Sun Adapter for TCP/IP HL7 User's Guide

Journaling

The Adapter provides the option to journal successfully received or sent messages and their corresponding ACKs. The messages are sent to a JMS queue or topic, depending on how you configure the Adapter, and the ACKs are stored as a JMS property, HL7_ACK, of that message.

It is expected that, when enabled, the journal queue has one or more subscribers that process the contents of the queue so that it remains manageable. For example, the Batch Adapter or a database Adapter could periodically consume the messages by writing them to a file or a database.
