Optimizing Performance of Apache Web Server and Web Gateway

Until now i used $ZF(-1), in older Caché versión, now I try to use $ZF(-100), i do:

REST>w $ZV
Cache for Windows (x86-64) 2018.1.4 (Build 505_1) Thu May 28 2020 10:12:49 EDT
REST>s a=$zf(-100,"/SHELL","dir")
 
S a=$ZF(-100,"/SHELL","dir")
^
<NOTOPEN>

What is wrong?

Thanks in advance

I'm following this guide as well as the sample.cs file and getting an error message on this line

cache_connection.Connect();

The error is:

Caught GlobalsException: lc_conn::connect_device returned Db_err: source: lc_conn::connect() message: lc_conn::connect: CacheSecureStart returned -15: <ACCESSDENIED>

🛠️ Managing KONG Configurations in CI/CD with InterSystems IRIS IAM

🔍 Context: InterSystems IRIS IAM & Kong Gateway

As part of integrating InterSystems IRIS into a secure and controlled environment, InterSystems IRIS IAM relies on Kong Gateway to manage exposed APIs. Kong acts as a modern API Gateway, capable of handling authentication, security, traffic management, plugins, and more.

JSON

JSON (JavaScript Object Notation) is a lightweight, text-based format designed for structured data interchange. It represents data objects consisting of key–value pairs and arrays, and it is entirely language-independent.

⏯️ The Ultimate 3D Industrial Simulation powered by a Game Engine with InterSystems IRIS

In this demo, InterSystems IRIS Interoperability comes alive in an amazing, game-like user experience based on our Ultimate Control Tower demo. We visualize machines in a virtual 3D factory building, interacting with InterSystems IRIS in real time—displaying current statuses and sensor data, simulating machine outages and predictive maintenance scenarios, and triggering workflow tasks and actions in InterSystems IRIS. By using a mobile app on a tablet—and even a VR headset for a fully immersive experience—we unleash the power of InterSystems IRIS.

Hello everyone,

I'm using EnsLib.TCP.TextLineOutboundAdapter to communicate with a third-party system over TCP/IP. The issue is that the system sends back only an integer (e.g. 1001 or -1) without any terminator (like $c(10)).

I'm trying to print from Cache and I have setup the device, but keep getting a message that someone else is using it. this is RHEL 7.9. I have cups running and I can print from the command line. I have also issued this command: lpadmin -p KM501L -u allow:all

what am I missing

thanks

Paul

Hey Community,

Last week, the InterSystems team held our monthly Developer Meetup in a new venue for the first time ever! In the AWS Boston office location in the Seaport, over 71 attendees showed up to chat, network, and listen to talks from two amazing speakers. The event was a huge success; we had a packed house, tons of engagement and questions, and attendees lining up to chat with our speakers afterwards!

Good morning everyone,

Hi Community!

We’re pleased to announce that several Early Access Programs (EAPs) are now open for registration. These programs provide developers with the opportunity to explore upcoming features and technologies from InterSystems before their general release.

By joining an EAP, you can:

• Evaluate and test new functionality
• Provide direct feedback to product teams
• Help shape the future direction of InterSystems platforms

If you're interested in contributing to the evolution of our tools and getting early insight into what's coming next, we encourage you to review the following available programs and sign up:

This will be an introduction to Python programming in the context of IRIS.

Before anything I will cover an important topic: How python works, this will help you understand some issues and limitations you may encounter when working with Python in IRIS.

All the articles and examples can be found in this git repository: iris-python-article

Hello Again,

InterSystems Certification is still looking for people to beta test the InterSystems IRIS SQL Professional Certification exam. This is a great way to earn the certification for free! We have extended the deadline of the beta test to August 31, 2025.

Faced with the enormous and evergrowing amounts of data being generated in the world today, software architects need to pay special attention to the scalability of their solutions. They must also design systems that can, when needed, handle many thousands of concurrent users. It’s not easy, but designing for massive scalability is an absolute necessity.

Software architects have several options for designing scalable systems. They can scale vertically by using bigger machines with dozens of cores. They can use data distribution (replication) techniques to scale horizontally for increasing numbers of users. And they can scale data volume horizontally through the use of a data partitioning strategy. In practice, software architects will employ several of these techniques, trading off hardware costs, code complexity, and ease of deployment to suit their particular needs.

This article will discuss how InterSystems IRIS Data Platform supports vertical scalability and horizontal scalability of both user and data volumes. It will outline several options for distributing and partitioning data and/or user volume, giving scenarios in which each option would be particularly useful. Finally, this paper will talk about how InterSystems IRIS helps simplify the configuration and provisioning of distributed systems.

As foreign tables are behind a paywall (booo); we have a external cache system using the intersystems ODBC driver or usually a .jar CacheDB.jar.

The requirement is :

"Create a copy of the external table once a day to perform comparisons to detect changes"

We could go full code and this is what we will do but trying the following should ideally work
