High Availability Architecture for Oracle REST and APEX


This guide includes step-by-step instructions to install and configure the Apache HTTPD, Tomcat, Oracle REST Data Services, and Oracle Application Express (APEX) technology stack within a simple, highly available infrastructure.

Database Independence is a Myth


One thing that going over this material again and again over the last few weeks has driven home for me, especially as our customer considers how best to implement their various choices for development frameworks, is just how much of a fairy tale the promises of middle-tier application servers turned out out to be in terms of processing business logic.

Automatically Protecting PII Data Columns with Transparent Data Encryption

APEX Patches and NLS_LENGTH_SEMANTICS


I'm going to post this as a reminder to myself as much as anything else.

The Frustrated DBA


While perusing recent postings on the Ask Tom web site, I chanced across this one, entitled "Frustrated DBA", in which John asks the following question: "Is it just me or does doing the "typical DBA" tasks like installing, patching, backing up, checking backups, monitoring databases, creating users, checking space and other mundane tasks get boring … Continue reading The Frustrated DBA

How to Load Large WebSheets into APEX


A few years ago I started keeping most of my system documentation in APEX websheets. It's great for keeping things organized and readily available no matter how I'm accessing my work network (on-site, VPN, etc.). A lot of my installation documents have embedded screenshots, and the png files are attached to the websheet as annotations. … Continue reading How to Load Large WebSheets into APEX

In my last post I talked about the legal rules of the road in regards to designing and implementing a database information system, starting from the top level and driving down to the nitty gritty step-by-step hardening instructions, including the STIG. Once the applicable rules are understood, it is important … Continue reading Passing the Test

The Rules of the Road


What needs to be done? Before a driver heads out on the road, it is important for him or her to know the rules. Not just common sense stuff like "don't drive on the wrong side of the road", but the actual rules and laws that govern what you're about to do, like obeying a … Continue reading The Rules of the Road

And Now for Something Completely Different…


It's a new year, and therefore time to start a new series of posts. This year I will be looking at how to secure Oracle on a limited budget (or more commonly a non-existant one), with an emphasis on what can be done for little or no additional cost beyond the basic hardware and software … Continue reading And Now for Something Completely Different…
