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.

I had a need for a Filter, but did not want to recreate the wheel by creating another Data Lookup Table, so instead I created a Linked Table that points to a MS SQL Table outside of IRIS.

Once I had the Linked Table, I created a Class Method Function that would query the Linked Table and return a 1 if a result came back.

IAM - InterSystems API Manager is a great tool for monitoring your traffic. If you are trying to use it in your Kubernetes cluster you may have tried doing a deployment similar to this one:

Hi folks!

It is very easy to import CSV data into IRIS. But what if we want to preserve the original IDs in CSV?

Recently I came across with the situation when I needed to import two csv's into IRIS which were linked by one column referencing to another csv's col: a typical Foreign Key and Primary Key situation, where csv1 contains this column as Primary Key, and csv2 as Foreign key with id's related to csv1.

The image is generated by ChatGPT so don't blame it - it tried its best to generate countries as primary keys with countries.csv-cities.csv relationship :)

Trying to import a .csp with VS code appears to do nothing.

Making a change to the file, saving it and then doing "Import and compile" results in no output and there is no change to the file on the server.

Plugin version is 3.0.5

I’m pleased to announce the release of tree-sitter-objectscript, a new open-source tree-sitter grammar that brings first-class ObjectScript support to modern editors. If you caught the preview at READY ’25, you’ll be glad to know it’s now up on Github:

In this case, a robot is nothing like Gort from the movie “The Day the Earth Stood Still” or any other humanoid robot from science fiction. Nor is this Robot the one-armed automated welder from a real-world automotive assembly line. This Robot is a program that controls another program. You might want this for automated testing or to capture application logic from an application for which you don’t have the source, and the application’s author lacked the kindness or foresight to provide an API for its capabilities.

⏯️ Closing the Scientific Knowledge Gap with AI

For venture capitalists (VCs), evaluating research can be challenging. While researchers typically possess years of training and deep expertise in their field, the VCs tasked with assessing their work often lack domain-specific knowledge. This can lead to incomplete understanding of scientific data and an inability to direct organizational initiatives. To solve this problem, we have designed a solution that empowers VCs with AI-driven due diligence: ResearchExplorer. ResearchExplorer is powered by InterSystems IRIS and GPT-4o to help analyze private biomedical research alongside public sources like PubMed using Retrieval-Augmented Generation (RAG). Users submit natural language queries, and the system returns structured insights, head-to-head research comparisons, and AI-generated summaries. This allows users to bridge expertise gaps while securely protecting proprietary data.

I would like to know which are the best practices of using Streams in Interoperability messages.

I have always use %Stream.GlobalCharacter properties to hold a JSON, or a base64 document, when creating messages. This is fine and I can see the content in Visual Trace without doing anything, so I can check what is happening and resolve issues if I have, or reprocess messages if something went wrong, because I have the content.
