Sun Java Composite Application Suite Functionality

The TCP/IP HL7 Adapter takes advantage of the Java CAPS facilities to provide journaling and error messaging, as well as monitoring, alerting, and logging. journaling and error messages are sent to JMS queues, which allow flexibility for postprocessing. For example, invalid messages and their negative acknowledgements (NAKs) are sent to a JMS queue. This JMS queue can then be set up to allow the invalid HL7 messages to be viewed, corrected, and resubmitted automatically to the same Adapter.

• Error Queues

  Each Collaboration automatically sends invalid messages that have incorrect data, have invalid formatting, or are deemed unacceptable to a JMS error queue. The error generated by the message and, if appropriate, its associated NAK, are written as JMS properties of that message for later processing. You can send errors to one common queue, to a specified queue for each Adapter, or to a combination of both.

• Journaling Queues

  When journaling is enabled, the HL7 message and its related acknowledgement (ACK) are written to a JMS journal queue. You determine the number of JMS error queues or journal queues used by a Project. From the JMS queue, these messages can be accessed and written to file, sent to a database, sent to a Web application for processing, and so forth.

• Monitoring

  The Enterprise Manager provides a real-time picture of the Adapter's state and status. The monitoring facilities display the following information:

  • Adapter up or down

  • Connected to external

  • Current sequence number

  • Date and time of the last transaction

  • Adapter properties

• Alerts

  Alerts are sent from the RA and the Collaborations when conditions are identified that endanger or stop the interface. You can add your own custom alert messages to the Collaborations.

• Logging

  Log messages are written from both the RA and the Collaborations. You can also configure your own log messages. The level is set in the Enterprise Manager.
