Set a topic connection factory for the WebSphere MQ messaging provider > factory advanced properties

To set the advanced properties of the selected topic connection factory for use with the WebSphere MQ messaging provider. These advanced properties control the behavior of connections made to WebSphere MQ messaging provider destinations.

To view WebSphere MQ topic connection factory advanced properties, use the admin console to complete the following steps:

  1. In the navigation pane, 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 topic connection factories are defined. This restricts the set of topic connection factories displayed.

  3. Selecyt the name of the topic connection factory that you want to work with.

  4. In the content pane, under Additional properties, click Advanced properties to view a list of the advanced properties of the WebSphere MQ topic connection factory.

Under General Properties there are five groups of properties:

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

When specifying WebSphere MQ properties, the following restrictions apply:

A WebSphere MQ topic connection factory has the following advanced properties.

Compress message headers

An option that enables the compression of message headers.

Data type check box
Default Cleared
Range

Cleared

Do not compress message headers.

Selected

Compress message headers.

Compression algorithm for message payloads

The compression algorithm to use to compress message payloads.

Data type Drop-down list
Default NONE
Range

RLE

ZLIBFAST

ZLIBHIGH

NONE

Temporary topic prefix

The prefix to append to the beginning of the names generated for temporary topics.

Data type String

Polling interval

This setting is applicable in the client container only. When using a WebSphere MQ version 6 queue manager (or WebSphere MQ version 5.3 for z/OS), this setting configures the mechanism used to dispatch messages to JMS asynchronous consumers.

This setting is used when the set of WebSphere MQ queues that is being asynchronously consumed from exceeds the number of threads that are available internally to synchronously get messages from the WebSphere MQ queue. The setting determines how long a thread waits for a message to arrive at a WebSphere MQ queue before polling another WebSphere MQ queue in the set.

Data type Integer
Units Milliseconds
Default 5000
Range A value greater than zero.

Maximum batch size

The maximum number of messages that can be removed from a queue before at least one must be delivered to an asynchronous consumer.

Data type Integer
Default 10
Range A value greater than zero.

Coded character set identifier

The character set to use when we are encoding strings in the message.

Data type Integer
Default 819
Range A value greater than zero. The coded character set identifier (CCSID) must be one of the CCSIDs supported by WebSphere MQ.

See about supported CCSIDs, and about converting between message data from one coded character set to another, see the WebSphere MQ System Administration and the WebSphere MQ Application Programming Reference sections of the WebSphere MQ library.

Fail JMS method calls if the WebSphere MQ messaging provider queue manager is quiescing

An option that enables selected JMS operations to fail fail when the queue manager is put into a quiescing state. Selecting this option enables the queue manager to quiesce successfully and shutdown.

Data type Check box
Default Selected
Range

Cleared

Do not fail JMS operations if the queue manager is quiescing.

Selected

Fail JMS operations if the queue manager is quiescing.
