Help with House keeping Archivelog files....!!

Question

Hi,
I am trying to develop a script for housekeeping archive log files. The archives are written to a local disk, then moved to a different location, before being backed up to a tape. The purpose of the script is to identify and move the archive logs to a different location.
Following is the code for the script:
ORACLE_SID=BSCSDEV1
ORACLE_BASE=/oracle/app/oracle
ORACLE_HOME=/oracle/app/oracle/product/10.1.0/db_1
PATH=$ORACLE_BASE:$ORACLE_HOME:$PATH
ARCHDIR1=/oracle/oradata/BSCSDEV1/arch1
ARCHDIR2=/oracle/oradata/BSCSDEV1/arch2
rm -f archout.txt
export ORACLE_SID ORACLE_BASE ORACLE_HOME PATH
$ORACLE_HOME/bin/sqlplus -S '/ as sysdba'<<END
@archquery.sql
exit
END
while read line
do
dir=`dirname $line`
file=`basename $line`
if [ $dir = $ARCHDIR1 ]; then
if [ -f $line ]; then
echo "$file : matched"
mv $line $HOME/movedfiles/$file
fi
elif [ $dir = $ARCHDIR2 ]; then
if [ -f $line ]; then
echo "$file : matched"
mv $line $HOME/movedfiles/$file
fi
else
echo "No Files to Move......"
fi
done < $HOME/archout.txt
ARCHQUERY.SQL:
set linesize 75
set verify on
set feedback off
set heading on
set termout off
set serveroutput on
set pagesize 999
spool archout.txt
select name,completion_time
from v$archived_log
where to_char(completion_time,'DD-MON-YY HH24:MI')<=(select to_char(sysdate - (30/1440),'DD-MON-YY HH24:MI') from dual)
and
to_char(completion_time,'DD-MON-YY HH24:MI')<=(select to_char(sysdate,'DD-MON-YY HH24:MI') from dual)
and
to_char(completion_time,'DD-MON')=(select to_char(sysdate,'DD-MON') from dual)
and
archived='YES';
spool off
My Logic:
I am trying to identify the archive files generated every 30 minutes from v$archived_logs. For this, I am using the COMPLETED_TIME column and am comparing the same with SYSDATE.
These files, I am comparing with the files in the archive destination and then am moving them to a different location.
My problem:
When I test the query, it lists out even those outside the timerange. Also, files that are shown as completed in the ARCHIVED columns and are physically present are not identified for at least 45 minutes.
Could one of you please go through the scripts and tell me where I am going wrong?
Any tips in this regard is deeply appreciated.
Thanking You all in advance,
Sriraman.

Hi,
Thanks for your reply.
In my production setup, the client's techspecs insist on setting up only 1 archival destination. I did suggest the usage of a second destination, but they do not want it. They did not give me any concrete reason for this. So I have no option but to do this.
It is therefore necessary that we move only those archive files that have been completed and not files being currently used.
That is the reason for this script.
Could you please have a look at it and tell me if I am missing something here?
Regards,
Sriraman
