WebSphere MQ messaging provider connection factory advanced properties
Use this panel to view or change the advanced properties of the selected 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 connection factory advanced properties, use the administrative console...
- In the navigation pane, click Resources > JMS ->Connection factories to display existing connection factories.
- If appropriate, in the content pane, change the Scope setting to the level at which the connection factories are defined. Setting the scope in this way restricts the set of queue connection factories displayed.
- Select the name of the connection factory 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 connection factory.
Under General Properties there are six groups of advanced properties:
- 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 connection factory.
When specifying WebSphere MQ properties, the following restrictions apply:
- 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 specified when configuring JMS resources for WebSphere MQ. For more information about configuring JMS resources for WebSphere MQ, see the Use Java section of the WebSphere MQ information center.
A WebSphere MQ connection factory has the following advanced properties:
Client reconnect options
New feature: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 WebSphere MQ information center.
Client reconnect timeout
New feature: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
Cleared
Do not compress message headers.
Selected
Compress message headers.
Compression algorithm for message payloads
The compression algorithm used 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.
WebSphere MQ model queue name
The model queue used as a basis for temporary queue creation.
Information Value Data type String Default SYSTEM.DEFAULT.MODEL.QUEUE
Temporary queue prefix
The prefix that is appended to the beginning of the names generated for temporary queues.
Information Value Data type String
Temporary topic prefix
The prefix that is appended to the beginning of the names generated for temporary topics.
Information Value Data type String
Retain messages, even if no matching consumer is available
An option that determines whether messages for which there is no matching consumer are retained on the input queue or dealt with according with their disposition options.
Information Value Data type Check box Default Selected Range
Cleared
Do not retain messages.
Selected
Retain messages.
Polling interval
This setting is applicable in the client container only. When using aWebSphere 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.
Rescan interval
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 retrieves messages from a WebSphere MQ queue before switching to use messages from 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.
The Coded character set identifier (CCSID) is only applicable for connection factory advanced properties if your messaging system is using WebSphere MQ v6.0. If you are using WebSphere MQ Version 7.0 define the CCSID to use for your messages at your queue destination. For more information on how to do this, see WebSphere MQ Provider queue destination settings for application clients.
If the application constructs messages for a WebSphere MQ application that requires a different character or numeric encoding, you can override the character encoding value by setting the JMS_IBM_Character_Set property to the required coded character set ID (CCSID), or the JMS_IBM_Encoding property to the required numeric format, or both. For information about the values you can use for JMS_IBM_Character_Set and JMS_IBM_Encoding, see the documentation in the WebSphere MQ library.
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 Application Programming Reference sections of the WebSphere MQ information center.
Append an RFH version 2 header to reply messages
When sending a reply message to the reply-to queue obtained from a message, select this option to append an RFH version 2 header to the reply message regardless of whether the original message had a RFH version 2 header.
Information Value Data type Check box Default Cleared Range
Selected
Append an RFH version 2 header to reply messages regardless of whether the original message had an RFH version 2 header.
Cleared
Append an RFH version 2 header to reply messages only if the original message had an RFH version 2 header.
Fail JMS method calls if the WebSphere MQ 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.
