Sub-Table Security

InterSystems IRIS provides extensive configurable security options, yet many developers primarily use roles and resources to secure entire tables or routines. Today, we will delve deeper. We can also secure individual columns and rows separately, but these two mechanisms operate very differently. Let's begin with the columns.

Column Security

For testing and demonstration, we will keep our table structure concise and straightforward. We have a table called "Person" in the USER namespace that contains an ID column, a date of birth column (DOB), first name, and last name.

Security in IRIS

Security is fundamental to enterprise application development. InterSystems IRIS provides a comprehensive security framework that protects data, controls access, and ensures compliance. This guide introduces essential security features for developers new to IRIS, covering authentication, authorization, encryption, and practical implementation strategies.

Can someone give me an explanation of how Local.PD.Linkage.Definition.Individual works? This was setup by another company as part of our implementation.

Below is my configuration..

We are getting a lot of matches on Given Name, but then the Family Name does not match at all, so I am wondering if these need to be adjusted. I just don't understand if they need to be positive or negative.

So, you checked your server and saw that IRISTEMP is growing too much. There's no need to panic. Let’s investigate the issue before your storage runs out.

Step 1: Confirm the IRISTEMP Growth Issue

Before assuming IRISTEMP is the problem, let’s check its actual size.

Check the Free Space

Run the following command in the IRIS terminal:

%SYS>do ^%FREECNT

When prompted, enter:

Deploying new IRIS instances can be a time-consuming task, especially when setting up multiple environments with mirrored configurations.

I’ve encountered this issue many times and want to share my experience and recommendations for using Ansible to streamline the IRIS installation process. My approach also includes handling additional tasks typically performed before and after installing IRIS.

At the moment, we have 10 HealthShare instance servers (5 x mirrored pairs), where we implement an External Backup approach, using the freeze/thaw commands against whichever server of the pair is the backup mirror member, to complete a VM level backup. These backups are stored to a disk within our control, to purge as required. This approach allows us to deliver a zero downtime backup approach.

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.

Securing IRIS Integrations with Mutual TLS (mTLS): A Practical Guide

In today’s enterprise environments, secure communication between systems is not optional—it’s essential. Whether you're integrating InterSystems IRIS with cloud APIs, internal microservices, or third-party platforms, Mutual TLS (mTLS) offers a powerful way to ensure both ends of the connection are authenticated and encrypted.

This post walks through how to configure IRIS for mTLS and how to validate your certificates to avoid common pitfalls.

Hi everyone,

I’m working with an existing InterSystems IRIS server that hosts several web applications and namespace-specific code and data. I’d like to reverse-engineer the current environment into a %Installer.Manifest file so I can store it in Git and manage its changes.

My goal is to:

We have messages that are in a queued state for various reasons and when we do a manual shutdown of the instance, they are moved to a Suspended state. I thought I saw in the documentation somewhere a setting to make sure these messages stay in a queued state and not suspend them. Can someone confirm and point me in the correct location for that documentation, as I am trying to ensure that if we do have to manually shutdown a instance, someone doesn't have to remember to go back in and check for suspended messages and resubmit them?

Thanks

Is it possible to audit code changes in a namespace?

Ideally what we'd like to be able to do is check which classes were compiled (or deleted) in a time period, eg in last 3 months, and which user made those changes. Even better would be an audit of what those changes were, but that's less important (for us, as we can probably find that information in other ways).

I have created a New Database/Namespace within our TEST environment on both the Primary and Backup of the mirror. When I go to create the database/namespace on the DR node I am getting "Cannot open file '/ensemble/TEST/iris.cpf_...." while the cpf file that it references does not exist. Anyone have any clue to why this might be happening?
