Donderdag 16 april/Thursday April 16th – Speedy Joe’s – Using asynchronous interaction in Java EE to turn the world’s slowest restaurant into a super performant place

Lucas Jellema

De Java SIG (Special Interest Group) van AMIS organiseert op donderdag 16 april een bijeenkomst (publiek toegankelijk) over asynchrone interacties in Java EE (web) applicaties. Synchrone interacties in de echte wereld en in IT applicaties kunnen de boel behoorlijk ophouden. Synchroon betekent wachten – en resources vasthouden. Dat kan een […]

What is REST?

Maarten Smeets

REST (Representational State Transfer) is a term often used in software engineering when talking about services or other API’s. A lot of these so-called RESTful services or interfaces are not RESTful at all. Even the author of REST gets frustrated by the common misuse; http://roy.gbiv.com/untangled/2008/rest-apis-must-be-hypertext-driven: “I am getting frustrated by the number of people […]

OTN article: Speedy Perception trumps Speed Reception – on Smart Asynchronous Interactions in multi layered architectures

Lucas Jellema

The Oracle Technology Network has just published my article on asynchronous interactions used in multi-layered architectures to free up resources and create at least the perception of speedy processing. This article describes how, by leveraging opportunities for asynchronous processing, at least the perceived responsiveness of our systems is likely to […]

ADF Performance Monitor: Customer Case Video

Frank Houweling

The ADF Performance Monitor is designed for measuring, analyzing, tuning, and checking the performance of Oracle ADF applications. The monitor can track and collect crucial (production) performance information of the application’s runtime ADF components that are not standard provided by Oracle. It helps development, QA, and operation teams to detect, […]

ADF Performance Monitor: Detecting and Analyzing a High ADF BC Memory Consumption

Frank Houweling 2

Like other web applications, Oracle ADF applications potentially use a lot of JVM memory. Many times, the root cause of a high memory usage is that application data retrieved from the database into memory is not properly limited; hundreds or thousands of rows (with too many attributes) are fetched and […]
