#InterSystems Demo Games entry

This demo introduces an AI-powered clinical decision support tool built on InterSystems IRIS. The use case addresses clinician burnout by unlocking the wisdom trapped in 30,000 unstructured clinical notes. We showcase IRIS's powerful vector search to perform hybrid (semantic + keyword) queries for complex diagnostic challenges. The highlight is our multi-modal Retrieval-Augmented Generation (RAG) assistant, which analyzes clinical video content in real-time to find similar past cases and synthesize evidence-based recommendations, transforming how clinicians access and utilize institutional knowledge.

Hello community.

I have a request from a client who wants to do the following.
Currently, they have a data upload process via FTP in which they have implemented a RecordMap to store the information of the CSV files that are uploaded to the FTP directory.
Now they want to have another directory so that it is ONLY executed through an external instruction, not when the file is uploaded to the directory.

Hey folks! Having recently onboarded to InterSystems, I realized that despite having a totally free and awesome Community Edition, it's not super clear how to get it. I decided to write up a guide highlighting all the different ways you can access the Community Edition of InterSystems IRIS:

Get InterSystems IRIS Community Edition as a Container

Working with a containerized instance of the Community Edition is the recommended approach for folks who are new to developing on InterSystems IRIS, and in my opinion it's the most straightforward. InterSystems IRIS Community Edition can be found on DockerHub; if you have an InterSystems SSO account, you can also find it in the InterSystems Container Registry.

In either case, you'll want to pull the image you want using the docker CLI:

docker pull intersystems/iris-community:latest-em
// or
docker pull containers.intersystems.com/intersystems/iris-community:latest-em

Next, you'll need to start the container: In order to interact with IRIS from outside the container (for example, to use the management portal) you'll need to publish some ports. The following command will run the IRIS Community Edition container with the superserver and web server ports published; note that you can't have anything else running that depends on ports 1972 or 52773!

docker run --name iris -d --publish 1972:1972 --publish 52773:52773 intersystems/iris-community:latest-em

Hi

I am trying to help another group within our organization access a SQL Table that I have created to populate Epic Department Data within our environment and came across the ability to use SQL Seach REST Interface using iKnow.

However, I am having issues trying to get it to work via POSTMAN before I hand off the solution...

the POST URL... https://<servername>/api/iKnow/latest/TESTCLIN/table/osuwmc_Epic_Clarity.DepartmentMaster/search

where osuwmc_Epic_Clarity.DepartmentMaster is the table

In the body...

We have a task that runs objectscript code to load data into a linked external table. After upgrading from 2024.1 to 2025.1, the load is throwing an error, with error code -400, and no error message. The data DOES get loaded into the external table in its entirety, so with no meaningful error message, its hard to determine what the issue is. The result is the same with and without the USING clause, so don't let that confuse you. We have logs of this statement succeeding before upgrade, and were able to get this statement to work in our production environment, which is still on version 2

In InterSystems IRIS, you can create linked tables using commands, instead of using System Explorer > SQL > Wizard > Linked Tables in the Management Portal:

Hi folks!

Sometimes, when designing a class method and feeding it with more and more useful features, very soon the number of parameters can reach 10 and even more.

It becomes pretty difficult for users of useful methods to remember the position of the important parameter, and it is very easy to misuse the position and transfer the wrong value to the wrong parameter.

Here is an example of such a method (I asked GPT to create a method with 20 params):

ClassMethod GenerateReportWith20Params(
    pTitle As %String = "",
    pAuthor As %String = "",
    pDate As %String = "",            // e.g. 2025-09-03
    pCompany As %String = "",
    pDepartment As %String = "",
    pVersion As %String = "1.0",
    pFormat As %String = "pdf",       // pdf|html|docx
    pIncludeCharts As %Boolean = 1,
    pIncludeSummary As %Boolean = 1,
    pIncludeAppendix As %Boolean = 0,
    pConfidentiality As %String = "Public",
    pLanguage As %String = "en",
    pReviewers As %String = "",       // CSV, e.g. "Alice,Bob"
    pApprover As %String = "",
    pLogoPath As %String = "",
    pWatermarkText As %String = "",
    pColorScheme As %String = "default",
    pPageSize As %String = "A4",
    pOrientation As %String = "Portrait",
    pOutputPath As %String = "report.pdf"
) As %Status
{

// implementation
}

This might be a dumb question but can we have more than one production in a namespace, because we do have running but I thought that I could create a separate one for another project?

Thx

Getting this error when create a class in IRIS, any clues?

Thanks

Managing InterSystems Servers – In-Person September 29-October 3, 2025

InterSystems IRIS interoperability production development involves using or writing various types of components. They include services (which handle incoming data), processes (which deal with the data flow and logic), and operations (which manage outgoing data or requests).

I have defined a class with a dynamic object property:

Class test.Dyn Extends %Persistent
{

Property json As %DynamicObject;

/// do ##class(test.Dyn).test()
ClassMethod test()
{
  do ..%KillExtent()
  for len = 100, $$$MaxStringLength - 1, $$$MaxStringLength, $$$MaxStringLength+1, $$$MaxStringLength *2 {
    set sc = ..save(len)
    write "Len: ",len, " Result: ",$case($$$ISERR(sc), $$$YES: $System.Status.GetErrorText(sc), : "OK"),!
  }
}

ClassMethod save(len)
{
  set json = {}
  set stream = ..getStream(len-8) // -8 because {"a":""}
  do json.%Set("a", stream, "stream")
 
  set obj = ..%New()
  set obj.json = json
  quit obj.%Save()
}

ClassMethod getStream(len)
{
  set stream = ##class(%Stream.TmpCharacter).%New()
 
  if len<$$$MaxStringLength {
    do stream.Write($tr($j("",len)," ","A"))
  } else {
    for i=1:$$$MaxStringLength:len {
      do stream.Write($tr($j("",$$$MaxStringLength)," ","A"))
    }
    do stream.Write($tr($j("",len-i)," ","A"))
  }
  quit stream
}
}

The issue I encounter is that if a length of a serialized json property is more than 3641144 symbols, the object fails to save with the following error (either MAXSTRING or STRINGSTACK):

Length: 100 Result: OK
Length: 3641143 Result: OK
Length: 3641144 Result: OK
Length: 3641145 Result: ERROR #5002: ObjectScript error: <MAXSTRING>%GetSerial+1^%Library.DynamicAbstractObject.1
Length: 7282288 Result: ERROR #5002: ObjectScript error: <STRINGSTACK>%GetSerial+1^%Library.DynamicAbstractObject.1

Is there a workaround? I need to store moderately large jsons (10-15 Mb) and dynamic object properties allow for a very convenient access.

$ZSTORAGE is set to -1.

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.
