Previously I showed you how to run pButtons to start collecting performance metrics that we are looking at in this series of posts.
##Update: May 2020.
Since this post was written several years ago, we have moved from Caché to IRIS. See the comments for an updated link to the documentation for pButtons (Caché) and SystemPerformance (IRIS). Also, a note on how to update your systems to the latest versions of the performance tools.
pButtons is compatible with Caché version 5 and later and
Hi folks!
When I start IRIS in docker every time I do the following:
$ docker-compose up -d --build $ docker-compose exec iris iris session iris USER>zn "NAMESPACEINEED"
Is it possible to have an open terminal command connect to a particular namespace?
Hi Developers!
As discussed in previous parts of Package Manager stories to turn your IRIS application into a deployable package you just need to introduce the module.xml file into the root folder of the repository and describe all the resources.
I’m pleased to introduce you to a new project template on Open Exchange which contains examples of how to make different types of resources of your InterSystems IRIS application a part of the ObjectScript package and so make the deployable ObjectSctipt package.
Let's see how you can describe your application resources using this template project as an example.
See the details below.
I've created a new repository that I will use for providing examples of various scenarios and use cases for QEWD
https://github.com/robtweed/
Initially it contains a example of a scenario I'm often asked about: a set of REST APIs, with JWT support, implemented as a set of QEWD MicroServices, each of which uses Cache or IRIS running on a Windows system.
What I've provided is a detailed, step-by-step guide (with detailed explanations) of how to set up such a system.
The example shows a use case of REST APIs to:
- authenticate / login
- thereafter use a set of CRUD APIs to
Allow limited durability for demo and development IRIS-Docker-micro-Durability During development of a container based demo I found the need to access a fresh docker
an instance of IRIS image (e.g intersystems/iris-community:2020.2.0.199.0) over and over.
To bypass loading my code repeatedly, I developed this workaround.
The principle of a persistent IRIS database outside the container is unchanged.
But now the whole setup is moved into Dockerfile and docker-compose.yml

Using the IRIS native API for Node.JS was the opportunity to present
a MicroService operating in a Docker container.
A demo video is now also available to watch the demo in operation.
Instead of a utility you call directly on your IRIS host you now send a work-packages
to the MicroService as would typically do with System Interoperability (aka.ENSEMBLE):
of course, you have the option of more than one WebSocket Server.
Once the WebSocket Client Service has done its job you get back the result from it.
The advantage over the built-in WebSocket Client is, that all Network, Security,

As promised, here is Part 2 of our interview with Russ Leftwich! In this half, Adam Coppola talks with Russ about some of the InterSystems technologies that play a part in the concepts from Part 1, as well as some specific discussions about modern FHIR applications. After the interview with Russ, we were also joined by Jenny Ames to talk about the upcoming FHIR Dev Days. Check it out, and make sure to go subscribe to Data Points!
Hi Community!
We're pleased to invite you to the Online Meetup with the Winners of the 2nd IRIS Programming Contest! It's a virtual Meetup with some of the winners of the past InterSystems IRIS Online Programming Contest.
Date & Time: Friday, May 8, 2020 – 11:00 EDT
What awaits you at this virtual Meetup?
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.
Sometimes you have objects with an unknown number of fields, or perhaps hierarchically nested fields, for which, as a rule, you need to search.
Take, for example, an online store with diverse groups of products.Each product group has its own unique set of properties and has common properties as well.
After I loaded the intersystems/iam:0.34-1-1 image in local, I am trying to do the next step of configuration.
2) Configure your InterSystems IRIS instance
2a) Enable the /api/IAM web application
2b) Enable the IAM user
2c) Change the password for the IAM user
Do we need to change these settings in iris.cpf file? any inputs where we have to configure? I have IRIS 2019.1.1 installed in my machine.
Thanks,
Nag.
Hi again!
I logged into the demo IRIS again, and for some reason, today, I had an "Classpath is incomplete" warning message. The classpath is defined under quickstarts-multimodel-java. Here is the contents of the file :
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="lib" path="lib/intersystems-jdbc-3.0.0.jar"/>
<classpathentry kind="lib" path="lib/intersystems-xep-3.0.0.jar"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8"/>
See Part 1 here.
Now you have a good idea of what kind of indices you need for your class and how to define them. Next, how do you handle them?
(REMEMBER: Like any modifications to a class, adding indices in a live system has its risks – if users are accessing or updating data while an index is populated, they may encounter empty or incorrect query results, or even corrupt the indices that are being built.
I have just started to experiment with Using IRIS in Docker.
My first objective was to be able to enable global persistence within a Docker container. Using the following command I have managed to achieve this:
docker run --detach --publish 52773:52773 --volume /data/dur:/dur --env ISC_DATA_DIRECTORY=/dur/iconfig --name iris21 store/intersystems/iris-community:2020.1.0.199.0
Within this container, I have created a simple global:
for i=1:1:10 set ^tmp(i)=""
I then stopped and removed the container. On reloading and restarting the container the global has persisted.
However, I have just discovered
Hi Developers!
The second InterSystems Online Programming Contest is over. Thank you all for participating in our IRIS Competition!
As a result - 7 great apps! And now it's time to announce the winners!
An implementation of JSON-Patch in ObjectScript.
JSON-Patch (RFC6902) is a standard format that allows you to update a JSON document by sending the changes rather than the whole document. JSON Patch plays well with the HTTP PATCH verb (method) and REST style programming.
With zpm :
USER>zpm
zpm:USER>install objectscript-json-patch
Use it with this call :
Do ##class(Grongier.JSON.Utils).Patch(tDoc,tPatch)
Where :
The result will be tDoc p
Hi Developers!
We are going to establish a series of InterSystems IRIS Online Programming contests this year.
In March we started with ObjectScript CLI and here is the schedule of topics for the next few months:
All applications should be runnable with InterSystems IRIS in a docker container.

Over the Easter Weekend I touched on some deep learning classifier for Covid-19 Lungs. The demo result seems fine, seemingly matching some academic research publications around that time on this topic. But is it really "fine "?
Recently I happened to listen to an online lunch webinar on "Explainability in Machine Learning", and Don talked about this classification result at the end of his talk:

Hi Developers!
This is the digest of new solutions and applications submitted to InterSystems OpenExchange in April 2020!
FHIR Server and API Manager for MIT COVID-19 Challenge by Steven LeBlanc
This demo shows how InterSystems API Manager (IAM) can be used to view and test FHIR resources with InterSystems IRIS for Health. It comes pre-configured with a FHIR server, pre-populated with synthetic patient data. The new InterSystems API Manager (IAM) includes OpenAPI Swagger specs to quickly generate REST client code to work with many common FHIR resources.

Hi community,
This article to give a description of my small library JSON Filter.
Why JSON Filter?
Search, sort data are common operations.
But … How to do this with JSON data?
You can use a %DocDB, It’s a good way for storing JSON and index the main properties.
However, JSON document is very flexible. It isn’t always possible (and not recommended) to index each properties to process the wished queries. A manual processing on a data subset is may be required.
In my opinion, this is not a funny part of the job. It’s a repetitive code with many loops etc...
JSON filter allows to process these
Hi Developers,
New to machine learning? Watch this video on InterSystems Developers YouTube to understand the basic concepts of machine learning and how it provides value in applications around the world today:
During runtime I build an object which is essentially a wrapper over in-memory table:
| col1 | ... | colN |
| val11 | ... | valN1 |
| val12 | ... | valN2 |
I want to use this object as a part of INSERT or UPDATE queries, based on a value of some column (the main use case one of the columns is an ID value)
What's the best way to expose the object to SQL?
I have complete control over object class, so if I need to add something (or even change runtime internals), it's no problem.
Object may have different columns depending on runtime situation, but during one query execution the fields are
Hi everyone,

Hey Developers,
We're pleased to invite you to the "Best practices of in-platform AI/ML" webinar by InterSystems on April 28th at 11:00 EST/17:00 CET.
Hi Community,
We're pleased to invite you to join the upcoming InterSystems IRIS 2020.1 Tech Talk: API-First Development on May 5 at 10:00 AM EDT!
In this week's InterSystems IRIS 2020.1 Tech Talk, we'll discuss API-first development and how InterSystems is embracing this industry trend with our API Manager, and specifically with our FHIR offerings. First, we'll talk about InterSystems API Manager. This tool controls your web-based API traffic in a single location. You can throttle throughput, configure payload sizes and whitelist/blacklist IPs, among many other features.
FHIR stands for Fast Healthcare Interoperability Resources. Release 4 brings this HL7 standard to maturity, and the FHIR R4 support in InterSystems IRIS for HealthTM is big. You'll learn how to work with FHIR data in InterSystems IRIS, and see our developer portal in action, where you can access FHIR resources using the OpenAPI specification.
