What I find really useful about IRIS when teaching my subject of Postrelational databases is the fact that it is a multi model database. Which means that I can actually go into architecture and structure and all that only once but then show the usage of different models (like object, document, hierarchy) using the same language and approach. And it is not a huge leap to go from an object oriented programming language (like C#, Java etc) to an object oriented database.

However, along with advantages (which are many) come some drawbacks when we switch from object oriented model to relational. When I say that you can get access to the same data using different models I need to also explain how it is possible to work with lists and arrays from object model in relational table. With arrays it is very simple - by default they are represented as separate tables and that's the end of it. With lists - it's harder because by default it's a string. But one still wants to do something about it without damaging the structure and making this list unreadable in the object model.

So in this article I will showcase a couple of predicates and a function that are useful when working with lists, and not just as fields.

Reviewing a client console log, I am finding the message:

Terminal disconnect: The specified network name is no longer available.

This message is repeated in the log dozens of times per day over the last month. The client has not raised a concern and our monitoring has not detected any issues with client ops. The client is not aware of any recent changes with their apps. I am not familiar with this message and whether this message is benign or whether there is any action required,

This week I was able to demo a proof of concept for our FMS interface on traffic cop architecture to my team. We are working on modernizing an Interoperability production running on mirrored Health Connect instances. We deploy IRIS workloads on Red Hat OpenShift Container Platform using InterSystems Kubernetes Operator (IKO). We can define any number of replicas for the compute stateful set where each compute pod runs our Interoperability production. We introduced Horizontal Pod Autoscaler (HPA) to scale up the number of compute pods based on memory or CPU utilization.

Hi,guys

My client is using IRIS 2021.1 Interoperability and they want to highlight the sessions with unresolved(without resent and completed operations) errors so their maintenance team can have a list of unresolved sessions to check against.

When I'm working on it, it seems to be it is is difficult to decide whether a session have unresolved errors. For example,

Hi Team,
I have a requirement to disable the Production Start/Stop buttons for specific support users. But they should be able to stat/stop Ensemble Hosts.
For that new Role, As per documentation along with other Ens resources, I have added %Ens_ConfigItemRun with RWU access and didnt add %Ens_ProductionRun resource.

This makes the Start/Stop buttons disappear from Production Configuration page ( meeting my requirement). But those users are Unable Start/Stop/Restart Ensemble Business Hosts.

ZPMshow, a helper for tired fingers

The offer of ZPM is growing daily and the short names and
acronyms of the offer are sometimes hard to understand and
also hard to type with my lazy fingers.

So I decided to have

  • a listing with the descriptions from the repository,
  • split in short junks to avoid backscroll,
  • controlled forward / backward scrolling,
  • the option to select my packages by number,
  • to install or uninstall with limited typing.

It runs with do ^zpmshow

Hi Developers!

This post describes how you could publish your InterSystems application on Open Exchange.

What is the InterSystems application?

It could be anything, which is built with InterSystems data platforms or to help work with InterSystems data platforms: InterSystems IRIS, InterSystems IRIS for Health, InterSystems HealthShare, InterSystems Ensemble and InterSystems Caché. This could be tools, frameworks, adapters, examples and business solutions.

Why publish on Open Exchange?

InterSystems Open Exchange is an "App Central" for the solutions in InterSystems. It's the first place where the developer goes to look for tools, frameworks, and examples on InterSystems IRIS. And Open Exchange brings the added traffic to your solution which could be converted into leads.

We are having a set of business development tools for published Open Exchange applications. This definitely makes your InterSystems application more noticed.

Submitting an application

Suppose you have a library with open source published on Github which you want to publish on Open Exchange. For the purpose of a demo, I'll fork this remarkable project of @Peter Steiwer ObjectScript-Math which I forked and renamed to object script-super-math.

Hi Developers,

2019 was a really great year with almost 100 applications uploaded to the InterSystems Open Exchange!

To thank our Best Contributors we have special annual achievement badges in Global Masters Advocacy Hub. This year we introduced 2 new badges for contribution to the InterSystems Open Exchange:

✅ InterSystems Application of the Year 2019

✅ InterSystems Developer of the Year 2019

We're glad to present the most downloaded applications on InterSystems Data Platforms!

I looking to gain insight on if I can trigger a SMS text to a Clinician

New to HealthShare and trying to get the process for setting up a message.

Simple use case

Alert a Clinician if a patient meets specific requirements via an SMS text message.

I have set up a test physician in our dev environment, and enabled push notification on the Edges fro the MPI update manager.

Based off of the HEPUSH documentation.

Any direction to documentation or steps is greatly appreciated.

Thanks,

Hi,

I've built a custom HL7 searchtable, but wish to remove some of the items.

I've removed the items I no longer wish to index recompiled the custom searchtable, however the previous searchtable values are available when searching messages in the namespace.

Do I need to rebuild the index for this searchtable to purge searching the old values?

I have stop and started the production.

Regards

Stuart

Advisory for IRISSECURITY in InterSystems IRIS 2025.2

InterSystems IRIS 2025.2 introduces the IRISSECURITY database, the new home for security data. Unlike IRISSYS, the previous home for security data, IRISSECURITY can be encrypted, which secures your sensitive data at rest. In a future version, IRISSECURITY will be mirrorable.

This version also introduces the %SecurityAdministrator role for general security administration tasks.

M:N in Contest #1

M:N Relationship is a recurring object of my interest for a long time.
So the subject turns up with me repeatedly.
For this article, I found a nice example with TWO separate M:N relationships. Some M:N².

It is not pure fiction but taken from a closer view of OEX Contests that we run on a regular base.
