Since the introduction of Embedded Python there has always been doubt about its performance compared to ObjectScript and on more than one occasion I have discussed this with @Guillaume Rongier , well, taking advantage of the fact that I was making a small application to capture data from public competitions in Spain and to be able to perform searches using the capabilities of VectorSearch I saw the opportunity to carry out a small test.

Using %get() function, getting error <INVALID OREF>

set iter = identifiers.%GetIterator()
     while iter.%GetNext(.key, .value, .type ) {
        set type = value.%Get("type")
        set text = type.%Get("text")
 

getting <INVALID OREF> at line   set text = type.%Get("text")

How  

Hi,

I want to get the status of a Production (Running, Stopped), Queue length, Time the Production started

I did this:

>zn "test"
>set status=##class(Ens.Director).GetProductionSummary(.pinfo)
>write status
1
>zwrite pinfo
pinfo("PKG.FoundationProduction")=$lb("Stopped","","",0)
pinfo("Report.Print.EnsemblePrintService")=$lb("Stopped","2021-02-09 23:15:57.538","2021-02-09 23:16:15.264",0)
pinfo("TC.hmf.Production")=$lb("Stopped","","",0)
pinfo("TC.hmf.System.Production")=$lb("Running","2025-10-30 10:18:24.

Hello word!

I am new in this field and i am coming from the dot net and angular world.
So hello to everyone!

Im trying to understand the unit test in the vs code what is works in the community version at home (25.2).
I set the  ^UnitTestRoot to somewhere and setted the "unitest: enabled" setting in the settings.json file. 
But it is not work and can't run. Is't it scan? It is not a problem because i can run it dircetley with ##class(classname).RunTest() and it runs but doesn't contain anyting. The Restresult is exist but it is empty.

Hi,

When we open a terminal in IRIS, we are entering the ObjectScript shell. Within this shell, we can execute IRIS commands, such as:

In other words, the ObjectScript command is executed in the current shell. But it's always good to remember that IRIS has other shells

• SQL
• Python
• TSQL
• MDX

One very interesting aspect is shortcuts. We can access these shells through their calls or via shortcuts, as shown in the table below:

Terminal Commands for Production:

• Production Start, Stop, Update, Recover and Clean Production

Do ##class(Ens.Director).StartProduction(“ProductionName”)

Do ##class(Ens.Director).StopProduction()

Do ##class(Ens.Director).UpdateProduction()

Do ##class(Ens.Director).RecoverProduction()

Do ##class(Ens.Director).CleanProduction()

Abort Messages in the queue:

               d ##class(Ens.Queue).AbortQueue(“Component Name”)

Get InstanceName :

              W !,##class(%SYS.System).GetUniqueInstanceName()

Get Node Name:

              W  !,##class(%SYS.System).GetNodeName()

Terminate JobId :

   d $SYSTEM.

Hola amigo! 😊 Cómo estás hoy,

I would like to share a small part of my learnings from my first ever official project: POS/EDC machine integration with our billing system. This was an exciting challenge where I got hands-on experience working with APIs and vendors. 

How does a Payment Machine actually work?

It's simple, start by initiating/creating a transaction, then retrieve its payment status.

Here, initiate/create refers to POST method and Retrieve refers to GET.

Hi developers!

How do you debug implementation code in .impl classes of REST.API in InterSystems IRIS?

Especially if you don't have access to globals, so no things like: 

Set ^AAA="here we are"

not possible in this case.

Suppose I have the following signature of the REST.API method called as POST and containing JSON. :

i am looking for a Class or Function to check if a Base64 document is valid ( will results into Full file after decoding or not ), 
i was not able to find any predefined class in Objectscript ,
has anyone worked on something  similar before ?
any advice will be welcomed 

When using a EnsLib.RecordMap.Service.FileService business service, is there a way to tell which row number that is being read in? I want to read in a csv, but on the first record, trigger a truncate on the External SQL Table that it is being written to through JDBC.

Thanks

Scott

As a developer who uses Cache as DB for a couple of projects, I'm using REST API's every time, knowing how to consume a resource from REST API, in my opinion, it's crucial to know how to consume external REST Api's using %Net.HttpRequest because it enables integration with modern web applications and services, and it's a crucial skill for a backend developer who loves and uses Cache as a DB.

What and who is %Net.

What is XML?

XML (eXtensible Markup Language) is a flexible, text-based, and platform-independent format used to store and transport data in a well-structured way that is both human- and machine-readable. XML permits users to define custom tags to describe the meaning and organization of their data. For example: <book><title>The Hitchhiker's Guide</title></book>.

An XML document is self-descriptive and structured as a hierarchical tree of elements. Every document has a single root element that encapsulates all other content.

Over time, while I was working with Interoperability on the IRIS Data Platform, I developed rules for organizing a project code into packages and classes. That is what is called a Naming Convention, usually. In this topic, I want to organize and share these rules. I hope it can be helpful for somebody.

Disclaimer: This guide is a good fit for Interoperability projects. When you have integrations, data flows, when you use IRIS for ETL processes, etc. Overall, when your code is combined with Productions.

I am looking to view the contents of the request object I am sending from my Service into my BPL in Message Viewer. My request contains references to other defined classes.

Class bd.webapp.OutboundMessageRequest Extends (%Persistent, Ens.Request)
{

Property Metadata As bd.webapp.OutboundMessageRequestMetadata;
Property MessageContent As %DynamicObject;
}



Class bd.webapp.OutboundMessageRequestMetadata Extends (%RegisteredObject, %JSON.

$System.Util.GetEnviron("USERPROFILE") returns "C:\WINDOWS\system32\config\systemprofile". I don't know what that is, but that folder doesn't even exist. The correct value which I need is "C:\Users\robert.steed", as seen via the Windows command line "set" command.

If you start with InterSystems ObjectScript, you will meet the XECUTE command.
And beginners may ask: Where and Why may I need to use this ?

The official documentation has a rich collection of code snippets. No practical case.
Just recently, I met a use case that I'd like to share with you.

The scenario:

When you build an IRIS container with Docker, then, in most cases,
you run the  initialization script  

iris session iris < iris.script 

This means you open a terminal session and feed your input line-by-line from the script.
And that's fine and easy if you call methods, or functions, or commands.

Hi,

I'm trying to run some scripting in Windows. I'm using an instance of the IRISHealth community. 

I'm just trying to run a simple sequence of commands so I can run irissession in a non-interactive mode, like:

irissession.exe IRISHEALTH -U "%SYS" < "myprogram.iris"

set $namespace="%SYS"
set cbk = "C:\Test1.cbk"
set log = "C:\Test1.

Starting out with ObjectScript, it is really exciting, but it can also feel a little unusual if you're used to other languages. Many beginners trip over the same hurdles, so here are a few "gotchas" you'll want to watch out for. (Also few friendly tips to avoid them)

NAMING THINGS RANDOMLY

We have all been guilty of naming something Test1 or MyClass just to move on quickly. But once your project grows, these names become a nightmare. 

➡ Pick clear, consistent names from the start. Think of it as leaving breadcrumbs for your future self and your teammates.

To better understand Streams in IRIS I'll start with a short

History

In the beginning (before IRIS), there was just basic access to external devices.
The 4 commands OPEN, CLOSE, READ, WRITE still work and are documented 
by  Introduction to I/O in detail.
Especially for files, this is a direct access to your actual file system.
You have to take care of any status or other signal in your code.  
Also, any code conversion or similar is up to you. 

Class %Library.File aka %File offers a large collection of methods and queries 
for standard operations on directories and files.

I have a custom defined priority field that is being stored as a number type

<record name="LocalClinicalMeSHTerms" type="serial">
<field name="LocalClinicalExpertiseCodedValue" type="{CODETYPE}" codeFamily="HSPD" codeTable="LocalClinicalExpertise" codeScheme="{MASTER}"/>
<field name="LocalCliniclDisplayOrder" type="number"/>
</record>

However, within the overviewIndividual.cls form

				{
					"type": "HSPD.collection",
					"key": "LocalClinicalMeSHTerms",
					"hideExpression": "formState.lib.hideField(formState) && model.

The ObjectScript language has incredible JSON support through classes like %DynamicObject and %JSON.Adaptor. This support is due to the JSON format's immense popularity over the previous dominance of XML. JSON brought less verbosity to data representation and increased readability for humans who needed to interpret JSON content. To further reduce verbosity and increase readability, the YAML format was created. The very easy-to-read YAML format quickly became the most popular format for representing configurations and parameterizations, due to its readability and minimal verbosity.

Hi Community,
I’m trying to execute a directory query in InterSystems IRIS using %SQL.Statement, but encountering an unexpected error.

Details:
The following command confirms that the directory exists:

Set dirPath="\\MYNETWORK_DRIVE\DFS-Shared_Product\GXM"
Write ##class(%File).DirectoryExists(dirPath)

It returns 1, meaning the path is valid and accessible.

However, when I try to execute this SQL query:

Set File=##Class(%SQL.Statement).%New()
Set Status=File.%PrepareClassQuery("%File","FileSet")
Set Result=File.%Execute(dirPath)
If Result.%SQLCODE {
    Write Result.

I was really surprised that such a flexible integration platform with a rich toolset specifically for app connections has no out-of-the-box Enterprise Service Bus solution. Like Apache ServiceMix, Mule ESB, SAP PI/PO, etc, what’s the reason? What do you think? Has this pattern lost its relevance completely nowadays? And everybody moved to message brokers, maybe?

Wiki time: An enterprise service bus (ESB) implements a communication system between mutually interacting software applications in a service-oriented architecture (SOA) .

Why This Matters

Managing IAM can be tedious when done manually — especially when your APIs are already well-documented using OpenAPI (Swagger) specs. Wouldn't it be great if you could automatically generate Kong services and routes directly from your OpenAPI spec?

That's exactly what this ObjectScript method does: it reads an OpenAPI 2.0 spec stored in the XData block of your spec class and generates a decK-compatible YAML file that can be used to sync your IAM configuration.

InterSystems FAQ rubric

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.

I’ve been exploring options for connecting Google Cloud Pub/Sub with InterSystems IRIS/HealthShare, but I noticed that IRIS doesn’t seem to ship with any native inbound/outbound adapters for Pub/Sub. Out of the box, IRIS offers adapters for technologies like Kafka, HTTP, FTP, and JDBC, which are great for many use cases, but Pub/Sub appears to be missing from the list.

Has anyone here implemented such an integration successfully?

For example:

• Would it make sense to leverage IRIS’s Business Service + REST API adapter to connect to Google’s Pub/Sub REST endpoints?

I joined InterSystems less than a year ago. Diving into ObjectScript and IRIS was exciting, but also full of small surprises that tripped me up at the beginning. In this article I collect the most common mistakes I, and many new colleagues, make, explain why they happen, and show concrete examples and practical fixes. My goal is to help other new developers save time and avoid the same bumps in the road.

1. Getting lost among system classes and where to start

The issue: ObjectScript/IRIS ships with many system classes and packages (%Library, %SYS, %Persistent, %SQL, etc.).

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.

Hello Community

The InitialExpression keyword values does not to set default values for properties in classes that extend %CSP.Page, unlike in other class types such as %Persistent or %RegisteredObject, where it works as expected during object instantiation (typically via %New()).

1. Is %CSP.Page instantiated using %New() under the hood, or does it use a different initialization mechanism?
2. Are there specific limitations or behaviors in CSP pages that prevent InitialExpression from working as expected?

Thank you!

Finishing my previous example for multiple IRIS instances, I tried
to compose a local single instance version.  The step from the external
Python app to a version using embedded Python seemed to be obvious.
This was a wrong assumption, as some Python libraries just refused installation
into my local Windows-based environment.
