#InterSystems IRIS

While working on getting JSON support for some Python libraries, I discovered some capabilities IRIS provided.

• JSON_OBJECT - A conversion function that returns data as a JSON object.
• JSON_ARRAY - A conversion function that returns data as a JSON array.
• IS JSON - Determines if a data value is in JSON format.
• JSON_TABLE function returns a table that can be used in a SQL query by mapping JSON.
• JSONPath support - is a query language for querying values in JSON.

I attended Cloud Native Security Con in Seattle with full intention of crushing OTEL day, then perusing the subject of security applied to Cloud Native workloads the following days leading up to CTF as a professional excercise. This was happily upended by a new understanding of eBPF, which got my screens, career, workloads, and atitude a much needed upgrade with new approaches to solving workload problems.

So I made it to the eBPF party and have been attending clinic after clinic on the subject ever since, here I would like to "unbox" eBPF as a technical solution, mapped directly to what we do in practice (even if its a bit off), and step through eBPF through my experimentation on supporting InterSystems IRIS Workloads, particularly on Kubernetes, but not necessarily void on standalone workloads.

Recently I got into a situation where a user had some roles, which granted additional roles, and so on.

As I did not understand where a particular permission came from, I wrote this code which gets an initial set of roles and unwraps them recursively, accounting for any repeats.

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:

This can be done with TRY-CATCH:

If you want to raise an arbitrary custom error in a TRY block, you can pass an exception with a throw as follows. In the following example, a custom error is raised if Stcount is less than 1.

Is there any mechanism already implemented in IRIS to prevent XSS exploits ?

This case happen when user input html/javascript content into fields and submit the page. If saved content is rendered as is, it's going to be executed by anyone visiting the page.

Hi, Support Team

I´m working with Cache for many years, currently i have running version cache-2018.1.7.721.0-win_x64.exe

However we are facing some compatibility/requirements challenges, in that way i´m hereby request your support to provide next version/build of Cache 2018.1 (e.g cache-2018.1.9.xxx.x-win_x64.exe )

Nevertheless , I already downloaded IRIS for testing purpose if can also provide trial/limited licence for detail testing will be apreciated.

Thanks in advance for your attention.

As we all know, InterSystems is a great company.

Their products can be just as useful as they are complex.

Yet, our pride sometimes prevents us from admitting that we might not understand some concepts or products that InterSystems offers for us.

Today we are beginning a series of articles explaining how some of the intricate InterSystems products work, obviously simply and clearly.

In this essay, I will clarify what Machine Learning is and how to take advantage of it.... because this time, you WILL KNOW for sure what I am talking about.

If you do not specify the option to remove the mirror attribute of the mirror database when deleting the mirror configuration, the database cannot be restored to a normal state and will be mounted read-only the next time it is mounted. To restore the database to a read-write state, you must remove the mirror attribute using the system routine ^MIRROR.

The procedure is as follows (execute in the %SYS namespace):

Hello,

I have installed the latest version of IRIS (without a web server) to replace my community version with a embeded web server.
I tried to connect Visual Studio Code to my namespace, but I am unable to do so. I keep receiving the message "Not found."
Here is my configuration:

The IRIS Installation Guide for Linux, Installation Directory section, says "Do not choose the /home directory, any of its subdirectories, or the /usr/local/etc/irissys directory." but there are no suggestions or any default.

What are your opinions on this? For example, I see that IRIS in a Docker container is installed in /usr/irissys. I'm wondering why that directory was chosen.

The official Linux filesystem docs say:
