An interesting pattern around unique indices came up recently (in internal discussion re: isc.rest) and I'd like to highlight it for the community.

As a motivating use case: suppose you have a class representing a tree, where each node also has a name, and we want nodes to be unique by name and parent node. We want each root node to have a unique name too. A natural implementation would be:

Showing dates in missing periods

When we collect temporary data (the number of purchases in the store, the number of comments on the post), it may happen that there is no data for a certain period of time. In this case, this time period (hour, day, month) is not represented in the database, that is, there is not a single row for this period. In other words, there are no rows in the database for this period.

I have successfully created REST service classes on my local IRIS server following this book: Using the /api/mgmnt/ Service | Creating REST Services | InterSystems IRIS Data Platform 2021.2

I am now 1) trying to edit impl.cls in VS Code and 2) export it to my local repo so I can push to the remote repo.

When I click on my project in VS Code and 'Add to project' and choose the new package, spec.cls and impl.cls, I get the following error:

Hi:

Had an issue after upgrading to 2021.1 where search bar for interoability will bring up "INVALID ACTION".

On upgrading to 2022.1 this still occurs.

It did not occur on another environement that was upgraded from 2017.2 straight to 2022.1

Is there any solution? Loads up SYS in url rather than customnamespacename

Issue is the url for instance brings through ip/csp/sys/EnsPortal.DTLEditor.zen?$NAMESPACE=X

I would say it is a post of pain after years of using InterrSystems IRIS Docker images in many projects.

And I hope InterSystems will hear me and do something with it.

We have a lot of issues with Docker images, but I see no progress in solving them.

  • containers.intersystems.com - any new releases substitute previous versions, makes build useless
    • ARM64 images have separate names, and it makes a pain to use them
  • flags in iris-main, appears and disappears from version to version, which may fail the start the container
  • healthcheck does not work as expected

Process XML document

Hi all,

I am looking at a task which involves processing an XML file. Picking the file up from a folder (c:\test.xml) reading the data out of the XML and archiving the xml after it has been processed.

I was wondering what the best way of doing this would be?

I have got as far as creating a service in Ensemble. The Service I have created uses the class name EnsLib.XML.Object.Service.FileService.

Any advice or tutorials/guides would be much appreciated.

Many Thanks

Hello,

I found another question on how to change the language for Studio (but it would've been nice to have my actual language used - Ukrainian, since it's available, or was available). Still, I can't seem to figure out how to get rid of gibberish in the menu without changing the Windows settings:

Good morning. Perhaps someone can tell me if this IRIS health communit version (IRISHealth_Community-2022.1.0.209.0-lnxubuntu2004x64) is supposed

to work in an Ubuntu 20.04 LTS installation in an Oracle Virtual Box .

I am trying to install different versions on Ubuntu . I tried with the 18 version. No luck. Than I've tried with the 20.04 version. No luck either.

The error I am having now is below

Default Database Resource

Can I please check if anyone know why the data base resource is created differently when creating a namespace after specifically selecting it to use the default resource %DB_%DEFAULT?

I created a namespace and when creating the DB I selected the option to use the default resource

When the namespace creation was complete , database is using a new resource instead of the default.
