JMS – PSS Characteristics (Magic xpi 3.x)

You use PSS messaging when messages can be processed by single or multiple consumers. These are the main characteristics of a PSS messaging domain:

• Each message may have multiple consumers.

• Publishing and subscribing objects have a time dependency. A client that subscribes to a topic can only consume messages published after the client has created a subscription, and the subscriber must continue to be active to consume messages.

• The JMS API relaxes time dependency by allowing clients to create durable subscriptions.
