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.

Parallel query hinting boosts certain query performances on multi-processor systems via parallel processing. The SQL optimizer determines when this is beneficial. On single-processor systems, this hint has no effect.

Parallel processing can be managed by:

  1. Setting the auto parallel option system-wide.
  2. Using the %PARALLEL keyword in the FROM clause of specific queries.

%PARALLEL is ignored when it applied to:

All pods are assigned a Quality of Service (QoS). These are 3 levels of priority pods are assigned within a node.

The levels are as following:

1) Guaranteed: High Priority

2) Burstable: Medium Priority

3) BestEffort: Low Priority

It is a way of telling the kubelet what your priorities are on a certain node if resources need to be reclaimed. This great GIF below by Anvesh Muppeda explains it.

Hey, So the title pretty much describes the question:
Where and How can i see the Stream that contains the response back to the client of a CSP application.

When the request is being processed and finished we return a response to the client - We do that by writing the data to a stream and that stream is sent back to the client.
I wanted to know how i can access the point right before that Data is actually written to the client back (meaning the place where the response is actually being send back, the last point of contact).

Died workers of WorkMgr

Started some work using WorkMgr, but then I noticed, that it stuck and does not get any responses from workers anymore

And I found that messages log contains logs about dead processes, why WorkMgr daemon did not restart died processes?

How to restart them without restarting IRIS

I'm having an issue with sending SMTP requests from a specific Microsoft 365 account to Gmail accounts. We can use other Microsoft 365 accounts, but something about this one specific account sending to Gmail fails. The error we get is just telling us that sending to the user xxxxx@gmail.com failed. In order to troubleshoot that, I'm looking for more detail than that.

Hey Developers,

Watch this video to discover an analytical approach to InterSystems IRIS encryption and how it interacts with storage compression and deduplication compared with storage-level encryption:

Minify XML in IRIS

In a project I'm working on we need to store some arbitrary XML in the database. This XML does not have any corresponding class in IRIS, we just need to store it as a string (it's relatively small and can fit in a string).
Since there are MANY (millions!) of records in the database I decided to reduce as much as possible the size without compressing. I know that some XML to be stored is indented, some not, it varies.

Hello everyone! This is my first post into the developer community and one that I hope is fairly simple to answer. In our environment we currently have 3 different Test environments for testing before migrating code to our Prod environment. Currently we are working on establishing a source control method using Git in house which has been a bit of a struggle. We have also had developers that had used different test and migration methods in the past which has caused some issues with keeping the different test environment in sync.

I'll preface this by saying I'm not sure if I found a bug or because I'm somehow misusing IrisVectorStore.

Basically I have code from the regular llama-index module working in my Python project which has SimpleDirectoryReader objects similar in nature to the demo I mentioned (https://github.com/intersystems-community/iris-vector-search/blob/main/d...). And I have other code working that can add new users to a SQL table in Iris.

Hi noble devs!

Just building a simple frontend->JSON->IRIS backend story, and figured that IRIS while importing via %JSON.Adaptor wants JSON fields to match property names, meaning even should match the case. Like:

{ name: "John", 

surname: "Doe"}

will have issues while saving the dynamic object to a class Sample.Person with:

SQL Host Variables missing ?

Host Variables are a rather common programming feature in many implementations of SQL.
A recent question in DC made me aware that in IRIS, Caché, Ensemble, ...
host variables just exist within embedded SQL

> You can supply host variables for Embedded SQL queries only. <

Related examples are included in the available Documentation

This is a description for a workaround if you don't / can't use embedded SQL.

A benefit of using Doxygenerate is that Doxygen does more than just HTML output. Tweak the Doxyfile that tells Doxygen what to do and you can easily create a PDF. Our example MARINA application yielded a 524-page PDF. Here's what page 94 looks like:

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.

Hello everyone,

I'm currently working on getting familiar with OAuth2, following this article. Since Part 2 involves using PKI, I decided to implement it as outlined in the article. However, I've run into an issue that I can't seem to resolve, and my searches on Google haven't yielded any useful results.

Here's a brief overview of what I've done so far:

Introduction

InterSystems IRIS allows you to build REST APIs using ObjectScript classes and the %CSP.REST framework. This enables the development of modern services to expose data for web apps, mobile apps, or system integrations.

In this article, you'll learn how to create a basic REST API in InterSystems IRIS, including:

I'm sure most of you are familiar with utility %SYS.MONLBL that is crucial when analysing code performance bottlenecks. It allows you to select a number of routines that you want to monitor at runtime and also specify what process(es) you want to watch. BUT, what if you do not know exactly, what process would execute your code? This is true with many web based (CSP/REST) applications today. You want to minimize the resource utilization on your production system that needs analysis. So, how about doing a small tweak?

The "Ask Developer Community AI" tool is an excellent resource for studying for the certification. I asked it about each topic that will be covered in the test and the results are below.
Note: I classified each answer by the assertiveness that I consider as good, average and bad.

Note 2: The article has 4 parts, each one for an exam area.

I ask ChatGPT periodically to produce ObjectScript or plain MUMPS code for string manipulation, or for implementing known algorithms etc. Occasionally, it does make mistakes or uses non-existing class members but generally not that bad. Is there any tutorial on the subject of using AI for coding, ideally specifically for ObjectScript/MUMPS? Any AI productivity advice, or tricks you are using, or another AI flavor?

Thanks in advance,
Anna

Mirror entered trouble state

Dear community, my company use intersystems iris, a old version of 2019 and centos 7.9

At the moment, we are faced with a rather strange luck of iris.

Every day during working hours, we receive a error that iris primary cannot transfer the journal to the backup node.

We have availability monitoring, these errors do not affect availability in any way, but I still wanted to analyze this error.

I understand that the severity of this error is only 1, but Can someone share a diagnostic method this error?

I am receiving the garbled text due to incorrect encoding or decoding. I tried to use the $zconvert function to convert it into the normal text but failed to do that. Can anybody suggest what I have to use to convert that into normal text?

Example: Garbled text that I am getting is "canââ¬â¢t , theyââ¬â¢re".
