I'm working on FHIR project and using this code to convert an incoming request to FHIR 

Method OnRequest(request As HS.FHIRServer.Interop.Request, Output response As HS.FHIRServer.Interop.Response) As %Status

{

    #dim tSC As %Status = $$$OK

    Try {

        // Process incoming request

        set stream = ##class(HS.SDA3.QuickStream).%OpenId(request.QuickStreamId)

        set bundle = ##class(HS.FHIR.DTL.vR4.Model.Resource.Bundle).FromJSON(stream,"vR4")

It's working ok but when I include a realistic PDF in a FHIR Binary resource (contained in the Bundle) I get a MAXSTRING

Anyone know how to subtract three hours from $ZDATETIME($HOROLOG,3)?

If $ZDATETIME($HOROLOG,3) returns 2025-01-30 10:17:04, I would like $ZDATETIME($HOROLOG,3) - 3 hours to return 2025-01-30 07:17:04

Hi,

I can start IRIS terminal using iris Terminal <instancename>, but can I open up Studio & SMP in Linux?
Thanks

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 .

How would I go about getting the adapter state of this business operation? Ideally, I would like to provide the config item name to a method—in this case, 'T_SPM_SIU'—and have the method return the adapter's state, such as "Disconnected" or "Connected," along with its status.

Hi Community!

Welcome to Issue #19 of the InterSystems Ideas newsletter! This edition highlights the latest news from the Ideas Portal, such as:

We have some ObjectScript code in a custom business process:

When Log Trace Events is ticked on the business process in the Production view in the management portal, the argument is obviously computed.

Our question is whether the argument is computed when Log Trace Events is not ticked? Don't want to accidentally include something in a $$$TRACE() statement that takes enough computation to make a performance difference when released to production, even though the final output is not written to the event log.

A more general question is whether its possible to check the Log Trace Events status from

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 =

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.

⏯ FHIR Performance Benchmarking @ Global Summit 2024

While upgrading old Ensemble and Health Connect applications to V 2024.1 we are installing many webgateways since the private webserver is deprecated.

Configuring the "Default Parameters" we can determine the "Event Log Rotation Size" but not the count of preserved logfiles. So even if the webgateway cuts the logs in pieces they could fill up the disk space entirely for there seems to be no cleanup-job for old logfiles.

What is the recommended way to deal with this situation?

Do I have to create a schduled job on OS-level?

Hi Dev Community

I thought i would share a little method I knocked together to traverse and compare 2 JSON objects for basic equivilance.   I'm currently working on some data migration, and wanted a basic sanity check to validate that the JSON output is basically equivliant between the old and new, excluding a few things like timestamps.  

It's a basic little recurvsive method, that will bubble up any differences over a nested structure.   It's very low tech, as that's all I need it to do, but I thought it might be useful for others?

It can accept a source and target JSON object or array, and

Hi folks!

I'm building a very simple REST API.

But before testing it via a Web Server what I want to make sure that REST API methods work in principle.

Is it an easy way to "fake" the web-server request and get a result e.g. of the method with signature like that?

ClassMethod GetAllRecords(pRequest As %CSP.Request, pResponse As %CSP.Response) As %Status

e.g. calling it in Terminal?

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?

Hi Community,

I've created a method in my File Service to do a cleanup for every file load. Currently, I've set it to delete data when LastUpdated date is greater than maxdate. However, I want to do a cleanup for every new file load. Any suggestions or advice on how to do this? Thanks!

Method Cleanup()
{

   Set tMaxDate = ""
   &SQL(SELECT Max(LastUpdated) into :tMaxDate
   FROM MC_Table_Data.Patient) 
 

   &SQL(DELETE MC_Table_Data.Patient WHERE LastUpdated<:tMaxDate)
}

Hello,

So i want to use the INSERT OR UPDATE command so i can update a COUNTER for a given name:

INSERT OR UPDATE myTable
SET name='Omer',  counter = counter + 1;

as you can see with the above code - if the row is non-existent then we get an error because COUNTER is NULL! 
I tried the following to fix this but all have failed:

INSERT OR UPDATE myTable
SET name = 'Omer', 
    counter = CASE 
        WHEN counter IS NULL THEN 1 
        ELSE counter + 1
    END

INSERT OR UPDATE myTable SET name='Omer',counter = COALESCE(counter + 1, 1)

INSERT OR UPDATE myTable SET name='Omer',counter =

Hello Community:

Let's go with the last article on how to record yourselves for the Article Contest video bonus.

I'm not going to go into how to do very specific things in editing because it varies depending on the program you use. The keyboard shortcuts and menus are different, but the concept is the same. You are going to use a programme to organise the recorded material, remove the excess and give it structure. Many of these softwares are free (Capcut, Canva and if I'm not mistaken DaVinci had a free version). I've been editing with Adobe Premiere for almost ten years now (wow, I'm getting old), so if you have any questions about this software, feel free to write to me.

Here are some concrete tips:

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.

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.

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)

sometimes the response seems to not have the "Transfer-Encoding:chunked" but sometimes it does, what may casue this behaviour?
