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.

You can show fewer or additional data points on this page by expanding Customize this table and modifying the Column Display list. Each data point displays in its own table column.
The following table lists all of the data points that you can display in columns on this page.
Name Description Subscription Name The subscription name for this durable subscriber. This name must be unique for each client ID.
Valid durable subscription names cannot include the following characters: comma ",", equals "=", colon ":", asterisk "*", percent "%", or question mark"?".
MBean Attribute:
JMSDurableSubscriberRuntimeMBean.SubscriptionNameClient 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.ClientIDClient ID Policy The policy for the client identifier for this durable subscriber.
Note: The client ID policy is either
RestrictedorUnrestricted.MBean Attribute:
JMSDurableSubscriberRuntimeMBean.ClientIDPolicySubscription Sharing Policy The Subscription Sharing Policy on this subscriber.
MBean Attribute:
JMSDurableSubscriberRuntimeMBean.SubscriptionSharingPolicyNo Local Messages Specifies whether this durable subscriber receives local messages that it has published.
To prevent this, set the
noLocalparameter totrue.MBean Attribute:
JMSDurableSubscriberRuntimeMBean.NoLocalActive Indicates whether this subscription is being used by a durable subscriber.
MBean Attribute:
JMSDurableSubscriberRuntimeMBean.ActiveSelector The message selector defined for this durable subscriber.
MBean Attribute:
JMSDurableSubscriberRuntimeMBean.SelectorMessages Pending Count The number of messages pending (uncommitted and unacknowledged) by this durable subscriber.
MBean Attribute:
JMSDurableSubscriberRuntimeMBean.MessagesPendingCountMessages Current Count The number of messages still available by this durable subscriber.
MBean Attribute:
JMSDurableSubscriberRuntimeMBean.MessagesCurrentCountBytes Pending Count The number of bytes pending by this durable subscriber.
MBean Attribute:
JMSDurableSubscriberRuntimeMBean.BytesPendingCountBytes Current Count The number of bytes received by this durable subscriber.
MBean Attribute:
JMSDurableSubscriberRuntimeMBean.BytesCurrentCountLast 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.LastMessagesReceivedTimeSubscribers 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.SubscribersTotalCountSubscribers 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.SubscribersHighCountSubscribers Current Count The number of subscribers that currently share this subscription.
MBean Attribute:
JMSDurableSubscriberRuntimeMBean.SubscribersCurrentCount
