REST API with Swagger in InterSystems IRIS

Hello

The HTTP protocol allows you to obtain resources, such as HTML documents. It is the basis of any data exchange on the Web and a client-server protocol, meaning that requests are initiated by the recipient, usually a Web browser.

REST APIs take advantage of this protocol to exchange messages between client and server. This makes REST APIs fast, lightweight, and flexible. REST APIs use the HTTP verbs GET, POST, PUT, DELETE, and others to indicate the actions they want to perform.

It's been a while since the new UI for Productions and DTL was published as a preview and I would like to know your opinions about it.

WARNING: This is a personal opinion, totally personal and not related with InterSystems Corporation.

I'm going to start with the Interoperabilty screen:

Production screen:

The style is sober and without frills, following the line of cloud services design, I like it.

Hello,

While doing research on the upgrade to InterSystems IRIS 2024.1.2 version, I was wondering if it would be possible to rollback the installation and return to the previous version in case something went wrong ?

I didn't see anything talking about this in the documentation and when I tried to re-install an older kit over an upgraded instance, I couldn't use it.

Thank you in advance for your reponse

I am just writing something to share what I encountered last night, which is the IRIS 2024.3 does not comes with Python by default any more!!!

Which means that I need to install it by myself!!😅 The pros is, I can select my python version😁🤭💃 The trouble is.... at the first place.... I don't know what I should do😥. By going through the community (I am much more prefer than the official document, sorry InterSystems document team😓 ), I found the following piece

Are you familiar with SQL databases, but not familiar with IRIS? Then read on...

About a year ago I joined InterSystems, and that is how IRIS got on my radar. I've been using databases for over 40 years—much of that time for database vendors—and assumed IRIS would be largely the same as the other databases I knew. However I was surprised to find that IRIS is in several ways quite unlike other databases, often much better. With this, my first article in the Dev Community, I'll give a high-level overview of IRIS for people that are already familiar with the other databases such as Oracle, SQL Server, Snowflake, PostgeSQL, etc. I hope I can make things clearer and simpler for you and save you some time getting started.

Are there any objectscript functions (not wizards) to export and then import table data (including RowID)?

It doesn't matter what format the exported file is.

The import and export process should preserve all relationships, foreign keys, etc. I need to be able to export and import multiple tables at the same time.

I need this to implement the ability to export multiple tables from one instance and load them into another.

Introduction

MonLBL is a tool for analyzing the performance of ObjectScript code execution line by line. codemonitor.MonLBL is a wrapper based on the %Monitor.System.LineByLine package from InterSystems IRIS, designed to collect precise metrics on the execution of routines, classes, or CSP pages.

The wrapper and all examples presented in this article are available in the following GitHub repository: iris-monlbl-example

Hi Community,

I have a CSP page I am developing with the intent of pulling files from an SFTP site and placing them in a folder on the local network.

I am having an issue where the CSP page is catching a JS error. The error in the browser is - A JavaScript exception was caught during execution of HyperEvent: SyntaxError: Unexpected identifier 'downloading'. (However, the unexpected identifier changes after refreshing page, or after removing the Write statement with the work 'downloading' in it.)

I think I have narrowed it down to a piece of the Javascript code -

Migrating InterSystems IRIS and InterSystems IRIS for Health from on-premises to the cloud offers many advantages for Application Providers and Solution Providers. These advantages include simplified operations, access to flexible resources, and enhanced resilience. Companies no longer need to worry about the physical constraints and expenses associated with maintaining on-prem infrastructure, such as power and space requirements and expensive computer hardware.

One of the most compelling benefits is the ability to accelerate speed to market. By removing the burden of infrastructure maintenance, cloud environments enable faster development and deployment cycles, allowing businesses to respond quickly to market demands and opportunities. Operational costs are also lowered, because companies can scale resources up or down based on actual needs, leading to more efficient use of capital. Moreover, migrating to the cloud can contribute to a reduced carbon footprint by optimizing energy usage through shared cloud infrastructure.

Transitioning to the cloud may involve significant changes. Companies may benefit from a more operational focus, managing and optimizing cloud resources continuously. This shift may require changes to business models, reconsideration of margins, and strategies for scaling operations up or out. While requiring more investment, embracing these changes can lead to improved agility and competitive advantage in the marketplace.

Sometimes customers need a small IRIS instance to do something in the cloud and shut it down, or they need hundreds of containers (i.e. one per end user or one per interface) with small workloads. This exercise came about to see how small an IRIS instance could be. For this exercise we focused on what is the smallest amount of memory we can configure for an IRIS instance. Do you know all the parameters that affect the memory allocated by IRIS ?

Iterate over array of namespaces

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.

Hi Team, we are going to deliver a speech on a developer forum where most developers hv not used our tech before but using other database and integration technologies , Pls give us some key points on why they should adopt us and the benefits you can get, especially if you change your tech stack from others to IRIS. Thanks a lot!

Hi there,

I'm hoping that someone may be able to point me in the right direction to get started with working with files in Intersystems. I am currently trying to build an interface that will consume a text file containing a list of IDs (one per line) and then write those IDs to an external database. I am comfortable working with the database end but have not worked with files/Stream containers etc yet.

I want to integrate IRIS with Keycloak OAuth2 provider to use delegated authentication everywhere and to secure everything - sys*/Portal applications, REST services, FHIR server and so on. If an unathenticated user tries to access any IRIS URL - he or she should be redirected to Keycloak. After the user has successfully authenticated, i would like to access his requistes (username, email, roles, scopes) extracted from the JWT token, programmatically. What should be done to achieve that?
