Files in Support of Backup and Recovery Operations
An Oracle database consists of three types of mandatory files: control files, online redo logs, and data files. This chapter looks at the basics of managing these critical files. This chapter also discusses how to implement archiving (which generates archive redo log files) and enabling a fast recovery area (FRA). Understanding how to enable archiving and how to manage archive redo logs is a crucial part of database administration and backup and recovery. It’s also important to understand basic FRA concepts as RMAN (unless otherwise directed) will by default write backup files to the FRA.
