Over the past couple of months, I have been working on the SMART on FHIR EHR Launch to test the capabilities of IRIS for Health using two open-source apps from CSIRO: SMART-EHR-Launcher and SMART Forms App. This journey has been incredibly interesting, and I’m truly grateful for the opportunity to work on this task and explore more of IRIS for Health’s potential.

So being forced to use VSCode out of the box for a new Community install I've hit a small problem, documentation hasn't helped and its a simple problem.

How do I enable auto complete and the property viewer in creating a new .MAC?

So I've created "test.mac" and 'assume' can't remember the method name to open a file (for example), typing

"s f=##class(%Library.File). " in Studio would bring up the methods of %Library.File so I could click the appropriate one, VSCode does not do this (and also didn't show the classes under %Library).

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:

All pods are assigned a Quality of Service (QoS). These are 3 levels of priority pods are assigned within a node.

The levels are as following:

1) Guaranteed: High Priority

2) Burstable: Medium Priority

3) BestEffort: Low Priority

It is a way of telling the kubelet what your priorities are on a certain node if resources need to be reclaimed. This great GIF below by Anvesh Muppeda explains it.

I am a volunteer at a nonprofit that is attempting to connect to a product that uses InterSystems Cache (Clinisys LIMS). I have not used this database before, but I have used many others (MS-SQL, Oracle, etc.). I am hoping IRIS is compatible enough with Cache for this project.

I downloaded IRIS. I learned about Terminal [IRIS]. Using it I was able to create a new table, insert data, and retrieve it. I also used the Management Portal to query the new table. It also returned the data.

Hi,

I recently had a company-enforced OS upgrade, and ever since going from mac OS 14.x to 15.x, I am currently having issues with SSL in IRIS.

An ARM (M3 pro) machine running OS 15.2, with the latest Docker Desktop (at the time of writing, 4.37.0). The Docker container runs IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2022.1.2 (Build 574_0_22161U). This container has not changed.

I’m trying to connect to an InterSystems Caché database from my local development environment using an IPv4 address. Most examples I’ve found show how to connect using the ODBC driver with the localhost or the default IP address (127.0.0.1). However, I want to know how to connect using my local IPv4 address.

Here’s what I need help with:

The task is to find all globals that are referenced in certain routines. I could search for ^ using class(%Studio.Project).FindInFiles but that would also find ^ in comments and function calls. I can distinguish between a global and a function call visually, but it would be lovely to be able to skip function calls programmatically. Is it possible?

Are you familiar with SQL databases, but not familiar with IRIS? Then read on...

About a year ago I joined InterSystems, and that is how IRIS got on my radar. I've been using databases for over 40 years—much of that time for database vendors—and assumed IRIS would be largely the same as the other databases I knew. However I was surprised to find that IRIS is in several ways quite unlike other databases, often much better. With this, my first article in the Dev Community, I'll give a high-level overview of IRIS for people that are already familiar with the other databases such as Oracle, SQL Server, Snowflake, PostgeSQL, etc. I hope I can make things clearer and simpler for you and save you some time getting started.

When working with InterSystems IRIS, database developers and architects often face a critical decision: whether to use Dynamic SQL or Embedded SQL for querying and updating data. Both methods have their unique strengths and use cases, but understanding their performance implications is essential to making the right choice. Response time, a key metric in evaluating application performance, can vary significantly depending on the SQL approach used. Dynamic SQL offers flexibility, as queries can be constructed and executed at runtime, making it ideal for scenarios with unpredictable or highly variable query needs. Conversely, Embedded SQL emphasizes stability and efficiency by integrating SQL code directly into application logic, offering optimized response times for predefined query patterns.

In this article, I will explore the response times when using these two types of SQL and how they depend on different class structures and usage of parameters. So to do this, I'm going to use the following classes from the diagram:

Here at InterSystems, we often deal with massive datasets of structured data. It’s not uncommon to see customers with tables spanning >100 fields and >1 billion rows, each table totaling hundred of GB of data. Now imagine joining two or three of these tables together, with a schema that wasn’t optimized for this specific use case. Just for fun, let’s say you have 10 years worth of EMR data from 20 different hospitals across your state, and you’ve been tasked with finding….

It's been a while since the new UI for Productions and DTL was published as a preview and I would like to know your opinions about it.

WARNING: This is a personal opinion, totally personal and not related with InterSystems Corporation.

I'm going to start with the Interoperabilty screen:

Production screen:

The style is sober and without frills, following the line of cloud services design, I like it.

How to create a signed JWT

I need to create a JWT to connect to EPIC FHIRserver sandbox.

https://fhir.epic.com/Documentation?docId=oauth2&section=BackendOAuth2Guide

You will generate a one-time use JSON Web Token (JWT) to authenticate your app to the authorization server and obtain an access token that can be used to authenticate your app's web service calls. There are several libraries for creating JWTs. See jwt.io for some examples.
