I was recently troubleshooting a problem on a Linux (RHEL) instance of 2016.1 at a site. For policy reasons their sysadmins wanted to update the Caché installation so it used network accounts for its cacheusr and iscagent users and groups instead of the locally-created ones that had been set up during original install of Caché.

To do this they ran various commands including chown

Afterwards non-root users couldn't obtain a terminal session using the csession command. Instead they receive this message:

cache: Permission denied

Cross-origin Resource Sharing (CORS) is one of the basic security features built into browsers. CORS controls accessing resources from a HTML page in domains other than the original domain. It is particularly important for AJAX calls. Since RESTful services can be used as data provider to any AJAX call, you have to be able to control cross-origin access. By default services are not allowed to do CORS. You are going to learn how to enable it for Ensemble RESTful services.

At the end of our last lesson, we ended with our page displaying a nice (but garish) Angular Material Toolbar, and our Widget data displaying in a list of Material cards. Our page feels a bit static, and we already know that the large number of Widgets that we will be dealing with will not be especially usable on a static list. What can we do to help?

Hello developers!
I present to you the project of editors in terminal mode. The full-screen editor of routines, arrays and text files in terminal mode can be useful to you when debugging your project in docker or when your web interface is unavailable or limited for some reason.
Although this project is self-sufficient, I decided to make it as an addition to the ‘zapm’ module for the convenience of calling editor commands.

If your instance does not have a ZPM, then you can install the zapm-editor module in one line:

Hi Developers!

Those who use Dockerfile to work with InterSystems IRIS often need to execute several lines of ObjectScript. For me, this was a game of "escaping this and that" every time just to shoot a few commands on ObjectScript to IRIS. Ideally, I'd prefer to code ObjectScript without any quotes and escaping.

Recently I found a nice "hack" on how this could be improved to exactly this state. I got this from @Dmitry Maslennikov's repo and this lets you use Objectscript in a way as you would type it in IRIS terminal.

Here is what you have in dockerfile:

///
COPY irissession.sh /
SHELL ["/irissession.sh"]
RUN \
  do $SYSTEM.OBJ.Load("Installer.cls", "ck") \
  set sc = ##class(App.Installer).setup()
# bringing the standard shell back
SHELL ["/bin/bash", "-c"]
CMD [ "-l", "/usr/irissys/mgr/messages.log" ]
///

Last time we deployed a simple IRIS application to the Google Cloud. Now we’re going to deploy the same project to Amazon Web Services using its Elastic Kubernetes Service (EKS).

We assume you’ve already forked the IRIS project to your own private repository. It’s called <username>/my-objectscript-rest-docker-template in this article. <root_repo_dir> is its root directory.

Before getting started, install the AWS command-line interface and, for Kubernetes cluster creation, eksctl, a simple CLI utility. For AWS you can try to use aws2, but you’ll need to set aws2 usage in kube config file as described here.

In this article I'd like to share with you a phenomena that is best you avoid - something you should be aware of when designing your data model (or building your Business Processes) in Caché or in Ensemble (or older HealthShare Health Connect Ensemble-based versions).

Some Usage cases

1. A deployment may consist of two high availability instances and two disaster recovery instances in a different data center.

The corresponding UAT environment could replicate this giving a total of 8 instances. How do you confirm CPF and Scheduled task alignment across ALL instances.

Welcome community members to a new article! this time we are going to test the interoperability capabilities of IRIS for Health to work with DICOM files.

Let's go to configure a short workshop using Docker. You'll find at the end of the article the URL to access to GitHub if you want to make it run in your own computer.

Previously to any configuration we are going to explain what is DICOM:

We return to the attack with our EMPI!

In previous articles we have seen how to configure and customize our EMPI, we have seen how we can include new patients in our system through HL7 messaging, but of course, not everything is HL7 v.2 in this life! How could we configure our EMPI instance to work with FHIR messaging?

Introduction

InterSystems would like to optimize IRIS to take advantage of modern CPU instruction set extensions. That’s great for product performance, but how do you know if your CPU will still be supported for new IRIS builds? Here’s how to know your CPU’s microarchitecture family as well as how to find out your CPU’s specific instruction set extensions.

What about DMN?

A few months ago, I faced a significant challenge: streamlining the handling of business logic in our application. My goal was to extract the business logic from the code and hand it over to analysts. Dealing with a multitude of rules could easily result in a code littered with countless "if" statements, especially if the coder lacked an understanding of cyclomatic complexity. Such code becomes a source of pain for those working with it—difficult to write, test, and develop.

Background

In 2021, I participated as an InterSystems mentor in a hackathon, where a newcomer to FHIR asked me if there was a tool to transform generic JSON data containing basic patient information into FHIR format. I informed her that I didn't know anything like that, unfortunately.

But that idea stays in my mind...

Several months later, in 2022, I came up with an idea to experiment: to train a named entity recognition (NER) to identify FHIR elements into generic texts. The training involved synthetic FHIR data generated by Synthea and the spaCy Python library.

2016.2 Field Test Kit 2016.2.0.585.0

I am pleased to announce the next in the series of 2016.2 field test kits, 2016.2.0.585.0.

In the two weeks since the last field test posting Development has made over a hundred fixes and improvements in Atelier, Enterprise Manager, Ensemble and Caché.

In Atelier alone there were over a dozen changes including a fix for the incompatibility issue that Jamie Newton described in his posting of February 1.

In Caché major areas of focus include:

Introduction

Any election is a highly mysterious process, and when you look at its results, the overall picture is not quite clear. I decided to put them, region by region, on the map of Moscow using InterSystems technologies that offer both storage and data analysis functionality. In this particular case, I used InterSystems Ensemble, a platform for application development and integration, but you can also build this solution using the multi-model InterSystems Caché DBMS, as well as InterSystems’ new product called IRIS Data Platform.

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

  • Git 101
  • Git flow (development process)
  • GitLab installation
  • GitLab Workflow
  • Continuous Delivery
  • GitLab installation and configuration
  • GitLab CI/CD
  • Why containers?
  • Containers infrastructure
  • CD using containers
  • CD using ICM

In this article, we'll build Continuous Delivery with InterSystems Cloud Manager. ICM is a cloud provisioning and deployment solution for applications based on InterSystems IRIS. It allows you to define the desired deployment configuration and ICM would provision it automatically. For more information take a look at First Look: ICM.

Introduction

In the first article in this series, we’ll take a look at the entity–attribute–value (EAV) model in relational databases to see how it’s used and what it’s good for. Then we'll compare the EAV model concepts to globals.
