This file contains parameters used by the HLO (HL7 Optimized) that are specific to the system the software is installed on.
CROSS
REFERENCED BY: DOMAIN NAME(B)
779.1,.01 DOMAIN NAME 0;1 FREE TEXT (Required)
INPUT TRANSFORM: K:$L(X)>64!($L(X)<3)!'(X'?1P.E) X
LAST EDITED: AUG 05, 2004
HELP-PROMPT: The domain name for this system. It will be used to populate component 2 of the Sending Facility
field of the HL7 message header.
DESCRIPTION: The domain name for this system. It will be used to populate component 2 of the Sending Facility
field of the HL7 message headers.

2)= K ^HLD(779.1,"B",$E(X,1,60),DA)
779.1,.02 STATION NUMBER 0;2 FREE TEXT
INPUT TRANSFORM: K:$L(X)>7!($L(X)<3) X
LAST EDITED: AUG 05, 2004
HELP-PROMPT: Enter the station number with suffix that this system belongs under. It will be used in component
1 of the Sending Facility field of the HL7 message header.
779.1,.03 PRODUCTION ID 0;3 SET (Required)
'P' FOR production;
'T' FOR training;
LAST EDITED: AUG 05, 2004
HELP-PROMPT: ENTER P if this is a production system, T otherwise.
779.1,.04 MAXIMUM STRING LENGTH 0;4 NUMBER
INPUT TRANSFORM: K:+X'=X!(X>99999)!(X<1)!(X?.E1"."1N.N) X
LAST EDITED: JUL 06, 2005
HELP-PROMPT: This is the maximum length for strings built by HLO when local applications create new messages to
send.
DESCRIPTION: This parameter determines the maximum length for strings that HLO will create when messages are
being built. It doesn't apply to servers, as the size of input buffer used by TCP/IP determines
the maximum string length created by a single read.
779.1,.05 BUFFER SIZE FOR HL7 (BYTES) 0;5 NUMBER
INPUT TRANSFORM: K:+X'=X!(X>20000)!(X<10000)!(X?.E1"."1.N) X
LAST EDITED: AUG 05, 2005
HELP-PROMPT: This parameter represents the size of the buffer used by HLO for its background processes. It
defaults to 15000 bytes, but may be set from 10,000 bytes to 20,000 bytes.
779.1,.06 BUFFER SIZE FOR USER (BYTES) 0;6 NUMBER
INPUT TRANSFORM: K:+X'=X!(X>10000)!(X<512)!(X?.E1"."1.N) X
LAST EDITED: AUG 05, 2005
HELP-PROMPT: This parameter is the size of the buffer used by HLO in the context of an online user. It defaults
to 5000, but may be reset to between 512 and 10000 bytes.
779.1,.07 NORMAL MSG RETENTION (DAYS) 0;7 NUMBER
INPUT TRANSFORM: K:+X'=X!(X>99)!(X<1)!(X?.E1"."1.N) X
LAST EDITED: MAR 26, 2012
HELP-PROMPT: How many days should successful messages be kept before being purged? Enter a whole number, 1 to
99.
DESCRIPTION: This field controls how many days successful messages are retained after being fully processed
before they are purged.
The application may specify a longer time to retain its messages, which would override the time
specified here.
779.1,.08 BAD MESSAGE RETENTION (DAYS) 0;8 NUMBER
INPUT TRANSFORM: K:+X'=X!(X>99)!(X<5)!(X?.E1"."1.N) X
LAST EDITED: MAR 23, 2012
HELP-PROMPT: How many days should message with errors remain on your system? Enter 5 to 99. The default is 7.
DESCRIPTION: This field controls the purging of HL7 messages that do not complete successfully. The period
should be reasonably long to allow investigation, but because of the high daily volume of messages
purging must occur as quickly as practical.
779.1,.09 HLO ON/OFF SWITCH 0;9 SET
'0' FOR OFF;
'1' FOR ON;
LAST EDITED: MAY 03, 2005
HELP-PROMPT: Set to 0 to turn off messaging and all HL7 processes.
779.1,.1 HLO STANDARD LISTENER 0;10 POINTER TO HL LOGICAL LINK FILE (#870)
INPUT TRANSFORM: S DIC("S")="I ($P($G(^HLCS(870,Y,400)),""^"",3)=""M"")!($P($G(^HLCS(870,Y,400)),""^"",3)=""S"")" D
^DIC K DIC S DIC=$G(DIE),X=+Y K:Y<0 X
LAST EDITED: JUN 01, 2005
HELP-PROMPT: Select an entry from the HL Logical Link file that is the listener that remote applications will
normally connect to.
SCREEN: S DIC("S")="I ($P($G(^HLCS(870,Y,400)),""^"",3)=""M"")!($P($G(^HLCS(870,Y,400)),""^"",3)=""S"")"
EXPLANATION: This screen allows only server entries to be selected.
779.1,.11 HLO RECOUNT ON/OFF FLAG 0;11 SET
'0' FOR OFF;
'1' FOR ON;
LAST EDITED: OCT 25, 2007
HELP-PROMPT: Set to 1 to disallow update of queues when a recount is being performed.
779.1,.12 UNSENT MSG RETENTION (DAYS) 0;12 NUMBER
INPUT TRANSFORM: K:+X'=X!(X>999)!(X<1)!(X?.E1"."1.N) X
LAST EDITED: JUL 23, 2008
HELP-PROMPT: How many days should an unsent message be kept before it is purged? (default value is 45 days)
779.1,.13 BOX-VOLUME PAIR 0;13 POINTER TO TASKMAN SITE PARAMETERS FILE (#14.7)
LAST EDITED: MAR 24, 2010
HELP-PROMPT: Enter the BOX-VOLUME pair that HLO processes should run on.
DESCRIPTION: The BOX-VOLUME PAIR parameter allows a site to specify which CPU and volume set the HLO processes
should run on. This parameter only controls procesess started by the HLO Process Manager by
calling the Taskmanager APIs.
This parameter is optional.
For VMS sites, this parameter generally does NOT control what node to run the listener on, because
VMS sites should use VMS TCPIP Services for their listener.
For Cache/NT sites using a load balancer, this parameter can be used to specify what node to run
the listener on.
