In addition to database backup and recovery, RMAN can also detect potential data corruptions. In this video, learn how to use the VALIDATE DATABASE CHECK LOGICAL command to detect potential data corruptions in your database and VALIDATE BACKUPSET to make sure your backups are intact.
- [Instructor] In addition to using RMAN…for database backup and recovery…and backup management,…RMAN can also check your database and detect…any corruptions in your data.…Either logical corruptions which can occur…if due to a software bug in the Oracle software,…Oracle requested the disc to write…an incorrect block of data,…or due to a physical corruption which can occur…if Oracle requested the disc to write a valid block…but due to a disc subsystem error,…either the disc controller or…the disc itself caused a bad data block to be written.…
It's very to easy to request RMAN…to scan, validate and check the state…of your database and detect any potential…logical or physical block corruptions…which can lead to data loss.…Detecting these corruptions early is very important.…So let's see this capability in action.…We'll start by opening RMAN and connecting…to our target database.…So I'll type RMAN target equals backslash…and then via a single command,…validate data base…check logical,…I will request RMAN to scan my database…
