23:58
https://dbagenesis.com/p/oracle-advanced-rman-backup-recovery RMAN has the ability to duplicate, or clone, a database from a backup or from an active database. It is possible to create a duplicate database on a remote server with the same file structure, a remote server will a different file structure or the local server with a different file structure. Cloning the database on the remote host requires two servers. Both servers should have Oracle Software installed on them.

Oracle Tablespace PITR Recovery Lab Activity | TS-PITR Part - 2
 
12:24
https://dbagenesis.com/p/oracle-advanced-rman-backup-recovery Recovery Manager (RMAN) automatic TSPITR enables you to quickly recover one or more tablespaces in a database to an earlier time without affecting the rest of the tablespaces and objects in the database. RMAN TSPITR is most useful for the following situations: 1. You want to recover a logical database to a point different from the rest of the physical database, when multiple logical databases exist in separate tablespaces of one physical database. For example, you maintain logical databases in the orders and personnel tablespaces. An incorrect batch job or DML statement corrupts the data in only one of the tablespaces. 2. You want to recover data lost after DDL operations that change the structure of tables. You cannot use Flashback Table to rewind a table to before the point of a structural change such as a truncate table operation. 3. You want to recover a table after it has been dropped with the PURGE option. 4. You want to recover from the logical corruption of a table. You can also use Flashback Database to rewind data, but you must rewind the entire database rather than just a subset. Also, unlike TSPITR, the Flashback Database feature necessitates the overhead of maintaining flashback logs. The point in time to which you can flash back the database is more limited than the TSPITR window, which extends back to your earliest recoverable backup.

How Oracle Instance Recovery Works
 
09:11
https://dbagenesis.com/ DBA Genesis provides all you need to build and manage effective Oracle technology learning. We designed DBA Genesis as a simple to use yet powerful online Oracle learning system for students. Each of our courses is taught by an expert instructor, and every course is available on demand. Oracle instance recovery is an advanced concept, but its interesting to know and understand it. Oracle performs instance recovery when the database is restarted due to instance failure or shutdown the database with ABORT option(shutdown abort) or startup the database with FORCE option(startup force). Instance recovery is taken care by SMON oracle background process automatically. Instance recovery consists of two steps. One is Roll forward, next is Roll backward.
