Field #	Name	Loc	Type	Details
.01	DOMAIN NAME	0;1	FREE TEXT	**********************REQUIRED FIELD********************** 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. CROSS-REFERENCE: `779.1^B` 1)= S ^HLD(779.1,"B",$E(X,1,60),DA)="" 2)= K ^HLD(779.1,"B",$E(X,1,60),DA)
.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.`
.03	PRODUCTION ID	0;3	SET	**********************REQUIRED FIELD********************** 'P' FOR production; 'T' FOR training; LAST EDITED: `AUG 05, 2004` HELP-PROMPT: `ENTER P if this is a production system, T otherwise.`
.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.
.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.`
.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.`
.07	NORMAL MSG RETENTION (HOURS)	0;7	NUMBER	INPUT TRANSFORM: `K:+X'=X!(X>96)!(X<36)!(X?.E1"."1.N) X` LAST EDITED: `MAR 17, 2005` HELP-PROMPT: `How many hours should successfully completed messages remain on your system? (36-96 hours, defaults to 36 hours)` DESCRIPTION: `This field controls the purging of HL7 messages whose completion status is SUCCESSFUL. It is in hours, since messages normally should be purged very soon after completion, with an allowed range of 36 to 94 hours.` 36 is the default because this 1) will result in most messages being purged at night and 2) provides sufficient time for the Capacity Planning statistics to be extracted.
.08	BAD MESSAGE RETENTION (DAYS)	0;8	NUMBER	INPUT TRANSFORM: `K:+X'=X!(X>45)!(X<5)!(X?.E1"."1.N) X` LAST EDITED: `NOV 15, 2004` HELP-PROMPT: `How many days should message with errors remain on your system? (7-45 days, defaults to 7 days)` 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 extremely high daily volume of messages purging must occur` quickly.
.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.`
.1	HLO STANDARD LISTENER	0;10	POINTER TO HL LOGICAL LINK FILE (#870)	HL LOGICAL LINK(#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.`
