Key take-aways from the Oracle PaaS Cloud announcements – Integrate, Accelerate, Lead

imageMonday June 22nd was the launch date for Oracle for 24 (and more) Cloud Services. June is traditionally an important month for Oracle when it comes to product launches and important announcements. This year is the same in that respect. The announcements came in a many-hour live webcast including a 45 minute presentation by Oracle CTO Larry Ellison (see videos from Oracle Cloud Platform Launch). I have harvested some of the most relevant slides (more...)

De business case voor vervanging van maatwerksoftware

IT-projecten rond maatwerk software voldoen vaak niet aan de financiële verwachtingen. Niet zelden is een voorname oorzaak dat naast de functionele uitbreidingen waar de business case en het budget op gebaseerd zijn, ook een flinke technische inhaalslag moet worden gemaakt die niet expliciet in de begroting is opgenomen.

Vervanging van maatwerksoftware drukt zwaar op de begroting, waardoor uitstellen vaak makkelijker is dan vervanging. Ik verbaas me hier over, want het is toch bekend dat maatwerksoftware (more...)

Stream Explorer and JMS for both inbound and outbound interaction

In this article, we will look at the very common interaction between Stream Explorer and JMS. JMS is a commonly used channel for decoupled exchange of messages or events. Stream Explorer can both consume messages from a JMS destination (through Stream) and publish findings to a JMS destination (with a target). The use case we discuss here is about temperature sensors: small devices distributed over a building, measuring the local room temperature every few seconds (more...)

Interacting with JMS Queue and Topic from Java SE

This article is just a quick post of some code I want to have easy access to. It runs in Java SE – outside any container in a stand alone JVM. It creates a connection with a JMS Queue. One class sends messages to the Queue, the other class registers as a listener and consumes messages from a different queue.

StreamExplorer pushing findings as JSON messages to a WebSocket channel for live HTML Dashboard updates

A common desire when doing real time event processing with Stream Explorer and/or Oracle EVent Processor is the ability to present the findings from Stream Explorer in a live dashboard. This dashboard should hold a visualization of whatever information we have set up Stream Explorer to find for us – and it should always show the latest information.

User interfaces are commonly presented in web browsers and created using HTML(5) and JavaScript. As part of (more...)
