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.

I am looking into creating a ZSTOP as you probably have seen from my previous posts, is there a way to capture the type of shutdown that occurred? So say if there was an unknown hardware failure (forced), vs a user shutdown? Mainly looking for user or system shutdown when we force another destination to become the primary in the mirror. So if a user shutdown the production to do.,... Task A, Task B etc..

Thanks

Scott

Introduction

This article is intended to be a simple tutorial on how to create ODBC connections and working with them, since I found starting with them a little bit confused, but I had amazing people to take my hand and walk me through it, and I think everyone deserves that kind of help too.
I'm going to divide each little part in sections, so feel free to jump to the one you feel the need to, although I recommend reading everything.

I'm trying to read the response to a long (indefinitely) running HTTP response with Transfer-Encoding: chunked. Ideally I'd be able to read the individual chunks from the response and do something with them as they arrive rather than needing to wait for the response to finish (because it never will) - ultimately I'm thinking to wrap these back up over a WebSocket connection which seems cleaner from an API perspective.

So far it looks like my options are:

Introduction

In some of the last few articles I've talked about types between IRIS and Python, and it is clear that it's not that easy to access objects from one side at another.

Fortunately, work has already been done to create SQLAlchemy-iris (follow the link to see it on Open Exchange), which makes everything much easier for Python to access IRIS' objects, and I'm going to show the starters for that.

We have messages that are in a queued state for various reasons and when we do a manual shutdown of the instance, they are moved to a Suspended state. I thought I saw in the documentation somewhere a setting to make sure these messages stay in a queued state and not suspend them. Can someone confirm and point me in the correct location for that documentation, as I am trying to ensure that if we do have to manually shutdown a instance, someone doesn't have to remember to go back in and check for suspended messages and resubmit them?

Thanks

iris-docker-multi-stage-script

A python script to keep your docker iris images in shape ;)

Witout changing your dockerfile or your code you can reduce the size of your image by 50% or more !

TL;DR

Name the builder image builder and the final image final and add this to end of your Dockerfile:

Modify your Dockerfile to use a multi-stage build:

ARG IMAGE=intersystemsdc/irishealth-community:latest
FROM $IMAGE as builder

Add this to end of your Dockerfile:

FROM $IMAGE as final

ADD --chown=${ISC_PACKAGE_MGRUSER}:${ISC_PACKAGE_IRISGROUP} https://github.com/grongierisc/iris-docker-multi-stage-script/releases/latest/download/copy-data.py /irisdev/app/copy-data.py

RUN --mount=type=bind,source=/,target=/builder/root,from=builder \
    cp -f /builder/root/usr/irissys/iris.cpf /usr/irissys/iris.cpf && \
    python3 /irisdev/app/copy-data.py -c /usr/irissys/iris.cpf -d /builder/root/

Boom! You're done!

Questions about using ZSTOP

I am working on setting up our Failover techniques as we move to a Mirror Environment with a Arbiter, 2 Failover Nodes, and a Async (DR) Node. There are some system commands that I would like to call when the Mirror moves, and I am working on a ZMIRROR routine for that, but I also wanted to create an additional step if we wanted to manually shutdown and for the Mirror to move. So I was looking at using ZSTOP to call a couple of different items while shutting down, while the documentation has an example a couple of questions come to mind about using ZSTOP.

Foreword

InterSystems IRIS versions 2022.2 and newer feature the ability to authenticate to a REST API using JSON web tokens (JWTs). This feature enhances security by limiting where and how often passwords transfer over the network in addition to setting an expiration time on access.

The goal of this article is to serve as a tutorial on how to implement a mock REST API using InterSystems IRIS and lock access to it behind JWTs.

Reference for the JSON Web Classes

Foreword

InterSystems IRIS versions 2022.2 and newer feature a redesigned functionality for JSON web tokens (JWTs). Once housed under the %OAuth2 class package, the JWT class, along with other JSON web classes (JWCs), now live under %Net.JSON. This migration occured in order to modularize the JWCs. Before, they were closely intertwined with the implementation for the OAuth 2.0 framework. Now, they can be maintained and used separately from OAuth2.

_spec for swagger-ui from spec class

Surely you wanted to use the OpenAPI Specification (OAS) JSON you used for your spec class on the iris-web-swagger-ui iris package. The generated OAS from the ##class(%REST.API).GetWebRESTApplication(...) method is very crude, with no description on the parameters or the expected response structure.

So after creating your REST application from an OAS you should have:

InterSystems announces its third developer preview, as part of the developer preview program for the 2023.1 release. Many updates and enhancements have been added in 2023.1 and there are also brand-new capabilities, such as production-ready support for Columnar Storage, ability to use Bulk FHIR, and support to MacOS 13 Ventura. Some of these features or improvements may not be available in this current developer preview.

I asked the question in email and get answers from those colleagus.

Question:

I failed to change time zone on latest iris container(Ubuntu), because:

  • I am irisowner, no root password

  • There is no sudo command

I used to use below Dockfile setting to change time zone while creating a new docker image. However, those commands doesn’t work from non-root user.

Hi Friends ,

We have requirement to load data into chache tables from external database (ref data). This process will take 1 min to complete all data load.

Currently I have created Business Service to trigger Business Operation with out bound db adapter to load data into cache tables.

process will be trigger when i restarted business service.

But requirement is , this business service should be triggered from outside ensemble environment i.e , this should expose as REST endpoint and share with the external team.

Quick sample database tutorial

Introduction

This is a simple tutorial on the quickest way I found to create a sample database for any purposes such as testing, making samples for tutorials, etc.

Creating a namespace

  1. Open the terminal
  2. Write the command "D $SYSTEM.SQL.Shell()"
  3. Write "CREATE DATABASE " and the name you want for your namespace.

Now you have a new namespace in a faster way than creating it from the Management Portal - which of course offers way more configuration options.

I've been working for some days in the connectivity between NodeJS client applications and IRIS as server using web sockets.

You can get all the information in relation to the web socket connections using IRIS as a client or as a server from this URL: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls...

Code Golf: Isogram

It's time for a Code Golf round!

Isogram

A word or phrase that has no repeating letters, consecutive or non-consecutive.


Implement a method that checks if the received string is an isogram or not.
Assume the empty string is an isogram.
Ignore the letter case.

Allowed inputs: A-Z, a-z.

As usual, the shortest solution wins!

Hello everyone,

As someone who is new to the world of InterSystems technology, I have been looking for the best resources to learn more about it.

I have heard great things about InterSystems technology, particularly its speed and scalability, and I want to make sure I have a solid understanding of it before diving in further. From what I understand, the official InterSystems courses cover a wide range of topics and are taught by experts in the field.
