When failures occur, the fail over process moves processing performed by the failed component to the backup component. This process remasters systemwide resources, recovers partial or failed transactions, and restores the system to normal, preferably within a matter of microseconds. The more transparent that fail over is to users, the higher the availability of the system. Oracle has a number of products and features that provide high availability in cases of unplanned downtime or planned downtime. These include Fast-Start Fault Recovery, Real Application Clusters, Recovery Manager (RMAN), backup and recovery solutions, Oracle Flashback, partitioning, Oracle Data Guard, LogMiner, multiplexed redo. | ORACLG Oracle Enterprise Manager Oracle Database and Database-Related Metric Reference Manual 10g Release 2 B25986-01 January 2006 Oracle Enterprise Manager Oracle Database and Database-Related Metric Reference Manual 10g Release 2 B25986-01 Copyright 2006 Oracle.
