JMS Connection Factory: Configuration: Default Delivery
Configuration Options Related Tasks Related Topics
Use this page to define the default delivery configuration parameters for this JMS connection factory, such as the default delivery mode, default time to live, etc.
Configuration Options
Name Description Default Priority The default priority used for messages when a priority is not explicitly defined.
All messages with a DefaultPriority of -1 that are produced on a connection created with this factory will receive this value. Message producers can get the priority explicitly by calling the
javax.jms.MessageProducer.getPriority()method.This attribute is dynamic. It 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 Attribute (Does not apply to application modules) :
DefaultDeliveryParamsBean.DefaultPriorityMinimum value:
0Maximum value:
9Default Time-to-Live The maximum length of time, in milliseconds, that a message exists. This value is used for messages when both the
time-to-liveis not explicitly set by the sender application that is using this connection factory and thetime-to-liveis not explicitly overridden by the destination'sTimeToLiveOverrideattribute . A value of 0 indicates that the message has an infinite amount time to live.Message producer applications can set the
time-to-liveexplicitly by calling the standard JMSjavax.jms.MessageProducer.setTimeToLive(long)method. Note that programmatically settingtime-to-liveusingjavax.jms.Message.setJMSExpiration()has no effect - the message setter is ignored by the JMS send call as required by the JMS specification.This attribute is dynamic. It 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 Attribute (Does not apply to application modules) :
DefaultDeliveryParamsBean.DefaultTimeToLiveMinimum value:
0Maximum value:
9223372036854775807Default Time-to-Deliver The delay time, in milliseconds, between when a message is produced and when it is made visible on its destination.
All messages produced by a producer created with this factory that have a DefaultTimeToDeliver of -1 will use this value. Message producers can get the Time-to-Deliver explicitly by calling the
weblogic.jms.extensions.WLMessageProducer.getTimeToDeliver()method.This attribute is dynamic. It 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 Attribute (Does not apply to application modules) :
DefaultDeliveryParamsBean.DefaultTimeToDeliverDefault Delivery Mode The default delivery mode used for messages when a delivery mode is not explicitly defined.
All messages with a DefaultDeliveryMode of
nullthat are produced on a connection created with this factory will receive this value. Message producers can get the delivery mode explicitly by calling thejavax.jms.MessageProducer.getDeliveryMode()method.This attribute is dynamic. It 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 Attribute (Does not apply to application modules) :
DefaultDeliveryParamsBean.DefaultDeliveryModeDefault Redelivery Delay The delay time, in milliseconds, before rolled back or recovered messages are redelivered.
All messages consumed by a consumer created with this factory that have a DefaultRedeliveryDelay of -1 will use this value.
Message consumers can get the redelivery delay explicitly by calling the
weblogic.jms.extensions.WLSession.getRedliveryDelay()method.This attribute is dynamic. It 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 Attribute (Does not apply to application modules) :
DefaultDeliveryParamsBean.DefaultRedeliveryDelayMinimum value:
0Maximum value:
9223372036854775807Send Timeout The maximum length of time, in milliseconds, that a sender will wait when there isn't enough available space (no quota) on a destination to accommodate the message being sent.
The default time is 10 milliseconds. A value of 0 indicates that the sender does not want to wait for space.
This attribute is dynamic. It can be changed at any time. However, changing the value does not affect existing connections or their producers. It only affects new connections made with this connection factory. Producers inherit the setting from the connection factory used to create their session and connection. The value can then be overridden at run time by setting the value on the producer.
MBean Attribute (Does not apply to application modules) :
DefaultDeliveryParamsBean.SendTimeoutMinimum value:
0Maximum value:
9223372036854775807Default Compression Threshold The number of bytes for the serialized message body so any message exceeds this limit will trigger message compression when the message is sent or received by the JMS message producer or consumer.
The compression will occur either:
On the JMS message producer's JVM if the JMS message producer's JVM is not collocated with the JMS provider's JVM and the message body size exceeds the threshold limit.
On the JMS provider's JVM when the JMS message consumer's JVM is not collocated with the JMS provider's JVM and the message body size exceeds the threshold limit.
MBean Attribute (Does not apply to application modules) :
DefaultDeliveryParamsBean.DefaultCompressionThresholdMinimum value:
0Maximum value:
2147483647Default Unit-of-Order for Producer The default Unit-of-Order name for producers that connect using this connection factory. A Unit-of-Order allows for messages to be processed in a certain order, even among multiple recipients.
System-generatedindicates that WebLogic Server will automatically generate a Unit-of-Order name.User-Generatedindicates that the Unit-of-Order name will come from the name specified name in theUnit-of-Order Namefield. IfNoneis selected, no message ordering is enforced.MBean Attribute (Does not apply to application modules) :
DefaultDeliveryParamsBean.DefaultUnitOfOrderChanges take effect after you redeploy the module or restart the server.
User-generated Unit-of-Order Name Specifies the Unit-of-Order name when the Default Unit-of-Order for Producer value is set to User-generated.
