Configuring RMAN
As stated earlier in the topic, 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.
Understanding RMAN
RMAN consists of many different components. Figure 4-1 shows the interactions of the main RMAN pieces. Refer back
to this diagram when reading through this section.
