#InterSystems IRIS

Some time ago, I put together a small example to quickly deploy InterSystems IRIS instances connected via ECP using Docker.

Time passed and, like everything, it needed a bit of a refresh.

The InterSystems IRIS data platform underlies all InterSystems applications, as well as thousands of customer and partner applications across Healthcare, Financial Services, Supply Chain, and other ecosystems. It is a converged platform, providing transactional-analytical data management, integrated interoperability, and data integration, as well as integrated analytics and AI. It supports the InterSystems Smart Data Fabric approach to managing diverse and distributed data.

New Features and Enhancements

In the previous article, we talked about ODBC and connecting from C#. And now, let's look at JDBC and Java. The InterSystems JDBC driver is the recommended, high-performance way to integrate your Java applications.

Here is a step-by-step guide to getting your Java application connected to an IRIS instance using the JDBC driver.

Step 1: Obtain and Include the InterSystems IRIS JDBC Driver

Unlike ODBC drivers, which are often installed system-wide, JDBC drivers are typically distributed as JAR files that must be included in your Java project's classpath.

If InterSystems IRIS is installed on your local machine or another you have access to, you can find the file in install-dir/dev/java/lib/ or similar, where install-dir is the installation directory for the instance. Conversely, you can download the jar file from Driver packages page.

Or as suggested by @Dmitry Maslennikov in the comments, use the maven central repository for Maven:

<dependency><groupId>com.intersystems</groupId><artifactId>intersystems-jdbc</artifactId><version>3.10.5</version></dependency>

or for Gradle:

implementation("com.intersystems:intersystems-jdbc:3.10.5")

Include the jar file in Project:

• Maven/Gradle: If you use a build tool, the simplest method is to add the InterSystems JDBC driver as a dependency in your pom.xml or build.gradle file. This automatically downloads and manages the JAR.
• Manual: For simple projects, you must place the JAR file in a project directory (e.g., /lib) and explicitly add it to your classpath when compiling and running.

I am working on building out a Workflow task that captures errors in mapping to specific tables. Within the Workflow task, I would like to give the owner of the task the ability to resubmit message once the mapping has been corrected. Is there a way to do it in a similar fashion to pulling up the Trace ie...

EnsPortal.VisualTrace.zen?SESSIONID=#(%task.%FormValues.GetAt("MsgHdrID"))#" target="_blank">View Message Trace

Is there a one liner that could be called to resubmit the MsgHdrID (Session ID) from its source to post it again?

Introduction and Motivation

A unit of ObjectScript code (a ClassMethod, say) may produce a variety of unexpected side effects by interacting with parts of the system outside of its own scope and not properly cleaning up. As a non-exhaustive list, these include:

• Transactions
• Locks
• I/O devices
• SQL cursors
• System flags and settings
• $Namespace
• Temporary files

Use of these important language features without proper cleanup and defensive coding can lead to an application that normally works correctly, but that may fail in unexpected and difficult-to-debug ways.

Hey Community!

We're happy to share a new video from our InterSystems Developers YouTube:

⏯  Query Optimization in Hybrid Databases @ Ready 2025

When using standard SQL or the object layer in InterSystems IRIS, metadata consistency is usually maintained through built-in validation and type enforcement. However, legacy systems that bypass these layers—directly accessing globals—can introduce subtle and serious inconsistencies.

Understanding how drivers behave in these edge cases is crucial for diagnosing legacy data issues and ensuring application reliability.
The DATATYPE_SAMPLE database is designed to help analyze error scenarios where column values do not conform to the data types or constraints defined in the metadata.

Has anyone been able to successfully implement a business service to pull files from Azure Blob storage?

In Part 1, we explored how window functions operate. We learned the logic behind PARTITION BY, ORDER BY, and such functions as ROW_NUMBER() and RANK(). Now, in Part 2, let's delve into more window functions with practical examples.

1. Aggregate-over-Window Functions

Overview

These functions compute an aggregate (e.g., sum, average, min, max, count, etc.) over the defined window frame but don’t collapse rows.
Each row remains visible, augmented with aggregated values for its partition.

Supported functions include the following:

• AVG() — average of values in the window frame.
• SUM() — total of values

Parallel query hinting boosts certain query performances on multi-processor systems via parallel processing. The SQL optimizer determines when this is beneficial. On single-processor systems, this hint has no effect.

Parallel processing can be managed by:

1.  Setting the auto parallel option system-wide.
   

2. Using the %PARALLEL keyword in the FROM clause of specific queries.
   

%PARALLEL is ignored when it applied to:

1. INSERT, UPDATE, and DELETE queries (Only SELECT queries benefit from this feature)
2. The queries involving process-specific functions or variables
3. A subquery correlated with an

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.

Data for the test

How do I take SVG data to be an image in Logi Reports? Now I can take JPG data and render it in Logi Reports. And I can take the SVG data in ObjectScript, but when I view it in Logi Reports, it won't appear. How do I get the code in ObjectScript to appear and be read in Logi Reports?

Inevitably, you will eventually need to move your code up from one version of IRIS or Cache to a more recent version of IRIS. There are a few good steps you can take to set yourself up for success in that process.

Read Documentation Carefully

Before you move anything you should check out the IRIS documentation page for many useful resources on changes made to various versions of IRIS.If you are upgrading through multiple versions, you will want to check on the documentation for all of them, not just the version to which you will upgrade.

I am trying to add some validation to an existing Record Map, because recently we had some wrong data get consumed into the System and is causing all kinds of havoc.

Using the AI on the Developer community it suggested that I use PATTERN within the Datatype Parameters to force some validation on some fields. I have never used PATTERN before...

When I go to generate the updated Record Map, I am getting the following...

Hi community!

I am excited to say that since the beginning of this year we have published many of the client SDKs for InterSystems IRIS, InterSystems IRIS for Health and Health Connect to the corresponding external repositories (Maven, NuGet, npm and PyPI). This provides many benefits to you such as:

• You can access the latest releases for a client SDK as soon as they get published, independent of the InterSystems IRIS release cadence
• You can integrate the SDKs as a dependency with the native package manager tool within your ecosystem and manage dependencies in an industry-standard way
• End

gj :: configExplorer is a new VS Code extension integrating with Server Manager and leveraging Structurizr to produce configuration diagrams of your servers.

Here's a short introductory video.

By using the InterSystems IRIS Native API for Node.js it avoids the need for any support code to be installed on the servers. This technology choice also qualifies it for entry into the current Developer Community contest.

The initial release focuses on two aspects of server configuration:

• Namespaces and databases
• ECP connectivity

Suggestions for what to add next are welcome, as is general feedback.

Studio's Output window is interactive, and code can ask questions there if it is a Studio environment. How do I check for that?

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.
I think the system is does not understand that the test can find

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:

As part of improvements regarding CCR usage and usability, certain transitions are now blocked when a CCR Record has undeployed ItemSets for required Environments. 

To promote best practice, when a Tier 1 or Tier 2 CCR moves between Environments, it is important that ItemSets are deployed to required Environments before confirming that the CCR has successfully been implemented in the next Environment.Previously, when progressing a CCR from one Environment to the next, users were not required to deploy ItemSets before performing markMoveToXXXXComplete or markCANCELComplete transitions.
