Database backups are critical for ensuring data security and business continuity. As part of database management, I recently worked on scheduling Oracle RMAN backups using shell scripting and cron jobs.
Here’s a quick overview of how you can automate this process:
1️⃣ Create a Shell Script to invoke RMAN commands for database backup.
2️⃣ Schedule the Script using a Cron job to run automatically at specified intervals.
3️⃣ Monitor the logs to ensure successful backups.
💡 Here’s a sample shell script to schedule RMAN backups:
ORACLE_HOME=/u01/app/oracle/product/19.0.0/dbhome_1
ORACLE_SID=orcl
LOG_FILE=/backup/logs/rman_backup_$(date +%Y%m%d_%H%M%S).log
BACKUP_DIR=/backup/rman
export ORACLE_HOME ORACLE_SID PATH=$ORACLE_HOME/bin:$PATH
$ORACLE_HOME/bin/rman target / < $LOG_FILE
RUN {
ALLOCATE CHANNEL c1 DEVICE TYPE DISK;
BACKUP DATABASE FORMAT ‘$BACKUP_DIR/db_%U.bkp’;
BACKUP ARCHIVELOG ALL FORMAT ‘$BACKUP_DIR/arch_%U.bkp’;
DELETE OBSOLETE;
RELEASE CHANNEL c1;
}
EXIT;
EOF
if grep -q “RMAN-” $LOG_FILE; then
echo “Backup failed. Check the log file: $LOG_FILE”
else
echo “Backup completed successfully. Log file: $LOG_FILE”
fi
💻 To schedule the backup, add a cron job:
0 2 * * * /path/to/backup_script.sh
This setup ensures that your backups are automated and logs are maintained for easy troubleshooting.
