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.

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🤫🤐).

1. For starters

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.

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?

Introduction to Interoperability on Python (IoP) - Part3

Hi Community,

In our two preceding articles, we explored the fundamentals of the Interoperability Embedded Python (IoP) framework, including message handling, production setup, and Python-based business components.

In this third piece, we will examine advanced methodologies and practical patterns within the IoP framework that are pivotal for real-world interoperability implementations.
We will explore the following topics: 

✅ DTL (Data Transformation Language) in IoP
✅ JSON Schema Support
✅ Effective Debugging Techniques

Collectively, these features help us create maintainable, validated, and easily troubleshootable production-grade interoperability solutions.

Embedded Python programming with Claude Code: A bit of a trap

Claude Code has a strong understanding of IRIS, but unexpected issues still occur.

The first issue is one that has already happened several times and is likely to continue occurring if not properly addressed.

In IRIS, the collation for string data (%String) is set to SQLUPPER by default. As a result, when data is retrieved via SQL, it may be returned in uppercase (for example, when sorting and aggregating with GROUP BY).

Building a dynamic Object: how can I use variables?

Hi developers!

In a method I need to return a result as a dynamic object aka JSON Object. And here is my logic:

Classmethod Planets() as %DynamicObject {

 set val1="Jupiter"
 set val2="Mars"
// this doesn't work! cannot compile
 return {"value1":val1, "value2":val2}

}

So I need to do the following:

Embedded Python Programming with Claude Code

Since I started using Claude Code, my motivation to create things has skyrocketed.

Previously, even if I wanted to build something, actually doing the coding felt like a hassle, so unless there was a very strong need, I rarely went as far as programming. But now, if I just jot down the specifications, Claude Code handles the rest automatically, resulting in a dramatic improvement in productivity.

I come from a generation native to ObjectScript, so I used to feel some hesitation when it came to switching to Python.

Configuration item disabled, but shows enabled on Namespace

I am trying to built a Task that kicks off a Workflow to pull data into HSPD, and when I try to test the Task

ClassMethod TestTask()
{set tTask = ##class(OSU.Workday.TerminationsTask).%New()set tTask.DaysBack = 1 $$$ThrowOnError(tTask.OnTask())}

I keep getting TestTask+3^OSU.Workday.TerminationsTask.1 *%Exception.StatusException ERROR <Ens>ErrConfigDisabled: Configuration item 'OSU.DataSource.Workday.TermService' is disabled

But within the Namespace the OSU.DataSource.Workday.TermService shows enabled.

Here is my Task that I am using...

Class OSU.Workday.TerminationsTask Extends %SYS.

TypeScript (React) programming with Claude Code

This time, it’s not really programming per se, but we are using React as a front-end development tool for IRIS. When using a web development framework—not limited to React—one key consideration is which CSS framework to use. Up until now, we’ve been using Bootstrap, which is the standard and the easiest to get started with.

However, while it’s easy to use, I felt that it offers limited flexibility for customization. That said, even if we were to switch to another CSS framework, learning it and rewriting everything from scratch would be a significant effort, so we left things as they were.

Deltanji webinar: source control designed for change, built for you.

Is your source control treating your InterSystems IRIS environment like a simple collection of files? Most source control tools lack the native intelligence to handle InterSystems IRIS, which is why your code is treated as such. 

Deltanji is different. It understands how code and other artifacts are stored within IRIS and can manage them directly. This eliminates the friction that other tools introduce to the process. 

Join us for an InterSystems-hosted webinar to see how Deltanji provides an enterprise-grade source control solution that is tightly integrated with your IRIS environment.

Difference between Extending EnsLib.SQL.Snapshot vs creating a Property for EnsLib.SQL.Snapshot

We are working on Disk Consolidation and looking at Class/Globals that are rather large and not being cleaned up by the nightly Purge process. We have implemented DeleteHelper - A Class to Help with Deleting Referenced Persistent Classes | IDC on any Custom Data Classes, and Business Processes (BPL).

We have a bunch of Data Classes, BPL's, and Operations that connect to external MS SQL Server using JDBC to query or write data to using Stored Procedures and Queries. All that Query external tables are using EnsLib.SQL.Snapshot, and this is being written to ^Ens.AppData which is not cleaned up.

Complementing IRIS with MLflow for a Continuous Training (CT) pipeline

A Continuous Training (CT) pipeline formalises a Machine Learning (ML) model developed through data science experimentation, using the data available at a given point in time. It prepares the model for deployment while enabling autonomous updates as new data becomes available, along with robust performance monitoring, logging, and model registry capabilities for auditing purposes.

InterSystems IRIS already provides nearly all the components required to support such a pipeline. However, one key element is missing: a standardised tool for model registry.
