InterSystems Data Platforms and performance – Part 1

Caché, System Admin, Performance

Your application is deployed and everything is running fine. Great, hi-five! Then out of the blue the phone starts to ring off the hook – it’s users complaining that the application is sometimes ‘slow’. But what does that mean? Sometimes? What tools do you have and what statistics should you be looking at to find and resolve this slowness? Is your system infrastructure up to the task of the user load? What infrastructure design questions should you have asked before you went into production? How can you capacity plan for new hardware with confidence and without over-spec'ing? How can you stop the phone ringing? How could you have stopped it ringing in the first place?

Caché Class Explorer — exploring Caché in the UML notation

Caché, Tools, Caché ObjectScript (COS), VIsualization


Hello!

This article is a small overview of a tool that helps to understand classes and their structure inside the Caché DBMS.

In short, it visualizes a class or an entire package, shows the relations between classes and provides all the possible information to developers and team leads without making them go to Caché Studio and examine the code there.

If you are learning InterSystems Caché, reviewing Caché projects a lot or just interested in something new in InterSystems Technology solutions — you are more than welcome to read the overview of Caché Class Explorer!

How we learned to stop worrying and love InterSystems Ensemble

Caché, Studio, Ensemble

 

Preface: our small, but very ambitious company called “Black Mushroom Studio” came up with an idea for an e-commerce project and a mobile app that would let users pay for certain goods/services via a payment aggregator.

 

What we had initially: an Android app skeleton that, of course, liked communicating via HTTP and JSON, and a payment system with an API – web services with SOAP content.

 

Goal: make it all work together.

Provision a Caché application using Ansible - Part 1

Caché, System Admin

Ansible helped me solve the problem of quickly deploying Caché and application components for Data Platforms benchmarks. You can use the same tools and methodology for standing up your test labs, training systems, development or other environments. If you deploy applications at customer sites you could automate much of the deployment and ensure that system, Caché and your application are configured to your applications best practice standards.

Class Queries in InterSystems Caché

Caché, Caché Objects, Languages, Caché ObjectScript (COS), SQL, Stored Procedures

Class Queries in InterSystems Caché is a useful tool that separates SQL queries from Caché Object Script code. Basically, it works like this: suppose that you want to use the same SQL query with different arguments in several different places.In this case you can avoid code duplication by declaring the query body as a class query and then calling this query by name. This approach is also convenient for custom queries, in which the task of obtaining the next row is defined by a developer. Sounds interesting? Then read on!
