Hey Community,

We're excited to invite you to the next InterSystems UKI Tech Talk webinar: 

👉SQL Cloud Services

⏱ Date & Time: Thursday, April 24, 2025 14.30-15.30 UK

👨‍🏫 Speaker: @Kinshuk Rakshith, Sales Engineer, InterSystems

I have written a new script for csv file export, which writes lines to a %Library.File file based on a SQL query.

The code is simplified into the following as 

try {
    // set up file as %Libary.File
    set f = ##class(%Library.File).%New()
    set f.Name = "export.csv"
    if (##class(%File).Exists(f.Name)) { $$$ThrowOnError(##class(%File).Delete(f.Name)) }
    $$$ThrowOnError(f.Open("WUN"))
    $$$ThrowOnError(f.

Hi all,

I noticed today that when adding a namespace (localhost) to the Workplace in VS Code, it is being created as read-only.

I haven’t encountered this issue before - previously, I was able to add the namespace with full access and could edit files without any problems. The settings appear to be the same as before.

Interested in sharing your thoughts? Sign up to participate here.

I know that people who are completely new to VS Code, Git, Docker, FHIR, and other tools can sometimes struggle with setting up the environment. So I decided to write an article that walks through the entire setup process step by step to make it easier to get started.

I’d really appreciate it if you could leave a comment at the end - let me know if the instructions were clear, if anything was missing, or if there’s anything else you'd find helpful.

The setup includes:

✅ VS Code – Code editor
✅ Git – Version control system
✅ Docker – Runs an instance of IRIS for Health Community
✅ VS Code REST Client Extension – For running FHIR API queries
✅ Python – For writing FHIR-based scripts
✅ Jupyter Notebooks – For AI and FHIR assignments

Before you begin: Ensure you have administrator privileges on your system.

In addition to reading the guide, you can also follow the steps in the videos:

For Windows

If you look at the values.yaml of the IKO's Helm chart you'll find:

useIrisFsGroup: false 

Let's break down what it is and in what situations you may want to set it to true.

FsGroup refers to the file system group.

By default, Kubernetes volumes are owned by root, but we need IRIS to own its files (IRIS in containers is installed under irisowner user). To get around this we employ one of two methods:

1) initContainers

The initContainers run before app containers (like IRIS) in a pod. They generally set up the environment for the application and then run to completion/terminate.

There is a list of numbers from 1 to 190.

AllList="1,2,3,4,5,6,7,8,9,.....,187,188,189,190"

There is a collection of sets of these values:

List(1)="3,5,6,7,9"
List(2)="1,2,6,9"
List(3)="5,8,9"
List(4)="2,4,6,8"
List(5)="4,7,9"

What is an elegant approach in Object Script to pick the least number of list items:

• List(1)
• List(5)
• List(n)

That together would cover as many numbers as possible from the AllList.

Interested in best coverage over efficiency.

Hello Team,

I got xDBC protocol is not compatible while executing python script. How to fix this error

Hello 

We are pretty new to Ensemble and we are considering on using a default setup for our production. Let me explain the situation. We have one sender that sends HL7 ADT messages to our system. We have 60+ other systems that need to recieve ADT messages. We where thinking on a few ways on how to do the setup. 

Setup1:

We create one big ADTRouter that contains a first mapping. The result is send to another big ADTRouter that contains all the filters/expressions and mappings for the recieving systems.

Hi everyone,

I'm working on a DTL that transforms an HL7 message (EnsLib.HL7.Message) to an XML document (EnsLib.EDI.XML.Document).

The target XML is based on a custom schema and has an element like:

What I need is for the output to show:

<deceasedDateTime xsi:nil="true"/> when the source HL7 value is empty, for eg: 

<portalPatientUpdate xmlns:xsi="http://www.w3.

Hello,

Our software commonly returns a full result set to the client and we use the DataTables plugin to display table data.  This has worked well, but at datasets grow larger, we are trying to move some of these requests server-side so the server handles the bulk of the work rather than the client.  This has had me scratching my head in so many ways.  

I'm hoping I can get a mix of general best practice advice but also maybe some IRIS specific ideas.

Using Cache 2017.2 sever as my target.

I have a x64 Ubuntu client setup going.  This is NOT server. Just client. 

I have the Linux Ubuntu x64 ODBC driver gzip file. 

ODBC-2018.1.5.659.0-lnxubuntux64.tar.gz is all I could find.  Someone posted it in another post.

I can connect to a test sever that does NOT use SSL.  That works pretty easily.

But I have A server with SSL enabled. With Windows Cache ODBC drivers I can use SSL just fine.

This is what my SSLDefs.ini file on the Windows machines look like and it works just fine.

YES. I know. Not super secure because of the settings.

I ask ChatGPT periodically to produce ObjectScript or plain MUMPS code for string manipulation, or for implementing known algorithms etc. Occasionally, it does make mistakes or uses non-existing class members but generally not that bad. Is there any tutorial on the subject of using AI for coding, ideally specifically for ObjectScript/MUMPS? Any AI productivity advice, or tricks you are using, or another AI flavor?

Thanks in advance,
Anna

Hello Community,

The subroutine ^routine is not executed while the queue is being processed in WorkMgr. However, it works when defined as a function. Is it mandatory to define subroutine^routine as a function for it to execute properly?

testwqm.mac
 set wqm = ##class(%SYSTEM.WorkMgr).%New()
 set sc=wqm.Queue("subr1^testwqm")  ; not executing the subr1 
 set sc=wqm.Queue("subr2^testwqm") ; executing the subr2 properly
 set sc=wqm.

⏯ Integrating DBT and Apache Airflow with InterSystems IRIS @ Global Summit 2024

Hey everyone.

I'm currently looking at a process where we're utilising the Class Ens.StreamContainer, and was looking to do some deletions outside of any purge routines.

Having been burned before, I wanted to make sure that deleting the container also deletes the contents within.

From looking in the class, the  %OnDelete ClassMethod appears to be removing an index from a search table and nothing more.

Am I looking in the right place, or is there a extended class for Ens.StreamContainer that does in fact delete the %Stream.Object
contained within the Ens.StreamContainer?

Hi everyone,

I'm currently testing out IRIS 2024.3 for a new project, and it's been running smooth for the most part. However, I noticed that when running some heavier analytical queries, the memory usage spikes more than I expected, even when result sets aren’t that large.

I’ve gone through the basics (buffer sizes, query plans, etc.), but I’m wondering if there are any new tweaks or recommended settings in 2024.3 specifically for managing memory better during these peak loads.

Anyone else run into something similar or have tips to fine-tune this?

Thanks for any help!
 

Background

Embeddings is a new IRIS feature empowering the latest capability in AI semantic search.
This presents as a new kind of column on a table that holds vector data.
The embedding column supports search for another existing column of the same table.
As records are added or updated to the table, the supported column is passed through an AI model and the semantic signature is returned.
This signature information is stored as the vector for future search comparison.
Subsequently when search runs, a comparison of the stored signatures occurs without any further AI model processing overhead.
