I'm having this scenario which for the moment I cannot resolve.
I wrote a script to make a dump/export of the oracle database. and then put this entry on crontab to be executed daily for example.
The script is like below:
Code:
cat /home/oracle/scripts/db_backup.sh
#!/bin/ksh
#Backup export database script
#Created 05-04-2011
# * * *
DATE=`date +%d%m%Y-%H%M%S`
ARCHIVE_DIR=/home/oracle/arch
SCRIPTS_DIR=/home/oracle/scripts
USER=oracle
PASS=XXXXXXXX
(
echo "Starting database dump ..."
date
cd $ARCHIVE_DIR
exp $USER/$PASS FILE=filename_$DATE.dmp log=logfile_$DATE.log
echo "End of database dump ..."
date
) | tee $ARCHIVE_DIR/exp_logfile-$DATE.log 2>&1
The crontab entry and also the script is executed as oracle user. When I execute directly from the shell the script is executed correctly and the dump is also generated ok.
But on the cron job I get only the log part "Starting/Stoping database dump ..." and not the export dump file and dump_log file: the "exp..." part.

KEP_RELOAD(1) General Commands Manual KEP_RELOAD(1)NAME
kep_reload - Update Predict's Keplerian elements
SYNOPSIS
kep_reload
DESCRIPTION
KEP_RELOAD is a simple utility that forces an immediate reload of PREDICT's Keplerian database through a socket connection while PREDICT is
running in server mode. It is especially useful in environments where PREDICT runs continuously, and periodic Keplerian element updates
are made outside of PREDICT, such as through scripts run through a crontab.
The "kepupdate" script found in this directory is an example of a Keplerian element update script that can be run on an automated basis
through a crontab. It is designed to be placed in your home directory under a subdirectory called "cronjobs". It downloads Keplerian
orbital data from www.celestrak.com using the HTTP protocol. (The "wget" utility, available from the Free Software Foundation, is
required, and is included in many Linux distrubutions.)
Type crontab -e to edit your crontab. Simply add the following entry:
0 8 * * * kepupdate
and your orbital database will update each morning at 8:00 AM (provided you have a network connection at that time).
See the crontab man page for more information on editing your crontab.
