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.
Hi, everyone!
I want to share a personal project that started with a simple request at work:
Is it's possible to know how many Caché licenses we are using?
Reading other articles here in the community, I found this excellent article by David Loveluck
Hi Developers!
Recently we launched InterSystems Package Manager - ZPM. And one of the intentions of the ZPM is to let you package your solution and submit into the ZPM registry to make its deployment as simple as "install your-package" command.
To do that you need to introduce module.xml file into your repository which describes what is your InterSystems IRIS package consists of.
This article describes different parts of module.xml and will help you to craft your own.
I will start from samples-objectscript package, which installs into IRIS the Sample ObjectScript application and could be installed with:
zpm: USER>install samples-objectscript
It is probably the simplest package ever and here is the module.xml which describes the package:
<?xml version="1.0" encoding="UTF-8"?>
<Export generator="Cache" version="25">
<Document name="samples-objectscript.MODULE">
<Module>
<Name>samples-objectscript</Name>
<Version>1.0.0</Version>
<Packaging>module</Packaging>
<SourcesRoot>src</SourcesRoot>
<Resource Name="ObjectScript.PKG"/>
</Module>
</Document>
</Export>
In an ever-changing world, companies must innovate to stay competitive. This ensures that they’ll make decisions with agility and safety, aiming for future results with greater accuracy.
Business Intelligence (BI) tools help companies make intelligent decisions instead of relying on trial and error. These intelligent decisions can make the difference between success and failure in the marketplace.
Microsoft Power BI is one of the industry’s leading business intelligence tools. With just a few clicks, Power BI makes it easy for managers and analysts to explore a company’s data. This is important because when data is easy to access and visualize, it’s much more like it’ll be used to make business decisions.
Hi guys!
Was coding today with InterSystems IRIS in a docker container and decided to share with you the commands you may find useful in everyday coding.
# docker-compose build
command to build a container. Remember, it is useful if you have dockerfile in the repo.
if the build is successful call the following to launch it:
# docker-compose up -d
Find IRIS management portal on:
localhost:port/csp/sys/%25CSP.Portal.Home.zen?$NAMESPACE=%25SYS
where the port is what you set in docker-compose.yml - 52775 in this case.
Run the following if you want to launch a terminal session inside IRIS container:
# docker-compose iris iris session iris gfhj gj sdfdsfsdf USER>
And run the following to shut down the container:
# docker-compose down
Troubleshooting
Hi Developers!
InterSystems Package Manager (ZPM) is a great thing, but it is even better if you don't need to install it but can use immediately.
There are several ways how to do this and here is one approach of having IRIS container with ZPM builded with dockerfile.
I've prepared a repository which has a few lines in dockerfile which perform the download and install the latest version of ZPM.
Add these lines to your standard dockerfile for IRIS community edition and you will have ZPM installed and ready to use.
To download the latest ZPM client:
Hi Developers!
Often I find questions on how to install IRIS, connect to IRIS from IDE, setup the environment, compile, debug, maintain the repository.
Here below possibly the shortest way to set up all the environment and start development with ObjectScript on InterSystems IRIS.
Prerequisites
Make sure you have Git, Docker, and VSCode installed
Install Docker and ObjectScript extensions into VSCode

InterSystems Data Platforms products allow you to export and import security settings in two different ways. This article talks about those options:
- On the command line, using ^SECURITY
- Programmatically, using the Export and Import methods of classes in the Security package
You can export everything or individual sections of the security settings.
Since version 2019.2, InterSystems IRIS has provided their Native API for Python as a high-performance data access method. The Native API allows you to directly interact with the native IRIS data structure.
In this article, we will explore the development of an IRIS client for consuming RESTful API services that have been developed to the OData API standard.
We will be exploring a number of built-in IRIS libraries for making HTTP requests, reading and writing to JSON payloads, and seeing how we can use them in combination to build a generic client adaptor for OData. We will also explore the new JSON adapter for deserializing JSON into persistent objects.
Just wanted to share my Zabbix template for monitoring InterSystems IRIS on Linux servers.
It monitors irisusr (configurable) memory consumption:
Hi Developers!
Often we need to use relatively small arrays with constants, static arrays in algorithms, etc where we need to do something with each element of an array. There are several ways to deal with it in ObjectSctipt.
Previously I used to use globals, locals, PPG for this but not so long time ago figured out that %List is a way too handy.
Indeed, suppose we have an array of months and need to set up and use it in our code.
Since Caché 2017 the SQL engine has included new set of statistics. These record the number of times a query is executed and the time it takes to run.
Hello everyone,
After some work with IRIS we want to share our ToolBox-4-Iris with you.
What is this about?
The ToolBox-4-Iris is an API for IRIS with a collection of handy and useful tools - features that are not available in IRIS, but greatly simplify application development. To save time and effort on the "typical tools" that every developer needs. This includes additional classes, individual methods or even more efficient macros, which are described in the respective packages.
Content
Some time ago, InterSystems introduced the concept of %DynamicObjects.
This feature is a powerful tool that makes it very easy to convert any string of JSON text to objects and vice versa.
However, in the work that J2 Interactive is doing for our customers, there are a couple of things that "need some tweaking".
Hello everyone!
Recently I search how to convert Cyrillic to Latin with Cache Object Script, but didn't find anything and decided to write ourselves,
So here code:
Hi Developers!
Often when we develop some library, tool, package, whatever on InterSystems ObjectScript we have a question, how we deploy this package on the target machine?
Also, we often expect that some other libraries already installed, so our package depends on them, and often on some particular version of it.
When you code on javascript, python, etc the role of packages deployment with dependency management takes package manager.
So, I'm pleased to announce that InterSystems ObjectScript Package Manager available!
Our team is reworking an application to use REST services that use the same database as our current ZEN application. One of the new REST endpoints uses a query that ran very slowly when first implemented. After some analysis, we found that an index on one of the fields in the table greatly improved performance (a query that took 35 seconds was now taking a fraction of a second).
Object Synchronization is a feature that has been around for a while, since Caché days, but I wanted to explore a bit more how it works. I've always thought that database automatic synchronization is complex by nature but, for some particular scenarios shouldn't be so hard. So I considered a very simple use case (OK, perhaps the typical one, I'm not discovering anything... but if it's common and it works, it's good 
).
As you might have heard, we just introduced the InterSystems API Manager (IAM); a new feature of the InterSystems IRIS Data Platform™, enabling you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure. In case you missed it, here is the link to the announcement.
In this article, I will show you how to set up IAM and highlight some of the many capabilities IAM allows you to leverage.

Hello everyone,
I was first introduced to TDD almost 9 year ago, and I immediately fell in love with it.
Nowadays it's become very popular but, unfortunately, I see that many companies don't use it. Moreover, many developers don't even know what it is exactly or how to use it, mainly beginners.
IRIS provides us with anti login CSRF attack mitigation, however this is not the same as a CSRF attack, as login attacks only occur on the login form. There are currently no built-in tools to mitigate CSRF attacks on api calls and other forms, so this is a step in mitigating these attacks.
See the following link from OWASP for the definition of a CSRF attack:
https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF)
In many projects I was faced with storing hierarchical data (tree) in classes.
By tree, I mean such data, where each node has a parent node — an object of the same class.
Many examples of such data can be given. For example, a catalog in the online store. Suppose that this online store sells books, in this case, the category tree might look like this:
This tool is used to generate random read Input/Output (IO) from within the database. The goal of this tool is to drive as many jobs as possible to achieve target IOPS and ensure acceptable disk response times are sustained. Results gathered from the IO tests will vary from configuration to configuration based on the IO sub-system. Before running these tests ensure corresponding operating system and storage level monitoring are configured to capture IO performance metrics for later analysis.
Hi Developers!
This is the second post on the resources for Developers. This part is about Open Exchange
Using Open Exchange to Learn InterSystems
InterSystems Open Exchange is a applications gallery of tools, connectors, and libraries which InterSystems Developers submit to share the experience, approaches and do business. All the applications are either built with InterSystems data platforms or are intended to use for development with InterSystems data platforms.
If you are a beginner developer you can take a look at applications in Technology Example category. All the applications in this category come with open source code repositories, so you are able to run the samples and examples in a docker container with IRIS on your laptop or in the cloud IRIS sandbox. Examples:
I'm not saying that this is in anyway "best practices," but I'm in a peculiar situation where I need to restrict users from starting a "retired" Ensemble Production in a namespace that's been renamed. It's still an "Ensemble-activated" namespace; we need to keep it available for Ensemble Message Viewer access ... fortunately, only for a little while.
It's a bit of a hack ...
Open the Production class in Studio and add the following classmethod:
Hello community! I have to work with queries using all kinds of methods like embedded sql and class queries. But my favorite is dynamic sql, simply because of how easy it is to manipulate them at runtime. The downside to writing a lot of these is the maintenance of the code and interacting with the output in a meaningful way.
Hi Developers!
Recently I was asked, “How can a beginner in InterSystems technologies learn from InterSystems Developers community content to improve his developer skills”?
This is a really good question. It has several answers so I decided to write the post with the hope it could be useful for developers.
So! How to learn Intersystems Data Platforms(IRIS, IRIS for Health) from InterSystems Developers community content if you are a beginner?
As a developer, you have probably spent at least some time writing repetetive code. You may have even found yourself wishing you could generate the code programmatically. If this sounds familiar, this article is for you!
We'll start with an example. Note: the following examples use the %DynamicObject interface, which requires Caché 2016.2 or later. If you are unfamiliar with this class, check out the documentation here: Using JSON in Caché. It's really cool!
Hello everyone, it took some time but I'm finally getting things done again. Phew!
But for now, allow me to introduce a tool that I've been using frequently.
I call it Forgery.
