introduced in Kernel patch XU*8*142. One or more IP addresses may be
registered on the DNS systems. The DNS was initially seeded with IP
information supplied by HL*1.6*39 and any subsequent changes made to date
to the VA* and MPI logical links. These IP addresses are associated
specifically with the service "HL7" on the DNS and the port 5000. The port
number is currently fixed for HL7 and should not be changed. If only one
IP address is returned, it will be stored in the site's local Logical Link
file and used for subsequent connections. If more than one IP is returned,
message exchange between sites using TCP, the TCP/IP address of each site
each address will be tried in sequence until a successful connection is
made. The successful IP address will then be stored and used until the
next connection attempt that fails.
Queries to the DNS will work only if the Logical Link (file 870) points to
the correct Domain (file 4.2). Review the link definitions paying
particular attention to those links in your VISN and verify that the
Domain field is defined correctly.
The Logical Link that represents your site should be configured as a

"multithreaded listener" to receive INBOUND connection requests. The IP
address and port for this listener is known by all other sites and
referenced by them to establish a connection. Changing the IP address will
prevent sites from establishing a connection. Therefore, if you wish to
establish a new IP address, your VA DNS must be updated in advance of the
change. It must contain an entry in the format, HL7.yoursite.domain.ext,
and your new TCP/IP address. For example, DNS will contain an entry for
Bay Pines VA looking like, "HL7.BAY-PINES.DOMAIN.EXT." This entry will
return a TCP/IP address of 152.130.80.5.

Please note that the HL7 development team is not involved with maintenance
of the VA's DNS systems. Questions should be refered to your local or
VISN-level DNS administrator, or via MS Exchange to the group, "VHA CIO

Following the installation of this patch you should enable your TCP/IP
listener for inbound HL7 connections. Detailed instructions for this may
be found in the HL7 Document, "Vista HL7 Site Manager and Developer
Manual" released as HL*1.6*56. Here, you will find information for both

Installation Instructions:
==========================
1. Users are allowed to be on the system during the installation.
"discover" this information without interruption in message exchange.
2. DSM SITES: Review your mapped set. If any of the routines listed
in the Routine Summary section are mapped, they should be removed
from the mapped set at this time.
3. Shutdown all Logical Links and incoming and outgoing filers, and
the Link Manager. Use the options:
Filer and Link Management Options ->
SA Stop All Messaging Background Processes
LM TCP/IP Link Manager Start/Stop
4. Use the 'INSTALL/CHECK MESSAGE' option on the PackMan menu. This
option will load the KIDS package onto your system.
5. The patch has now been loaded into a Transport global on your
system. You now need to use KIDS to install the Transport global.
On the KIDS menu, under the 'Installation' menu, use the following
options:
2 Verify Checksums in Transport Global
When a connection attempt over a TCP Logical Link fails, a call will be
3 Print Transport Global
4 Compare Transport Global to Current System
5 Backup a Transport Global
