What is Journaling?

Journaling is a critical IRIS feature and a part of what makes IRIS a reliable database. While journaling is fundamental to IRIS, there are nuances, so I wrote this article to summarize (more briefly than our documentation which has all the details) what you need to know. I realize the irony of saying the 27 minute read is brief.

How do you iterate over the array of namespaces returned in the result byref from the call below?

DO ##class(%SYS.Namespace).ListAll(.result)

Running "zw result" displays the namespaces (as individual subscripts in result) in the Terminal but I want to be able to programmatically iterate through each namespace name.

Hello Community,

In this article, I will outline and illustrate the process of implementing ObjectScript within embedded Python. This discussion will also reference other articles related to embedded Python, as well as address questions that have been beneficial to my learning journey.

As you may know, the integration of Python features within IRIS has been possible for quite some time. This article will focus on how to seamlessly incorporate ObjectScript with embedded Python.

Hi there,

I'm discovering IRIS and I need to POC the solution, with a constraint: containerization.
I'm used to deploy my apps in a Swarm cluster, and all my bind volumes are written on a GlusterFS volume.

The problem here, when I start my stack, the first log is:

[WARN] ISC_DATA_DIRECTORY is located on a mount of type 'fuse.glusterfs' which is not supported, consider a named volume for '/iris_conf'

And of course the deployment fails.

SYSTEM OBJ Export

I have a DOS batch file that calls *.scr script to back up an existing routine and upload the newly updated one.

I have a backup folder setup in C:\Users\[username]\Backup\ on each server, some with more recent versions of cache. The *.scr script calls on the command: $SYSTEM.OBJ.Export(routine,path) .

Hello every one, here in our company we are trying to develop a tool to help us in our "Code Review" that today is completely done for another developer.

So I need to develope a tool that reads a class/routine (Already done) and identify if in the current line there is some abbreviated command, that is against our policy of codification, for example:

s variable = "test"
d ..SomeMethod()

So in this cases I want to warn the original developer that the code has parts that need to change the "s" to "Set" and de "d" to "Do".

Hi there, I'm wondering if anyone has run into an issue with <FILEFULL> when building an image from the ISC image? Specifically what's happening in our build is we are pre-loading our codebase into the image to make deployments faster and setting up source control, etc. When loading our libraries however we get hit with a <FILEFULL>. The resource limits on docker are pretty beefy and when observing resources on both the machine and container level we don't hit any issues. Oddly, this only happens when using the ARM64 version.

I am trying to login to InterSystems image repository but it is not recognizing following credentials from ubuntu.

docker login https://containers.intersystems.com -u <username> -p <password>
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: Get "https://containers.intersystems.com/v2/": unknown: Bad credentials

The same credentials works via website.

during an upgrade, a customer wants to load custom schemas in a particular order.
For this, they renamed a file EPIC_MDM.HL7 to 1EPIC_MDM.HL7
Upon importing this file into their server using VSCode, the custom schema was renamed to 1EPIC_MDM.HL7 inside the <Category>

This is impacting the upgrade and they are looking for a way to import a custom schema without renaming the schema itself.

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.
