The new $system.external interface (aka "InterSystems External Servers") is used to call/integrate with external language code/libraries, it replace the old gateways (for example Java gateway) that required the import of proxy objects.

Note that the documentation for the old gateways has been removed from IRIS, so only the new $system.external interface is somewhat (i.e. insufficiently) documented.

Regarding the migration from old gateway to new  $system.external interface the documentation says:

External servers use an enhanced and simplified form of the older Dynamic Object Gateway technology.

Hi Developers, 

We'd like to highlight some outstanding projects created during the European Healthcare Hackathon 2023 in Prague. 
Participants were presented with nine real-world healthcare challenges by IKEM and AstraZeneca.  
InterSystems introduced to the participants an opportunity to use the FHIR repository and perform FHIR availability into their solutions by providing FHIR cloud services on AWS.

Meet the winners of our challenge:

1st place Čarodějové (PathoSync)

"The PathoSync software is a solid base for complex pathologist platforms. With the use of custom mapping, any laboratory can project their data into FHIR7 standard, which soon will be mandatory worldwide. This makes the digitalization process smoother. The connection with InterSystems assures quality and implements many healthcare features. Furthermore, the GDPR norms are strictly followed using the FHIR server based in Europe, so the usage of software follows the European standards."

Hi developers!

Today I would like to address a subject that has given me a hard time. I am sure this must have been the case for quite a number of you already (so-called “the bottleneck”). Since this is a broad topic, this article will only focus on identifying incoming HTTP requests that could be causing slowness issues. I will also provide you with a small tool I have developed to help identify them.

Our software is becoming more and more complex, processing a large number of requests from different sources, be it front-end or third-party back-end applications. To ensure optimal performance, it is essential to have a logging system capable of taking a few key measurements, such as the response time, the number of global references and the number of lines of code executed for each HTTP response. As part of my work, I get involved in the development of EMR software as well as incident analysis.  Since user load comes mostly from HTTP requests (REST API or CSP application), the need to have this type of measurement when generalized slowness issues occur has become obvious.

I have a message class define. But sometimes the RelatedItems fields is not returned. 

Parameter %JSONIGNOREINVALIDFIELD As BOOLEAN = 1;

Property RequestedTerm As AH.AHLIB.Custom.Symedical.Message.PostRelationResponse.termsRequested;

Property RelatedItems As list Of AH.AHLIB.Custom.Symedical.Message.PostRelationResponse.RelatedItems;
 

Respnse normally will return someting like this,

on ocassion the RelatedItems are not returned

have response context variable defined as the custom message type

How do I check in a BPL if there is no RelatedItems  in the response?
 

Artificial intelligence is not limited only to generating images through text with instructions or creating narratives with simple directions.

You can also make variations of a picture or include a special background to an already existing one.

Additionally, you can obtain the transcription of audio regardless of its language and the speed of the speaker.

So, let's analyze how the file management works.

Windows Subsystem for Linux (WSL) is a feature of Windows that allows you to run a Linux environment on your Windows machine, without the need for a separate virtual machine or dual booting. 

WSL is designed to provide a seamless and productive experience for developers who want to use both Windows and Linux at the same time**.

WSL 2 is the default distro type when installing a Linux distribution.

When trying to create a ML Model I ran into the problem, that AutoML apparantly isn't available on my IRIS instance.

I was able to use the following command successfully: CREATE MODEL ECLASSPREDICT PREDICTING (eClass) FROM SQLUSER.CRMSHOPARTIKEL

Then when trying to use TRAIN MODEL ECLASSPREDICT, I get the error from the image:

Roughly translates to : "-186: Modelprovider not available on this instance. #2822 %ML provider 'AutoML' is not available on this instance"

In my ML Configurations there are 3 standard configurations called %AutoML, %H20 and %PMML which I haven't changed.

IRIS External Table is an InterSystems Community Open Source Project, that allows you to use files, stored in the local file system and cloud object storage such as AWS S3 as SQL Tables.

It can be found on Github https://github.com/intersystems-community/IRIS-ExternalTable Open Exchange https://openexchange.intersystems.com/package/IRIS-External-Table and is included in InterSystems Package Manager ZPM.

To instal External Table from GitHub use:

Hello,

I have created a service in Node.js which interacts with IRIS using APIs. The current implementation uses basic auth. I want to implement OAuth 2, to make the communication between the node.js service and IRIS secure. I want my service to act as client and IRIS as Authorization and Resource server. I don't know how to do that. Anyone who has implemented OAuth using IRIS can you help me out or point me in the right direction on about how to implement it? 

Thank you for your help :)

I am trying to run the CSP server. But I get the error:

It worked once, but when I made some changes is displayed an error.
Also, a WEB page looks like this:

Did you face this issue? What is the reason for it?

I am looking for any examples on hoe to use http request to connect to S3, list buckets and loop thru them to download files recursively.

Hi folks, 

I made a solution (https://openexchange.intersystems.com/package/iris-pretty-gpt-1) and want to use it like 

CREATEFUNCTION ChatGpt(INpromptVARCHAR)
RETURNSVARCHARPROCEDURELANGUAGE OBJECTSCRIPT
{
    return ##class(dc.irisprettygpt.main).prompt(prompt)
}


CREATETABLE people (
nameVARCHAR(255),
city VARCHAR(255),
age INT(11)
)


INSERTINTO people ChatGpt("Make a json file with 100 lines of structure [{'name':'%name%', 'age':'%age%', 'city':'%city%'}]")

I know that a FUNCTION can only return one result.

What changes are to be made while customizing a FHIR server package when adding a new field. As provided in the documentation, we have a sample JSON package of favorite color and it is added in the table, but when we are adding a new field 'Insurance', it does not imports the package and says package already exists. We have three files of JSON 

1) Package.JSON

2) SearchParameter.JSON

3) StructureDefination.JSON 

What should we have to change for adding new field.

Here we are again with an article related to the Mirror!

In the previous article we saw how we could configure a Mirror between two IRIS instances, one acting as an active node and the other as a passive one. This mirroring system works on the transfer of a journal file that keeps the instance that works as a passive node continuously updated, but what happens if due to some communication failure or permissions of the journal file it is not transferred correctly?

The most common is that in this situation our Mirror remains unconfigured, in such a way that the passive node does not receive the

Welcome everybody!

In this short article I would like to present an example of use that surely many of you who work with IRIS as the backend for your web applications have faced on more than one occasion and it is how to send a file to your server from the frontend.

Generally the simplest way I have found to perform this task is to transform the file from the frontend to the Base64 format and make a POST call to our server attaching the Base64 obtained to a JSON message in which I indicate in a parameter the name of the file and in another the encoded data. Something similar to this:

Hello all,

I am trying to start java gateway and constantly getting an error in terminal:
"%RemoteService+3^%Net.Remote.Gateway.1 *%Exception.StatusException ERROR #5023: Remote Gateway Error: TCP error on port '55555', ensure there is an Object Gateway running on this port". I've checked jvm and it is running properly, telnet also is able to connect to the port.

I am attempting to setup my first OAuth2 client, as we are adventuring into the realm of making FHIR API calls to our EMR from HealthShare Health Connect. 

I have gone through and set up the Issuer Endpoint, and Client Configuration but now I want to test it and verify that the setup is correct. When I setup the Client Configuration, it would not allow me to use Discovery as it was saying I needed a "Client secret" but was not given one. So I set it up manually, thinking I hit all the information correctly.

However, if I go through the documentation and use GetAuthorizationCodeEndpoint, I am

Trying to setup my first OAuth 2 client to authenticate against Epic's Interconnect instance that is hosting FHIR/Web Service API's. Epic's documentation says the JWT request has to be sent as a POST request..

Does

and

automatically put the request into a POST request, or do I need to format a %Net.HttpRequest to POST?
