The Engage HL7 Adapter 1.3 SR1 (1.3.2) solution is a maintenance release that does not introduce any new features.

The Engage HL7 Adapter 1.4 (1.4.5) solution provides the following new features:

• This adapter has been re-built for compatibility with Platform 5.5.

• This adapter has been updated to improve handling of messages during failover. (ADP-4114, ADP-4336)

• When sending a message because of a fired rule, the adapter opens a new connection only if one does not exist or if the previous one is no longer usable, and the adapter maintains the outbound connection used for at least 60 minutes after the message is sent. (ADP-5308)

• Multiple definitions can be configured for the same segment within a message definition. (ADP-3856)

• Statistics are displayed in the adapter's Details, and can be refreshed without reloading the entire adapter. (ADP-3788)

• The "acknowledgment on a different port" fields have been removed from inbound and outbound connection configuration. (ADP-3453)

• The activity state of ongoing alerts are re-evaluated when the highest priority event within a message receives changes. (ADP-5223)

  If an alert is active and a subsequent message does not contain a currently active alert with the same location settings, then the alert will be inactivated. If a subsequent message does not contain the currently active alert for the location and the highest priority remaining alert is currently suppressed, then a new active alert will be created. If an alert is active and a subsequent message for the same location contains both that alert and a higher priority alert, then the old active alert will be inactivated and a new suppressed alert will be created for it (and a new active alert will be created for the higher priority alert).

The following issues are fixed in Engage HL7 Adapter 1.3 SR1 (1.3.2):

• HL7 can stop marking alerts as inactive. (ADP-5180)

  1. A timing issue can cause a null pointer exception on the date comparison to the most recently received time.
  2. Nothing stops exceptions thrown in the periodic task that marks alerts inactive from being thrown back to the ScheduledExecutorService that runs them, which would cause the job to stop being processed.

  Workaround:

  1. Prevent null pointer exception by initiating/updating time before/during Map insertion processing.
  2. Add try/catch around inactive check to keep it from stopping.

• HL7 file based ID generator can overflow. (ADP-5134)

  Configure the parser that generates the ACK to use a UUID based message id generator instead of the default file based processor that uses sequential numbers.

The following issues are fixed in Engage HL7 Adapter 1.4 (1.4.5):

• Message Type marked for discard no longer causes package export to fail. (ADP-3864)

• Referencing invalid capture groups in HL7 preprocessing rules no longer causes an exception and skew statistics. (ADP-3825)

• HL7 now creates an audit message when it cannot listen on a port because it is already in use. (ADP-2565)
