I created a file in /u01/oradata directory as cronjb.ksh which contains following script

30 12 * * * /export/home/oracle/u01/oradata/rman.ksh

'/export/home/oracle' is my root directory. I then moved cronjb.ksh file to my '/export/home/oracle' directory. i typed crontab cronjb.ksh. However my cronjob named cronjb.ksh does not run. I typed mail and i dont see any email. Below is my rman.ksh script. is there any command to findout why my cronjob not working?

[b]exec>/u01/oradata/bkup_$$.log 2>&1
ORACLE_HOME=/u01/app/oracle/product/10.2; export ORACLE_HOME
ORACLE_SID=SEED; export ORACLE_SID
PATH="$PATH:$ORACLE_HOME/bin"
rman target=/<<

there is no need to double post your question. This thread should be deleted.
