Hi all,
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.
Best,
Otto

InterSystems FAQ rubric

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.

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.

Background

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:

• Does not support access mode "ReadWriteMany"
• Does not support being mounted on more than one pod at a time
• Does not support access across availability zones

Hi,

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

and I guess here where I can set Server X IP & port

Not familiar with MQTT, I appreciate if you could take through how to setup a MQTT inbound & outbound adaptes ?

Thanks

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.

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.

🔐 What is Mutual TLS (mTLS)?

Building and Managing HL7 Integrations – In Person October 20-24, 2025 9:00am-5:00pm EDT

Build, configure, and manage HL7® V2 interfaces using InterSystems integration technologies.
This healthcare-focused 5-day course teaches implementation partners, integrators and analysts how to rapidly build HL7 integration solutions.
Students build a production that processes and routes HL7 messages.
Students learn how to work with the pre-built HL7 business services, business processes and business operations to receive and send HL7 messages.
Students also learn how to transform HL7 messages

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. 

When managing InterSystems IRIS production servers, even a minor configuration change can cause significant issues if it’s not replicated in your mirror environments. Often, these differences go unnoticed until your failover environment breaks.

This common, but critical, problem can lead to unexpected downtime at a vital moment and impact your business continuity.

⏯  Explaining Agentic AI Through Automated Bug Fixing

We are trying to make an ODBC connection via our intersystems ensemble (2016.2 running on ubuntu). However, when I am testing the connection I receive a pop-up that: "Http object response incomplete or invalid.0,#R". Note that the iodbctrace.log remains empty (and it is working because on the first try it registered a 459 error that I should activate kerberos, which I did). Any advise where I should look?
I have taken the following actions:

1. Expand the cacheodbc.ini in the mgr directory as follows:

As the title says, I've noticed that files that gets saved to the disk where the database lies (.DAT file) in the stream directory, does not get purged. Is this expected and do we need to create our own schedule task to clean this folder up?

I could only find old answers that say this, however I find it a bit odd if that is the case because they are considered temporary files. Perhaps I do not handle the streams correctly in the code?

set fileToDisk = ##class(%Stream.FileBinary).%New()
set fileToDisk.Filename = fileDestinationPath
set copyStatus = fileToDisk.CopyFromAndSave(response.Data)

Hi everyone,

I'm currently seeking a new position related to InterSystems technologies. My major skill is app integration and data flow development on the InterSystems IRIS platform (Interoperability). I develop high-load, mission-critical software. My coding background on Cache ObjectScript includes hundreds of data flows, thousands of Production business hosts, dozens of APIs, and other solutions on InterSystems IRIS. I worked to integrate such applications as SAP S/4HANA, Oracle Siebel, SAP Commerce Cloud, many custom apps, and all that can be integrated. I have also gained experience in various areas, including SQL, Java, Docker, IRIS administration, Apache Kafka, and Flutter (Dart).
