Oracle Fast Recovery Area: Set DB Recovery File Dest and Size

The Oracle Fast Recovery Area (FRA) is a disk location where Oracle stores and manages files related to backup and recovery. Two dynamic initialization parameters — db_recovery_file_dest and db_recovery_file_dest_size — control its location and maximum size, and both can be changed without restarting the database.

The Code

1-- Set the database recovery directory and size
2-- These settings are dynamic
3
4ALTER SYSTEM SET db_recovery_file_dest='<path>' SCOPE=BOTH;
5/
6ALTER SYSTEM SET db_recovery_file_dest_size=<size> SCOPE=BOTH;
7/

1Replace `<path>` with a valid file system path, ASM disk group, or NFS mount point, and replace `<size>` with a value like `100G`, `2T`, or `500M`.

What This Code Does

These two commands configure the Oracle Fast Recovery Area at the system level while the database is running. The SCOPE=BOTH clause means the change takes effect immediately in the running instance and is saved to the server parameter file (SPFILE), so it persists across database restarts.
