For practical reasons, it may be desirable that after a Linux server restart, the IRIS instance is automatically started.

Below you will find the steps to follow to automate the startup of IRIS during a reboot of the Linux server, via systemd :

1. Create an iris.service file in /etc/systemd/system/iris.service containing the following information

I found myself in the not-so-comfortable situation of working with a Linux system on which someone had accidentally disabled user access to the Linux shell. HealthConnect was running, servicing hundreds of interfaces. To resolve the access issue, though, we needed to bring the host down for the application of a fix.

Without the shell, the iris command is not available to control the instance, so we were faced with the potential of shutting down the server ungracefully. We wanted to avoid that if possible ...

Method or Class Method?

For programmers new to ObjectScript, one question will inevitably arise: “What is the difference between methods and class methods?” A typical answer would be: “A class method applies to a class, but a method applies to an instance of that class.” While that answer is correct, it lacks important information on how these methods di

I am trying to log certain program data in my ObjectScript REST class, to track down a bug I have. I am comparing two values at runtime, and one result does one thing, and another a different thing. Since this is a REST API class, I have no way of seeing in real time what the value is to debug. I cannot simply run the method in debug in Studio as it will not run properly being a REST class method, nor have the correct incoming header data to correctly replicate what is happening in the API at runtime when being hit by client apps.

I have a question about using OnInit() within a Ens.BusinessOperation.

When you include OnInit(), does OnInit() only execute when you start a Business Operation? Or does it execute OnInit () every time you send a REST request to the operation. I am trying to pinpoint when the best time is to execute the POST command to get the Token

I am needing to get a Bearer Token from a REST POST call and return the Authorization key prior to making the rest of the REST calls to pull down data.

One good thing about COVID-19 is that it taught people that online work and study are possible. I remember a week before the lockdown started, everyone said that working online was impossible, not secure, etc. And what do you know, it all became possible and "secure" in the blink of an eye. As with everything, it depends on whether a person is capable of organizing his or her day and their work or study attitude. Thus, I became a great believer in online education. As an associate professor who teaches databases, I find it beneficial to my schedule and students. One thing that studying online brings is flexibility. Another one is accepting third-party courses to grant credits to my students 😉

Considering that I'm teaching the basics of IRIS, I thought a new course, Getting Started with InterSystems IRIS for Coders, could be a relevant addition to my course. Therefore, I decided to follow the new Learning Path and see how it corresponds to my Syllabus and how many ECTS credits I can give for finishing it.

Hi all,

Some days ago, I've seen a youtuber talking about how to create a neural network (sorry, is in spanish)

Using the FHIR DEMO, I have pieced together how to make a FHIR Request using OAuth against an External FHIR Repository. When I execute the Patient search (HS.FHIRServer.Interop.Request), I get a HS.FHIRServer.Interop.Response that has a Quick Stream ID, which I then use to convert the Quick Stream to a JSON Dynamic Object. if I do a trace on the Raw JSON Object, I am able to pull out single elements, however I want to pull the raw JSON into a defined Class Structure.

Polybase and IRIS

Hi all, I am trying to use Polybase in SQL Server 2019 to access an external Cache/IRIS Database. I have followed the initial steps of enabling Polybase, creating a Database, DB scoped credential and then an External Data Source. These steps have not caused any issues and appear to be successful, I am using the same DSN we use for a Linked Server connection that works normally. I am running into an Error when trying to Create an External Table. The error is a generic Native Code 469 "Driver Not Capable".
