■Monitoring
TheEnterprise Manager provides a real-time picture of the Adapter's state and status. The
monitoringfacilities display the following information:
■Adapterup or down
■Connectedto external
■Currentsequence number
■Dateand time of the last transaction
■Adapterproperties
■Alerts
Alertsare sent from the RA and the Collaborations when conditions are identied that
endangeror stop the interface. You can add your own custom alert messages to the
Collaborations.
■Logging
Logmessages are written from both the RA and the Collaborations. You can also congure
yourown log messages. The level is set in the Enterprise Manager. For more information on
monitoring,alerting and logging, see Using Enterprise Manager Management Application in
JavaCAPS and Alert Codes for Java CAPS Adapters.
Modes and Roles
TheTCP/IP HL7 Adapter can operate in two modes: standard and delayed ACK. Standard
modeis the typical message exchange in HL7 where an HL7 message is sent and an HL7 ACK is
received,or the other way around. In delayed ACK mode, the exchange of a message requires
twoacknowledgements: one to conrm the message was received and the other from the
externalsystem that actually received the message to verify that it was received.
Inthese two modes, the Adapter and the ESB have a number of roles they play within certain
scenarios;that is, certain components can fulll dierent responsibilities within a protocol. For
example,the outbound Collaboration can fulll two roles in the delayed ACK mode: one as the
“senderof messages” that expects two delayed ACKS, and another as the “forwarder of ACKS”
fromthe external system.
Note– Delayed ACK mode is deprecated as of HL7 version 2.2 and was removed from the HL7
standardas of version 2.5.

StandardMode

Instandard mode, the HL7 Adapter can assume two roles, sender and receiver. These are
implementedin the outbound and inbound Collaborations respectively.
