InterSystems HealthShare is a healthcare informatics platform for hospitals, integrated delivery networks (IDNs) and regional and national health information exchanges (HIE). HealthShare includes health information exchange, data aggregation, workflow, text analysis, and analytics technology.
GraphQL is a standard for declaring data structures and methods of data access that serves as a middleware layer between the client and the server. If you’ve never heard about GraphQL, here is a couple of useful online resources: here, here and here.
In this article, I will tell you how you can use GraphQL in your projects based on InterSystems technologies.
This is a 10-minute simple step-by-step guide on how to quickly set up various flavors of HealthShare docker containers from scratch on a Win10 laptop.
For example, we can build a couple of HealthShare "global edition vs UK Edition" demos as shown below.
There are a couple of frequently asked questions from HealthShare colleagues and partners:
I'm not saying that this is in anyway "best practices," but I'm in a peculiar situation where I need to restrict users from starting a "retired" Ensemble Production in a namespace that's been renamed. It's still an "Ensemble-activated" namespace; we need to keep it available for Ensemble Message Viewer access ... fortunately, only for a little while.
It's a bit of a hack ...
Open the Production class in Studio and add the following classmethod:
Hey everyone!
I had looked around a bit and couldn't find a native way to log queue counts in Ensemble/HealthShare so I wrote a quick task and persistent class to do it. Hope this saves someone a bit of time. Let me know your thoughts! Thanks!

Hello!
This article is a small overview of a tool that helps to understand classes and their structure inside the InterSystems products: from IRIS to Caché, Ensemble, HealthShare.
In short, it visualizes a class or an entire package, shows the relations between classes and provides all the possible information to developers and team leads without making them go to Studio and examine the code there.
If you are learning InterSystems products, reviewing projects a lot or just interested in something new in InterSystems Technology solutions — you are more than welcome to read the overview of ObjectScript Class Explorer!
This is more for my memory that anything else but I thought I'd share it because it often comes up in comments, but is not in the InterSystems documentation.
There is a wonderful utility called ^REDEBUG that increases the level of logging going into mgr\cconsole.log.
You activate it by
a) start terminal/login
b) zn "%SYS"
c) do ^REDEBUG

In previous"Part I" we have set up a deep learning demo environment. In this "Part II" we will test what we could do with it.
Many people at my age had started with the classic MLP (Multi-Layer Perceptron) model. It is intuitive hence conceptually easier to start with.
Keywords: Anaconda, Jupyter Notebook, Tensorflow GPU, Deep Learning, Python 3 and HealthShare
This "Part I" is a quick record on how to set up a "simple" but popular deep learning demo environment step-by-step with a Python 3 binding to a HealthShare 2017.2.1 instance . I used a Win10 laptop at hand, but the approach works the same on MacOS and Linux.
ˮ This is one of my articles which was never published in English. Let's fix it!
There are often questions surrounding the ideal Apache HTTPD Web Server configuration for HealthShare. The contents of this article will outline the initial recommended web server configuration for any HealthShare product.
As a starting point, Apache HTTPD version 2.4.x (64-bit) is recommended. Earlier versions such as 2.2.x are available, however version 2.2 is not recommended for performance and scalability of HealthShare.
Continuing on with providing some examples of various storage technologies and their performance profiles, this time we looked at the growing trend of leveraging internal commodity-based server storage, specifically the new HPE Cloudline 3150 Gen10 AMD processor-based single socket servers with two 3.2TB Samsung PM1725a NVMe drives.
I already talked about GraphQL and the ways of using it in this article. Now I am going to tell you about the tasks I was facing and the results that I managed to achieve in the process of implementing GraphQL for InterSystems platforms.
For Global Summit 2016, I set out to showcase a Reference Architecture I had been working on for a National Provider Directory solution with State Level Instances and a National Instance all running HealthShare Provider Directory and all running on AWS Infrastructure.
In short, I wanted to highlight:
Often InterSystems technology architect team is asked about recommended storage arrays or storage technologies. To provide this information to a wider audience as reference, a new series is started to provide some of the results we have encountered with various storage technologies. As a general recommendation, all-flash storage is highly recommended with all InterSystems products to provide the lowest latency and predictable IOPS capabilities.
The first in the series was the most recently tested Netapp AFF A300 storage array. This is middle-tier type storage array with several higher models above it. This specific A300 model is capable of supporting a minimal configuration of only a few drives to hundreds of drives per HA pair, and also capable of being clustered with multiple controller pairs for tens of PB's of disk capacity and hundreds of thousands of IOPS or higher.

Recently we supported a few NHS cases that required TIE (Trust Integration Engine) integration with the PKB service. Hence this article is meant to be a 10-minute quick guide to describe a demo solution (simple configurations and end-2-end implementation steps) for Health Connect (Ensemble) Integration with PKB (Patient-Knows-Best) service.
HealthShare HealthConnect and Information Exchange version 15.03 support import transformations from C-CDA 2.1 to SDA. You can find these transforms in your installation's csp/xslt/SDA3 directory. For general information about import transforms, see "CDA Documents and XSL Transforms in HealthShare" in Overview of Health Connect.
Among the enhancements to import functionality added in connection with C-CDA 2.1 support is the ability to preprocess your C-CDA input files prior to the transformation done for import.
I wanted to share a little tidbit which is in the Studio documentation (http://docs.intersystems.com/cache20152/csp/docbook/DocBook.UI.Page.cls?...) but many people who have been using the InterSystems Studio for a long time missed the addition of this *very* useful feature, and every time I mention this to an audience I see at least one face light up because of how excited they are to learn about it!
Within Studio, the Output pane (View -> Output) is actually misnamed. It is actually an Input/Output window which can be used to run Caché ObjectScript commands!
I needed to pass through a file with Ensemble but the operation wasn't writing some filenames as given because the EnsLib.File.PassthroughOperation 'sanitizes' filenames removing characters that are not valid on some operating

Prompted by this post about accessing a global at its original location after you have changed a mapping, here's a tip about one specific dropdown in Portal that's sometimes useful.
If your application is raising <PROTECT> errors and you're finding it hard to work out why, here's a way to get additional information.
First, if auditing is not already enabled, turn it on:
Then use "Configure System Events" (highlighted above) and locate the event named %System/%Security/Protect. In the screenshot below I used the Filter field to do this (type "protect" - highlighted below - and press TAB):
I only recently noticed the presence of a local database named CACHE alongside the more familiar CACHESYS, CACHELIB, CACHETEMP and CACHEAUDIT.
A bit of digging through the documentation archive led me to conclude that the CACHE database arrived in 2010.2, where the release notes say:
Prior to 2017.1, whenever I created a new namespace using Portal on Ensemble or HealthShare it was automatically configured to host productions. This used to irritate me, because sometimes I'm setting up a namespace (for example, to host our Deltanji tool) that doesn't need the extra Ensemble baggage.
Sometimes I observe people scrolling manually down to the bottom of the Console Log document when they want to see the most recent messages. So I want to draw attention to the handy link that does the job for you in a single click:
If you deal with multiple instances of Caché / Ensemble / HealthShare and sometimes have to work at the Terminal command prompt, did you know that you can easily add extra information to that prompt which may help prevent you running a command on the wrong instance?
During startup a Caché/Ensemble/HealthShare instance must consult a parameter file to get some information it needs at the early stages of startup. By default it uses the file called cache.cpf, but by adding an extra argument to the ccontrol start command you can make it use an alternative file.
