RMAN (Recovery Manager) is a backup and recovery manager supplied for Oracle databases (from version 8) created by the Oracle Corporation. [1] It provides database backup , restore, and recovery capabilities addressing high availability and disaster recovery concerns.
The advantage to this is the quicker recovery time, requiring only a full backup and the last differential backup to restore the system. The disadvantage is that for each day elapsed since the last full backup, more data needs to be backed up, especially if a significant proportion of the data has changed.
In computer science, Algorithms for Recovery and Isolation Exploiting Semantics, or ARIES, is a recovery algorithm designed to work with a no-force, steal database approach; it is used by IBM Db2, Microsoft SQL Server and many other database systems. [1] IBM Fellow Chandrasekaran Mohan is the primary inventor of the ARIES family of algorithms. [2]
Modern hard drives feature an ability to recover from some read/write errors by internally remapping sectors and performing other forms of self-test and recovery. The process for this can sometimes take several seconds or (under heavy usage) minutes, during which time the drive is unresponsive.
Usually, there are four phases when it comes to successful data recovery, though that can vary depending on the type of data corruption and recovery required. [20] Phase 1 Repair the hard disk drive The hard drive is repaired in order to get it running in some form, or at least in a state suitable for reading the data from it.
At that time, most systems were batch-oriented mainframes. An offsite mainframe could be loaded from backup tapes pending recovery of the primary site; downtime was relatively less critical. The disaster recovery industry [18] [19] developed to provide backup computer centers. Sungard Availability Services was one of the earliest such centers ...
In telecommunications, a recovery procedure is a process that attempts to bring a system back to a normal operating state. Examples: Examples: The actions necessary to restore an automated information system 's data files and computational capability after a system failure.
Database activity monitoring (DAM, a.k.a. Enterprise database auditing and Real-time protection [1]) is a database security technology for monitoring and analyzing database activity. DAM may combine data from network-based monitoring and native audit information to provide a comprehensive picture of database activity.
