RMAN-06149: cannot BACKUP DATABASE in NOARCHIVELOG mode

Oracle Database

Running a database in noarchivelog mode disables the possibility of database recovery as we will not have any archived redo logs to apply to the restored data files and only way of recovery is reverting database to the last full backup and in the same process be ready to loose all changes made after the full backup. This is why oracle does not recommend running database in NOARCHIVELOG mode and does not allow full database backups when database is on noarchivelog mode.

Here we will discuss how to workaround the “RMAN-06149: cannot BACKUP DATABASE in NOARCHIVELOG mode” error while taking RMAN database backups while running the DB on NOARCHIVELOG mode.

Error Seen while backing whole database via RMAN:

C:\Users\techpaste>rman target sys/Welcome1

RMAN-06149: cannot BACKUP DATABASE in NOARCHIVELOG mode

To overcome “RMAN-06149: cannot BACKUP DATABASE in NOARCHIVELOG mode” issue we have to take cold backup of database by following below steps:

1. Shutdown database
2. Startup database in mount mode
3. Execute backup database command.
4. Check backup taken successfully.
5. Start database open.
Example:

Connect to RMAN:

C:\Users\techpaste>rman target sys/Welcome1

Startup database in mount mode:

RMAN> startup mount;

rman database restart

Set the RMAN backup destination folder:

RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'D:\Projects\Backups\full_%u_%s_%p';

old RMAN configuration parameters:
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'D:\Projects\Backups\full_%u_%s_%p';
new RMAN configuration parameters:
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'D:\Projects\Backups\full_%u_%s_%p';
new RMAN configuration parameters are successfully stored

rman set backup destination

Check all configurations are correct or not:
