I am exploring a way to make IRIS an immutable system where the production/operation IRIS is never changed. Changes are only made in Development, and then the "version" is copied to production/operation and stated.

For this to work, I will need data (objects) on a file share and the IRIS system on different systems. When the "new" version spins up, it will use the latest data.

I do not know if I can or how to separate "object data" from classes and code.

Introduction to Kubernetes

In this article, we will cover below topics:

  • What is Kubernetes?
  • Main Kubernetes (K8s) Components


What is Kubernetes?

Kubernetes is an open-source container orchestration framework developed by Google. In essence, it controls container speed and helps you manage applications consisting of multiple containers. Additionally, it allows you to operate them in different environments, e.g., physical machines, virtual machines, Cloud environments, or even hybrid deployment environments.

Anyone here know if the Implementation Partner program is still open, and if so, is there anyone we can contact to get more details? I've tried reaching out via the form on the website, I've called and left a message, and then I called and talked to someone a few weeks ago who said they would "forward my info over", but we still haven't heard back from anyone. We just want to get more info on what it entails, but can't seem to get in touch with anybody to talk about it.

What I find really useful about IRIS when teaching my subject of Postrelational databases is the fact that it is a multi model database. Which means that I can actually go into architecture and structure and all that only once but then show the usage of different models (like object, document, hierarchy) using the same language and approach. And it is not a huge leap to go from an object oriented programming language (like C#, Java etc) to an object oriented database.

However, along with advantages (which are many) come some drawbacks when we switch from object oriented model to relational. When I say that you can get access to the same data using different models I need to also explain how it is possible to work with lists and arrays from object model in relational table. With arrays it is very simple - by default they are represented as separate tables and that's the end of it. With lists - it's harder because by default it's a string. But one still wants to do something about it without damaging the structure and making this list unreadable in the object model.

So in this article I will showcase a couple of predicates and a function that are useful when working with lists, and not just as fields.

IRIS Document Database (DocDB)

InterSystems IRIS Document Database (DocDB) offers a flexible and dynamic approach to managing database data. DocDB embraces the power of JSON (JavaScript Object Notation), providing a schema-less environment for storing and retrieving data.

It is a powerful tool, enables developers to bypass a ton of boiler plate code in interaction with existing applications, serialization, pagination and integration. the seamless flow of DocDB with Interoperability Rest services and operations, gives a big leap in API production and management.

for full DocDB documentation Here. in the context of this article i will showcase a use case in which DocDB will make a perfect fit.

In cache studio there are features, dialog boxes, that help map data from a global to class properties.
I have used %CacheSQLStorage quit a bit, or have in the past, to map globals to classes.

I haven't been able to find a similar feature in VisualStudio.
Do I need to upgrade to IRIS to be able to use VisualStudio to map global properties to classes?

Thanks for your time,
Richard

In ObjectScript you have a wide collection of functions that return some value
typically:

set variable = $somefunction(param1,param2, ...)

There is nothing special about that.
But there is a set of functions that I classify as LEFT SIDED
The specialty of them is that you can use them also on the left of the equal operator
as a target in the SET command:

set $somefunction(param1,param2, ...) = value

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.

A customer recently asked if IRIS supported OpenTelemetry as they where seeking to measure the time that IRIS implemented SOAP Services take to complete. The customer already has several other technologies that support OpenTelemetry for process tracing. At this time, InterSystems IRIS (IRIS) do not natively support OpenTelemetry.

Hi all,

We are delivering files to SFTP server using EnsLib.FTP.PassthroughOperation class and EnsLib.FTP.OutboundAdapter. But we are facing error below:

Hi Allen,

A partner have decided to change the algorithms that were used to connect on it's SFTP, but our version of libssh2 don't match with the list of it's HOSTKEYS algorithms.

If i update the library with the last version without to be sure that it includes the old algorithms, i risk to break the connection for other cases.

all suggestions are welcome. Thx

KR,

Amine

I'm trying to change the Stream property inside a DTL with a Source Class of Ens.StreamContainer. The code, below, will change it within the DTL testing tool, but running an actual message through the Production's Process doesn't change the Stream property. I can change other properties of Ens.StreamContainer by using the normal Set action and it is reflected when running it through the Process. For context, this uses a FTP service to grab a file. Any thoughts on why I can't just write modified stream data to the Stream property?

Recently, the question came up while discussing the access to the data stored in IRIS from different languages with my students if it was possible to initiate the connection and get data from Cloud solution (InterSystems IRIS CloudSQL) from Microsoft Excel, not the other way around. Considering the many varied ways one can get data in Excel (import data from external sources, connecting to databases using ODBC drivers, using power queries and web queries etc.) the obvious choice was to try ODBC driver. The only task left was to try to connect to the database in the cloud using the ODBC driver.
