October 26, 2021 – Alert: Missing Locks after ECP Database Server Restart or Failover

InterSystems has corrected a defect that can violate application locking guarantees in a distributed cache cluster (ECP configuration), which can lead to application integrity issues. This defect affects:

• All major releases and maintenance versions of InterSystems IRIS and InterSystems IRIS for Health, starting with 2020.1.

Hey community, how are you doing?

How do you exercise your creativity? How do you test new ideas?

Over the years I have always thought about creating new things, modifying existing ones, experimenting, testing, breaking (it always happens), building again, starting over.

The contests promoted by InterSystems are an excellent source of motivation, obviously, the prizes bring a lot of attention and this you cannot deny. But not just prizes/rewards, they also give us a creative challenge, an opportunity to create, reimagine, test, experiment.

Hey Community,

We want to hear from you! Give us your feedback on the past InterSystems Interoperability programming contest! Please answer some questions to help us improve our contests.

InterSystems Global Summit (or Virtual Summit this year) is traditionally a time of big announcements, and I'm sure our friends from InterSystems have quite a lot of new and exciting things to share with us this year. Here at Banksia Global, we have a big announcement for you as well. Please meet our new website built to make IRIS-based software distribution a breeze: ZpmHub.com!

Quite a complex scenario we are trying to solve but should be able to understand.

We're developing a task executer that runs on a server with a certain timezone.

The tasks run every day at a defined time, but in different timezones.

We're saving in database at what time we want to execute the task, and in what timezone (don't go to the save in UTC pitfall, as with DST it will be at different times)

What I want to do if when opening a task from the database, convert 02:00 Europe/Madrid, either to UTC or to local (server) time.

I've found the class HS.Timezone.Server.

Hey Developers,

It's time to announce the winners of the InterSystems Interoperability contest!

Thank you all for participating in our coding competition! And the winners are...

A storm of applause goes to these developers and their applications:

Hello everyone,

I would like to know what is the best terminal emulator in your opinion? I am using MobaXTerm, but  i'm having some difficulties with the charset configuration. 

Best Regards.

Hello everyone!

Me and @Henrique.GonçalvesDias proposed a new way to visualize messages in IRIS Interoperability in a recent update of MessageViewer. In such an update, we tried to give users a visualization based on a UML sequence diagram. You could get more information on the previous article.

In order to get all the hard geometry calculations needed to draw such a diagram done, we used the amazing mermaid JS open source library. And what I’d like to share with you in this article, is how to use this library.

We'll be showcasing some advanced features of Deltanji and Serenji in VS Code with time for a discussion - so feel free to bring along any problems you need help solving or share your feedback on our tools. We'd love to hear your thoughts. 

You can find out more on Eventbrite. 

Everyone is welcome. If you're interested in our tools this is a great chance to hear what others have to say, as well as asking your own questions.

We hope to see you on November 3rd! 

Interoperability Read Only access

In companies, most of the time, we have test, stage and production environments.

It is very common that we, the developers, do not have the right to modify or touch the production directly because all the modifications must be traced in a versioning tool and tested before a production release.

However, a read access to the production (especially to the traces) can allow us to better understand a possible bug.

That's why I propose this ZPM module that creates a new role in IRIS that allows access to the productions and this only in read-only with access to the visual traces.

In the last years the data architecture and platforms focused into Big Data repositories and how toprocess it to deliver business value. From this effort many technologies were created to process tera and petabytes of data, see:

The fundamental piece to the Big Data technologies is HDFS (Hadoop Distributed File System). It is a distributed file system to store tera or petabytes of data into arrays of storages, memory and CPU working together.

Hi Community,

The InterSystems IRIS has a good connector to do Hadoop using Spark. But the market offers other excellent alternative to Big Data Hadoop access, the Apache Hive. See the differences:

Source: https://dzone.com/articles/comparing-apache-hive-vs-spark

I created a PEX interoperability service to allows you use Apache Hive inside your InterSystems IRIS apps. To try it follow these steps:

1. Do a git clone to the iris-hive-adapter project:

$ git clone https://github.com/yurimarx/iris-hive-adapter.git

2. Open the terminal in this directory and run:

$ docker-compose build

The InterSystems Certification Team is building an InterSystems IRIS Integration Specialist certification exam and is looking for Subject Matter Experts (SMEs) from our community to help write questions. You, as a valued InterSystems community member, know the challenges of working with our technology and what it takes to be successful at your job. In exchange for your assistance you will be compensated up to $500 per work assignment.

I work as an Integration Engineer for United States Department of Veterans Affairs (VA). I work on a Health Connect production which processes many RecordMap files. I do not fully understand RecordMaps and I wanted to develop an application for the Interoperability contest where I could learn more about working with RecordMaps. I browsed InterSystems documentation for inspiration on how to start. I was happy to find CSV Record Wizard. I had created a CSV file for my Analytics contest entry. I wanted to use it to test the CSV Record Wizard. It was not obvious how to use it.

Hey Developers,

Hello everybody,

I am trying to export a class to xml and remove the tag "xmlns" from mother class. These are my classes to create the XML.

Class Class.Test Extends (%RegisteredObject, %XML.Adaptor)
{ 

Parameter NAMESPACE = "http://mynamespace.com/test"; 
Property Person As Class.Person; Property Address As Class.Address; 

}

Class Class.Person Extends (%RegisteredObject, %XML.Adaptor)
{ 

Parameter NAMESPACE = "http://mynamespace.com/test"; 
Property name As %String; Property age As %String; 

}

Class Class.Address Extends (%RegisteredObject, %XML.

The latest release of Serenji focuses on the debug experience. Not only can you now debug on the spot, no matter where you are or what you're doing, but we've also added some smaller features that will make debugging more straightforward. 

• Run and Debug CodeLenses - clickable links above each class method, procedure, subroutine or extrinsic function.
• Intuitive prompting for entrypoints and arguments - when debugging a class method, produce, subroutine or extrinsic function. 
• Shaded read-only background - to clearly differentiate between documents which are editable and those that are read-only. 
• Program output in debug console - output is shown in the debug console. 
• Serenji commands on Server Manager's namespace trees - allowing you to launch Serenji through Server Manager. 

Find out more in our release notes here.

Hi everyone!

I am trying to localize text in an XData block using the $$$Text macro. A snippet of code is included below. Is there an easy way to localize the text included in an XData block? So far, using the $$$Text macro is not working; when I export the %MessageDictionary, the text to be localized isn't included in the export.

XData LocalizedEmail [ MimeType = text/html ]
{
<body>

Text to be translated into another language

}

Thank you in advance!

Hey Developers!

We're pleased to announce the next competition of creating open-source solutions using InterSystems IRIS or IRIS for Health! Please join:

⚡️ InterSystems Interoperability Contest ⚡️

Duration: November 2-22, 2020

I have written below method inbound adapter myAdapter Extends Ens.InboundAdapter [ ProcedureBlock ] returns -400

If i have written in any other Extends %Persistent  cls , always returning -30 which means Table not found

ClassMethod FetchMsgCount() As %Integer
{
    set msgCount=-1
&sql(SELECT count(ID) INTO :msgCount FROM Ens.MessageHeader)
If SQLCODE=0 Quit msgCount
Quit SQLCODE
}

Could you please some one tell me where should write this class method? What I am doing wrong?

Thanks

I have been reviewing the details on the CPF Merge functionality offered in IRIS:

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl…

I love the frequent mentions of versioning the CPF merge files in Source control.

Hi Community,

New video is already on InterSystems Developers YouTube:

⏯ Fast & Efficient Provisioning & Testing with InterSystems Cloud Manager

We have in our company a task that use many times a job command, and we receive this message "<LICENSE ALLOCATION EXCEEDED>". I thought that a new license is consumed only when we acess with another IP address the database.

Can anyone explain this to me?

Have you ever seen those vaccum compressed towels, that look like a pill and after you add water became a towel?

That's our challenge for today. As usual shortest solution wins.

Task

You will receive an integer number and you will return a new number where each digit is repeated a number of times equals to its value.

Input:

42

Output:

444422

Note:

• Input is only made of digits [0-9]
• Zero returns an empty string
• Use this code to check the result length
• You also can use this test case here

Hi,

I am using container to run IRIS. In my file service I defined following path:

How can I copy file to container location?

Thanks

Introduction
Several resources tell us how to run IRIS in a Kubernetes cluster, such as Deploying an InterSystems IRIS Solution on EKS using GitHub Actions and Deploying InterSystems IRIS solution on GKE Using GitHub Actions. These methods work but they require that you create Kubernetes manifests and Helm charts, which might be rather time-consuming.
To simplify IRIS deployment, InterSystems developed an amazing tool called InterSystems Kubernetes Operator (IKO). A number of official resources explain IKO usage in details, such as  New Video: Intersystems IRIS Kubernetes Operator and InterSystems Kubernetes Operator.
