE

Broker publication queue

The queue to which publication messages are sent.

Data type String
Default SYSTEM.BROKER.DEFAULT.STREAM

Broker subscriber queue

The queue to which subscription messages are sent.

Data type String
Default SYSTEM.JMS.ND.SUBSCRIBER.QUEUE

Broker connection consumer subscription queue

The queue to which subscription messages that are destined for a connection consumer are sent.

Data type String
Default SYSTEM.JMS.ND.CC.SUBSCRIBER.QUEUE

Version

The version of the broker that is used. This determines some of the capabilities that the broker is assumed to have. For example, whether to use an RFH version 1 or version 2 header in publications.

Data type Radio button
Default Version 1 broker
Range
Version 1 broker
Message selection cannot be specified.
Version 2 broker
Message selection can be specified. If you select this option, you must also complete Specify where message selection occurs.

Specify where message selection occurs

The process in which message selection is performed. This property is enabled only if Version 2 broker was selected.

Data type Drop-down list
Default CLIENT
Range
CLIENT
Message selection is performed in the application server process.
BROKER
Message selection is performed in the broker process.

Subscription store

The process for tracking subscriptions.

Data type Drop-down list
Default MIGRATE
Range
MIGRATE
Any information that is held on queues is migrated to the broker mechanism for persisting subscription information. If subscription information is already persisted using the broker mechanism then specifying a value of Migrate is equivalent to specifying a value of Broker.
BROKER
Internal broker mechanisms are used to track subscription information.
QUEUE
A designated WebSphere MQ queue is used to record information about current subscriptions.

Durable subscription state refresh interval

How often a long running transaction is recreated and used to clean up durable subscriptions, for some versions of the queue manager.

Data type Integer
Default 60000
Range Any positive integer

Subscription cleanup level

How aggressively messages are cleaned up if the subscriber that is expected to consume the messages terminates unexpectedly.

Data type Drop-down list
Default SAFE
Range
SAFE
A conservative algorithm is used to clean up subscriptions.
ASPROP
The cleanup algorithm is determined by a system property.
NONE
No cleanup of subscriptions is performed.
STRONG
An aggressive algorithm is used to clean up subscriptions.

Subscription cleanup interval

How often to check for orphaned subscriptions and clean up messages.

Data type Integer
Default 3600000
Range Any positive integer

Subscription wildcard format

The wildcard format used for subscribing to more than one topic in a topic hierarchy.

Data type Drop-down list
Default character wildcards
Range
character wildcards
You can use an asterisk (*) or question mark (?) to represent characters, or strings of characters, in a topic name.
* is interpreted as matching many characters.
? is interpreted as matching a single character.
topic level wildcards
You can use a plus sign (+) or number sign (#) to represent topics in a multilevel topic hierarchy.
+ is interpreted as matching a single topic name.
# is interpreted as matching many topics in the hierarchy. / is used to delimit topics.

Publish acknowledgement window

The number of messages to publish before publishing a message that requires broker acknowledgement

Data type Integer
Default 25
Range Any positive integer

Optimize for sparse subscription patterns

An option to specify whether this connection factory is anticipated to receive a high proportion of messages that match its selection criteria. This information can be used to optimize message delivery.

Data type Check box
Default Cleared
Range
Cleared
Subscriptions frequently receive matching messages.
Selected
Subscriptions do not frequently receive matching messages.

Broker queue manager

The name of the queue manager that is running the broker, if it is not the same as the queue manager to which the connection factory connects.

Data type String
Default The queue manager name that was specified in the connection factory.
