The Adapter is kept informed of changes to the Alcatel-Lucent network by the Alcatel-Lucent 5620 SAM EMS server. The mechanism by which this is accomplished is called Java Messaging Service (JMS). The Adapter normally connects to the server using “durable” connections. This means that if the Adapter goes down, the server will queue up changes that are taking place and deliver those changes to the Adapter when it reconnects. The Adapter is known to the Alcatel-Lucent 5620 SAM EMS server by its JmsUniqueId.
The presence of an unused JMS durable connection causes the Alcatel-Lucent 5620 SAM EMS to accumulate transactions that will never be delivered to the Adapter, consuming unnecessary disk space. The durable connections in the Alcatel-Lucent 5620 SAM EMS server are recorded in the 5620sam/server/nms/jboss/server/default/conf/jbossmq-state.xml file.
VMware Corporation recommends that you remove an unused JMS connection in order to release the server from its “obligation” to store undelivered transaction, if you have changed the value of the JmsId parameter in the emsConfig.import file.
To remove an unused JMS durable connection from the 5620 Sam server, use the Alcatel-Lucent 5620 SAM EMS GUI. The Alcatel-Lucent 5620 SAM EMS documentation provides instructions.
