Hello 

Is there an example how to configure the webgateway on linux with kerberos in the dokumentation I found something but not realy in detail so far I understand I need two priniples one service prinple account with for example iris/at-mie-centos_iris.balmie.local@BALMIE.LOCAL-> there is my first problem with the dokumendation the @BALMIE.LOCAL is not dokumented but if you create a keytabfile with ktpass you can't create this without domain. For the secound user principle I am totaly lost how it should work must be both account in the keytabfile? and if so how can I connect this princple t

Hello developers!

Share the best practices: 1) saving frequently used code sections, 2) quickly finding it, and 3) quickly including it into the current program? There was a thought for 1,2 to use DC(this resource), but the search is not always convenient not only for me

The idea on the surface is to use the git repos wiki. Are there any other best practices?

There is a project github awesome. Maybe we should include the awesome-objectscript sections in it? And in the future for vscode to develop a plugin for awesome-objectscript ?

No reason apparently,

no details on audits, no traffic for that, no process to justify this, some ideas ?

Hi everyone, 

I'm trying to build my project on a Linux machine using Docker.

In my development environment, I use Windows 10 Pro with Docker Desktop version 2.3.0.5. Everything works fine, and the docker-compose build runs flawlessly.

But, when I tried to run the same project in a Linux. 
Ubuntu 18.04.5 LTS (GNU/Linux 5.4.0-1025-azure x86_64), docker --version
Docker version 19.03.6, build 369ce74a3c

I'm getting the following error: 
ERROR: Service 'iris' failed to build: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"/irissession.sh\": permissi

Hi Community!

In the WRC, we often see customers who have encountered a problem viewing their SOAP Catalog pages in a browser. This article will explain why the error is being encountered, as well as suggest a fix. This explanation is focused on the symptoms seen in InterSystems IRIS, but similar behavior can be seen in more recent versions of Caché.

The Problem:

You are trying to create new SOAP Web Services in InterSystems IRIS. When you go to view the SOAP Catalog for what you have created so far you encounter the following error in your browser:

On older CSP Gateway and Caché instances, this might

Dear Folks,

I am looking for a native approach to call a ClassMethod of an instance from another instance (Instances are running in different servers).  I can still do this via API over Http or any other communication method but I believe it would be better if I communicate via IRIS native methods(If exists).

Thanks

Hello Developer Community!

I’m pleased to announce the 0.9 release of the ObjectScript extension for Visual Studio Code. Earlier this year I announced that InterSystems would be joining the community in evolving this already popular tool. Since then, we have been hard at work solidifying the code base and building a slew of new features.

Before I get into the details, I’d like to take a moment to thank @Dmitry Maslennikov, @John Murray and the VS Code team at InterSystems for wholeheartedly embracing this new way of collaborating in the open, and working together to build a product that is t

Hi,

Does anyone have a simple code snippet to encode and upload a raw text to Azure Blob?

InterSystems has corrected a defect that can cause a build-up of orphaned processes consuming system resources. In extreme cases, this can cause a system to become unresponsive.

This defect affects the following versions:

• Caché and Ensemble 2018.1.4
• InterSystems IRIS and InterSystems IRIS for Health 2019.4, 2020.1, and 2020.2
• HealthShare Health Connect (HSAP) 15.032 built on Ensemble 2018.1.4
• HealthShare Health Connect 2020.1

No other InterSystems product versions are affected by this issue.  Specifically, earlier versions of Caché and Ensemble, Health Connect 2019.1 and 2019.1.1 and

I am currently working with docker for the first time the last month. I created a project with these 2 images:

• https://hub.docker.com/_/intersystems-iris-data-platform (for backend)
• https://hub.docker.com/_/nginx (for frontend)

My docker-compose.yml looks like this:

    version: '2'
    services:
        frontend:
            container_name: frontend
            build: 
                context: ./container/frontend
                dockerfile: Dockerfile.yaml
            ports:
                - "8080:80"
            
        backend:
            container_name: iris

Purpose:

We touched on some quick demos of  deep learning and machine learning over the past few months, including a simple Covid-19 X-Ray image classifier and a Covid-19  lab result classifier for possible ICU admissions.  We also touched on an IntegratedML demo implementation of the ICU classifier.  While the "data science" hiking still goes on, it might also be a good time to try some AI service deployment from the "data engineering" perspective - could we wrap up everything we touched on so far i

It's well-known among Studio users that besides few predefined code fragments (for ObjectScript, Basic, MV Basic) it's possible to add user-defined code fragments. I found it rather convenient to use them as patterns that help to follow some conventions (internal standards) of writing, say, methods descriptions.

But I didn't find a way how to share these patterns, except dumb copy-pasting. Did somebody succeed with this task? Any help would be appreciated.

The use of Source Code Control systems in development is important. And there are a few systems known in the world, like GIT, SVN (Subversion), Perforce, Mercurial. Where the most popular nowadays is the git. Using it is very useful in many cases, but mostly it depends on the code as text, which can be compared between commits, branches, or versions of releases and so on. 

And InterSystems ObjectScript is not an exception, for many years it was possible to use SourceControl class in Studio, which helps to work with any Source Code Control System, and some companies already used it for many ye

A Webinar was held today for our Czech and Slovak partners and end users. This webinar was an online version of what we originally planned to present earlier this year in Fabrika hotel, Humpolec as a workshop. Due to the current epidemiologic situation a decision was made to move the workshop into the virtual space.

Error management on InterSystems languages has been evolving along time. Next, we will show the different implementations and why you should use the TRY/THROW/CATCH mechanism.

You can read official error recommendations here.

InterSystems will not mark as obsoletes the non-recommended error management methods to allow giving support to legacy applications. We recommend using tools like objectscriptQuality to detect that legacy unrecommended usage along with many other possible issues and bugs.

$ZERROR is the older error management mechanism, supporting different implementations fro

I was able to define ECP connection in Installer class that I run when I build docker image for my Docker IRIS application. Now I start to use Amazon ECS and Autoscaling. When a new instance is created and it runs the IRIS container, I want it to "register" as an Application server on the remote database server. What code can I execute to add an ip address as an Application Server?

Just like the title, I want to do code version control. I don't want to change CLS at will, but I don't want to use MakeClassDeployed, I just want to set the cls or mac to read-only and uneditable state。Does CLASS have such property?

I need to consume the content of ^SPOOL output over SQL.
^%SPOOL utilities don't look so promising

I am trying to compare times on an IRIS instance. The times are in the W3C format (https://www.w3.org/TR/NOTE-datetime). Are there any in-built helper functions in IRIS to support time comparisons in this format or will I need to parse it using functions such as $zdateh and $ztimeh to do the comparisons?

Hello,

Recently I tried to connect to JDBC on IRIS 2020.3+ and I came across the following error:

 SQL Error [461] [08S01]: [InterSystems IRIS JDBC] Communication link failure: Communication error: Server closed communication device

This error implies that the port is not open.
