In my previous blog post on Running ORDS Against the Autonomous Database - Part 2, we had looked at how to add an existing Let's Encrypt (LE) SSL certificate to an Oracle Cloud Infrastructure (OCI) Load Balancer. You'd typically wwant to host your websites or Oracle Application Express applications over a secure transport layer, especially when sensitive data is communicated between the browser and server.
As Uncle Ben would say, "Remember, with great power, comes great responsibility." With the release of Oracle REST Data Services (ORDS) version 19.4.6, many of us were eager to deploy a customer-managed ORDS solution in order to support vanity URLs with Oracle Application Express (APEX), myself included. It has worked well for me until a few days ago, I noticed that my Oracle JET charts weren't loading any more.
In my previous post, we looked at installing and configuring Oracle REST Data Services (ORDS) and have it work with Oracle Application Express (APEX) that comes preinstalled with every Oracle Autonomous Database (ADB). Like APEX, ORDS is also included as a feature of the ADB. However, there are certain situations where you might like to manage your own instance of ORDS.
The Oracle Autonomous Database (ADB) is Oracle's current flagship database product and rightly so! Each instance comes with self-tuning, self-patching and several Oracle Database Options that customer would otherwise have to purchase separate licenses for. Database developers will also be pleased to know that there are a suite of tools at your disposal including Oracle Application Express (APEX), Oracle REST Data Services (ORDS) and Oracle Machine Learning Notebooks.
The minimum instance you can create will have 1 CPU and 1 TB of storage and with so much features, doesn't come cheap. Here's the good news though, Oracle provides everyone two Always Free ADBs through the Oracle Cloud Free Tier offering. Yes, that's a great deal for anyone wanting to host a simple web application on the Internet. It is however, not without limits.
My personal journey with programming started more than two decades ago. Back then, the one language that I was very passionate and determined to master was Java. Early in my career, I would find any opportunity to attend a Sun Microsystems event like the Sun Tech Days, where I had the opportunity to learn about the constantly evolving platform that went from desktop, to enterprise and then on mobile devices. I can still remember watching the cool things you could do with Lego Mindstorms and an embedded Java runtime, and the vision that JXTA was going to revolutionise the Internet of Things with its state-of-the-art, peer-to-peer technology.
