WebLogic Advanced JMS: Unit of Work
Sr. Principal Product Manager for App Grid, Jeff West, discusses an advanced feature in WebLogic for JMS called Unit Of Work and provides a demo of UOW in action.
Many applications need an even more restricted notion of a group than provided by the Message Unit-of-Order (UOO) feature. If this is the case for your applications, WebLogic JMS provides the Unit-of-Work (UOW) Message Groups, which allows applications to send JMS messages, identifying some of them as a group and allowing a JMS consumer to process them as such. For example, an JMS producer can designate a set of messages that need to be delivered to a single client without interruption, so that the messages can be processed as a unit. Further, the client will not be blocked waiting for the completion of one unit when there is another unit that is already complete.
