JMS Topic: Monitoring: Durable Subscribers

Buttons     Column Display     Configuration Options     Advanced Configuration Options     Related Tasks     Related Topics

Use this page to monitor and manage durable subscribers that are running on a JMS topic. From this page, you can view detailed runtime statistics for each durable subscriber, as well as create new durable subscribers or delete existing ones.

Click on a subscriber to view its configuration details. To view a subscriber's messages, select the check box next to its name, and then click the Show Messages button.

Durable subscribers are persisted to a disk-based file store or a JDBC-accessible database until the message has been delivered to the subscribers or has expired, even if those subscribers are not active when the message is delivered. A durable subscriber registers a durable subscription with a unique identity that is retained by JMS. Subsequent subscriber objects with the same identity resume the subscription in the state it was left by the prior subscriber. If there is no active subscriber for a durable subscription, JMS retains the subscription's messages until they are received by the subscription or until they expire.

Client ID

A unique client identifier for this durable subscriber.

Note: The client ID is not necessarily equivalent to the WebLogic Server username; that is, a name used to authenticate a user in the WebLogic security realm. You can set the client ID to the WebLogic Server username if it is appropriate for your JMS application.

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.ClientID

Client ID Policy

The policy for the client identifier for this durable subscriber.

Note: The client ID policy is either Restricted or Unrestricted.

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.ClientIDPolicy

Subscription Sharing Policy

The SubscriptionSharingPolicy on this subscriber.

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.SubscriptionSharingPolicy

No Local Messages

Specifies whether this durable subscriber receives local messages that it has published.

To prevent this, set the noLocal parameter to true.

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.NoLocal

Active

Indicates whether this subscription is being used by a durable subscriber.

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.Active

Selector

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.MessagesCurrentCount

Bytes Pending Count

The number of bytes pending by this durable subscriber.

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.BytesPendingCount

Bytes Current Count

The number of bytes received by this durable subscriber.

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.BytesCurrentCount

Last Messages Received Time in Millis

The time when the last time a subscriber received a message from the subscription. The returned value is a standard java absolute time, which is measured in milliseconds since midnight, January 1, 1970 UTC

This returns the JMS durable subscription boot time if there were no messages that were successfully delivered to any subscriber on this subscription since the subscription was booted. We define the boot time of a durable subscription to be the time the subscription is originally created or recovered during a server reboot or jms migration, which ever is latest.

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.LastMessagesReceivedTime

Subscribers Total Count

The total number of subscribers that have accessed this subscription since the creation or the last reboot of the subscription, whichever is later.

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.SubscribersTotalCount

Subscribers High Count

The highest number of subscribers that have shared this subscription at the same time since the creation or the last reboot of the subscription, which ever is later.

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.SubscribersHighCount

Subscribers Current Count

MBean Attribute:
JMSDurableSubscriberRuntimeMBean.SubscribersCurrentCount
