To
perform incomplete recovery,
use the SET UNTIL command to specify the time,

Alternatively, specify the UNTIL clause on the RESTORE and RECOVER
commands.
3. Restore the necessary files with the RESTORE command.
4. Recover the datafiles with the RECOVER command.

channels (connections to server sessions on the target database) perform all RMAN
tasks. By default, RMAN allocates one disk channel for all operations.
The following command configures RMAN to write disk backups to the
/backup
directory
(refer to "Backing Up Database Files and Archived Logs with RMAN").:
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT
'/backup/ora_df%t_s%s_s%p';
The format specifier
%t
is replaced with a four byte time stamp,
%s
with the backup set
number, and %p with the backup piece number.
You
can also configure an Automatic Storage Management disk group as your destination, as
in the following example:
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '+dgroup1';
