Enable Archivelog mode, run an Oracle Database Backup using Rman, and verify backup existence

How to Enable ARCHIVELOG Mode ,Take a database Backup, and Verify backup existence Running a Database in ARCHIVELOG Mode When you enable ARCHIVELOG mode, it allows for the archiving of redo log files. The database control file tracks the filled redo log files, preventing the LGWR process from reusing them until they are archived. After a redo log switch occurs, the filled redo log files can be archived. Benefits of Enabling ARCHIVELOG Mode: Database Recovery: With archived redo logs, you can fully recover committed transactions in case of a system or disk failure. Backup Flexibility: You can take backups even while the database is open and actively used. Standby Database Synchronization: Archiving redo logs keeps a standby database synchronized with the primary database by applying archived logs continuously. ARCHIVELOG mode ensures that redo logs, which contain all changes made to the database, are archived when full, rather than being overwritten. This provides important recovery options. --Check the database name, open state and archivelog mode: select name, open_mode, log_mode from v$database; --Start the database in MOUNT state: shutdown immediate startup mount ---Enable ARCHIVELOG mode: alter database archivelog; alter database open; ---Verify ARCHIVELOG mode is enabled: select name, open_mode, log_mode from v$database; ---Start RMAN and take a full database backup: rman target / backup database; ----Verify the backup location and files: cd /app/oracle/fast_recovery_area/ cd backupset/2025_02_01/ 😉more videos ? : / cesarbrothertech.com 💛Don't forget to, 💘Follow, 💝Like, 💖Share 💙&, Comment
