In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:
InterSystems Data Platform includes utilities and tools for system monitoring and alerting, however System Administrators new to solutions built on the InterSystems Data Platform (a.k.a Caché) need to know where to start and what to configure.
This guide shows the path to a minimum monitoring and alerting solution using references from online documentation and developer community posts to show you how to enable and configure the following;
Caché Monitor: Scans the console log and sends emails alerts.
System Monitor: Monitors system status and resources, generating notifications (alerts and warnings) based on fixed parameters and also tracks overall system health.
Health Monitor: Samples key system and user-defined metrics and compares them to user-configurable parameters and established normal values, generating notifications when samples exceed applicable or learned thresholds.
History Monitor: Maintains a historical database of performance and system usage metrics.
pButtons: Operating system and Caché metrics collection scheduled daily.
Remember this guide is a minimum configuration, the included tools are flexible and extensible so more functionality is available when needed. This guide skips through the documentation to get you up and going. You will need to dive deeper into the documentation to get the most out of the monitoring tools, in the meantime, think of this as a set of cheat sheets to get up and running.
Welcome to the very first Supported Platforms Update! We often get questions about recent and upcoming changes to the list of platforms and frameworks that are supported by the InterSystems IRIS data platform. This update aims to share recent changes as well as our best current knowledge on upcoming changes, but predicting the future is tricky business and this shouldn’t be considered a committed roadmap.
We’re planning to publish this kind of update approximately every 3 months and then re-evaluate in a year. If you find this update useful, let us know! We’d also appreciate suggestions for how to make it better.
In this article I would like to present the RESTForms project - generic REST API backend for modern web applications.
The idea behind the project is simple -after I wrote several REST APIs I realized that generally, REST API consists of two parts:
Work with persistent classes
Custom business logic
And, while you'll have to write your own custom business logic, RESTForms provides all things related to working with persistent classes right out of the box. Use cases
You already have a data model in Caché and you want to expose some (or all) of the information in a form of REST API
You are developing a new Caché application and you want to provide a REST API
Hi All This is the index to a series of articles I hope to create over the coming months.
ZEN and ZEN Mojo are no longer being actively developed by Intesystems - this is a great shame as it is a fine product that works so well for business applications. However ZEN is a 15 year old product and I need a path forward to replace the ZEN UI with a supported development framework.
This article is an index of the other articles I have, or plan to write. - the articles will be subject to change as I develop my thoughts and climb the learning curve.
Hello everyone, First sorry for the ignorance, but, as I am new in the InterSystem world, I came to the following doubt: Thinking about a database migration.Is it possible, in a non-traumatic way, to take an Oracle database and migrate it completely to Caché?
During a major version upgrade it is advisable to recompile the classes and routines of all your namespaces (see Major Version Post-Installation Tasks).
The Caché / Ensemble standard distribution contains in namespace SAMPLES a nice example of a CSP page consuming WebService as a Client. I have modified it not only to display the replies but to feed them back into a Global. I used the classic Hyperevent to achieve this. The replies end up as a log in global^WSREPLY. When there is no input anymore the page closes and goes away.
There are 2 versions with visible and hidden display during operation. dc.WSCSP.reverseVerbose.cls and dc.WSCSP.reverseHidden.cls
InterSystems IRIS family has a nice utility ^SystemPerformance (as known as ^pButtons in Caché and Ensemble) which outputs the database performance information into a readable HTML file. When you run ^SystemPerformance on IRIS for Windows, a HTML file is created where both our own performance log mgstat and Windows performance log are included.
This post is dedicated to the task of monitoring a Caché instance using SNMP. Some users of Caché are probably doing it already in some way or another. Monitoring via SNMP has been supported by the standard Caché package for a long time now, but not all the necessary parameters are available “out of the box”. For example, it would be nice to monitor the number of CSP sessions, get detailed information about the use of the license, particular KPI’s of the system being used and such. After reading this article, you will know how to add your parameters to Caché monitoring using SNMP.
This post provides guidelines for configuration, system sizing and capacity planning when deploying Caché 2015 and later on a VMware ESXi 5.5 and later environment.

Despite the fact that InterSystems has long recommended using external backup tools, many users have opted to use the internal Online Backup facility, which is included in all distributions of InterSystems products (IRIS Data Platform, Caché, etc.). The reasons why are quite obvious:
As Bill has mentioned earlier in his post, we have carefully reviewed the JSON capabilities and made some adjustments to ensure they deliver the best benefit to you. In this post, I am going to describe the modifications in more detail and provide guidance for you to understand the implication for your code base.
Apache Spark has rapidly become one of the most exciting technologies for big data analytics and machine learning. Spark is a general data processing engine created for use in clustered computing environments. Its heart is the Resilient Distributed Dataset (RDD) which represents a distributed, fault tolerant, collection of data that can be operated on in parallel across the nodes of a cluster. Spark is implemented using a combination of Java and Scala and so comes as a library that can run on any JVM.
I'm facing a specific sort problem. There are several thousands of articles sold all over. Users expect to get a description in local language sorted by their specific collation.
$LIST string format and %DynamicArray and %DynamicObject classes
IRIS, and previously Cache, contain several different ways to create a sequence containing a mixture of data values. A data sequence that has been available for many years is the $LIST string. Another more recent data sequence is the %DynamicArray class, which along with the %DynamicObject class, is part of the IRIS support for JSON string representation. These two sequences involve very different tradeoffs.
Pouring The Coffee: Creating and scheduling a task
Don't you wish a fresh, hot cup of coffee could be waiting for you right when you get into the office? Let's automate that!
Cache and IRIS come with a built-in Task Manager, which should have a familiar feel to those used to using the Windows task scheduler or using cron on Linux. Your user account will need access to the %Admin_Task resource to use it, and you can access it in the management portal under System Operation -> Task Manager. When first installed, there are roughly 20 types of task that you can schedule.
Have you ever thought what could be a reason why some development environment (database, language) would eventually become popular? What part of this popularity could be explain as language quality? What by new and idioms approaches introduced by early language adopters? What is due to healthy ecosystem collaboration? What is due to some marketing genius?
A few people wrote to me asking about the infrastructure behind the Atelier Server implementation. Its neat and a worthwhile story to share so I am writing it up here as a post on the community. I want to go in to a little detail on why it was needed and then I will outline in detail how we went about implementing this.
I wanted to share a little tidbit which is in the Studio documentation (http://docs.intersystems.com/cache20152/csp/docbook/DocBook.UI.Page.cls?...) but many people who have been using the InterSystems Studio for a long time missed the addition of this *very* useful feature, and every time I mention this to an audience I see at least one face light up because of how excited they are to learn about it!
Within Studio, the Output pane (View -> Output) is actually misnamed. It is actually an Input/Output window which can be used to run Caché ObjectScript commands!
