JMS Queues JMS Queues In a cluster configuration, the JMS queues are associated with one member of the server cluster. Access to the queues is provided by the Java Naming and Directory Interface (JNDI) service. The JDNI service is available across all the members on the cluster as shown in the following diagram. Cluster Configuration The sequential queue is accessible to all cluster members to produce messages into the queue. Additionally, messages are read by a single-threaded cron task to support first-in-first-out processing. The continuous queue is multi-threaded on the consumer side. The queue supports message processing in high volumes. In this queue, the message processing order is not considered. Enterprise service messages that use the sequential queue, are processed in a strict sequential order. Message processing is single-threaded. Clustering does not significantly impact the processing performance of messages through the sequential queue. 189
