Abstract

A global provider of mobile telecommunications software tested the performance of InterSystems Caché and Oracle as the database in a simulated data mart application. They found Caché to be 41% faster than Oracle at building a data mart. When testing the response time to SQL queries of the data mart, Caché's performance ranged from 1.8 times to 513 times faster than Oracle.

Introduction

This is a nice introductory explanation of MQTT that I thought would be of general interest. The technology used for the broker in this case is not that important as there are several brokers available.

At global summit we will be demonstrating ways to use MQTT with Ensemble to get information from the Internet of Things into your enterprise applications and business processes,

There have been a few use cases recently within InterSystems where we've needed to connect to Caché-based web services from PHP. The first of these was actually the Developer Community itself, which uses web services as part of Single Sign-On with other InterSystems sites/applications. The following example demonstrates how to connect to a Caché-based web service (particularly, the web service in the SAMPLES namespace) from PHP, using password authentication.

Presenter: Luca Ravazzolo
Task: Track the status and performance of clustered environments
Approach: Give examples of using modern technology to spot potential bottlenecks before they turn into problems

This session will discuss how modern technology can be used to keep track of the status and performance of your cloud clustered environments.

Presenter: Alex MacLeod
Task: Understand and use IHE in HealthShare
Approach: Provide a real-world example of a successful IHE implementation

In this session, we will discuss the basics of IHE in HealthShare, as well as share a real world example of a successful IHE implementation.

Hi everyone,

I've created an Identicon Generator inspired on Fabio Gonçalves Captcha Validator.

This sample can be used to create Identicons for users of app for example, it can be useful to use in Zen Mojo applications, generating an identifier image based on name of the user by example, but it can be used in others kind of applications too(Zen, CSP etc)

This is a series of programming challenges for beginners and experienced Caché programmers.

Today, you have to find a path through a maze. To know if a coordinate is a wall or an open space, you will have to do a calculation like this :

Often InterSystems technology architect team is asked about recommended storage arrays or storage technologies. To provide this information to a wider audience as reference, a new series is started to provide some of the results we have encountered with various storage technologies. As a general recommendation, all-flash storage is highly recommended with all InterSystems products to provide the lowest latency and predictable IOPS capabilities.

The first in the series was the most recently tested Netapp AFF A300 storage array. This is middle-tier type storage array with several higher models above it. This specific A300 model is capable of supporting a minimal configuration of only a few drives to hundreds of drives per HA pair, and also capable of being clustered with multiple controller pairs for tens of PB's of disk capacity and hundreds of thousands of IOPS or higher.

Running a Background Job using the JOB command is a well-known feature.
Using ECP to distribute databases to several servers is also well-known.
But using the combination of both to run a process on a different server
seems to be a rare case.

Sure there are enough other ways to start a remote job, but the special
combination with ECP where the application server starts a process on a
data server without additional networking is worth to be remembered.

Currently, many of you has some knowledge about CachéQuality (which is being renamed to objectscriptQuality) for analyzing objectscript code using the rules we have predefined. Probably you have tested it and have found too many warnings in your projects. I'm sure there are issues which are really important for you and some others which you would like to dismiss.

One of the things I want from VSCode is to have a familiar Studio look.

Thankfully VSCode is easily customizable so you can choose any color for any element.

Here's what I got so far:

To get the same look add to your settings.json:

Following up the previous part, it's time to take advantages for IntegratedML VALIDATION MODEL statement, to provide information in order to monitor your ML models. You can watch it in action here

In this article, we'll talk about an application that I use every day when monitoring applications and integration solutions on the InterSystems IRIS platform and finding errors when they occur.
