JMS Connection Factory --> Configuration --> General

Name

An alphanumeric name for this JMS 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

JNDIName

The JNDI name 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

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

Dynamic: yes

Default Priority

The default priority used for messages when 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: 0

Maximum: 9

Default: 4

Dynamic: yes

Default Time To Live

The maximum length of time, in milliseconds, that a message will exist. This value is used for messages when a priority is 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

Dynamic: yes

Default Time To Deliver

The delay time, 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

Dynamic: 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

Dynamic: yes

Default Redelivery Delay

The 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

Dynamic: yes

Messages Maximum

The maximum number of messages that can 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.

For ordered redelivery of messages to occur for asynchronous consumers, this must explicitly set to 1 on the connection factory used by the receiving application.

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.

Note: For topic subscribers that use the multicast extension, also see the Overrun Policy attribute.

MBean: weblogic.management.
configuration.
JMSConnectionFactoryMBean

Attribute: MessagesMaximum

Minimum: -1

Maximum: 2147483647

Default: 10

Dynamic: yes

Overrun Policy

The policy to use when the number of outstanding multicast messages reaches the value specified in Messages Maximum and some messages must be discarded.

• 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

Dynamic: 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

Valid values:

• true

• false

Dynamic: 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

Dynamic: yes

Load Balancing Enabled

For distributed destinations, specifies whether non-anonymous producers sending to a distributed queue or topic are load balanced on a per-send 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

Valid values:

• true

• false

Dynamic: 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

Valid values:

• true

• false

Dynamic: yes
