Inside $LISTBUILD

Most IRIS developers use $LISTBUILD every day — often without even noticing it.

It is not just a convenient function for building lists. It is also the default internal format used to store row data, global values, and many intermediate structures inside the database engine.

Despite this, the actual binary representation of $LISTBUILD values is rarely discussed. Most developers rely on its behavior, but never look at how the data is really stored.

This article focuses strictly on the binary layout of $LISTBUILD values, based on direct inspection via zzdump.

How to create a processes-shared singleton in IRIS?

I need a %SYS.Python object that will be accessible from different processes. The goal is to avoid reinitializing the Python object whenever it is called. Ways that I checked and decided that it is NOT what I want:

  • %-variables (process variables). Reusing only in the same process
  • Save-and-restore via globals. Restoring means heavy initialization, which I want to avoid

Next, my ideas (none of them look like a silver bullet):

  • Using Interoperability Production.

Improving legacy asynchronicity in hyperevent(#call)

Hello, community.

I've been working with Intersystem Caché for two years, and right away I was excited about the rich ecosystem that Caché provides. However, I was disappointed with calls using #call, and I understand that it was a limitation of the time. Well, the frustration is that #call returns null by default, meaning an AJAX request is executed, but there's no hook to retrieve the return from that request. The only way to retrieve the data from that request is by building a callback on the server side using &js<>.

Developing a Microservice Application using IRIS, Kafka, and REST API

What is a Microservice?

A microservice is an architectural style that structures an application as a collection of small, autonomous services. Each component is developed around a specific business capability, can be deployed independently, and is typically managed by a miniature, specialized, self-governing team. (Source: https://microservices.io/)

Request for Auto-Start Configuration Steps for Cache 2018 on AIX

Hi Team,

We are currently running InterSystems Caché 2018 on an IBM AIX server and would like to configure the Cache instance to start automatically when the server boots or is rebooted.

Could you please provide the recommended steps or any official scripts/guidelines to enable auto-start for the Cache instance (QA2018) on AIX?

Additionally, if there are any best practices or prerequisites (such as filesystem mount options, service dependencies, or startup order) that we should consider, please share those as well.

Thanks,
Ganesh

Prevent specific table data from being rolled back

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.

Scripting with .Net core 10 and Iris SDK

One of the newest features of .Net core 10 with C# 14 is the file-based apps. This feature allows you to execute C# code in a simple .cs file without the need to create a solution, a project, or any of the related structure.

For example you can create a script.cs file using the notepad with the content: 

Console.WriteLine(“This is a script in c#.”);

Then in the command line or the terminal you execute the command:

dotnet run script.cs

There is plenty of information about this new feature of .net 10.

Teaching an AI Coding Agent to Work Safely with a Legacy InterSystems Caché Application

We didn't start with a big AI strategy.

We had a legacy InterSystems Caché 2018 application, a lot of old business logic, and a practical need: build a new UI and improve code that had been running for years. At first, I thought an AI coding agent would help only with a small part of the work. Maybe some boilerplate, some REST work around the system, and a bit of help reading old ObjectScript.

In practice, it became much more than that.

Supply Chain - Supply Chain Orchestrator (SCO)

Before finding the best solution for Supply Chain, we need to understand what Supply Chain is. Well, regardless of the language used, the term is known by the name already mentioned. For your information, the translation in Brazilian Portuguese is "Cadeia de Suprimentos" (Supply Chain), sometimes also called "Cadeia Logística" (Logistics Chain), but we will not dwell on the nomenclature, but rather on the meaning.

How I usually learn InterSystems IRIS (resources + notes)

Hi, every one. Again, it's me!!😀😀

Recently I was trying to organize some learning materials for InterSystems IRIS😆, and realized that the resources are actually quite scattered.🤐

So I put together a list here—grouped by categories—for anyone who:

  • is new to InterSystems
  • or wants to go deeper into specific areas

Also adding some of my own experience on what worked (and what didn’t, may be only not work for me🤫🤐).

Practical ObjectScript Coding: From JSON to Globals to SQL

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.

How to use JobServer properly to have a certains amount of IRIS processes available amongs multiple Apache nodes ?

I use cspa24.so Apache module to connect to IRIS. I have notified that idle Apache processes will always result in connections being kept open to the IRIS server, and thus some amount of IRIS processes being kept alive (and dedicated to those apache processes) because of those connections.

Eg: if I have 50 idle Apache processes, I will have 50 IRIS processes being kept alive in IRIS even if there is no client connection being made at that time. 

It's even worse with multiple Apache nodes and a load balancer.

Convert Python %SYS.Python List to %Library.DynamicArray in Objectscript

As part of a recent documentation technical project to optimize the search, I needed to use Embedded Python in my ObjectScript code. The main blocker was passing a Python list from a Python class method to a ObjectScript method. Sending the list by reference to the python method, populating it with the Insert() method, and returning the reference to the ObjectScript method resulted in an list with type %SYS.Python, a process that was straightforward but not efficient.
I explored an alternative method: converting a Python list to an ObjectScript list using JSON as the intermediary format.

Code not always updated in Mirror?

This past weekend we ran into something odd. When we failed over our mirror from 2022.1.3 to 2025.1.3 the one of the Business Rules that was on what became the Primary (2025.1.3), had a rule within it that was removed back in January. When the Failover occurred, we had to scramble to backup, disable, and remove the Rule that shouldn't have been there. 

Both the Data and Code live within the same IRIS.dat that is the main MIRROR database for that Namespace. 

If this happened to one Class file, could it happen to others we do not know about?
