In a previous article – https://technology.amis.nl/2015/03/15/docker-take-two-starting-from-windows-with-linux-vm-as-docker-host/ – I have discussed my first steps with Docker. With Windows as my host environment I used Vagrant to create a VirtualBox VM with Ubuntu. In that VM I installed Docker can played around creating some containers, images and eventually an image for Oracle WebLogic 12.1.3. I leveraged the excellent work by Mark Nelson (especially his article https://redstack.wordpress.com/2014/11/14/gettingn-to-know-docker-a-better-way-to-do-virtualization/).
In this article I (more...)
My first attempt with Docker was from my Windows host machine using boot2docker, as described in this article: https://technology.amis.nl/2015/03/15/my-first-steps-with-docker-starting-from-windows-as-the-host/. Boot2docker is a great tool for being able to work with Docker on a Windows machine. However, I ran into limitations – such as not being able to create containers with the GUI applications running in them. Besides, Linux seems to be – for now at least – the more natural environment for Docker. (more...)
After reading quite a bit about Docker – especially the great write up by Mark Nelson (Getting to know Docker – a better way to do virtualization?) I believe it is more than about time for me to delve a little further into Docker. Following Edwin Biemond’s lead, I have dabbled quite a bit in Vagrant and Puppet and had quite satisfying results. The attraction of Docker – the even leaner way of (more...)
This article is part three in a series about Oracle – very recently released by Oracle and available from OTN. With Oracle Stream Explorer, business users and citizen developers as well as hard core developers can create explorations on top of live streaming data to filter, enrich, aggregate, inspect them and detect patterns. Stream Explorer provides a business user friendly browser based user interface in which streams are configured, explorations are composed, enrichment is set (more...)
Very recently, Oracle released the Oracle Stream Explorer product, available from OTN. With Oracle Stream Explorer, business users and citizen developers as well as hard core developers can create explorations on top of live streaming data to filter, enrich, aggregate, inspect them and detect patterns. Stream Explorer provides a business user friendly browser based user interface in which streams are configured, explorations are composed, enrichment is set up and publication to external consumers is defined. (more...)
The new Oracle Stream Explorer provides us with a [business]user friendly facility to process real time events. Through visually appealing and functionally intuitive web wizards, Stream Explorer has us construct explorations that consume events from streams, process these events through filtering, aggregation, pattern matching and enriching and deliver these events to downstream destinations.
Using Stream Explorer, we can tap into streams of events – frequently JMS messages and alternatively HTTP PUB/SUB, SOA Suite EDN events (more...)
This article continues the story from Mobile backend with REST services and JSON payload based on SOA Suite 12c for Live Mobile Hacking with an OFM 12c red stack – Part 1. It is the story of how to expose SOAP/XML based Web Services – primed for enterprise integration and process automation – as REST services with URL parameters and JSON payloads that provide the mobile backend APIs required for the development of mobile apps.

To allow the Oracle Database to produce meaningful log, audit trail and trace information that allow problem analysis of issues and interpretation and optimization of run time behavior, it is necessary that the database session execution context is set. Without it, efficient administration of the RDBMS is not possible. This context that should be set by any consumer of the database consists of aspects such as who (is the user for which the database is (more...)
