#InterSystems IRIS for Health

What is the recommended library for converting documents to pdf. Any suggestions welcome has anyone out there had a use case where they had to convert documents to pdf .What worked for them .I have asked WRC for the best practice and they have recommended that may be  a sale engineer might have an answer to this .

Hello everyone!

I have set up an EnsLib.REST.GenericService with an  EnsLib.HTTP.InboundAdapter which forwards the http requests received by a web app to my Business Process. 

I would like to parse HTTP multipart/form messages I am receving and be able to iterate over the various fields within the request body, accessing its content type and the content itself.

As far as I understand I should use the %Net.MIMEReader class which should return a list of %Net.MIMEPart, one for each field within the request. However if I do : 

Set mimeReader = ##class(%Net.MIMEReader).%New()
Set sc =

The first developer previews of InterSystems IRIS^® data platform, InterSystems IRIS^® for Health, and HealthShare^® Health Connect 2025.1 have been posted to the WRC developer preview site.  Containers can be found on our container registry and are tagged latest-preview.

These developer previews include the feature to migrate to IBM "Open XL C/C++ for AIX" 17.x compiler ensuring compatibility with future AIX builds as older compilers approach end-of-support. This migration focuses on the aixopenssl30 target, supporting SSL3 on AIX 7.2 and 7.3.

Hi Everyone!

The Certification Team of InterSystems Learning Services is currently developing an InterSystems ObjectScript Specialist certification exam. Earlier this month we reached out to our community for feedback that will help us evaluate and establish the contents of this exam. We are still currently accepting responses and would love to hear your feedback!

Please note that this is one of two exams being developed to replace our InterSystems IRIS Core Solutions Developer exam. You can find more details about the other exam, InterSystems IRIS Developer Professional exam, here. 

How do I

The IKO will dynamically provision storage in the form of persistent volumes and pods will claim them via persistent volume claims.

But storage can come in different shapes and sizes. The blueprint to the details about the persistent volumes comes in the form of the storage class.

This raises the question: we've deployed the IrisCluster, and haven't specified a storage class yet. So what's going on?

You'll notice that with a simple

kubectl get storageclass

you'll find the storage classes that exist in your cluster.

Since .Net has a unified package manager system (Nuget.org) why doesn't Intersystems create and add a nuget package (.nupkg) containing the InterSystems.Data.IRISClient.dll file.

This would make it easier for external .net developers to obtain the package for creating tools and/or applications that utilize Iris/Iris4Health

Can  Intersystems create a nuget package?

InterSystems worked closely with the Red Hat Insights team to implement a curated set of recommendations for system administrators to ensure the best experience running InterSystems IRIS on Red Hat Enterprise Linux (RHEL). Included with all RHEL subscriptions, the Insights service proactively identifies potential issues with monitored platforms and applications running on RHEL. Through our joint collaboration, Insights now watches for common scenarios that decrease the performance of IRIS in most cases and offers an InterSystems-approved recommendation for consideration.  

Ten recommendations

We currently use a combination of Ghostscript and ImageMagick to accomplish our PDF requirements.  These products are ceating memory/cpu issues when merging large PDFS.  I am trying to find out if Intersystems Reports can handle our requirements (see below).

Hi Community,

This is a detailed, candid walkthrough of the IRIS AI Studio platform. I speak out loud on my thoughts while trying different examples, some of which fail to deliver expected results -  which I believe is a need for such a platform to explore different models, configurations and limitations. This will be helpful if you're interested in how to build 'Chat with PDF' or data recommendation systems using IRIS DB and LLM models.

I have a flask application, its working locally. I also have a iris for health 2024.3 docker container front-ended with the iris nginx container.

I can configure the WSGI application with iris for health, give it a "url" (/flask or /csp/flask) but I cannot access the flask application. It looks like the url is not found within the nginx configuration. Is there any documentation or suggestion for configuration/enabling a flask app with a IRIS container front ended with the nginx container (provided by intersystems container registry) 

February 19, 2025 – Alert: SQL Queries Returning Wrong Results

InterSystems has corrected two issues that can cause a small number of SQL queries to return incorrect results. In addition, InterSystems has corrected an inconsistency in date/time datatype handling that may lead to different, unexpected – yet correct – results for existing applications that rely on the earlier, inconsistent behavior.

The first issue (DP-436825) only affects SQL queries that use a lateral join, either implicitly or explicitly, on an instance

Hi beloved members of the Community!

It is very common in the daily life of IRIS or Health Connect users that it is necessary to install new instances or update the ones they already have and in many cases it is not these same users who carry out the installation, but rather systems personnel who often do not take into account the particularities of the assignment of permissions necessary for the installation.

Hi,

I running an SQL so I can find the databases with the largest amount of free space. This is in case I can compact the databases.

However SQL cannot find the SYS.Database table.

Can someone please explain how to fix?

[SQL]TEST:%SYS>>select * from SYS.Database
ERROR #5540: SQLCODE: -30 Message:  Table 'SYS.DATABASE' not found

[SQL]TEST:%SYS>>  << entering multiline statement mode, 'GO' to execute >>
   1>>select DatabaseName, Directory, Size, Free, DiskFreeSpace
   2>>from SYS.Database

ERROR #5540: SQLCODE: -30 Message:  Table 'SYS.DATABASE'

FHIR repositories, applications and servers typically serve clinical data in small quantities, whether to return data about a patient, their medications, vaccines, allergies, among other information. However, it is common for a large amount of data in FHIR/JSON format to be requested to be used to load into Data Lakes, identifying study cohorts, population health, or transferring data from one EHR to another. To meet these business scenarios that require large extractions and loads of data, it is recommended to use the FHIR Bulk Data Access feature provided by HL7 institution.

The InterSystems

Hi all!Here I would like to share how we use vector search and GenAI with InterSystems technology.As an example, I'll describe BG-AppealAI project, which our company submitted to the InterSystems Vector Search, GenAI and ML Contest.BG-AppealAI application can write an appeal if you upload an insurance contract and the insurance company’s letter with a refusal to pay medical expenses.Of course, we are aware that at the moment AI has not reached such a level as to create ready-made legal documents.

Hi, this post was initially written for Caché. In June 2023, I finally updated it for IRIS. If you are revisiting the post since then, the only real change is substituting Caché for IRIS! I also updated the links for IRIS documentation and fixed a few typos and grammatical errors. Enjoy :)

In this post, I show strategies for backing up InterSystems IRIS using External Backup with examples of integrating with snapshot-based solutions. Most solutions I see today are deployed on Linux on VMware, so a lot of the post shows how solutions integrate VMware snapshot technology as examples.

IRIS backup

Urgently Looking for the following InterSystems Technology Skills:
(Must have Strong InterSystems (ISC) technology background and some Google cloud skills experience along with InterSystems IRIS).

1. Has 5+ years using InterSystems Object oriented scripting skills with FHIR experience on IRIS. HL7 and/or ADT and/or CCDA to FHIR.
2. 5+ years working experience on InterSystems IRIS
3. 5+ years having an Understanding on different Data standards including FHIR, HL7.
4. Different healthcare Data formats to be converted to FHIR using IRIS-InterSystems Platform.
5.

Just curious what the process is for debugging either a .py file that is uploaded to a specific namespace/location or a python classmethod defined in a .cls file.

My method can be run via the "Debug" breadcrumb but it doesnt hit breakpoints it just runs without a debugger. Also objectscript methods debug correctly

Hey everyone.

I came across some issues when setting up Freeze and Thaw batch scripts for use with VMWare in a Windows ecosystem, and I wanted to share what I found in the hopes it can help others. This was undertaken in an environment using Healthconnect 2019.1.x.

IRIS not up (2)

It seems that the sample script from the documentation in my my case would tell me that the environment was not running (despite it running). To correct this, I provided the filepath to the Mgr location as so:

c:\InterSystems\HealthConnect\bin\irisdb -s"C:\InterSystems\HealthConnect\Mgr" -U%%SYS

Hi all,

I have a passthru REST setup using EnsLib.HTTP.GenericService and EnsLib.HTTP.GenericOperation. Works well.

I am adding some logic to the Operation and for some scenarios I want to return an HTTP 40x response status code.

I create an httpResponse object within the Business Operation, but I can't figure out how to set the http response status code that is returned to my Posstman client that initiated the request. I set StatusCode=400, and StatusLine and ReasonPhrase properties - but when the ultimate requestor (Postman) receives the response back it is a 200 status code.

Hey everyone.

As I have been working with IRIS (nee Caché) for some time now, I decided to take a look at how I manage things like functions and scripts that may not belong to a single namespace or environment, but should still have a home.

I have taken to creating a github repo where I can keep track of a single .cls of "general functions" that I can then drop into an environment when required.

I have an operation using $ZF this operation ran and did not error but the job has been active and it can not be stopped I have tried stopping it from the front end and through the terminal using ##class(ENSLIB.Job).%New() Stop method. Now my production will not update even if I add a new item to the production I cannot update the item is there a way to force stop  this job.

I have a scenario where I send a GET request to a broker and receive a FHIR response. When I attempted to use the built-in InterSystems functions to convert this FHIR response into SDA, the transformation failed—likely because it is not a standard FHIR request.

How should I handle this situation? Is there a recommended approach to processing FHIR responses in this context?

Additionally, if I manage to convert the FHIR response into a request format, I noticed that the broker sends a Task resource.

I understand that InterSystems provides functions to facilitate transactions between FHIR and HL7 via the SDA segment. My question is:

• Does this transformation only work when InterSystems receives FHIR requests and converts them into HL7, or does it also support responses?
• Specifically, if our operation sends a GET request to a broker and receives a FHIR response, does InterSystems support transforming this response into an SDA segment automatically?
• Or should we manually parse and modify the response to handle it according to our needs?

What would be the best approach in this scenario?

Hi,

I'm trying to get a property from a class but I get an error:

SET status=##CLASS(Backup.Task).LastRunStatus
^
<CLASS PROPERTY>
 

Can someone please tell me the correct way to get the property?

The property is dexcribed here:

Thanks in advance.

The IKO allows for sidecars. The idea behind them is to have direct access to a specific instance of IRIS. If we have mirrored data nodes, the web gateway will (correctly) only give us access to the primary node. But perhaps we need access to a specific instance. The sidecar is the solution.

Building on the example from the previous article, we introduce the sidecar by using a mirrored data node and of course arbiter.

Hello Community,

Is it possible to track or determine where the global variable was set (routine or class) in a form of like label+offset^routine?

Hello,

I am new to InterSystems FHIR server implementation and in process of evaluating it. (R5)

I try to create a Task referencing a CarePlan resource as above.

I got the following error message and I wonder what could be the mistake as it used to work against another FHIR server implementation. (the referenced CarePlan resource does not exist but I guess that in this case the error code would be different?)
