IRIS has the likes of SQL inbound adapters for use with SQL gateways such as EnsLib.SQL.InboundAdapter to repeatedly query SQL Gateway connections. A scenario appeared as that we wanted to query an Internal database for some data but did not see an out of the box service for this. 

Have a Generic service that can poll internal SQL to work with downstream components.

What was not clear was "How do I send a result set downstream". It was not very clear as a resultset itself is not a peristent class and the object cannot be "Swizzled" an error like so

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. WSL 2 uses virtualization technology to run a Linux kernel inside of a lightweight utility virtual machine (VM). Linux distributions run as isolated containers inside of the WSL 2 managed VM. Linux

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:

git clone https://github.com/antonum/IRIS-ExternalTable.git

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 :)

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 th

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..

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

Case description

Let’s imagine that you are a Python developer or have a well-trained team specialized in Python, but the deadline you got to analyze some data in IRIS is tight. Of course, InterSystems offers many tools for all kinds of analyses and treatments. However, in the given scenario, it is better to get the job done using the good old Pandas and leave the IRIS for another time.
    For the abovementioned situation and many other cases, you might want to fetch tables from IRIS to manage data outside InterSystems’ products. However, you may also need to do things the other way around wh
