Inbound HL7 V2 Collaboration - Part 3

After the ACK is sent, the HL7 V2 message and the ACK are journaled to the JMS queue Journal destination. If the message fails to journal, the associated recourse action is taken.

If sequence numbering is enabled, the processAckNakSequenceNumbering method calculates the next sequence number and stores the number in the sequence number file by calling the updateSequenceNumberFile method to persist the next sequence number.
