Is there a way to force a failover from the primary mirror member to the backup member without forcing down the primary (which happens with ##class(SYS.Mirror).BecomePrimary())? What I'm trying to simulate is a network isolated condition on the primary.

InterSystems has corrected two defects that affect online backup of very large databases. Backups taken via external methods, such as snapshots or direct file copies, are not affected. These defects exist in all released versions of all InterSystems products.

The first defect only affects databases with more than 2³¹ blocks. It results in a degraded database after restoring from an online backup. For example, databases that have a block size of 8 KB (the default) are only affected if they are larger than 16 TB. The correction for this defect is identified as RJF437.

Note (October 2022): yape has been deprecated and replaced by YASPE, there is no more development on yape.

Note (June 2019): A lot has changed, for the latest details go here

Note (Sept 2018): There have been big changes since this post first appeared, I suggest using the Docker Container version, the project and details for running as a container are still in the same place  published on GitHub so you can download, run - and modify if you need to.

Hi!

Is there a method in a persistent class that can return the current number of records/persistent objects in it?

Preview releases are now available for the 2020.2 version of InterSystems IRIS, IRIS for Health, and IRIS Studio!

The build number for these releases is 2020.2.0.196.0.

Container images, components, and evaluation license keys are available via the WRC's preview download site.

Community Edition containers can also be pulled from the Docker store using the following commands:

• docker pull store/intersystems/iris-community:2020.2.0.196.0
• docker pull store/intersystems/irishealth-community:2020.2.0.196.0

InterSystems IRIS Data Platform 2020.2 adds support for TLS 1.

I am trying to create REST API following these instructions:  https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=GREST_apimgmnt

However it does not work.

I tried downloaded the v2.0 schema.json of the OpenAPI specification and pasted it on Postman with the parameters as speicifed, but I get this error message back:

{
    "msg": "ERROR #8738: Correct OpenAPI 2.0 version was not specified: . <$.swagger>\r\n  > ERROR #5490: Error running generator for method '%OnCompile:TasksRestApp.spec' \r\nERROR: %REST.Spec.cls(%OnCompile) of generated code compiling subclass 'TasksRestApp.

Hi Community,

The new video from Global Summit 2019 is already on InterSystems Developers YouTube:

⏯ Leveraging Containers for DevOps

Hi Community,

We're pleased to invite you to join the upcoming InterSystems IRIS 2020.1 Tech Talk: Integrated Development Environments on May 19 at 10:00 AM EDT!

In this edition of InterSystems IRIS2020.1 Tech Talks, we put the spotlight on Integrated Development Environments (IDEs). We'll talk about InterSystems latest initiative with the open source ObjectScript extension to Visual Studio Code, discussing what workflows are particularly suited to this IDE, how development, support, and enhancement requests will work in an open source ecosystem, and more.

Hi Community!

We are glad to invite all the developers to the upcoming  InterSystems IRIS Native API Contest Kick-Off Webinar! The topic of this webinar is dedicated to the 3rd IRIS Programming Contest.

Date & Time: Monday, May 18 — 9:00 AM EDT

Speakers:  
@Bob Kuszewski, InterSystems Product Manager
@Evgeny Shvarov, InterSystems Developer Ecosystem Manager

What awaits you? Please check the agenda below:

Previously I showed you how to run pButtons to start collecting performance metrics that we are looking at in this series of posts.

• Part 1 - Getting started on the Journey, collecting metrics
• Part 2 - Looking at the metrics we collected

##Update: May 2020.

Since this post was written several years ago, we have moved from Caché to IRIS. See the comments for an updated link to the documentation for pButtons (Caché) and SystemPerformance (IRIS). Also, a note on how to update your systems to the latest versions of the performance tools.

Hi folks!

When I start IRIS in docker every time I do the following:

$ docker-compose up -d --build

$ docker-compose exec iris iris session iris

USER>zn "NAMESPACEINEED"

Is it possible to have an open terminal command connect to a particular namespace?

Hi Developers!

As discussed in previous parts of Package Manager stories to turn your IRIS application into a deployable package you just need to introduce the module.xml file into the root folder of the repository and describe all the resources.

I’m pleased to introduce you to a new project template on Open Exchange which contains examples of how to make different types of resources of your InterSystems IRIS application a part of the ObjectScript package and so make the deployable ObjectSctipt package.

Let's see how you can describe your application resources using this template project as an example.

See the details below.

I've created a new repository that I will use for providing examples of various scenarios and use cases for QEWD

https://github.com/robtweed/qewd-microservices-examples

Initially it contains a example of a scenario I'm often asked about: a set of REST APIs, with JWT support, implemented as a set of QEWD MicroServices, each of which uses Cache or IRIS running on a Windows system.

What I've provided is a detailed, step-by-step guide (with detailed explanations) of how to set up such a system.

Allow limited durability for demo and development IRIS-Docker-micro-Durability During development of a container based demo I found the need to access a fresh docker
an instance of IRIS image (e.g intersystems/iris-community:2020.2.0.199.0) over and over.
To bypass loading my code repeatedly, I developed this workaround.

Docker support

The principle of a persistent IRIS database outside the container is unchanged.
But now the whole setup is moved into Dockerfile and docker-compose.yml

Prerequisites

Make sure you have git and Docker desktop installed.

Using the IRIS native API for Node.JS was the opportunity to present
a MicroService operating in a Docker container.
A demo video is now also available to watch the demo in operation.

Instead of a utility you call directly on your IRIS host you now send a work-packages
to the MicroService as would typically do with System Interoperability (aka.ENSEMBLE):
of course, you have the option of more than one WebSocket Server.
Once the WebSocket Client Service has done its job you get back the result from it.

As promised, here is Part 2 of our interview with Russ Leftwich! In this half, Adam Coppola talks with Russ about some of the InterSystems technologies that play a part in the concepts from Part 1, as well as some specific discussions about modern FHIR applications. After the interview with Russ, we were also joined by Jenny Ames to talk about the upcoming FHIR Dev Days. Check it out, and make sure to go subscribe to Data Points!

Hi Community!

We're pleased to invite you to the Online Meetup with the Winners of the 2nd IRIS Programming Contest! It's a virtual Meetup with some of the winners of the past InterSystems IRIS Online Programming Contest. 

Date & Time: Friday, May 8, 2020 – 11:00 EDT

What awaits you at this virtual Meetup? 

• Our winners' bios.
• Short demos on their applications.
• A short interview with all the winners about the past contest. Plans for the next contests.

Introduction

In the first article in this series, we’ll take a look at the entity–attribute–value (EAV) model in relational databases to see how it’s used and what it’s good for. Then we'll compare the EAV model concepts to globals.

Sometimes you have objects with an unknown number of fields, or perhaps hierarchically nested fields, for which, as a rule, you need to search.

Take, for example, an online store with diverse groups of products. Each product group has its own unique set of properties and has common properties as well.

After I loaded the intersystems/iam:0.34-1-1 image in local, I am trying to do the next step of configuration.

2) Configure your InterSystems IRIS instance

  2a) Enable the /api/IAM web application
  2b) Enable the IAM user
  2c) Change the password for the IAM user

Do we need to change these settings in iris.cpf file? any inputs where we have to configure? I have IRIS 2019.1.1 installed in my machine.

Thanks,

Nag.

Hi again!

I logged into the demo IRIS again, and for some reason, today, I had an "Classpath is incomplete" warning message. The classpath is defined under quickstarts-multimodel-java.  Here is the contents of the file :

<?xml version="1.0" encoding="UTF-8"?>

<classpath>

    <classpathentry kind="src" path="src"/>

    <classpathentry kind="lib" path="lib/intersystems-jdbc-3.0.0.jar"/>

    <classpathentry kind="lib" path="lib/intersystems-xep-3.0.0.jar"/>

    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.

See Part 1 here.

Part 2: Index Handling

Now you have a good idea of what kind of indices you need for your class and how to define them. Next, how do you handle them?

Query Plan

(REMEMBER: Like any modifications to a class, adding indices in a live system has its risks – if users are accessing or updating data while an index is populated, they may encounter empty or incorrect query results, or even corrupt the indices that are being built.

I have just started to experiment with Using IRIS in Docker.

My first objective was to be able to enable global persistence within a Docker container. Using the following command I have managed to achieve this:

docker run --detach --publish 52773:52773 --volume /data/dur:/dur --env ISC_DATA_DIRECTORY=/dur/iconfig --name iris21 store/intersystems/iris-community:2020.1.0.199.0

Within this container, I have created a simple global:

for i=1:1:10 set ^tmp(i)=""

I then stopped and removed the container. On reloading and restarting the container the global has persisted.

Hi Developers!

The second InterSystems Online Programming Contest is over. Thank you all for participating in our IRIS Competition!

As a result - 7 great apps! And now it's time to announce the winners! 

objectscript-json-patch

An implementation of JSON-Patch in ObjectScript.

Why you should use JSON-Patch

JSON-Patch (RFC6902) is a standard format that allows you to update a JSON document by sending the changes rather than the whole document. JSON Patch plays well with the HTTP PATCH verb (method) and REST style programming.

Install

With zpm :

USER>zpm
zpm:USER>install objectscript-json-patch

How-To use it

Use it with this call :

Do ##class(Grongier.JSON.Utils).Patch(tDoc,tPatch)

Where :

• tDoc is a %DynamicObject (JSON)
• tPatch is a %DynamicArray of the patches (the JSON Patch).

Hi Developers!

We are going to establish a series of InterSystems IRIS Online Programming contests this year.

In March we started with ObjectScript CLI and here is the schedule of topics for the next few months:

• April - InterSystems IRIS with REST API
• May - InterSystems IRIS Native API application: use Python, JS, .NET, Java native APIs in your application to use IRIS
• June-July - InterSystems IRIS AI/ML solutions. IntegratedML as a bonus
• August - InterSystems IRIS for Health FHIR application
• September - InterSystems IRIS Full-stack application: IRIS as a server and UI on any framework and any form: and web, desktop, mobile UI
• October - Interoperability solutions for InterSystems IRIS and InterSystems IRIS for Health
• November - Analytics Solution using InterSystems IRIS
• December - Multi-model solution using InterSystems IRIS

All applications should be runnable with InterSystems IRIS in a docker container.

Hi Developers,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ Developing Progressive Web Apps

I am trying to install IAM in my local and I downloaded IAM-0.34-1-1.tar.gz and extracted. I went to the location where iam_image.tar is available and run below command in the command prompt. 

C:\ESB\HC\IAM-0.34-1-1.tar\IAM-0.34-1-1\IAM>docker load -i iam_image.tar
unsupported os linux

Getting unsupported os Linux issue. Kindly let me know if anyone had this issue. Thanks!

Purpose

Over the Easter Weekend I touched on some deep learning classifier for Covid-19 Lungs.  The demo result seems fine, seemingly matching some academic research publications around that time on this topic. But is it really "fine "? 

Recently I happened to listen to an online lunch webinar on "Explainability  in Machine Learning", and Don talked about this classification result at the end of his talk:

The above figure is also presented in this research paper: “Why Should I Trust You?

I'm wondering if anybody has done an implementation of the https://www.shibboleth.net/products/service-provider/ interface in Caché / IRIS to have a application running in Caché / IRIS be acception the shibboleth tokens and data as  usage credentials.

Hi Developers!
