It helps to remove special characters, such as non-utf-8 characters either control characters or unicode characters from text that is not printable or can't be parsed by downstream systems.

There is also $C(32) in this condition; sometimes NBSP appears in the text and it will not be recognized by TIE, but downstream it displays as "?".

Hi Community!

We know that every developer has small side projects — apps where you experiment with new technologies, test ideas before implementing them in bigger solutions, or just build something fun for the sake of curiosity. But what if one of those projects could take you all the way to the InterSystems READY 2025?

We’re launching a unique opportunity: show us your passion, creativity, and love for IRIS, and win a free pass to the InterSystems READY + hotel accommodation!

The rules are simple: upload your fun IRIS-based side project to Open Exchange, and record a short inspirational video about why you should be the one to get the pass to THE event of the year and win!

Duration: April 21 - May 04, 2025

Prizes: hotel accommodation and free passes to the InterSystems READY 2025!

Sometimes customers need a small IRIS instance to do something in the cloud and shut it down, or they need hundreds of containers (i.e. one per end user or one per interface) with small workloads. This exercise came about to see how small an IRIS instance could be. For this exercise we focused on what is the smallest amount of memory we can configure for an IRIS instance. Do you know all the parameters that affect the memory allocated by IRIS ?

RabbitMQ is a message broker that allows producers (those who send a data message) and consumers (those who receive a data message) to establish asynchronous, real-time, and high-performance massive data flows. RabbitMQ supports AMQP (Advanced Message Queuing Protocol), an open standard application layer protocol.
The main reasons to employ RabbitMQ include the following:

  • You can improve the performance of the applications using an asynchronous approach.
  • It lets you decouple and reduce dependencies between services, microservices, and applications with the help of a data message mediator, meaning that there is no need for producers and consumers of exchanged data to know each other.
  • It allows the long-running processing of sent data (with the results) to be delivered after utilizing a response queue.
  • It helps you migrate from monolithic to microservices, where microservices exchange data via Rabbit in a decoupled and asynchronous way.
  • It offers reliability and resilience by making it possible for messages to be stored and forwarded. A message can be delivered multiple times until it is processed.
  • Message queueing is the key to scaling your application. As the workload increases, you will only have to add more workers to handle the queues faster.
  • It works well with data streaming applications.
  • It is beneficial for IoT applications.
  • It is a must for Bots’ communication.

The Good Old Days

The %Library.DynamicObject class has been in IRIS since before it became IRIS. If you have been using it since the Cache days, you may want to brush up on some of its changes.

In Cache 2018, the %Get method only had one argument. It was the key to retrieving from the JSON, meaning that if your JSON object called myObj, it would look like the following:

Global mapping priority

Hi,

If I map all globals with (*) to a database1, then would like to map specific only some globals eg. MYGLOB* to be located in a different database2, which mapping will override the other, so would all globals that starts with MYGLOB* be placed in database1 or 2?

Thanks

If one of your packages on OEX receives a review you get notified by OEX only of YOUR own package.
The rating reflects the experience of the reviewer with the status found at the time of review.
It is kind of a snapshot and might have changed meanwhile.
Reviews by other members of the community are marked by * in the last column.

Minify XML in IRIS

In a project I'm working on we need to store some arbitrary XML in the database. This XML does not have any corresponding class in IRIS, we just need to store it as a string (it's relatively small and can fit in a string).
Since there are MANY (millions!) of records in the database I decided to reduce as much as possible the size without compressing. I know that some XML to be stored is indented, some not, it varies.

Embedded Python query

Hi Guys,

How can I use this same objectscript principle in embedded python to get the value of each field in my loop?

s sql="SELECT ID, Name, Age FROM Sample.Person WHERE Age="_Myage

Set RS=##class(%ResultSet).%New()

Set Ret=RS.Prepare(sql)

Set Ret=RS.Execute()

While RS.Next()

{

Set name=RS.GetData(2)

}

I ran into a situation where VS Code consumed all available web sessions and was unable to get to the Management Console to clear them. I was able to establish a terminal session, though.

Is there a method or routine available through the IRIS terminal that allows one to clear web sessions? I've searched the administration and class documentation and haven't found a solution.

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.

Migrating from Oracle, MSSQL, or other purely relational database systems to a multimodel InterSystems IRIS is a strategic decision that requires careful planning and execution. While this transition offers significant benefits, including enhanced performance, scalability, and support for modern architectures, it also comes with challenges. In this article I will highlight some of the considerations connected to coding to ensure a successful migration. I will leave everything connected to an actual migration of structures and data outside the scope of this article.


First, when you're considering migrating to a different database system, you need to understand your business logic, whether it's on the side of the application (application server) or the database server. Basically, where do you have your SQL statements that you will need to potentially rewrite?

Hi developers!

While developing web apps the security practice I consider safe and convenient is to create a special Role (e.g. equal application name) which contains security resources which application will need (SQL tables, priviledges, database access, etc) and assign it to the Web Application.
So the user gets this role once it loggs in to the application (via password, no password or delegated).

Convenient, right?

So, the question is, when I deploy the app as an IPM module what should I put as a database access?

When working with InterSystems IRIS, database developers and architects often face a critical decision: whether to use Dynamic SQL or Embedded SQL for querying and updating data. Both methods have their unique strengths and use cases, but understanding their performance implications is essential to making the right choice. Response time, a key metric in evaluating application performance, can vary significantly depending on the SQL approach used. Dynamic SQL offers flexibility, as queries can be constructed and executed at runtime, making it ideal for scenarios with unpredictable or highly variable query needs. Conversely, Embedded SQL emphasizes stability and efficiency by integrating SQL code directly into application logic, offering optimized response times for predefined query patterns.

In this article, I will explore the response times when using these two types of SQL and how they depend on different class structures and usage of parameters. So to do this, I'm going to use the following classes from the diagram:
