How many times have you had to receive or generate a JSON and wished you could work on it using DTLs without having to deal with DynamicObjects trying to remember the name of each field? Do you want to break down and make your giant JSON file more digestible?
In my case, never, but I thought that someone might find it useful to have a feature that captures your JSON and breaks it down into a series of ObjectScript classes that you can work with more easily and conveniently.
Well then...behold JSON2Class in all its glory!

Some concepts make perfect sense on paper, whereas others require you to get your hands dirty. Take driving, for example. You can memorize every component of the engine mechanics, but that does not mean you can actually drive.
You cannot truly grasp it until you are in the driver's seat, physically feeling the friction point of the clutch and the vibration of the road beneath. While some computing concepts are intuitive, Intelligent Agents are different. To understand them, you have to get in the driver's seat.
As mentioned in the previous article, it is possible to configure the way you wish your collections to be stored and queried in SQL.

To set this up, you will need to use the following field parameters and settings:
In InterSystems IRIS, when you compile a persistent class, you automatically get a SQL table. Sometimes, there are situations that require having a slightly (or not so slightly) different names/options in SQL compared to Object model. Here are some of the settings that you can change to make it happen.
They define the "Face" of your class when it appears as a table in the SQL catalog.
SqlTableName allows you to change the name of SQL table that holds objects from your class. This is especially useful, when your class name uses reserved SQL words in a name, e.g. Group.

InterSystems Learning Services is working to identify and create libraries of high-quality learning resources for third-party technologies, platforms, and systems that are part of, integrated with, or commonly used with InterSystems products and technologies. we don't create content for these ourselves, but want to support our clients, external and internal, in learning about them and how to use them.
A question that quickly arises when configuring IAM (aka Kong Gateway) is how many routes should be created to reach all the business objects in an IRIS API.
A common mistake is to create one route per business object, unnecessarily multiplying the number of routes.
Let's take the example of the Supply Chain Orchestrator Data Model API:
This is the second part of an article pair where I walk you through:
As mentioned the goal is to give you a smooth “first run” experience.
If you already know Java (or .Net) and perhaps also have used other document databases (or looking for one), but you are new to the InterSystems world, this post should help you.
InterSystems IRIS Cloud Document is a fully managed document database that lets you store JSON documents and query them with familiar SQL syntax, delivered as a cloud service managed by InterSystems.

Hi folks!
Is there any way to know the text of the SQL queries executed against the IRIS server?
My case: I have an SQL class query with a few parameters and and some combination of values causes unexpected results.
It'd be great if I could just copy the query from some log of queries done vs my IRIS the server. Cannot find it easily, though. Any advice?
Modern platforms usually treat observability as three core signals:
OpenTelemetry (OTel) is the standard way to produce and ship all three signals. This article explains a practical setup for InterSystems IRIS running in Docker Compose, with a full local observability stack:
RabbitMQ is a message broker that allows producers (those who send a data message) and consumers (those who receive a data message) to establish asynchronous, real-time, and high-performance massive data flows. RabbitMQ supports AMQP (Advanced Message Queuing Protocol), an open standard application layer protocol.
The main reasons to employ RabbitMQ include the following:

How can we handle JSON boolean types in IRIS?
I'm having a UI sending me a JSON payload as:
{
"id": 1,
"strprop": "string",
"boolprop": true
}The class is
MyPackage.MyClass Extends (%Persistent, %JSON.Adaptor)
{
strprop as%String;
boolprop as%Boolean;
}And I'm trying to update an instance of a MyPackage.MyClass and I'm getting a datatype-related error, something like %JSONImportInternal+269...
How am I supposed to deal with booleans in JSON with IRIS and ObjectScript? Any best practice advices?
There are numerous excellent tools available for testing your REST APIs, especially when they are live. Postman, various web browser extensions, and even custom ObjectScript written with %Net.HttpRequest objects can get the job done. However, it is often difficult to test just the REST API without inadvertently involving the authentication scheme, the web application configuration, or even network connectivity. Those are a lot of hoops to jump through just to test the code within your dispatch class. The good news is that if we take our time to understand the inner workings of the %CSP.REST class, we will find an alternative option suited for testing only the contents of the dispatch class. We can set up the request and response objects to invoke the methods directly.
Hi, now I would like to continuous on the topic that we talk about previously
Using Postman for testing the OAuth2.0 of the InterSystems FHIR repository - Part1
Question 1: Where is my client_id and client_secret come form?
Short answer: Authentication Server.
If you don't have an Authentication Server, you may set up one as following
Provide the hostname (the host must support Https), at least 1 grand type (we choose client credential here), and SSL/TSL configuration
Sometimes customers need a small IRIS instance to do something in the cloud and shut it down, or they need hundreds of containers (i.e. one per end user or one per interface) with small workloads. This exercise came about to see how small an IRIS instance could be. For this exercise we focused on what is the smallest amount of memory we can configure for an IRIS instance.Do you know all the parameters that affect the memory allocated by IRIS ?
These are the different buckets that affect memory allocation by IRIS and its corresponding parameters:
What is JWT?
JWT (JSON Web Token) is an open standard (RFC 7519) that offers a lightweight, compact, and self-contained method for securely transmitting information between two parties. It is commonly used in web applications for authentication, authorization, and information exchange.
A JWT is typically composed of three parts:
1. JOSE (JSON Object Signing and Encryption) Header
2. Payload
3. Signature
These parts are encoded in Base64Url format and concatenated with dots (.) separating them.
Structure of a JWT
Header

Hi developers!
There is a very neat variable in IPM ${ipmdir} that lets packages be installed on a particular IRIS server and ensures that the data and resources they bring don't mess around as ${ipmdir} variable during the installation transforms into:
iris installation dir/ipm/package_name/version/whatever_you_install_here
It is very convenient, e.g., to bring some data and resource files that can be useful during the installation setup, e.g., via FILECOPY. Indeed, suppose you bring some csv_file, e.g. titanic.csv via FILECOPY as:
<FileCopy Name="data/titanic.csv" Target="${ipmdir}data/titanic.csv"/>or even the whole folder of data in the source code repo into the package:
<FileCopy Name="data/" Target="${ipmdir}data/"/>And in the case of Iris in Docker it resides in:
/usr/irissys/ipm/package_name/1.0.0/data/titanic.csv
This is all great, but is there any way for the installed code to determine the location of the data files? It'd be neat to let the installed app know somehow where is the data that came with it? Could it be the method in the IPM client that will resolve ${ipmdir} for the app?

We are a group of interface analysts in a healthcare setting, running IRIS for Health 2024, having upgraded over time from an old ENSEMBLE environment. We have been working on a wish list of development goals, but are having trouble finding the correct, best practice method/path for getting to what we envision.
If you want to generate JWT from x509 cert/key, any operation (including reading) on %SYS.X509Credentials requires U on %Admin_Secure resource.%Admin_Secure is required because %SYS.X509Credentials is persistent, and it's implemented this way to prevent all users from accessing private keys.
If %Admin_Secure resource is not available at runtime, you can use the following workaround.

I have a business service that actively reads data from a remote Postgres database. OnProcessInput opens a XDBC (actually JDBC) connection, executes an SQL query, fetches several thousand rows, iterates the resultset, and closes the connection. On each iteration I also need to update each source row in the remote database using PreparedStatement.
In other words, in every OnProcessInput call I have a long running SELECT statement and several thousands small UPDATE statements.
The problems I'm facing are:
