Performing a Point-in-Time Restore of the Entire Database
This section resembles the previous example with the exception that you must restore all data files, then perform a point-in-time restore of the entire database.

RMAN> host 'rm /ora1/app/oracle/oradata/orcl/*dbf';
host command complete
RMAN> host 'ls -ltr /ora1/app/oracle/oradata/orcl/*dbf';
ls: /ora1/app/oracle/oradata/orcl/*dbf: No such file or directory
At this point, all data files are deleted to simulate the problem. Perform a Quick Restore of the latest backup so that the paths cataloged in RMAN become valid and accessible.

In this example, recover the database up to the point-in-time when the last backup was performed. There is only one archive log that is necessary to recover from this backup. Find the target SCN number by entering the following:
alter system dump logfile '/tmp/bexoracle_orcl_1224864495/akash/LOGS/1_30_668010235.dbf';
Then check the Next scn value in the header of the dumped file. In this example, the value is 3806925.
