We have an ObjectScript application that runs in Cache' and IRIS. Our typical installation involves a .zip file containing several files necessary for the installation and operation of the application. Steps are: expand the .zip file to a folder that will not be used by the application. Do ^%RI for the installation routines in the production namespace. Do the Installation routine. We have a customer that is trying to do a silent installation. He does not want to have to respond to any prompts on the installation.

Embedded python in InterSystems IRIS

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.

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".

So if you are following from the previous post or dropping in now, let's segway to the world of eBPF applications and take a look at Parca, which builds on our brief investigation of performance bottlenecks using eBPF, but puts a killer app on top of your cluster to monitor all your iris workloads, continually, cluster wide!

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.

eBPF: Tracing Kernel Events for IRIS Workloads

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.

An IRIS.DAT file was removed, as it was not needed anymore. But the database was mirrored, so it still shows up in the mirror monitor and database list. How can this be fixed? There is no backup of the .DAT file so it cannot be restored.

w ##class(SYS.Mirror).RemoveMirroredDatabase("/mydir/")

throws a protect error.

Hello,

I've recently updated the python version of a linux server running Red Hat Enterprise Linux 8.10 (Ootpa). We have an instance 2023.1 running there, and whenever I run the $System.Pyhthon.Shell() I can see it's still pointing to the old version. From within linux, it runs the latest one (we've change all the links to the new 3.11, so no scripts are broken).

So I guess the problem comes from the fact irispython is still compiled using old python version. So, how can I do to force IRIS to use the current version on the server, or update the irispython file?

I encountered an unexpected behavior while working with the $ZTIMEH and $ZTIME functions, specifically with times between 12:00 and 13:00. Here's what I observed:

W $ZTIMEH("08:50:38.975411826")
Output: 31838

W $ZTIME(31838,1)
Output: 08:50:38

This behavior is correct as $ZTIME returns the expected time of 08:50:38.

However, with the following example:

W $ZTIMEH("12:05:38.975411826")
Output: 338

W $ZTIME(338,1)
Output: 00:05:38

Currently we are exploring how we can allocate additional disk space to our current environment as we have seen a significant increase in growth of our Database files. Currently we have 3 namespaces, all with 1 IRIS.dat each that contains both the Global and Routines.

Since we have started down the route of everything within a single IRIS.dat file for each namespace, is it logical as we see growth to be able to split the current IRIS.dat for each namespace into a separate IRIS.dat for global and a IRIS.dat with for routines for each namespace in a Mirror environment?

Hello, I want to create PDF from HTML source. I found pandoc. I installed pandoc on IRIS container image. I created Interoperability production. I have setup REST service to receive HTML file in request body. I call pandoc command pandoc -o output.pdf input.html from a BPL process. I copy output.pdf file stream into response body. I save the response at the source. I get a file named output.pdf but it does not load in Acrobat. I suspect I am doing something wrong with headers (accept-encoding?) or maybe do I need to base64 encode the pdf file to transfer it via REST?
