clip_image002Introduced in Weblogic 12.1.2, dynamic clusters is a great feature to scale your private cloud.
Dynamic clusters provides you easy scaling of Weblogic clusters by adding and removing managed server instances on demand. They contain one or more dynamic servers. These dynamic servers are based on a single servertemplate that guarantees that every member of the cluster is exactly the same.

Creating Dynamic Clusters

Let’s take a look at some of the possibilities as we create a dynamic cluster.

I have created a virtualbox environment.
This environment consists of four VM’s with the following specs.

  • 2 vCPU’s
  • 4 Gb memory
  • 50 Gb disk
  • Oracle Linux 6.6
  • Java 1.7.0_75
  • Weblogic 12.1.3.0.2

I created a simple domain called demo_domain with only an AdminServer and four machines.
After unpacking the domain to the four servers, the nodemanagers where started and are reachable by the AdminServer.

Now let go through the process of creating a dynamic cluster.
Open the Weblogic Console and navigate to Environment -> Clusters
Lock and Edit the domain in the Change Center. Read the complete article here.

clip_image002My 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. So decided to create a Linux VM – actually a Virtual Box VM – that would serve as my Docker host.

In this article I will walk through the steps I went through in order to get this Linux VM running on my Windows host and subsequently turn that VM into the Docker Server in which one or more containers will be running – eventually to serve as demo and training environments, for example with Oracle Databases and Middleware. After all, Mark Nelson showed the way in this wonderful article: https://redstack.wordpress.com/2014/11/14/gettingn-to-know-docker-a-better-way-to-do-virtualization/.

I decided to closely follow Mark’s lead in his choice of Linux VM: Ubunty 14.04.1, to be created using Vagrant (about which I have blogged before – for example https://technology.amis.nl/2014/06/26/provisioning-an-oracle-11g-database-virtualbox-vm-with-vagrant-and-puppet-for-dummies/ ).

Stage One – Create Ubuntu VM using Vagrant

I have both Vagrant and Virtual Box set up on my laptop. From that starting point, I open a command line window and create directory into which to create the Vagrant configuration for the VM. Read the complete article here.

clip_image002We are very excited to announce that Oracle WebLogic Server is now certified to run on Docker containers. As part of the certification, we are releasing Dockerfiles and supporting scripts on GitHub to build images for Oracle WebLogic Server.  These images are built as an extension of existing Oracle Linux images Oracle Linux Images. You can use these Oracle WebLogic Server Docker images or create your own. To help you with this, we have posted Dockerfiles and scripts on GitHub as examples for you to get started.

Docker is a platform that enables users to build, package, ship and run distributed applications. Docker users package up their applications, and any dependent libraries or files, into a Docker image. Docker images are portable artifacts that can be distributed across Linux environments. Images that have been distributed can be used to instantiate containers where applications can run in isolation from other applications running in other containers on the same host operating system.

The table below describes the certification provided for various WebLogic Server versions. You can use these combinations of Oracle WebLogic Server, JDK, Linux and Docker versions when building your Docker images. Read the complete article here.
