VirtualBox 5.2.2

VirtualBox 5.2.2 has been released.

The downloads and changelog are in the usual places.

I’ve done the installation on my Windows 7 PC at work, macOS High Sierra and Oracle Linux 7 and all worked fine.

For some reason the automatic download of the extension pack failed on all platforms. I just downloaded it manually and installed it and it was OK.

I was hoping this would solve the problem I have with (more...)

Installing Minikube and Kubernetes on Windows 10

Quick notes on the installaton of Minikube for trying out Kubernetes on my Windows 10 laptop (using VirtualBox –not Hyper-V)

Create Debian VM with Docker Host using Vagrant–automatically include Guest Additions

A short and simple article. I needed a Debian VM that I could use as Docker host – to run on my Windows 10 laptop. I resorted to Vagrant. With a few very simple steps, I got what I wanted:

0. install Vagrant (if not already done)

0. install Vagrant plugin for automatically adding Virtual Box Guest Additions to every VM stamped out by Vagrant (so folder mapping from host laptop to VM is supported)

Quickly create a Virtualbox development VM with XE DB using Kickstart, Packer, Vagrant

The topic of quickly creating an Oracle development VM is not new. Several years ago Edwin Biemond and Lucas Jellema have written several blogs about this and have given presentations about the topics at various conferences. You can also download ready made Virtualbox images from Oracle here and specifically for SOA Suite here.

Over the years I have created a lot (probably 100+) of virtual machines manually. For SOA Suite, the process of installing the (more...)

Install Oracle’s VirtualBox

If you don’t have the luxury of having a server ready available but you want to do some research and development or training on Oracle, then Oracle’s VirtualBox is a perfect solution.

Prerequisites

To be able to use VirtualBox, you need to disable Hyper-V as it blocks all other Hyper Visors from calling VT hardware.  See my post blog on how to do this:

Disabling Microsoft’s Hyper-V to use Oracle’s VirtualBox

If you want to use Oracle’s VirtualBox on Windows 10, you first need to disable Microsoft’s Hyper-V.  I’ve used VirtualBox many times in the past but on the likes of Windows 7, where Hyper-V isn’t installed by default as part of the O/S.  It seem on Windows 10 Enterprise, Hyper-V is installed by default and is started as part of the bootup.

Hyper-V blocks all other Hyper Visors like VirtualBox from calling VT (more...)

How to automatically build any recent version of the Oracle database.

There are many situations where you want to use a very specific configuration of the Oracle database, for example when a client has an issue and is still on EL5, or gets disk errors on a filesystem that is ext3, or is using ASM and gets weird IO patterns. Other examples are: you want to test the newest PSU to see if responds differently to an issue you are working on, or you want to (more...)

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: https://github.com/oravirt/vagrant-vbox-si-fs https://github.com/oravirt/vagrant-vbox-si-asm 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

jenkins

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...)

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!)

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.
