Welcome to the forum. Please read our OraFAQ Forum Guide and PLEASE read How to use [code] tags and make your code easier to read

If you can't work this out for yourself, you can test it, and see what RMAN says. Like this:

RMAN> restore database until time 'sysdate - 5 ';

So do a test run, that will simply tell you if it is possible:

RMAN> restore database until time 'sysdate - 5 ' validate;

Starting restore at 11-JUL-13
using channel ORA_DISK_1

channel ORA_DISK_1: starting validation of datafile backup set
channel ORA_DISK_1: reading from backup piece C:\TMP\02OCJ40G_1_1.BSET
channel ORA_DISK_1: ORA-19870: error while restoring backup piece C:\TMP\02OCJ40G_1_1.BSET
ORA-19505: failed to identify file "C:\TMP\02OCJ40G_1_1.BSET"
ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 2) The system cannot find the file specified.

failover to previous backup

datafile 5 will be created automatically during restore operation
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

this sort of thing is all in the docs, you know.
