Running the InterSystems IRIS image 5.1 Starting an IRIS container 5.2 Checking container status 5.3 Executing code in the container terminal 5.4 Accessing the IRIS Management Portal 5.5 Connecting the container to VS Code 5.6 Stopping or removing the container 5.7 Setting a specific password with a bind mount 5.8 Using durable %SYS volumes 5.8.1 What gets stored with durable %SYS 5.8.2 How to enable durable %SYS
Using Docker Compose 6.1 Docker Compose example 6.2 Running Docker Compose
Using a Dockerfile to run custom source code 7.1 Dockerfile example 7.2 Docker Compose example 7.3 Understanding layers, image tagging and build vs. run time 7.4 Source code and init script 7.5 Building the image with Dockerfile 7.6 Running instructions in the containerized IRIS terminal
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.
With InterSystems industry-standard certification exams, you and your team can get certified to validate your skills and demonstrate your expertise in InterSystems technology. Find the right exam for your role!
I needed to pick up the username from a set of credentials configured for a business operation in an interop production, and it turned out to take a few steps, so I'm sharing my method here, in the dual hope that someone has an easier way to do it, or failing that, that it is useful to someone.
One way to optimize query performance is to use query parallelism on a per-query or system-wide basis (a standard feature).
This is a technique for dividing the execution of a particular query among processors on a multi-processor system. The query optimizer will execute parallel processing only if there is a possibility of benefiting from parallel processing. Parallel processing is only applicable to SELECT statements.
When we need to integrate Caché/IRIS with other relational databases, one common question arises: “How do I set up the JDBC connection?”. The official documentation doesn’t always provide a straightforward step-by-step guide, which can be frustrating, especially for beginners.
Our vendor is developing an interface API on their end to capture HL7 data on a Server Port, and they require us to send a pre-defined HL7 Order message for testing every hour until the API is completely operational.
Is it possible to accomplish that in a Business Operation automatically without utilizing a service or process? The BO is a standard TCP/IP connection.
I'm manually sending the message again from the Operations right now. I do not have access to the System Operation to use the Task Manager feature.
For a variety of reasons, users may wish to mount a persistent volume on two or more pods spanning multiple availability zones. One such use case is to make data stored outside of IRIS available to both mirror members in case of failover.
Unfortunately the built-in storage classes in most Kubernetes implementations (whether cloud or on-prem) do not provide this capability:
My understanding that in IRIS we create an Inbound Adapter that would act like a Broker (connecting to server X) then have an MQTT outbound adapter to receive those messages?
Is there a quick sample that we could user to show how to setup these two Adapters, I started with this but I couldn’t for example find EnsLib.MQTT.Adapter.Inbound
I am working on a tool that configures an instance to use a common default routine database across all custom Namespaces. For instances that already have distinct default routine databases for their Namespaces, this would involve a step of merging over all code from the current default routine databases to the new "super" routine database. This should be done in such a way that only merges contents in the default routine database (not mapped databases) and is able to detect/exclude contents that already exist in the target database.
For historic reasons we've got a mix of ADT feeds coming out of our PAS (TrakCare) to a wide range of downstream systems. In particular, there are some that are direct from TrakCare to the downstream systems, and many more that pass through Ensemble as our integration engine.
This is complicating management of the integrations, and so we'd like everything to go through the integration engine. In other words move from the flow in the top of the diagram to the flow in the bottom of the diagram:
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.
Following on from JediSoft’s announcement of the general availability of JediSoft IRISsync®, I wanted to show how it can help prevent configuration drift and ensure your failover is always ready.
Hello to all my fellow Cache Developers/Experts out there :)
The purpose of this post is to get input/feedback regarding an issue we are having with our Cache LIS web-based application not being able to remove locks that were taken under a separate process.
Here is the background of how the LIS does the locking and details about the issue:

Good day, Agent IRIS,
We're sorry for interrupting your vacation in the Bahamas, but we just received word from our London agent that a "time bomb" is set to detonate in a highly populated area in Los Angeles. Our sources say that the "time bomb" is set to trigger at 3:14 PM this afternoon.
I've noticed that some of my friends and colleagues are using the Developer Community app on their Android devices. Could someone please help me with the exe file or guide me on how to get it?
We've got an engaging video, perfect for all skill levels.
