Rman

From Wikipedia, the free encyclopedia

The article discusses the Oracle database utility program rman. For the Unix-level reverse man-page compiler, see rman (Unix)

The rman backup and recovery manager supplied for Oracle databases by Oracle Corporation provides database backup, restoration and recovery capabilities, addressing high-availability and disaster-recovery concerns. Oracle Corporation recommends rman as its preferred method for backup and recovery, and has written command-line and graphical (via Oracle Enterprise Manager) interfaces for the product.

[edit] Implementation

The designers of rman aimed at integration with Oracle database servers^{[citation needed]}, providing block-level corruption-detection during backup and restore.^{[citation needed]} rman optimizes performance and space-consumption during backup with file-multiplexing and backup-set compression; it integrates with Oracle Secure Backup (OSB) and with third-party media-management products for tape backup.

A syntax-system of many commands and options allows database administrators to fine-tune the methods and performance of backups and restores of Oracle data and Oracle configuration-information.^[1]

"Complete recovery" entails restoring all available consistent information to the most current point in time.^[2]

"Incomplete recovery" options allow specifying restoration to a given point of time in the past.
