Overview

This tab defines general configuration attributes for a JMS connection factory. After defining a JMS server, you can configure one or more connection factories to create connections with predefined attributes.

Attributes

Attribute Label | Description | Value Constraints
--- | --- | ---
Name | An alphanumeric name for this connection factory configuration. This field will not accept spaces. Each JMS connection factory configuration in a WebLogic domain must have a unique name, regardless of the server instance or cluster in which it resides. WebLogic Server uses an MBean to implement and persist the configuration. MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: Name | Configurable: yes Readable: yes Writable: yes
JNDIName | This is the name that is assigned to and used to look up the connection factory within the JNDI namespace. The connection factory name is configured separately. MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: JNDIName | Configurable: yes Readable: yes Writable: yes
Client Id | An optional client ID for a durable subscriber that uses this connection factory. Configuring this value prevents more than one JMS client from using a connection from the factory. Generally, JMS durable subscriber applications set their client IDs dynamically using the javax.jms.Connection.setClientID() call. MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: ClientId | Configurable: yes Dynamic: yes Readable: yes Writable: yes
Default Priority | The default priority used for messages for which a priority is not explicitly defined. Message producers can get the Priority explicitly by calling the javax.jms.MessageProducer.getPriority() method. MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: DefaultPriority | Minimum: PRIORITY_MINIMUM Maximum: PRIORITY_MAXIMUM Default: PRIORITY_DEFAULT Configurable: yes Dynamic: yes Readable: yes Writable: yes
Default Time To Live | The default maximum length of time, in milliseconds, that a message will exist. Used for messages for which a priority was not explicitly defined. A value of 0 indicates that the message has an infinite amount time to live. Message producers can get the Time To Live explicitly by calling the javax.jms.MessageProducer.getTimeToLive() method.MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: DefaultTimeToLive | Minimum: 0 Maximum: 9223372036854775807 Default: 0 Configurable: yes Dynamic: yes Readable: yes Writable: yes
Default Time To Deliver | Defines the delay, in milliseconds, between when a message is produced and when it is made visible on its destination. Message producers can get the Time To Deliver explicitly by calling the weblogic.jms.extensions.WLMessageProducer.getTimeToDeliver() method. MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: DefaultTimeToDeliver | Minimum: 0 Maximum: 9223372036854775807 Default: 0 Configurable: yes Dynamic: yes Readable: yes Writable: yes
Default Delivery Mode | The delivery mode assigned to all messages sent by a producer using this connection factory Message producers can get the Delivery Mode explicitly by calling the javax.jms.MessageProducer.getDeliveryMode() method. MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: DefaultDeliveryMode | Default: PERSISTENT Valid values: PERSISTENT NON_PERSISTENT Configurable: yes Dynamic: yes Readable: yes Writable: yes
Default Redelivery Delay | The amount of delay time, in milliseconds, before rolled back or recovered messages are redelivered. Message consumers can get the Redelivery Delay explicitly by calling the weblogic.jms.extensions.WLSession.getRedliveryDelay() method. MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: DefaultRedeliveryDelay | Minimum: 0 Maximum: 9223372036854775807 Default: 0 Configurable: yes Dynamic: yes Readable: yes Writable: yes
Messages Maximum | The maximum number of messages that may exist for an asynchronous session and that have not yet been passed to the message listener. A value of -1 indicates that there is no limit on the number of messages. In this case, however, the limit is set to the amount of remaining virtual memory. A value of 0 is not valid and will cause exceptions to be thrown. When the number of messages reaches the Messages Maximum value: For multicast sessions, new messages are discarded according the policy specified by the Overrun Policy attribute and a DataOverrunException is thrown. For non-multicast sessions, new messages are flow-controlled, or retained on the server until the application can accommodate the messages. For multicast sessions, when a connection is stopped, messages will continue to be delivered, but only until the Messages Maximum value is reached. Once this value is reached, messages will be discarded based on the Overrun policy. MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: MessagesMaximum | Minimum: -1 Maximum: 2147483647 Default: 10 Configurable: yes Dynamic: yes Readable: yes Writable: yes
Overrun Policy | The policy to use when the number of outstand.ing multicast messages reaches the value specified in MessagesMaximum and some messages must be discarded, as follows: If set to Keep New, the most recent messages are given priority over the oldest messages, and the oldest messages are discarded, as needed. If set to Keep Old, the oldest messages are given priority over the most recent messages, and the most recent messages are discarded, as needed. Message age is defined by the order of receipt, not by the JMSTimestamp value. MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: OverrunPolicy | Default: Keep Old Valid values: Keep Old Keep New Configurable: yes Dynamic: yes Readable: yes Writable: yes
Allow Close In On Message | Specifies whether the connection factory creates message consumers that allow a close() or stop() method to be issued within its onMessage() method call. If selected (true), a close() or stop () method call from within an onMessage() method call will succeed instead of blocking forever. If the acknowledge mode of the session is set to AUTO_ACKNOWLEDGE, the current message will still be acknowledged automatically when the onMessage() call completes. If not selected (false), it will cause the stop() and close() methods to hang if called from onMessage(). This attribute is dynamic and can be changed at any time. However, changing the value does not affect existing connections. It only affects new connections made with this connection factory. MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: AllowCloseInOnMessage | Default: false Configurable: yes Dynamic: yes Readable: yes Writable: yes
Acknowledge Policy | The acknowledge policy for non-transacted sessions that use the CLIENT_ACKNOWLEDGE mode. The All policy specifies that calling acknowledge on a message acknowledges all unacknowledged messages received on the session. The Previous policy specifies that calling acknowledge on a message acknowledges only unacknowledged messages up to, and including, the given message. Note: This attribute works around a change in the JMS specification. Specifically, the specification allowed users to acknowledge all messages before and including the message being acknowledged. The specification was changed so that acknowledging any message acknowledges all messages ever received (even those received after the message being acknowledge), as follows: MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: AcknowledgePolicy | Default: All Valid values: All Previous Configurable: yes Dynamic: yes Readable: yes Writable: yes
Load Balancing Enabled | For distributed destinations, specifies whether non-anonymous producers created through a connection factory are load balanced within a distributed destination on a per-call basis. If true, the associated message producers will be load balanced on every send() or publish(). If false, the associated message producers will be load balanced on the first send() or publish(). MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: LoadBalancingEnabled | Default: true Dynamic: yes Readable: yes Writable: yes
Server Affinity Enabled | For distributed destinations, specifies whether a WebLogic Server that is load balancing consumers or producers across multiple physical destinations (queues or topics) in a distributed destination, will first attempt to load balance across any other physical destinations that are also running on the same WebLogic Server. MBean: weblogic.management. configuration. JMSConnectionFactoryMBean Attribute: ServerAffinityEnabled | Default: true Readable: yes Writable: yes
