When Oracle Database 18c Express Edition (18cXE) was released late last year, I was motivated to work on an image for running the newly released, FREE database using Docker. The scripts were based on the official Docker images published by Oracle. With much help from Martin D'Souza, we released the scripts to the community with pointers on how to install and run an Oracle Application Express (APEX) stack.

USS Chafee (DDG-90)

Late last year, I started binge watching the entire four seasons of The Last Ship. It was one of the rare TV serials that my wife and I shared a common interest in. I think this was mostly because the first season was centered around the ship and its crew's fight against total human annihilation by an infectious disease. For me though, it was also about the military hardware and camaraderie amongst the soldiers.

I have written on two occasions, "Just a Drop of Oracle APEX" and "APEX and the Affordable Cloud!", about how easy it is to get up and running on hosting providers like Linode and DigitalOcean. The approach largely involves Vagrant, and though it is an easy to use tool, it still needed a little bit of DevOps heroism, and sometimes, dealing with API keys may not necessarily be a priority for someone looking for a quick way to setup a consistent and robust Oracle Application Express environment.

Updated November 18, 2018 Added a help utility to populate an Oracle Wallet with root certificates

Oracle Database 18c Express Edition comes with a usable Oracle Wallet. In a previous article, I had described how to:

  1. Obtain the certificates necessary to make a successful SSL/TLS connection.
  2. Create and add these certificates to the Oracle Wallet.
  3. Configure the APEX instance to use the wallet.

Someone had asked in the comments, what certificates were necessary for Social Sign-in in Oracle Application Express (APEX) to work. It's something that I think most of us would like to know too, so I did a little more digging and here's what I found for three of the more popular social platforms: Google, Facebook and Microsoft.

1280 720 APEX and ORE in Action

I wrote, quite a while ago, on how Oracle Application Express (APEX) developers could integrate R functionality/code in their applications. This was done primarily through Node.js packages and exposed as RESTful Web Services. Not the ideal solution, but useful for people wanting to integrate R statistical calculations and complex charting, but could not afford the hefty price tag for an Oracle Database Enterprice Edition license, plus the Oracle Advanced Analytics database option.

The revolutionary 18c release of the Oracle Database Express Edition (XE) significantly changed the Data Analytics playing field. The no-cost platform has resource caps (2 CPU, 2 GB RAM and 12 GB data storage). It's not going to help perform complex GWAS (Genome-wide Association Study), but should suffice for many smaller research projects, statistical reporting and creating useful prediction models.

Unfortunately, the XE website has only a single line that says anything about this cool feature of the database:

If you prefer R programming, Oracle Database supports that too.

How do we get started?
