Issues with shell script

Question

Hi,
I am executing on procedure using the shell script. The Shell script would the spool the output of the procedure into Status.txt file and send the condents through the mail. I am getting correct output when i run the job manually. But it is not giving the output when the job is scheduled in Crontab. Please find the below my shell script.
ORACLE_SID=ora
export TNS_ADMIN=/oracle/11.2.0/network/admin
export ORACLE_HOME=/oracle/11.2.0
export PATH=/oracle/11.2.0/bin:$PATH
export LIBPATH=/oracle/11.2.0/lib32:$LIBPATH
sqlplus -s test/test@test << EOFSQL
SET HEAD off
SET LINESIZE 8000
SET feedback OFF
SET pagesize 0
SET termout OFF
SET SERVEROUTPUT ON
SPOOL Status.txt
begin JobStatus();
end;
SPOOL off
SET termout ON
exit;
EOFSQL
TO='EmailID'
file=/myFolder/Status.txt
cat $file|mailx -s "Status" ${TO}

The only PATH a user cron job knows by default is "/usr/bin" and "/bin", hence it won't find any Oracle applications. ORACLE provides a tool named "oraenv" to setup the required Oracle shell environment. oraenv reads /etc/oratab to setup $ORACLE_HOME, etc. It is by default installed in /usr/local/bin. The following example should work:
#!/bin/sh
# Filename: /home/oracle/scripts/sqlplus_sample.sh
# Author: dude
PATH=/usr/local/bin:$PATH
export $PATH
ORACLE_SID='orcl'
ORAENV_ASK=NO
. oraenv -s
oradate=`sqlplus -s /nolog <<-EOF
  set pages 0 feed off
  connect / as sysdba
  select sysdate from dual;
exit
EOF
`
echo "`date`: Oracle $oradate" >> /tmp/sqlplus_sample.output
[oracle@vm10]$ chmod 755 /home/oracle/scripts/sqlplus_sample.sh
[oracle@vm10]$ crontab -l
* * * * * /home/oracle/scripts/sqlplus_sample.sh
[oracle@vm10]$ cat /tmp/sqlplus_sample.output

Also, depending on how you connect, you don't need to export TNS_ADMIN. If you establish a local connection you will be connecting to the oracle database process directly using the BEQ protocol, in which case you don't even need a listener process running. For instance:
$ lsnrctl status
