You don't need to obtain an evaluation license directly, you just need to download the community edition of InterSystems IRIS for Health (IRIS For Health includes FHIR server capabilities). You can download installation kits here: Evaluate InterSystems Products or containers from docker hub with: 

docker run --name my-iris-health --publish 52773:52773 --publish 1972:1972 -d intersystems/irishealth-community:2025.3

The community edition is free to use, but has limits to prevent it being in production (e.g. max database size, max number of connections etc). 

Easiest way is with the community edition in a local docker container. Install docker and then run: 
 

docker run --publish 52773:52773 --publish 1972:1972 intersystems/iris-community:2025.3

You can also check out some of the dev templates which put this in a docker-compose file so you can clone a repo and run a working version with example code with just a couple of commands. You just have to make sure that in the Dockerfile it is pulling from version 2025.3 (or latest-cd). 

- ObjectScript Template

- Interoperability template

- Embedded Python Template
(theres more available on the open exchange)


Globals can be defined and accessed directly using a caret (^) symbol. For example, you can set or access a global with: 

// define a global by setting a value
set ^GlobalName = "Hello World"
// Access different sub-nodes 
set ^GlobalName(1, "foo") = "bar"
// You access the global in a similar way
write ^GlobalName // prints Hello World
// write all global values
zwrite ^GlobalName
// ^GlobalName = "Hello World"
// ^GlobalName(1,"foo") = "bar"

This can be useful for quickly saving values globally or looking up values.

I recommend having a look at the Using Caché Globals section of the Cache documentation because it has far more information on globals usage than could be relayed in a comment.

When I tested this morning, the FHIR Management part was available in the FHIR namespace before the 

do ##class(HS.Util.Installer.Foundation).Install("fhir")

process even finished running, so I don't think it should take any time for changes to propagate. I'm afraid I can't help further, it sounds like a frustrating issue but glad it seems to have resolved itself today.

Hi Robert, they should be available! I just checked with a fresh install and I can access them, but before doing so you need to create a FHIR enabled namespace. Here's the steps I took: 

Do a fresh install with docker: 

# Fresh docker install
docker run --name iris-for-health --publish 32782:1972 --publish 32783:52773 -d intersystems/irishealth-community:latest-em 

# Start IRIS terminal

docker exec -it iris-for-health iris session iris

Then install a new namespace using HS.Util.Installer.Foundation (I called it FHIR)

set $NAMESPACE = "%SYS"

do:'##class(%SYS.Namespace).Exists("fhir") ##class(HS.Util.Installer.Foundation).Install("fhir")

 With just this step, I can open the FHIR Server Configuration by going to the health tab of the management portal: 

Click FHIR: 

Then click FHIR Server Management to get to the FHIR Server UI with all the available features on the left hand panel:

I hope this helps! If not, you can also try using a docker-compose template here: pjamiesointersystems/Dockerfhir: Open repository for training with FHIR using IRIS for Health Community Edition

You can still install the InterSystems AutoML onto the normal IRIS Community edition with a pip install - its difficult to find in the documentation but its this: 


```

python3 -m pip install --index-url https://registry.intersystems.com/pypi/simple --no-cache-dir --target /usr/irissys/mgr/python intersystems-iris-automl

```

That way you no longer need a specific ML docker image to use AutoML.

I know I am late to comment here but no one has shared another workaround so I thought I would share mine! I have started using a browser extension on Microsoft Edge called Dark Reader - Microsoft Edge Addons which does a pretty decent job at turning any webpage, including community and management portal, to dark mode. It isn't always perfect, sometimes images don't work with a dark background or code blocks don't change colour, but is very easy to turn on and off when its needed.

It looks like the same extension is available for Chrome too, although I haven't tested it. I'll still advocate for real options in the management portal but this workaround works quite well for me!
