Version 5 WebSphere queue destination settings

Use this panel to view or change the configuration properties of the selected JMS queue destination for point-to-point messaging by WebSphere Application Server Version 5 applications.

A queue destination is used to configure a JMS queue of the default messaging provider for use by WebSphere Application Server Version 5 applications. Connections to the queue are created by the associated V5 Default Messaging WebSphere queue connection factory. To view this page, use the administrative console to complete the following steps:

1. In the navigation pane, click Resources > JMS Providers > V5 Default Messaging.

2. (Optional) In the content pane, change the Scope setting to the level at which JMS resources are visible to applications. If you define a Version 5 JMS resource at the Cell scope level, all users in the cell can look up and use that JMS resource. However, the JMS resource has only the subset of properties that apply to WebSphere Application Server Version 5. If you want to define a JMS resource at Cell level for use on non-Version 5 nodes, you should define the JMS resource for the Version 6 default messaging provider.

3. Under Additional Resources, click WebSphere 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.

A JMS queue for use with the internal WebSphere JMS provider has the following properties.

Configuration tab

Scope

The level to which this resource definition is visible to applications.

Resources such as messaging providers, namespace bindings, or shared libraries can be defined at multiple scopes, with resources defined at more specific scopes overriding duplicates which are defined at more general scopes.

The scope displayed is for information only, and cannot be changed on this panel. If you want to browse or change this resource (or other resources) at a different scope, change the scope on the messaging provider settings panel, then click Apply , before clicking the link for the type of resource.

Data type

String

Name

The name by which the queue is known for administrative purposes within IBM WebSphere Application Server.

To enable applications to use this queue, add the queue name to the Queue Names field on the panel for the JMS server that hosts the queue.

Data type

String

JNDI name

The JNDI name that is used to bind the queue into the application server's name space.

As a convention, use the fully qualified JNDI name; for example, in the form jms/Name, where Name is the logical name of the resource.

This name is used to link the platform binding information. The binding associates the resources defined by the deployment descriptor of the module to the actual (physical) resources bound into JNDI by the platform.

Data type

String

Description

A description of the queue, for administrative purposes

Data type	String
Default	Null

Category

A category used to classify or group this queue, for your IBM WebSphere Application Server administrative records.

Data type

String

Persistence

Whether all messages sent to the destination are persistent, non-persistent, or have their persistence defined by the application

Data type	Enum
Default	APPLICATION DEFINED
Range	APPLICATION DEFINED Messages on the destination have their persistence defined by the application that put them onto the queue. NON PERSISTENT Messages on the destination are not persistent. PERSISTENT Messages on the destination are persistent. When a persistent message is put to a queue, all of the message data is written to the messaging log (under the embedded_messaging_install\log directory) to make recovery of the message possible.

Priority

Whether the message priority for this destination is defined by the application or the Specified priority property

Data type	Enum
Default	APPLICATION DEFINED
Range	APPLICATION DEFINED The priority of messages on this destination is defined by the application that put them onto the destination. QUEUE DEFINED [WebSphere MQ destination only] Messages on the destination have their persistence defined by the WebSphere MQ queue definition properties. SPECIFIED The priority of messages on this destination is defined by the Specified priority property.If you select this option, define a priority on the Specified priority property.

Specified priority

If the Priority property is set to Specified, type here the message priority for this queue, in the range 0 (lowest) through 9 (highest)

If the Priority property is set to Specified, messages sent to this queue have the priority value specified by this property.

Data type	Integer
Units	Message priority level
Default	0
Range	0 (lowest priority) through 9 (highest priority)

Expiry

Whether the expiry timeout for this queue is defined by the application or the Specified expiry property, or messages on the queue never expire (have an unlimited expiry timeout)

Data type	Enum
Default	APPLICATION DEFINED
Range	APPLICATION DEFINED The expiry timeout for messages on this queue is defined by the application that put them onto the queue. UNLIMITED Messages on this queue have no expiry timeout, so those messages never expire. SPECIFIED The expiry timeout for messages on this queue is defined by the Specified expiry property.If you select this option, define a timeout on the Specified expiry property.

Specified expiry

If the Expiry timeout property is set to Specified, type here the number of milliseconds (greater than 0) after which messages on this queue expire

Data type	Integer
Units	Milliseconds
Default	0
Range	Greater than or equal to 0 0 indicates that messages never timeout Other values are an integer number of milliseconds
