As the licensing of the Oracle Flashback Features has changed over recent releases I wanted to provide a summary. In 12c Oracle has opened up basic usage of Flashback Data Archive which is a handy way to add data archiving capabilities to existing/legacy applications.
The cost part of Flashback Data Archive is now an Optimization feature which reportedly will reduce the disk space requirements by 2-4 times. This requires an Advanced Compression license to use.
