Hello to all

I have created a physical standby database ,I want make backup of it by rman and when I lose it's datafile I can restore it ,making backup and restore is fine but in recovery I encounter some problem
scenarios is follow

1- In rman I create a backup of standby database by this command:
backup database plus archivelog delete all input;

2- I run this comman in rman for recover standby database
run{
2> set until scn 1392701;
3> restore database;
4> recover database;
5> }
(1392701 is extracted from this query "SELECT MAX(NEXT_CHANGE#)+1 UNTIL_SCN FROM V$LOG_HISTORY LH,
V$DATABASE DB WHERE LH.RESETLOGS_CHANGE#=DB.RESETLOGS_CHANGE# AND LH.RESETLOGS_TIME =
DB.RESETLOGS_TIME;" "http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/rman.htm")

but RMAN result is like this:
executing command: SET until clause

4- if I run
run{
restore database;
recover database;
}

I will recieve that error of step 2 (RMAN-06054: media recovery requesting unknown log: thread 1
seq 118 lowscn 1392700)

5- if I just restore the database and I don't perform recovery by rman and I restart redo apply all thing seem fine
but in opening database I'll recieve ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/u01/app/oracle/oradata/sari/system01.dbf' error)

do you know what is problem

thanks
