Message Count

Looking for a SQL query or any other method to find the Unique/distinct message counts for all productions or at least per production namespace within a given time frame. For e.g TimeCreated = January 2025 (Whole month)

I have used the following, but its not restricting the numbers based on the TimeCreated filter. Every time a new message is processed by system, its added to the total. I am running the query in today's date

Select Sum(MsgCount)

From

(Select DISTINCT TargetConfigName, count(DISTINCT SessionID) as MsgCount

FROM ENS.MessageHeader

Some languages ​​have the concept of a garbage collector for automatic memory management. I'd like to know if something like this exists in InterSystems Caché in the context of routines, %CSP.REST, or %CSP.Page.

The question arises from the %Close() method of the %RegisteredObject class. This indicates that I need to manually clear the object from memory if it's no longer in use, or in the web context, if the request has completed. Is this correct? Or am I completely wrong?

Thank you!

This article presents a potential solution for semantic code search in TrakCare using IRIS Vector Search.

Here's a brief overview of results from the TrakCare Semantic code search for the query: "Validation before database object save".

  • Code Embedding model

There are numerous embedding models designed for sentences and paragraphs, but they are not ideal for code specific embeddings.

In my previous article, Using LIKE with Variables and Patterns in SQL, we explored how the LIKE predicate behaves in different scenarios, from Embedded SQL to Dynamic SQL, and what happens to performance when wildcards and variables come into play. That piece was about getting comfortable writing a working LIKE query. But writing SQL that works is only the starting point. To build applications that are reliable, scalable, and secure, you need to understand the best practices that underpin all SQL, including queries that use LIKE.

This article takes the next step. We’ll look at a few key points to help strengthen your SQL code, avoid common pitfalls, and make sure your SELECT statements run not just correctly, but also efficiently and safely. I'll use SELECT statements with LIKE predicate as an example along the way, showing how these broader principles directly affect your queries and their results.

*This is what Gemini came up with for this article, kinda cute.

Code Golf - Maximum Coverage

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.

Using Flask, REST API, and IAM with InterSystems IRIS

Part 1 - REST API

Hello

In this article we will see the implementation of a REST API to perform the maintenance of a CRUD, using Flask and IAM.

In this first part of the article we will see the construction and publication of the REST API in Iris.

First, let's create our persistent class to store the data. To do this, we go to Iris and create our class:

Share volumes across pods and zones on EKS

Background

For a variety of reasons, users may wish to mount a persistent volume on two or more pods spanning multiple availability zones. One such use case is to make data stored outside of IRIS available to both mirror members in case of failover.

Unfortunately the built-in storage classes in most Kubernetes implementations (whether cloud or on-prem) do not provide this capability:

Hello,

as it took me some time to figure out what's wrong, I would like to share this experience, so that you do not fall into the same trap.

I've just noticed that if you name your package "code" (all lowercase), in a class using some embedded python using [Language = python], you'll face the <THROW> *%Exception.PythonException <PYTHON EXCEPTION> 246 <class 'ModuleNotFoundError'>: No module named 'code.basics'; 'code' is not a package

Is there a way in ObjectScript to return the OS user of the superserver? I know %SYS.ProcessQuery can find this for a given process but is there a clean way independent of a specific process ID I can find the OS user used for background jobs?

For IRIS this is usually irisusr and Caché this is usually cacheusr but may vary based on installation and upgrade history of an instance. I would find it very useful to determine programmatically if a process is running as this particular user when the username may vary.

High Availability IAM

One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.

For my hundredth article on the Developer Community, I wanted to present something practical, so here's a comprehensive implementation of the GPG Interoperability Adapter for InterSystems IRIS.

Every so often, I would encounter a request for some GPG support, so I had several code samples written for a while, and I thought to combine all of them and add missing GPG functionality for a fairly complete coverage. That said, this Business Operation primarily covers data actions, skipping management actions such as key generation, export, and retrieval as they are usually one-off and performed manually anyways. However, this implementation does support key imports for obvious reasons. Well, let's get into it.

I have an operation using $ZF this operation ran and did not error but the job has been active and it can not be stopped I have tried stopping it from the front end and through the terminal using ##class(ENSLIB.Job).%New() Stop method. Now my production will not update even if I add a new item to the production I cannot update the item is there a way to force stop this job.

Over time, while I was working with Interoperability on the IRIS Data Platform, I developed rules for organizing a project code into packages and classes. That is what is called a Naming Convention, usually. In this topic, I want to organize and share these rules. I hope it can be helpful for somebody.
