Delete archive logs from the standby server

I implemented the following script to delete archive logs from a standby server.
You cannot just delete the archive log files because that will leave entries in the V$ARCHIVED_LOG table.

#!/bin/ksh
#**************************************************************
# Here is where we loop through each SID in /etc/oratab . . .
#**************************************************************
cat /etc/oratab grep '^c.*:.*:[Yy]$' {
while IFS=":" read ORACLE_SID ORACLE_HOME junk
do
PATH=${ORACLE_HOME}/bin:$PATH
export ORACLE_SID ORACLE_HOME PATH

# Now run the SQL script to generate a rm script
sqlplus -s /nolog <<EOF
connect / as sysdba
set heading off feedback off timing off
spool /usr/users/oracle/cronscripts/logs/rm_arch_${ORACLE_SID}.ksh
select 'rm '||NAME from v\$archived_log 
where REGISTRAR='RFS' 
and APPLIED='YES' 
and DELETED='NO' 
and COMPLETION_TIME < (SYSDATE-1);
spool off
exit
EOF


# Now run the generated rm script
chmod 740 /usr/users/oracle/cronscripts/logs/rm_arch_${ORACLE_SID}.ksh
/usr/users/oracle/cronscripts/logs/rm_arch_${ORACLE_SID}.ksh

# Now use RMAN to update V$ARCHIVED_LOG.DELETED
rman <<EOF
connect target /
crosscheck archivelog all;
delete noprompt expired archivelog all;
EOF

done
}

Notes:
columns V$ARCHIVED_LOG.REGISTRAR and APPLIED
If REGISTRAR='RFS' and APPLIEDis NO, then the log has arrived at the standby but has not yet been applied.
If REGISTRAR='RFS' and APPLIED is YES, the log has arrived and been applied at the standby database.

column V$ARCHIVED_LOG.DELETED
Indicates whether an RMAN DELETE command has physically deleted the archived log file from disk (YES) or not (NO)

RMAN EXPIRED
Removes only files whose status in the repository is EXPIRED.
RMAN marks backups and copies as expired when you run a CROSSCHECK command and the files are absent or inaccessible.
To determine which files are expired, run a LIST EXPIRED command.

RMAN NOPROMPT
Beginning in Oracle9i, RMAN's default behavior is to prompt for confirmation when you run DELETE EXPIRED.
In prior releases, RMAN did not prompt.
