IBM 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 IBM MQ messaging provider. These advanced properties control the behavior of connections made to IBM MQ messaging provider destinations.

To view IBM MQ topic connection factory advanced properties, use the administrative 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. Setting the scope in this way restricts the set of queue connection factories displayed.

  3. Select the name of the topic connection factory to work with.

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

Under General Properties there are six groups of advanced properties:

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

When specifying IBM MQ properties, the following restrictions apply:

An IBM 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

DISABLED

Client reconnection does not automatically occur.

ASDEF

The value from the DefRecon attribute from the channels stanza of the client configuration file is used. If there is no DefRecon value specified in the client configuration file, ASDEF has the same effect as DISABLED.

QMGR

Reconnection occurs only to the queue manager to which the connection was originally connected.

RECONNECT

Reconnection occurs to any queue manager that is consistent with the value of the queue manager attribute. This queue manager might be a different queue manager from the one to which the connection was originally connected.

For more information about automatic client reconnection, see the IBM 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 IBM MQ information center.


Compress message headers

An option that enables the compression of message headers.

Information Value
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.

Information Value
Data type Drop-down list
Default NONE
Range

RLE

Message data compression is performed using run-length encoding.

ZLIBFAST

Message data compression is performed using ZLIB encoding with speed prioritized.

ZLIBHIGH

Message data compression is performed using ZLIB encoding with compression prioritized.

NONE

No message data compression is performed.


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 an IBM MQ Version 6 queue manager (or IBM 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 IBM MQ queues being used asynchronously consumed from exceeds the number of threads available internally to synchronously get messages from the IBM MQ queue. The setting determines how long a thread waits for a message to arrive at an IBM MQ queue before polling another IBM 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 we 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 IBM 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 IBM MQ information center.


Fail JMS method calls if the IBM 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
Range

Cleared

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

Selected

Fail JMS operations if the queue manager is quiescing.
