Vagrant + Ansible + Oracle

So, I finally got my act together and created the repositories I’ve been meaning to create for ages, to automatically spin up a VM running Oracle. They are: and uses Vagrant to provision the machine, and then Ansible to automatically provision Oracle. The readme’s for each repository should (hopefully) be enough to get […]

#Javaland 2017 wrap up

Yes – I did it again and attend Javaland conference in Phantasialand Brühl.

It was not easy this year to concentrate on the sessions because of the hottest march of the last 100 years. But the quality of the sessions beats the weather. Maybe again my invest in reading the abstracts and filter the sessions before the conference has payed off.

Oracle Linux Vagrant boxes

I use Vagrant a lot. It is an awesome tool when it comes to quickly spin up a local VM for some testing. All my boxes are stored on Hashicorp’s Atlas. Atlas provides a lot more functionality than just being a box repository, but I only use it for just that. I try to create one […]

Virtual Development Server: Provide Docker images in docker registry for Oracle via Jenkins

This is a follow up to earlier Virtual Development Server: Provide Docker images in docker registry for Oracle XE Database and others.

We now try to automated build of all needed images as soon as Oracle GitHub Sources changed or we need to build our Vagrant VirtualBox again from scratch.

After we have already installed Jenkins we now install first some needed plugins.

We select explicit plugins at Jenkins Configuration: Pipeline and Pipeline Stage View Git SSH Slaves and wait for the install process Later we add Blue Ocean Beta via "Manage Jenkins" -> "Manage Plugins" . After all is installed we restart Jenkins.

After this we create our Jenkins pipeline via “New Item”.

We give it a name and select pipeline. As we do not own the git repository and cannot create a hook there, we create a simple scm poll schedule. Then we add our pipeline script.

Here is the script (more...)

Virtual Development Server: Install Jenkins for Continuos Integration / Delivery / Deployment


For automation of all of my processes I need Jenkins in my development server.

First I had installed Jenkins as Docker container via Vagrant Docker provider. But with this architecture it was very complicated to create docker images and run Docker containers on the Docker host, in this case my Vagrant Virtualbox.

So for simplification I have decided to install Jenkins with the provisioning of the Vagrant Virtualbox via a shell provider in my Vagrantfile:


VirtualBox Manual DPK Import Failure: Ran out of Virtual Disk

The DPK scripts are simply amazing. I enjoy the flexibility of the new DPK system. I will confess, creating an HCM demo environment with DPK is not as easy as the prior PUM image method, but it is pretty close. As I prepared for OpenWorld 2016, I thought I would download the latest HCM DPK (update 18) and build out a new demo server on my MacBook. Unfortunately, I wasn't able to use the standard (more...)

Virtual Development Server: Provide Docker images in docker registry for Oracle XE Database and others

For later creation of containers as needed in the deployment process we have first to build docker images whenever we do not find suitable one in docker hub.

For most of my development I need a oracle database. On the internet you can find a lot of Dockerfile’s for this, but no ready image. This is because for running a database you have to accept a license and this happens when you download the installation (more...)

Virtual Development Server: Add swapfile to VirtualBox as requirement for installing Oracle or build Oracle docker images

As I want later build Oracle docker images, some of this need a swapfile.

Per default my used Vagrantbox, does not have one, so later steps will fail.

As in the last blog I use a Vagrant shell provider.

  # add swapfile to the box
  config.vm.provision :shell, :path => ""

This calls the script in the created VirtualBox machine.
Make sure, that you create your swapfile on a supported (more...)

Virtual Development Server: Add enough ram and disk space to VirtualBox for further server components

As I want later build docker images and run docker containers I have to provide enough disk space for this.

Per default the Vagrantboxes have vmdk disks, these have a static size and are to small for my purposes.

Therefore I convert the disk, which comes with the box, via Vagrant VirtualBox provider from vmdk to vdi, so that it allocate only the used disk space in the host system.
Additional I add a second (more...)

Developer Days VM Startup and Shutdown, SQLcl

| Jun 16, 2016
If you're developing on a remote platform, chances are that you are using a Virtual Machine. (VM)  In Oracle, we release a virtual machine called the  "Oracle Developer Days".    This is available on the Oracle Technology Network and ala google.  Todays hack is setting up headless vm's, ports and aliases to speed up your day. (This post took a lot longer to write that the aliases we set up!)

For this (more...)

VirtualBox 5.0.16 Released….

As always, Tim Hall was the first to find it out :=) . So if you haven’t done already-update your VirtualBox setup to VirtualBox 5.0.16 version. I have done the update on my laptop (this one, Win 7 Professional) and desktop(Win 7 Professional) with no issues.

Have upgrading!

Oracle VM file sharing with Windows host

racattack, meet ansible-oracle!

A while back I was approached by Jeremy Schneider, who is one of the original contributors to the racattack project and he wanted to know if I was interested in integrating ansible-oracle with the RAC Attack automation project, and of course I was! The idea was to provide a completely hands off installation of an […]

Oracle VM VirtualBox Tutorial: Connecting Applications from your Desktop to a database on VirtualBox

If you have your Oracle VM VirtualBox setup and running there is a possibility that you may need to setup the network for the Virtual Machine to make it accessible from the host machine (Desktop or Laptop). This may be needed when you want to connect your local applications to the database running on the VM VirtualBox.

Internet Access with VirtualBox & Host-only Networks (on OS X Mavericks)


When creating VMs on my laptop I like to configure the minimum number network interfaces. I also tend to end up with environments where I want multiple VMs to be able to see each other, see the internet and see my physical host. It seems many people using VirtualBox use the approach of having a “Host-only Adapter” interface and a “NAT” interface. The only reason I have for not liking this is that it (more...)

VritualBox 4.30 on OS X 10.9 Mavericks

I’ve been using OS X for a very long time, and one of the Applications that is invaluable in my day to day work is VirtualBox. It’s a great application allowing you to work with various Oracle versions and products, and I have quite a few linux VMs with differing (more...)

Playing with VirtualBox, Oracle 12c ( and OEL 6.4 – Part 2

We will complete our lab by installing the Oracle Database software, create a Pluggable database and take a look in the Oracle Enterprise Manager Database Express. The steps to install and create an Oracle Database 12c are: 1 – Go

Playing with VirtualBox, Oracle 12c ( and OEL 6.4 – Part 1

Now that 12c was released it’s time to install in on OEL 6.4 64 bits OS. Let’s start playing with this. Before we start with the creation of the VM we will need to download some software first, such as:

Extending the PeopleSoft 9.2 virtual machine with GUI and Guest Additions

In my previous post I described the steps for getting started with the PeopleSoft 9.2 virtual machine. Although I am still thrilled that Oracle has made this generally available, I am of the opinion that it would have even been
