PROBLEM:

While taking rman backup, it failed with below error ( ORA-19809 & ORA-19804)

SOLUTION:

1. Check the value of db_recovery_file_dest_size:

2. Check the space usage in recovery_dest

We can see out of 5G, 4.5G is already used. Let’s increase the value of db_recovery_file_dest to a higher value.

3. Increase db_recovery_file_dest

Run the rman job again, It will complete successfully.
