Itis expected that, when enabled, the journal queue has one or more subscribers that process the
contentsof the queue so that it remains manageable. For example, the Batch Adapter or a
databaseAdapter could periodically consume the messages by writing them to a le or a
database.
ErrorQueues
TheAdapter provides a mechanism to store failed or stripped messages in a JMS queue or topic.
Theadvantage of this is that the messages are then saved in a form readily usable by the other
dataows, that can automatically process these messages or make them available to some type
ofhuman intervention or message repair, using tools like the JMS queue editor or an eVision
application.
Alertsand Monitoring
Ifthe Adapter loses the connection to the external system in any direction or connection type,
dueto a crash, shutdown, or suspension (including recourse actions), an alert is generated. The
monitor’sstatus of that Adapteris changed to “down” and the Adapter’s icon is encased in a red
warningbox. The monitor also displays the number of messages it has processed along with the
dateand time of the last message sent.
Supportfor HL7 Version 2.5 SFT Segments
HL7version 2.5 adds a new SFT segment to every message. The Adapter not only sends and
receivesmessages with the new segment, it can automatically create and populate them, using
informationfrom the Adapter properties, for the outbound message and the ACK sent from the
inboundmode. This feature is only available when the Version ID property is set to 2.5 or later.
DelayedAcknowledgements
TheAdapter supports delayed acknowledgements in either direction and in a number of roles.
Thisfunctionality is described in detail in “Outbound Adapter Roles for Delayed ACK
Scenarios”on page 18.
Monitoringthe HL7 AdapterYoucan monitor the status of the HL7 Adapter in the deployed Projects that include the
adapter.This includes viewing alerts and log messages, checking connector details, and
monitoringexternal connections. This is done on the Enterprise Manager. For more
informationabout using the Enterprise Manager Monitor, see Using Enterprise Manager
ManagementApplication in Java CAPS.
Foroutbound HL7 Adapters, periodic monitoring for external connections is performed. The
timeperiod is based on the value dened in the HL7 Adapter web application's deployment
descriptorle, web.xml. Below is an excerpt from the le dening the time period.
