script not working from crontab, executes individual

Hi,
This script is working successfully when i executed from shell prompt, but the same script scheduled in crontab its not deleting the files,

#! /bin/bash
DAY_1=`(date --date='4 months ago' '+%Y-%m')`
log=/tmp/cleant
adir=/u01/app/oracle/admin/talon/adump
udir=/u01/app/oracle/admin/talon/udump
bdir=/u01/app/oracle/admin/talon/bdump
export DAY_1
echo "Cleaning trace files start " > $log
date >>$log
echo $DAY_1 >>$log
cd $adir
ls -l | grep -i $DAY_1 | awk '{ print $8}'| xargs rm -f
cd $udir
ls -l |grep -i $DAY_1 | awk '{print $8}'| xargs rm -f
cd $bdir
ls -l |grep -i $DAY_1 | awk '{print $8}'| xargs rm -f
cd
echo "Finished " >>$log

i am trying to remove files 4 months ago which would be in huge number(500000 approx. files). if run
$ . remtrc ( it successfully removes files)
crontab (example)
10 00 1 * * * /home/oracle/remtrc > /tmp/cleantrc.log
but from crontab it not able to remove files.
what i am missing in the script.

NAME
bcrontab - Manage users crontab files SYNOPSIS
bcrontab [ -u user ] file bcrontab [ -u user ] { -l | -r | -e } DESCRIPTION
bcrontab interfaces with the bcron-spool daemon to manage crontab files in the privileged spool directory. OPTIONS
-u user Tell bcron-spool that we are acting on behalf of the named user. bcron-spool will only accept the username if bcrontab is running as either root or the same user ID as the named user. -l List the cronab crontab to standard output. -r Remove the user's crontab. -e Edit the current crontab. ENVIRONMENT
VISUAL If this is set, it is used as the editor to invoke to edit a crontab. EDITOR If $VISUAL is not set and this is, it is used as the editor to invoke to edit a crontab. If neither are set, /bin/vi is used. BCRON_SOCKET The path to the named socket used to communicate with bcron-spool. Defaults to /var/run/bcron-spool. LOGNAME USER These two variables are used, in order, to determine the user name invoking the program. One must be set if the -u option is not used. FILES
bcrontab tries to writes a temporary file into the current directory, and then into /tmp if that fails, in order to edit the current crontab. SEE ALSO
