Configuring RMAN
Oracle Recovery Manager (RMAN) is Oracle's flagship B&R tool. RMAN is provided by default when you install the
Oracle software (for both the Standard Edition and Enterprise Edition). RMAN offers a robust and flexible set of B&R
features. The following list highlights some of the most salient qualities:
•
Easy-to-use commands for backup, restore, and recovery.
•
Ability to track which files have been backed up and where to. Manages the deletion
of obsolete backups and archive redo logs.
•
Parallelization: Can use multiple processes for backup, restore, and recovery.
•
Incremental backups that only back up changes since the previous backup.
•
Recovery at the database, tablespace, data file, table, or block level.
•
Advanced compression and encryption features.
•
Integration with media managers for tape backups.
•
Backup validation and testing.
•
Cross-platform data conversion.
•
Data Recovery Advisor, which assists with diagnosing failures and proposing solutions.
•
Ability to detect corrupt blocks in data files.
•
Advanced reporting capabilities from the RMAN command line.
The goal of this chapter is to present enough information about RMAN that you can make reasonable decisions
about how to implement a solid backup strategy. The basic RMAN components are described first, after which you
walk through many of the decision points involved in implementing RMAN.

The RMAN-related chapters in this topic aren't intended to be a complete reference on all aspects of B&R.
That would take an entire book. These chapters contain the basic information you need to successfully use RMAN for
B&R. If you require advanced RMAN information regarding backup, restore, and recovery, see
