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). Messages flowing through those components constantly require being adapted to consuming applications. Therefore,Data transformations are by far the most common component in interoperability productions.

In the early stages of data transformation development, the test tool from the Management Portal becomes quite handy.

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.

ClassMethod CheckPDMProviderType(pInput As %String) As %Boolean
{
    set ExtDisplay = ""
 		&sql(SELECT SecurityGroup_k INTO :ExtDisplay
        FROM osuwmc_CPD_SQL.

InterSystems FAQ rubric

There is data, such as execution log data, that you do not want to return to its previous state even if a rollback occurs during a transaction. The above requirement can be met by placing that data in the IRISTEMP database, which will not be rolled back.

Temporary Globals and the IRISTEMP Database

By mapping the table entities you do not want to roll back to this database, you can retain the information after the rollback.

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,

I need a custom operation on patient type that will receive a business identifier and will search them and for each paient it will return a $everything for all the found patients written with object script

I have a need to create a specific Search Table outside of the EnsLib.HL7.SearchTable specifically for HL7 MFN messages in HealthShare Provider Directory.

Our Code is created in a different namespace then the main HSPD namespace and is mapped within the HSPD namespace mapping. 

I created a copy of EnsLib.HL7.SearchTable, named OSU.HL7.SearchTable what all needs mapped to make this new search table available in HSPD namespace?

If I go to Global within the Custom Code Namespace, I cannot see my new Search Table being created.

What am I missing to make sure that the OSU.HL7.

Developing with InterSystems Objects and SQL – In Person September 15-19, 2025

• This 5-day course teaches programmers how to use the tools and techniques within the InterSystems® development environment.
• Students develop a database application using object-oriented design, building different types of IRIS classes.
  
  • They learn how to store and retrieve data using Objects or SQL, and decide which approach is best for different use cases.

Interoperability on Python (IoP) is a proof-of-concept project designed to showcase the power of the InterSystems IRIS Interoperability Framework when combined with a Python-first approach.IoP leverages Embedded Python (a feature of InterSystems IRIS) to enable developers to write interoperability components in Python, which can seamlessly integrate with the robust IRIS platform. This guide has been crafted for beginners and provides a comprehensive introduction to IoP, its setup, and practical steps to create your first interoperability component. By the end of this article, you will get a clear understanding of how to use IoP to build scalable, Python-based interoperability solutions.

InterSystems OMOP, The Cloud Service (Troy)

While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together. 

1. Working with Dynamic Objects:

Dynamic objects (%DynamicObject and %DynamicArray) allow developers to manipulate JSON-like structures directly in Objectscript. They are especially useful for modern applications that need to parse, transform or generate JSON.

This article outlines the process of utilizing the renowned Jaeger solution for tracing InterSystems IRIS applications. Jaeger is an open-source product for tracking and identifying issues, especially in distributed and microservices environments. This tracing backend that emerged at Uber in 2015 was inspired by Google's Dapper and Twitter's OpenZipkin. It later joined the Cloud Native Computing Foundation (CNCF) as an incubating project in 2017, achieving graduated status in 2019. This guide will demonstrate how to operate the containerized Jaeger solution integrated with IRIS.

Introduction

What's in a name? That which we call a rose
By any other name would smell as sweet

William Shakespeare, "Romeo & Juliet"

In this article, we will describe a set of naming conventions for ObjectScript code.

The operations manager in our company was using structured logging in IRIS to tail information to an on-prem monitoring tool and started to get concerned with the ever-growing size of the output file. He just leaned across the aisle here and informed me that the output file has no mechanism for rolling this file over at a certain point for archival or disposal. Sure enough, I can't find any documentation to refute this.

Hello Community,

I’m working on an InterSystems IRIS production that needs to call an external API using OAuth client credentials (client_id and client_secret). For security reasons, I must pass these credentials via environment variables in my Docker container.

In the IRIS terminal, I can successfully retrieve these environment variables using $System.Util.GetEnviron("api-clientid") and $System.Util.GetEnviron("api-clientsecret"). However, inside my Business Operation class (OnMessage method), these environment variables return empty strings.

This article is a continuation of the IRIS JSON project and features additional methods and insights.

Let's continue with the instance methods

%GetTypeOf(Key)

This instance method is used to determine the JSON data type of the %DynamicObject or %DynamicArray.

It returns one of the following strings:

USER>Set array = [1,"test",true,12.

Been testing out the Production Validator toolkit, just to see what we can/not do with it. Seems really interesting and there seem to be some use cases for it that can really streamline some upgrades (or at least parts of upgrades) but I was running into so many hurdles with the documentation. I am curious if anyone else has used it.
Did you experience any issues getting it working? Any clarification that you would have liked in the documentation? any use cases that you worked through that made it particularly valuable? etc?

Hello Community,

I'm currently planning a system upgrade from Caché (2018.1.8.766) to InterSystems IRIS (2024.1). The environment consists of one database server and three application servers connected via ECP.

I’m considering two possible upgrade approaches:

1. Upgrade the application servers to IRIS first.
   Since IRIS is expected to be backward-compatible with Caché over ECP, the database server would remain on Caché temporarily.
2. Upgrade the database server first,
   followed by upgrading the application servers, as they don’t store data.

Hi everyone,

I'm developing an Ensemble process that sends user data from a Business Process to a Business Operation using EnsLib.SQL.OutboundAdapter. The operation is supposed to call a stored procedure on a SQL Server.

The stored procedure expects 3 parameters:
@FirstName, @LastName, and @Email.

The procedure works fine when executed directly from SQL Server Management Studio.

However, when I trigger it via Ensemble, I get the following error:

[SQL Server] Incorrect syntax near 'email@domain.

Data is at the heart of the digital transformation sweeping healthcare. Radical change requires a new foundation to handle the massive data demands of modern healthcare.

Time to market is crucial as you develop the next therapeutic breakthroughs, genomic insights, and intelligent clinical workflows. You need to deliver them now.

That’s why we’ve extended the power of our InterSystems IRIS Data Platform to address the unique characteristics of healthcare information. InterSystems IRIS for Health is the world’s first and only data platform engineered specifically for the rapid development of healthcare applications to manage the world’s most critical data.

I installed and configure CodeTidy in my local development environment, without InterSystems source-control (git-source-control) and only git for source control.

I would like to use only CodeTidy to stablish an automated  Linting and Code Style Validation for InterSystems ObjectScript code triggered by GitHub Actions.

Could you shed some light on how to accomplish that?

I have a table with 5M rows, the table contains lab observation codes and display names, both columns have type varchar(2000) and both are indexed.

The query looks like:

select code_1_text, count(code_1_text)
  from demo.observation_lab
  group by code_1_text
  order by 2 desc

The table contains ~1000 distinct display names.

It takes 4 minutes for the query to complete on a VM with some pretty old Xeon, 4 cores, 32G RAM, NVME SSD and Linux on board.

Isn't it too slow?

If you want to find out what exact version your Docker image is (and since the latest image tagging scheme you cannot just rely on the image tag; and assuming you don't want to actually run it just in order to find out) you can run this docker command:

Hi I have a SDA3 created from large CCDA file, i am trying to map the SDA object to Stream using tSDA.ToQuickXMLStream(.tSDAOut).. i am getting xml parse error.. it works when the files are smaller.. Is there a workaround to get SDA to a stream

Greetings dear community members!

Many of you will remember the NLP capabilities available in IRIS under the name iKnow, which were deprecated not long ago. But...is everything deprecated? NO! A small village resists deprecation: iFind indexes!

Trying to extract the narrative text from large CCDA files using EnsLib.EDI.XML.Document:GetValueAt method

Getting a MAXSTRING error from the GetValueAt method.. Tried alternate by using GetSubDocumentAt and put it to string. Still it is giving a Invalid OREF method. Is there any limitation on these OOB methods. Also looking for ideas to extract it
