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...)
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.
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...)
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...)
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.
If you need TranslationHub (Windows only) for your forms and reports development and plan to move to one of the following
- 12c Database for your TranslationHub repository
- 12c Forms/Reports (only available for 64 bit Windows)
- higher version of 64 bit 11g Forms/Reports
then please immediately stop! None of this combination works with TranslationHub!
For the last point I had created enhancement request 14155931 back in June 2012!
For the first point I had created a service request (more...)
This was my second day:
Michael Tamm (optivo GmbH): Feature Toggles on Steroids
Very good summary off all topic’s covering feature toggles. Wish I had this summary 2 years before, were we have evaluated this. Unfortunately furthermore no solutions for declarative frameworks like Oracle ADF with it’s wizards and xml configurations, which later generated code. Ironic answer to my question: “Don’t use frameworks – use Java”
Alexander Casall (Saxonia Systems AG): User Experience for techies
This year I have decided to give the Javaland conference a try. I’m not a java professional, but in the program was listed a lot of interesting testing presentations, so my company booked for me.
The location in Phantasierend Brühl near cologne was very fine. Unfortunately the conference rooms had not enough space this year so for some presentation you have to go to 2 rooms outside of the parc. Additionally it is not understandable, why (more...)
If you try to install oracle forms & reports 18.104.22.168 on SLES 11.3 than despite all installer checks are passed maybe you get a message like:
Error in invoking target ‘install’ of makefile ‘<FR_HOME>/sqlplus/lib/ins_sqlplus.mk’.
The reuirement check of the installer shows only missing openmotif classes which are not really required on SLES (see Doc ID 1567715.1), but no problems with a compiler or something similar.
Checking for binutils-2.19-11. (more...)
