InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

InterSystems IRIS Minimum Supported CPU Models

When AMD published the x86-64 standard in 1999, little did they know they were inventing what would become the de-facto architecture for server CPUs. But the CPUs of today aren’t the same as ones produced 20 years back – as they have extensions for everything from Advanced Vector Extensions (AVX) to Hardware-Assisted Virtualization (VT-d).

InterSystems would like to take better advantage of these new extensions in upcoming versions of InterSystems IRIS. While our compilers are smart enough to create optimized code for many situations, some optimizations can only be turned on by explicitly cutting off support for processors that do not have that instruction set. Additionally, we are finding it increasingly difficult to maintain older CPU models to test on.

I am trying to replicate a REST call that I am able to make via a Postman call within a EnsLib.REST.GenericOperation.

It's been a while since I have messed around with trying to make external REST calls. When I execute my REST call, tSC is coming back with an error and I am trying to pinpoint why. I tried turning on ISCLOG = 5 but when calling the REST Operation from the Testing tool it is not logging anything to the ISC log.

Hi,

I've been working on a very basic Interoperability production in my computer. I followed one of the examples in the courses and created a TEST.FileRouterRoutingRule, but when trying to edit this rule, it takes me to the Rule Editor Login Page, where I can't get in (Not even with the _SYSTEM credentials) - Is this functionality unavailable in the community edition?

It helps to remove special characters, such as non-utf-8 characters either control characters or unicode characters from text that is not printable or can't be parsed by downstream systems.

There is also $C(32) in this condition; sometimes NBSP appears in the text and it will not be recognized by TIE, but downstream it displays as "?".

Hi Community!

We know that every developer has small side projects — apps where you experiment with new technologies, test ideas before implementing them in bigger solutions, or just build something fun for the sake of curiosity. But what if one of those projects could take you all the way to the InterSystems READY 2025?

We’re launching a unique opportunity: show us your passion, creativity, and love for IRIS, and win a free pass to the InterSystems READY + hotel accommodation!

The rules are simple: upload your fun IRIS-based side project to Open Exchange, and record a short inspirational video about why you should be the one to get the pass to THE event of the year and win!

Duration: April 21 - May 04, 2025

Prizes: hotel accommodation and free passes to the InterSystems READY 2025!

Hi, I am unsure how to remove this restriction; when I am performing dynamic SQL using ##class(%SQL.Statement).%ExecDirectNoPriv(, .query, args...)

It works fine, but the moment I add specific properties from the persistent class I am performing the select on into the WHERE clause, I get: ERROR #5540: SQLCODE: -99 Message: User UnknownUser is not privileged for the operation. Despite using %ExecDirectNoPriv, I've tried with prepared statement as well, exact same situation.

Hi Community!

Check out the new video on how to build the frontend UI by prompting it in lovable or (potentially) any spec first REST API in InterSystems IRIS:

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 ?

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:

  • You can improve the performance of the applications using an asynchronous approach.
  • It lets you decouple and reduce dependencies between services, microservices, and applications with the help of a data message mediator, meaning that there is no need for producers and consumers of exchanged data to know each other.
  • It allows the long-running processing of sent data (with the results) to be delivered after utilizing a response queue.
  • It helps you migrate from monolithic to microservices, where microservices exchange data via Rabbit in a decoupled and asynchronous way.
  • It offers reliability and resilience by making it possible for messages to be stored and forwarded. A message can be delivered multiple times until it is processed.
  • Message queueing is the key to scaling your application. As the workload increases, you will only have to add more workers to handle the queues faster.
  • It works well with data streaming applications.
  • It is beneficial for IoT applications.
  • It is a must for Bots’ communication.

The Good Old Days

The %Library.DynamicObject class has been in IRIS since before it became IRIS. If you have been using it since the Cache days, you may want to brush up on some of its changes.

In Cache 2018, the %Get method only had one argument. It was the key to retrieving from the JSON, meaning that if your JSON object called myObj, it would look like the following:

Global mapping priority

Hi,

If I map all globals with (*) to a database1, then would like to map specific only some globals eg. MYGLOB* to be located in a different database2, which mapping will override the other, so would all globals that starts with MYGLOB* be placed in database1 or 2?

Thanks

Minify XML in IRIS

In a project I'm working on we need to store some arbitrary XML in the database. This XML does not have any corresponding class in IRIS, we just need to store it as a string (it's relatively small and can fit in a string).
Since there are MANY (millions!) of records in the database I decided to reduce as much as possible the size without compressing. I know that some XML to be stored is indented, some not, it varies.
