Sun Microsystems IP HL 7, TCP Monitoringthe HL7 Adapter

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.

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

dataows, 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.

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.

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.

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 Adapter

Youcan 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 dened in the HL7 Adapter web application's deployment

descriptorle, web.xml. Below is an excerpt from the le dening the time period.
