Hi folks!

Recently I was in need to setup a local FHIR server using IRIS For Health and I think I found the easiest and simplest way ever.

Just run in terminal these two lines below :

docker run --rm --name my-iris -d --publish 9091:1972 --publish 9092:52773 intersystemsdc/irishealth-community

and

docker exec -it my-iris iris session iris -U "USER" '##class(%ZPM.PackageManager).Shell("install fhir-server")'

And you'll have FHIR server running locally at http://localhost:9092/fhir/r4.

That's it!

The FHIR server will use the latest build of InterSystems IRIS for Health Community Edition and will deploy FHIR server from this app via IPM package in FHIRSERVER namespace.

This is for Mac, so please add in comments how it works in Windows.

This is a very short article as it is really easy to setup a local FHIR server with InterSystems IRIS for Health and IPM Package Manager.

I need to check if one class is a subclass of another (either direct or indirect).

For example:

Class Package.ClassA Extends %Library.Persistent
{
}

Class Package.ClassB Extends Package.ClassA 
{
}

Class Package.ClassC Extends Package.ClassB
{
}

In this example Package.ClassC is a subclass of 3 classes: %Library.Persistent, Package.ClassA, Package.ClassB.

So any of these checks should return 1:

Comparing Dates

Hi,

Any suggestion on how to compare dates? Below is my code but it does not seem to work.

USER>w $zdate(zdateh(x,8),1) > $zdate($zdateh(y,8),1)

When I set x to "06/01/2022" and set y to "04/01/2022" gives me an output of 1

When I set x to "09/01/2019" and set y to "04/1/2022" still gives me an output of 1

Any help is appreciated.

Thanks!

The first installment of this article series discussed how to read a big chunk of data from the raw body of an HTTP POST method and save it to a database as a stream property of a class. The second installment discussed how to send files and their names wrapped in a JSON format.

Now let’s look closer at the idea of sending large files in parts to the server. There are several approaches we can use to do this. This article discusses using the Transfer-Encoding header to indicate chunked transfer. The HTTP/1.1 specification introduced the Transfer-Encoding header, and the RFC 7230 section 4.1 described it, but it’s absent from the HTTP/2 specification.

10000 clients simultaneously

How InterSystems solutions handle C10k connections? ( https://en.wikipedia.org/wiki/C10k_problem )
For example, I want to create a social network on InterSystems platform.
In the scenario client (browser) => CSP Gateway => Cache can the Cache handle a large number of clients at the same time?
Quick analysis shows that CSP Gateway for each request opens a new TCP connection to Cache SuperServer (port 1972) allocating CSP session and license slot.

Restoring a backup

I have a client who' recently acquired a business that was running software that uses InterSystems IRIS as the database back end. In the process of preparing to have my company's software installed the client formatted the hard drive of his server, wiping out his data. I can't convert the data to MS SQL without a functioning database. He had a backup on an external drive, which I have copied down to my local machine. I loaded up a virtual machine with Windows 10 Pro, I installed Docker and IRIS. I started searching for explicit instructions for restoring the .CBK file, but I'm not hav

Hi! As a developer who was forced to move from Mac to Windows (temporary) I found some things a bit confusing. In this article I would like to talk about some tweaks I made to make my experience smoother. I think it can help not only Mac users who need to use Windows environment (for ex. in VMs), but also can help some Windows users to make some things more convenient. Of course, all the points are subjective, the best setup is one that works for you.

All the tweaks are related to Windows 10 as I don’t have an access to Windows 11 at the moment.

Web Crawling is a technique used to extract root and related content (HTML, Videos, Images, etc.) from websites to your local disk. This is allows you apply NLP to analyze the content and get important insights. This article detail how to do web crawling and NLP.

To do web crawling you can choose a tool in Java or Python. In my case I'm using Crawler4J. (https://github.com/yasserg/crawler4j).

This tells me that there is no timezone offset on this table/field:

Select TOP 1 GETDATE() as Now, TimeCreated FROM ens.messageheader ORDER BY TimeCreated DESC;

Hello All

I'm not sure what the best practice is for this. I have a DTL for returning ORUs back to a hospital in a different time zone. They have requested that various timestamps have the time zone offset added to the HL7 format (%q%k, I think). First, I just wanted to be sure the system was aware it was DST. I was able to determine if DST is in effect like this:

Designing valid hierarchies in DeepSee

When designing a hierarchy in DeepSee, a child member must have only one parent member. In the case where a child corresponds to two parents, the results can become unreliable. In the case where two similar members exist, their keys must be changed so that they are unique. We will take a look at two examples to see when this happens and how to prevent it.

Winning in GIS competition

GIS stands for Geographic Information System.
and it's not a typical arena for Caché. But it's definitely an environment with high data volume.

You see 3 major areas

- Visual front end:
A mature area well covered by a bunch of commercial and open source products.
No need for Caché there.
