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:

Fix “BEA-000394: Deadlock detected” for Weblogic with ADF Applications 12.2.1.2

If you try the newest version 12.2.1.2 (or maybe earlier versions too) you see, that your managed server does not restart, when

  • you have deployed your ADF application(s)
  • you try to restart the managed server with ADF
  • you use intentionally or not shared libraries in your weblogic-application.xml (see example below)
<?xml version = '1.0' encoding = 'UTF-8'?>
<weblogic-application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

#DOAG2016 wrap up

doag_wegweiser

Another DOAG is over and here are my summary.

Day 1

Unfortunately the early train from duesseldorf arrives not before 9:30, so I missed the first morning slot. But on the other hand I this was the slot where I had to decide between 8 presentations, which I’m interested in.

The first soft skill presentation was about creative techniques beyond brain storming. The mentioned 3 techniques was all unknown for me, maybe I give it (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...)

Set all WebLogic log levels to “Inherit” via WLST

Logging is a very useful feature of WebLogic.

Unfortunately the log levels, which are set after a clean install of WebLogic or some of the Fusion Middleware product creates a lot of noise and therefore it costs I/O performance.

Additional after analyzing an issue with logging often resetting the log level is forgotten.

Here you get a script to reset the log levels at regular intervals or after a trace session.

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 => "add_swap.sh"
...

This calls the script add_swap.sh 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...)

Virtual Development Server: Creating Virtualbox machine including docker containers with Vagrant

As I want to decouple my development server from my computer as much as possible I want to create first a virtual machine with linux.

Because I have used Oracle Virtualbox in the past successfully, I will use it here too.

As I want have later a reproducible environment via Infrastructure as code, I give Vagrant a try for this. As source code management system I use GIT, my remote repository is located at CloudForge.

Virtual Development Server: The idea

For long time I had the idea to create a virtual development server for testing some ideas and play with some new and old technologies.

The several components should be easy replaceable and should influence my computer as little as possible.

So in the next blogs of this series I will discuss several technologies like vagrant, docker, jenkins and several oracle database and development stacks.

Please stay tuned!
