After attending the Norwegian Oracle User Group conference (ougn2019) earlier in the year I was inspired to learn a bit more about Oracle Application Express (APEX).
I have never used Oracle APEX so I thought this would be a good learning opportunity and also provide some great content for some of my presentations later in the year.
Having already written a number of Ansible playbooks, the use of the Ansible provider was a simple choice for the automation of the installation and configuration, but this could have also be achieved using bash scripts etc..
Use of Ansible Roles
From experience, I find good approach is to breakdown the steps into roles for different tasks and OS users before I start scripting, this provides a skeleton which I can flesh out as I test the playbook. For my Oracle APEX VM I defined the following roles:
- Install packages
- Configure OS environment
- Install Oracle xe from downloaded RPM
- Configure environment
- Unzip Apex media
- Install and configure Application Express (APEX)
- Unzip JAVA media
- Unzip Tomcat media
- Configure Apache Tomcat
- Unzip Oracle REST Data Services (ORDS) media
- Configure ORDS
- Install ORDS war file
- Start Apache Tomcat
How did I do ?
My target was to deliver a fully built and configured environment that I could access from my Mac without having to do any post-setup configuration steps.
Ok, lets see if Apache Tomcat home page is accessible with – http://oraclexe:8080/
And the health of Apache Tomcat Server with – http://oraclexe:8080/manager/status
Can we we access the Apache Tomcat Virtual Host Manager – http://oraclexe:8080/host-manager/html
And finally lets check we have installed the Oracle REST Data Services (ORDS) using the Apache Tomcat Application Manager – http://oraclexe:8080/manager/html
That all looks good, what about the APEX Admin console – http://oraclexe:8080/ords/apex_admin
And to finish our Application Express tests how about the APEX login screen – http://oraclexe:8080/ords/apex
And to finish off, lets check that my cx_oracle python library is working OK.

It’s all looking good, so far…
Over my next few Blogs I will share details of the Vagrant build, Ansible playbook and GitHub details for you to build your own environment.
