28.1 Chapter 14 Contents (14.1)

28.2 Introduction (14.2)

The information in this chapter was relocated from Appendix C as of v2.4 of the standard. It had previously been entitled Network Management, and has been renamed to more accurately describe the purpose of the messages described herein. This chapter does not specify a protocol for managing networks, á la TCP/IP SNMP. Rather, its messages provide a means to manage HL7-supporting applications over a network.

Because this chapter was originally named "Network Management," the messages and segments have labels beginning with the letter "N." These labels are retained for backward compatibility.

As a technical chapter, this information is now normative with respect to the HL7 standard. It is anticipated that additional messages and message content will be added to this chapter in the near future.

28.3 Trigger Events and Message Definitions (14.3)

28.3.1 NMQ - Application Management Query Message (Event N01) (14.3.1)

28.3.1.1 Acknowledgement Choreography (14.3.1.0)

None - Refer to Chapter 5 for generic query choreography.

28.3.2 NMD - Application Management Data Message (Event N02) (14.3.2)

The N02 event signifies when an unsolicited update (UU) Application Management Data message (NMD) is created by on application to transmit application management information to other applications. In this case, the initiating application sends an NMD message as an unsolicited update (UU) containing application management information to a receiving application, which responds with a generic acknowledgement message (ACK).

For example, an application going down for backups (or starting up again after backups) might issue such a message to one or more other applications. An application switching to another CPU or file-server may also need to use this transaction to notify other systems.
