Datapump backup when scheduled through crontab doesnt work!

Question

Hi Masters,
I had a script for taking export backup. I modified to take datapump backup instead of the conventinal export. And since then the cron job has stopped running.
The oriiginal script was:
#!/bin/bash
cd /opt/ora10gr2
. .profile
cd /backup/oracle10g/EBACKUP/scripts/daily_run/
kdat=`date +%d`
kmon=`date +%b`
while read i
do
touch /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
echo 'start time ' $i >> /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
date >> /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
exp system/manager@$i file='/backup/oracle10g/EBACKUP/db/daily_backup/dumps/'$i\_$kdat\_$kmon'.dmp' log=/backup/oracle10g/EBACKUP/db/daily_backup/logs/$i\_$kdat\_$kmon'.log' direct=y owner=sysadm statistics=none
echo 'backup successfully done for ' $i >> /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
echo 'end time ' $i >> /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
compress '/backup/oracle10g/EBACKUP/db/daily_backup/dumps/'$i\_$kdat\_$kmon'.dmp'
date >> /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
done < /backup/oracle10g/EBACKUP/scripts/daily_run/list_DB
The names of the databases were kept in a file list_DB.
After modification, the script looked like:
#!/bin/ksh
cd /opt/ora10gr2
. .profile
cd /backup/oracle10g/EBACKUP/scripts/daily_run/
kdat=`date +%d`
kmon=`date +%b`
while read i
do
touch /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
echo 'start time ' $i >> /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
date >> /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
expdp system/manager@$i DUMPFILE=$i\_$kdat\_$kmon'.dmp' LOGFILE=$i\_$kdat\_$kmon'.log' SCHEMAS=sysadm DIRECTORY=dumps JOB_NAME=daily_backup PARALLEL=4
echo 'backup successfully done for ' $i >> /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
echo 'end time ' $i >> /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
gzip '/backup/oracle10g/EBACKUP/db/daily_backup/'$i\_$kdat\_$kmon'.dmp'
date >> /backup/oracle10g/EBACKUP/db/daily_backup/logs/exp_log\_$kdat\_$kmon.log
done < /backup/oracle10g/EBACKUP/scripts/daily_run/list_DB
This modified scripts run when executed stand alone from command line. But doesnt run when executed through crontab.
Any help will be highly appreciated.
Thanks,
Anoop

Hi,
Two things I want to tell U.
1. Re-direct the CRON output to log file & check the logfile for ERRORS.
example :-
43 17 * * 1-4 /backup/oracle10g/EBACKUP/scripts/daily_run/exp_bkpdb_temp1.sh > /backup/oracle10g/EBACKUP/scripts/daily_run/cron_expdb.log
2. In command-line U have all the necessary PATH's set, hence it got executed. But when u execute the same script through CRON u have to manually set the PATH's in ur script.
Do the below in command line:-
echo $PATH
add the output of above command in ur script as below & try.
#!/bin/ksh
export PATH=<output here....>
