description

This file is used to register sending and receiving applications for HL7 messaging. For receiving applications, the process of registration consists of registering what messages the application is prepared to receive. For both sending and receiving applications, it is necessary to specify what package the application belongs to. For sending applications, that is the only field that applies, other than the name of the sending application. An application can be either a sender or a receiver of messages, or both. In order for an application to receive messages, it must specify an action (M tag^routine) for each type of message that it is capable of receiving, or a default action that applies when no messsage-specific action is defined.

Fields

#	Name	Location	Type	Details	Index	Description
.01	application name(+)	0;1	FREE TEXT		B
.02	response link (optional)	0;2	FREE TEXT			This field applies only if: 1) The receiving application is expected to return application acknowledgments. 2) The initial message is received indirectly through the IE, and the receiving application in turn does not want to send the application acknowledgment directly back to the sending facility identified in the message header.
.03	default private in-queue	0;3	FREE TEXT
.04	batch action tag	0;4	FREE TEXT
.05	batch action routine	0;5	FREE TEXT
.06	default action tag	0;6	FREE TEXT
.07	default action routine	0;7	FREE TEXT
.08	batch private in-queue	0;8	FREE TEXT
.09	application specific listener	0;9	POINTER	870		Applications are highly discouraged from establishing their own listeners. The use of the multi-listeners provide concurrent processing of many connections over the same port, so a dedicated listener will not provide an application with a performance boost, while it will cause the site additional work to maintain. So before establishing a dedicated listener, the application developer should verify the need.
.1	sequence exception tag	0;10	FREE TEXT
.11	sequence exception routine	0;11	FREE TEXT
.12	sequencing timeout	0;12	NUMERIC
.13	minimum retention time	0;13	NUMERIC			This field may be used by the application to set the minimum number of days that its messages should be retained after being processed. This value applies to the application's messages as a whole, but may be overridden if the application specifies a value for specific message types. The site parameter, if set to a longer time, will override the application parameter, whereas a shorter value will be ignored.
1	message type actions	1;0	MULTIPLE	779.21
2	package file link(+)	2;1	POINTER	9.4		This field holds a pointer to the Package File for the Package responsible for these messages.
