WebSphere MQ messaging provider topic connection factory advanced properties
Use this panel to view or change 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.
- In the navigation pane, click to display existing topic connection factories.
- If appropriate, in the content pane, change the Scope setting to the level at which the topic connection factories are defined. Setting the scope in this way restricts the set of queue connection factories displayed.
- Select the name of the topic connection factory that you want to work with.
- 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.
- Client reconnect
- Message compression
- Temporary destinations
- Connection consumer
- Message format
- Additional
Make any required changes to these groups and then click Apply to return to the topic connection factory.
- Names can have a maximum of 48 characters, except for channels, which have a maximum of 20 characters.
- The property values that you specify must match the values that you specified when configuring JMS resources for WebSphere MQ. For more information about configuring JMS resources for WebSphere MQ, see the Using Java™ section of the WebSphere MQ documentation.
A WebSphere MQ topic connection factory has the following advanced properties.
Client reconnect options
This property specifies whether a client mode connection reconnects automatically, or not, in the event of a communications or queue manager failure. This parameter is ignored unless the connection factory is being used in a thin or managed client environment.
Information | Value |
---|---|
Data type | Drop-down list |
Default | DISABLED |
Range |
|
For more information about automatic client reconnection, see the WebSphere MQ information center.
Client reconnect timeout
The maximum number of seconds that a client mode connection spends attempting to automatically reconnect to a queue manager after a communications or queue manager failure. This parameter is ignored unless the connection factory is being used in a thin or managed client environment. Whether this parameter is used or not depends on the value of the client reconnect options parameter.
Information | Value |
---|---|
Data type | Integer |
Units | Seconds |
Default | 1800 (30 minutes) |
Range | A value greater than zero and up to 2147483647 |
For more information about automatic client reconnection, see the WebSphere MQ information center.
Compress message headers
An option that enables the compression of message headers.
Information | Value |
---|---|
Data type | Check box |
Default | Cleared |
Range |
|
Compression algorithm for message payloads
The compression algorithm to use to compress message payloads.
Information | Value |
---|---|
Data type | Drop-down list |
Default | NONE |
Range |
|
Temporary topic prefix
The prefix to append to the beginning of the names generated for temporary topics.
Information | Value |
---|---|
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.
Information | Value |
---|---|
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.
Information | Value |
---|---|
Data type | Integer |
Default | 10 |
Range | A value greater than zero. |
Coded character set identifier
The character set to use when you are encoding strings in the message.
Information | Value |
---|---|
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. |
For more information about supported CCSIDs, and about converting between message data from one coded character set to another, see the System Administration and the Application Programming Reference sections of the WebSphere MQ information center.
Fail JMS method calls if the WebSphere MQ messaging provider queue manager is quiescing
An option that enables selected JMS operations to fail when the queue manager is put into a quiescing state. Selecting this option enables the queue manager to quiesce successfully and shut down.
Information | Value |

Data type | Check box |
Default | Selected |
