Best Practice to enable Flash back logging.

Some of the prep work on looking at the Shared pool parameters is to avoid getting ora-04031 while enabling flashback on
this 1st section gives what needs to be done followed by what things need to be considered such as the storage allocation, retention, etc.,
last section will give you info on what to do if you hit ora-04031
