About this blog and test environment

As of October 2021

• My test environments are:
  • Always Free ATP 19c (now at 19.13.0.1, but with undocumented Cloud-only enhancements…)
  • Always Free ATP 21c (now at 21.2.0.0)
  • Database App Development VM with Oracle 19c (19.3)
• I refer to the 19c or 21c documentation depending on the subject.

As of October 2018

• My test environment is Virtualbox 5.2.20 running the Database App Development VM with Oracle 18c (18.0.0.0.0) on a MacBook Pro (15.4/2.0GHZ/8GB/256GB FLASH)
• My development tool is Oracle SQL Developer (version 18.3).
• This blog uses the Able theme because it is wide: I try to avoid horizontal scrolling.
• The photo shows sunset over Capri, Italy in late December 2013.
• I use American spelling (unless I forget).
• I wrote a function to generate an html table from an SQL query. I’ll blog about that when it’s mature.
• Starting in 2018, I refer to the Oracle 18c documentation unless otherwise stated.
