Hello,
I am currently facing the task of retrieving or sending HL7 messages from a web API. Since we only send HL7 messages via internal sockets, web APIs are relatively new to me.
The following is my plan for the new interface:
I have created a new custom business service that periodically sends requests to a business process. In this business process, the HTTP request (HTTP.GenericMessage) is then created from scratch. The special feature is the "Authorisation" header field, where a signature is inserted, which consists of a base64-encoded hash value.

InterSystems ObjectScript extension for VS Code, version 3.0.1

Am also asking this question on the extension's GitHub page: Request textDocument/documentSymbol failed. Error: name must not be falsy · intersystems-community/vscode-objectscript · Discussion #1530 - but suspect more eyes will see it here, which might help gather additional information.

Tried to compile some legacy ObjectScript code via Import/Compile in VS Code using the vscode-objectscript extension. Getting an error, and the content of the file is left changed on the filesystem simply by being compiled.

In Ensemble->Enterprise Portal->Message Bank Viewer ,the Search option based on basic or extended criteria is not working.Please can somebody answer why so?

Hi,

I’m working in Ensemble and trying to resend a message from the Message Viewer. The message is in XML format.

When I try to edit the XML before resending,

• I open the message in the Message Viewer.
• I click Resend or Edit & Resend.

I’m looking for guidance on:

1. How to make a message editable in Message Viewer.
2. The proper way to modify an XML message before resending in Ensemble/IRIS.

Any suggestions or examples would be very helpful.

Hi all,
Recently we were experimenting with having a variable target on a routing rule and noticed some interesting behaviour, code below.

<rulename<</<

This code compiles and works. If SendingFacility is "TOM" the message will rout to ToTOMFromServiceTCPOpr, and if it is "BOB" it will route to ToBOBFromServiceTCPOpr.
However - if we remove the space between the first " and the first underscore as in below this rule will not compile with error

Invalid target name: To"_(pContext.Document.GetValueAt("MSH:SendingFacility"))_"FromServiceTCPOpr. Target name should not contain "_ and _"

Overview

This web interface is designed to facilitate the management of Data Lookup Tables via a user-friendly web page. It is particularly useful when your lookup table values are large, dynamic, and frequently changing. By granting end-users controlled access to this web interface (read, write, and delete permissions limited to this page), they can efficiently manage lookup table data according to their needs.

The data managed through this interface can be seamlessly utilized in HealthConnect rules or data transformations, eliminating the need for constant manual monitoring and management of the lookup tables and thereby saving significant time.

Note:
If the standard Data Lookup Table does not meet your mapping requirements, you can create a custom table and adapt this web interface along with its supporting class with minimal modifications. Sample class code is available upon request.

I'm trying to make a connection to an external database using %SQLGatewayConnection, but the connection always fails. DSN properly configured. I try to make the same connection through isql in bash, and the connection is successful.

This same connection fails in Caché.

Some languages ​​have the concept of a garbage collector for automatic memory management. I'd like to know if something like this exists in InterSystems Caché in the context of routines, %CSP.REST, or %CSP.Page.

The question arises from the %Close() method of the %RegisteredObject class. This indicates that I need to manually clear the object from memory if it's no longer in use, or in the web context, if the request has completed. Is this correct? Or am I completely wrong?

Thank you!

To manage the accumulation of production data, InterSystems IRIS enables users to manage the database size by periodically purging the data. This purge can apply to messages, logs, business processes, and managed alerts.

Please check the documentation for more details on the settings of the purge task:
https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=EGMG_purge#EGMG_purge_settings

An issue that many users ran into is still finding old messages after running the purge task for messages. For example, a user has a purge task for messages that has NumberOfDaysToKeep=45.

This code provide the configured production items with enabled or disabled status.

Include (Ensemble, EnsUI, EnsUtil)

Class Test.ProductionConfig
{

ClassMethod GetConfigItems() As %Status
{
Set tStatement = ##class(%SQL.Statement).%New()
Set tSC = tStatement.%PrepareClassQuery("Ens.Config.Production","EnumerateConfigItems")
Write tSC,!
Write "ConfigItemName"," ","Enabled",!
#Dim exp As %Exception.SystemException
#Dim rset As %SQL.StatementResult
Set rset = tStatement.%Execute()
Write rset,!
Write rset.%SQLCODE,!
While rset.%Next() {
Try {
Set tConfigName = rset.%GetData(1)
Set tEnabled = rset.

For historic reasons we've got a mix of ADT feeds coming out of our PAS (TrakCare) to a wide range of downstream systems. In particular, there are some that are direct from TrakCare to the downstream systems, and many more that pass through Ensemble as our integration engine.

This is complicating management of the integrations, and so we'd like everything to go through the integration engine.

The ^%GCMP utility can be used to compare the contents of two globals.

For example, to compare ^test and ^test in the USER and SAMPLES namespaces, it would look like this:
*In the example below, 700 identical globals are created in the two namespaces, and the contents of one of them is changed to make it the detection target.

Introduction

HL7 messages often contain multiple repeating segments such as NTE, AL1, OBX, ZTX, DG1, and others. These segments sometimes require individual processing and routing to different downstream systems. This technical paper introduces a configurable template designed to automate the splitting of these repeating HL7 segments, improving message handling and integration efficiency.

The utility returns the desired values from the text and display the multiple values if exists based on starting and ending string.

Class Test.Utility.FunctionSet Extends %RegisteredObject

One way to optimize query performance is to use query parallelism on a per-query or system-wide basis (a standard feature).

This is a technique for dividing the execution of a particular query among processors on a multi-processor system. The query optimizer will execute parallel processing only if there is a possibility of benefiting from parallel processing. Parallel processing is only applicable to SELECT statements.

Note that the number of parallel processes cannot be specified, as it is automatically adjusted according to the number of CPUs.

Our vendor is developing an interface API on their end to capture HL7 data on a Server Port, and they require us to send a pre-defined HL7 Order message for testing every hour until the API is completely operational.

Is it possible to accomplish that in a Business Operation automatically without utilizing a service or process? The BO is a standard TCP/IP connection.

I'm manually sending the message again from the Operations right now. I do not have access to the System Operation to use the Task Manager feature.

Hi Team,

I've basic learning in Ensemble. I want to create a code as per following request. Please help in clearing following questions

We have a business process-AA. In this business process, we have onRequest method, here after performing some logic, I have to call a method ProcessAAlogic. 

In ProcessAAlogic method, after initial processing, we have to call a business operation BB asynchronously (which will give a flag "AACompleted" having value 1 or 0) in pResponse object.
Now based on this AACompleted flag, I have to call other methods which are part of onRequest method  i.e.

We are trying to make an ODBC connection via our intersystems ensemble (2016.2 running on ubuntu). However, when I am testing the connection I receive a pop-up that: "Http object response incomplete or invalid.0,#R". Note that the iodbctrace.log remains empty (and it is working because on the first try it registered a 459 error that I should activate kerberos, which I did). Any advise where I should look?
I have taken the following actions:

1. Expand the cacheodbc.

Actually, I want to know specific production component status. I used "Ens.Config.Production" to get the status of component. But it will return only the component enabled/disabled. Anyone is having any Idea to get the specific production component status?

I have a vendor that only wants results on patients that arrive to the ED via EMS/Ambulance.  The value I need for filtering is in the PV2;38. Some of the results requested do not allow the PV2 segment to be added to the schema in the EMR.  I was told that other orgs have used a lookup table that is populated with the PV1;19 value when an ADT messages that meets the criteria is sent in.  This table is then referenced in the business rule for the results that do not have PV2;38 and if Encounter number from result message exists on the Table, the result is sent.  Has anyone done this before?

I have been walking through this with a few team members and as such I thought there might be others out there who could use it, especially if you work with HL7 & Ensemble/HealthConnect/HealthShare and never venture out past the Interoperability section. 

First, I would like to establish that this is an extension of the already established documentation on importing and exporting SQL data found here: https://docs.intersystems.com/iris20241/csp/docbook/DocBook.UI.Page.cls?KEY=GSQL_impexp#GSQL_impexp_import

Mirroring only synchronizes database files.

To synchronize other files required for your application (CSP files, images, documents, etc.) between the two servers that make up the mirror set follow one of the approaches:

1. Place those files on a shared disk by introducing a NAS or similar device
2. Or use file sync software to synchronize files between two servers.

Dear, Community!

I have a concern about using %Stream.TmpCharacter for storage purposes. Reading the class's source code, I can understand a bit about how it works. But I'd like to know from the community how it actually works. Is it necessary to use the .Clear() method to clear this buffer, or is it done automatically upon disposal?

Note: Please forgive my poor English.

Studio's Find In Files finds nothing if CLS routines are included. The error is WIDE CHAR. After using ##class(%Studio.Project).FindInFiles programmatically and then ZW after the same error I strongly suspect that CodeWalkopdatecopyopt in EnsLib.InteropTools.HL7.Cloverleaf.Parser.cls  is to blame. I cannot even open this class, unlike other classes from EnsLib.InteropTools.HL7. This error prevents searching even if System Items are excluded and I would peg EnsLib as System. Any remedy besides updating IRIS? Assuming this is fixed in later IRIS versions.

Hello,

I'm trying to get the Reply Action Code to work with the error message text.

I have this ACK:

MSH|^~\&|APP|FACIL|||20250821143621||ACK|CUEACK_20250821143621|P|2.4
MSA|AE||Failed to queue message

This is some of the Action Codes I've tried:

• E*Failed to queue message=S
• E*Failed=S
• E*"Failed to queue message"=S
• :E*Failed to queue message=S
• :?E*Failed to queue message=S

It's not suspending the message however.

What am I doing wrong?

Thank you

Like %GlobalCharacterStream, %GlobalBinaryStream, and others, as been deprecated in favor of %Stream.GlobalCharacter, %Stream.GlobalBinary, will this deprecated libraries one day no longer work?

If you’ve ever watched a true artisan—whether a potter turning mud into a masterpiece or a luthier bringing raw wood to life as a marvelous guitar—you know that magic isn’t in the materials, but in care, craft, and process. I know this firsthand: my handmade electric guitar is a daily inspiration, but I’ll admit—creating something like that is a talent I don’t have.

Yet, in the digital world, I often see people hoping for “magic” from generative AI by typing vague, context-free prompts like “build an app.” The results are usually frustratingly shallow—no artistry, no finesse.
