Hi!
We are deploying the iris image in a Kubernetes environment and the cluster state is "Hung" , looking the alerts endpoint we get 2 alerts:

     "severity":"2",
     "message":"System appears to have failed over from node a69a9f137593"

Any idea / help where those are comming from and how to address them?

SetUp:

I have created the following Task to kick off a Ens.BusinessService to execute a SQL query and process the results

Class OSU.Workday.TerminationsTask Extends %SYS.Task.Definition
{

Parameter TaskName As STRING = "OSU - Workday Termination Update";

Method OnTask() As %Status
{
    #Dim sc as %Status
    #Dim ex as %Exception.AbstractException
    
    set sc = $$$OK

    try{
        // create the service
        #Dim tService As OSU.DataSource.Workday.TermService
        Set tServiceConfigName = "OSU.DataSource.Workday.

Hello to all the esteemed members of the InterSystems developer community in Spanish!

Although I often consult the developer community and have occasionally left a question here, this will be my first article, and what better occasion to do so than by participating in the 3rd technical article contest.

The topic I will cover in this article is the different tools that InterSystems IRIS provides us to optimize both the databases and the queries we run, as well as the new types of storage and data.

The problem

How many times have we migrated an IRIS Instance to another machine, maybe even another version, and after a few days realized we forgot that one SSL Configuration critical for a Business Operations to work? Or maybe a credential, or a lonely class in a package by itself?

The solution

The simple solution is to make a checklist¹. A checklist of the entities we have to move. But simple checklists on Word documents are often forgotten, or just ignored.

 Hi everyone,

I’m currently working with InterSystems IRIS and handling large datasets where some queries are starting to take longer than expected.

So far, I’ve tried basic indexing and reviewing query structures, which helped a bit, but I still feel there is room for improvement. My goal is to reduce response time, especially for frequently used queries in a production environment.

Hello Community!

We're pleased to invite you to the upcoming webinar in Hebrew:

👉Getting Started with OAuth 2.0 on InterSystems👈

📅 Date & time: March 25th, 3:00 PM IDT

I would like to understand the mechanism of "How data is written to the IRIS Database and in what sequence data is written to Journal, WIJ and IRIS database"

Is it possible to run a test case by classname instead of loading it from a directory?

I need to skip any directory loading completely since the directory with the source code does not exist.

Hello,

I have problem to get working my web application in IIS. On apache just works fine.

I had an app in wwwroot called test, there is index.html file where is tag

Already included in SystemPerformance

There are nfs disk commands (including nfsiostat) included with SystemPerformance, but disabled by default. Enable them by running:

$$Enablenfs^SystemPerformance()

Doing so will add the following nfs commands, for example, on Linux:

1. /usr/sbin/nfsstat -cn
2. /usr/sbin/nfsiostat [interval] [count]

Ensure the commands are installed and runnable from the OS :)

This can be subsequently disabled via $$Disablenfs^SystemPerformance()

Adding a generic command to SystemPerformance

Adding an arbitrary OS tool creates a "user" command under ^IRIS.

Issue

In the versions specified above, an instance may fail to start or may hang during operation if the database cache is greater than or equal to 2,097,152 MB (2 TB).

Hi Community,

We're super excited to share that we’ve just launched a new free, interactive tutorial designed especially for those who are new to InterSystems IRIS and looking for a clear, practical introduction to its core concepts.

🧑‍🏫 Data Models of InterSystems IRIS 🧑‍💻

Hello all,

I have a EnsLib.HTTP.GenericMessage inbound from a webhook with a GC stream.

My router is defined as the following:

Hi all.

I have a rather strange problem.

I've created a method in Python to create a vector for a vector search. So far, so good.

If I call this method from the terminal, it works correctly:

But if I make this same call from a code block in a Business Process, it gets stuck, doesn't respond, and throws the following error:

Does anyone know what's happening and how to fix it?

Thank you in advance

Hi community,

I've been working on a side project that I'd love to get some eyes on: a ground-up rebuild of the classic IRIS Production Monitor using a modern web stack. The existing ZEN/CSP-based portal does the job, but I wanted to explore what a contemporary, real-time version of it could look like.

What it is

A standalone Angular web application that connects to any Interoperability-enabled IRIS namespace and gives you a live view of your production — services, processes, operations, queues, event log, and message traffic — all in one screen.
