.sh files

to delete archivlogs, with is older then 1 day: -
find /Oracle/Cron_exp_backup/ntucusr* -mtime +1 -exec rm {} \;

to take a full backup through RMAN: -
rman target sys/orcl@orcl catalog rman/rman@orcl cmdfile=/home/oracle/rman.sql
rman.sql: -
backup database;

How to generate unique logfile through crontab:
30 12 * * * /u01/app/oracle/bin/rman_backup.pl > /u01/app/oracle/log/rman_backup_$(date +\%Y\%m\%d_\%H:\%M:\%S\%z).log > /dev/null 2>&1
If you need only the date (not including the time element):
30 12 * * * /u01/app/oracle/bin/rman_backup.pl > /u01/app/oracle/log/rman_backup_$(date +\%Y\%m\%d).log > /dev/null 2>&1

Oracle backup expdp script (cron job):

#!/bin/bash

#Backup script by Cédric Sougné.
export ORACLE_BASE=/u01/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORACLE_SID=(sid_name)
export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin

ADMIN_EMAIL= » »
LOGFILE=$ORACLE_BASE/admin/$ORACLE_SID/backup_logs/expdp-`date +%d%m%y%H%M%S`.log

EXPORT_PATH=/u01/oracle/export_backup
DMP_FILE= »expdp-`date + »%d%m%Y_%H%M%S »`.dmp »
LOG_FILE= »expdp-`date + »%d%m%Y_%H%M%S »`.log »

echo « Starting … » > $LOGFILE
expdp \’sys/ as sysdba\’ FULL=y DIRECTORY=EXPORT_BACKUP_DIR DUMPFILE=$DMP_FILE LOGFILE=$LOG_FILE
#expdp mrmrs/mrmrs TABLES=resident,sejour DIRECTORY=EXPORT_BACKUP_DIR DUMPFILE=$DMP_FILE LOGFILE=$LOG_FILE
cat $EXPORT_PATH/$LOG_FILE >> $LOGFILE
echo « Backup Completed. » >> $LOGFILE

echo « gzipping … » >> $LOGFILE
gzip $EXPORT_PATH/$DMP_FILE >> $LOGFILE
echo « gzipping Completed. » >> $LOGFILE

echo « Deleting old files » >> $LOGFILE
find $EXPORT_PATH -type f -mtime +31 | xargs rm >> $LOGFILE
echo « Delete Completed » >> $LOGFILE

cat $LOGFILE | mail -s « expdp-`date + »%d%m%Y_%T »` » $ADMIN_EMAIL

Here is for the cron tab:

30 23 * * * /opt/oracle/admin/acisora1/scripts/export_backup.sh >> /dev/null

the script will be executed avery at 11:30 pm
