The Oracle Recovery Manager (RMAN) is the recommended backup and recovery tool provided with the Oracle Database Server 10g software. RMAN was first introduced in Oracle 8, and Oracle has steadily made enhancements and improvements with each new release of Oracle to meet the heavy demands required for database backup and recovery.
RMAN has grown to meet the demands of exponentially larger database sizes and more stringent availability requirements. Database servers have grown in size with technology gains of CPU, bus architectures, and more efficient disk subsystems. Disk costs have steadily decreased to more affordable and acceptable levels and have now become an economic alternative to tape storage.
RMAN has been redesigned in Oracle 10g to support these contemporary database environments. RMAN now places more focus on backing up and recovering the changes to the database instead of the complete database. This allows RMAN to support backups of larger databases and recover in faster timeframes.
This chapter discusses configuring and setting up RMAN. Configuring RMAN is the first step in the RMAN process. RMAN must be set up and configured to each environment's requirements. We will walk through this process in detail through examples and demonstrations.
This chapter walks through the parameters for RMAN that are demonstrated in the configuration settings. You will perform the basics of starting RMAN and configuring or setting up RMAN. The remainder of this chapter focuses on more complex topics such as autobackups using the control file.
NOTE
This chapter takes you through a review of the common RMAN features. The review will demonstrate these features with examples. Where applicable, you will walk through the new 10g features and capabilities of RMAN.
The next few chapters discuss topics such as "Using RMAN," "Recovering from Non-critical Losses," "Flashback Database," "Recovering from User Errors," and "Database Corruption."
