Hi fellow developers!

Curious if you guys use CreatedAt and LastUpdated properties in your classes?

Created to stamp when the record was created and LastUpdated when it was last updated. Where it can be useful - almost everywhere )) I find it convenient in records sorting (e.g. by creation or last update), in sync (with other systems), and so on, for better analytics.

Do you use it all the time for all the classes?

If don't, why not? What do you use instead?

What property type do you use - %TimeStamp? %DateTime?

What is the best practice to have CreatedAt filled automatically during creation and LastUpdated on every successful save (guess it could be in %OnSave)?

Please share your experience /thoughts?

Here’s a special thread where you can tell a bit about yourself — because connecting and learning more about each other is what makes this community great 💬✨

We had a similar discussion on our old Global Masters platform — you might remember! We’re excited to bring that networking opportunity back to the community.

Hey everyone,

I'm diving deeper into Caché ObjectScript and would love to open a discussion around the most useful tips, tricks, and best practices you’ve learned or discovered while working with it.

Whether you're an experienced developer or just getting started, ObjectScript has its own set of quirks and powerful features—some well-documented, others hidden gems. I’m looking to compile a helpful set of ideas from the community.

Some areas I’m especially interested in:

If anyone has a custom checklist of tasks that must absolutely be done when doing this upgrade to make sure everything is included and nothing is lost or destroyed, we would greatly appreciate it? We have the generic checklist provided on the support websites but we run custom build classes, ftp, tcp-ip, batch, etc.

Thanks,

Jonathan Harris

It's been a while since the new UI for Productions and DTL was published as a preview and I would like to know your opinions about it.

WARNING: This is a personal opinion, totally personal and not related with InterSystems Corporation.

I'm going to start with the Interoperabilty screen:

Production screen:

The style is sober and without frills, following the line of cloud services design, I like it.

There is a list of numbers from 1 to 190.

AllList="1,2,3,4,5,6,7,8,9,.....,187,188,189,190"

There is a collection of sets of these values:

List(1)="3,5,6,7,9"
List(2)="1,2,6,9"
List(3)="5,8,9"
List(4)="2,4,6,8"
List(5)="4,7,9"

What is an elegant approach in Object Script to pick the least number of list items:

  • List(1)
  • List(5)
  • List(n)

That together would cover as many numbers as possible from the AllList.

Interested in best coverage over efficiency.

I ask ChatGPT periodically to produce ObjectScript or plain MUMPS code for string manipulation, or for implementing known algorithms etc. Occasionally, it does make mistakes or uses non-existing class members but generally not that bad. Is there any tutorial on the subject of using AI for coding, ideally specifically for ObjectScript/MUMPS? Any AI productivity advice, or tricks you are using, or another AI flavor?

Thanks in advance,
Anna

Background

Embeddings is a new IRIS feature empowering the latest capability in AI semantic search.
This presents as a new kind of column on a table that holds vector data.
The embedding column supports search for another existing column of the same table.
As records are added or updated to the table, the supported column is passed through an AI model and the semantic signature is returned.
This signature information is stored as the vector for future search comparison.

Transforms in COS over DTL

Hi All,

After doing IRIS/Ensemble etc for 20 years I've come across a company who have very odd view, especially about DTL's and routers.

They have convinced themselves to use COS for transforms (including HL7) and for routers (and one of their 3rd party providers agree!)

Their reasons are; efficiency, compatibility, flexibility, power and re-usability.

Of course these reasons are wrong!

Once upon a time in Ensemble Management Portal the pool size of each component (Business Host) within the production was displayed in the Production Configuration page.

This information was very useful, especially when a production have tens or hundreds of components.

It's been a while (and everyone is well-rested after Advent Of Code!) so let's run another round of Code Golf.

Your task is navigating in a grid-like labyrinth in a clockwise spiral pattern. As it traverses the matrix, it collects characters, revealing a secret message.
Your challenge: find the shortest, most elegant code to decode this spiral cipher.
Input:
1. A multidimensional string array with comma separated characters (n x n)
2. Starting coordinates X and Y

Output:
The decoded message as a single string

Hello everyone,

My team is currently developing guidance and best practices for the generation, storage, and deployment of TUNE TABLE statistics across development and production environments. With that in mind, we want to get an idea of what methods teams in the field have developed for handling this data. In particular, we’d like to know the following:

Hi everyone,

I'm looking for a tool that can be used as a base to create an interface that allows a non-technical user to easily forward messages.

The idea is that the user can find an already sent HL7 message and forward it by modifying specific fields of the message without needing any technical knowledge.

An example would be something similar to the Ensemble search engine, but with a less technical and much more intuitive approach and that only allows changing 1 or 2 fields.

The IRIS Installation Guide for Linux, Installation Directory section, says "Do not choose the /home directory, any of its subdirectories, or the /usr/local/etc/irissys directory." but there are no suggestions or any default.

What are your opinions on this? For example, I see that IRIS in a Docker container is installed in /usr/irissys. I'm wondering why that directory was chosen.

The official Linux filesystem docs say:

Is anyone using the IPM client (e.g., running commands like zpm "install somepackagename") on an IRIS version earlier than 2022.1?

We're thinking about raising the minimum supported version so we can use Embedded Python in IPM. I'm curious if this would impact anyone. Of course, you'd be able to continue to use an earlier version of IPM.

The IRIS Management Portal is localized (translated) for some (many?) languages and the language used by the Management Portal interface is determined by the browser settings, often derived from the OS settings (can be changed).

This means that if a user, like me, want to use ONLY the English version of the Management Portal, each and every time you login you need to change the language. VERY annoying.

I know I can change the language configured in Browser, BUT, I want to use English for the IRIS management portal non for all my internet activity!

In the past, I've created custom SQL operations, but now I had something trivial to do, so I decided to take EnsLib.SQL.Operation.GenericOperation out for a spin. There's no example in the docs, so it was a little tricky. Here's what I ended up doing:

In my external database, I have 'mytable' with two fields 'id1' and 'id2'. Here are the pertinent Business Operation settings:
