Next step with Docker – Create Image for Oracle Database 12c using Puppet

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/).

Docker – Take Two – Starting From Windows with Linux VM as Docker Host

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...)

My First Steps with Docker – starting from Windows as the Host

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...)

Quick Introduction to Oracle Stream Explorer Part Three– Business User friendly processing of real time events – some smart pattern detection

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...)

Quick Introduction to Oracle Stream Explorer Part Two– Business User friendly processing of real time events (enrichment, calculation)

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.

Quick Introduction to Oracle Stream Explorer – Business User friendly processing of real time events

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...)

SOA Suite: How to set database session context through Database Adapter – and how to retrieve data from V$SESSION

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...)
