>>> how to disable compression in oracle rman backup
By default, Oracle RMAN (Recovery Manager) compresses the backup data to reduce storage requirements and improve transfer times. However, there may be
scenarios where you want to disable compression for specific backups or for a particular reason.

To disable compression in an Oracle RMAN backup, you can use the `COMPRESSION` parameter with a value of `OFF` when executing the `BACKUP` command. Here
are some examples:

1. Disable compression for a single backup:
„`sql
RMAN> BACKUP DATABASE COMPRESSION OFF;
„`
This will create a compressed backup of your entire database.

2. Disable compression for a specific tablespace or datafile:
„`sql
RMAN> BACKUP TABLESPACE <tablespace_name> COMPRESSION OFF;
„`
Replace `<tablespace_name>` with the name of the tablespace you want to back up without compression.

3. Disable compression for a specific database file (e.g., an individual datafile):
„`sql
RMAN> BACKUP FILE ‚<datafile_name>‘ COMPRESSION OFF;
„`
Replace `<datafile_name>` with the full path and name of the database file you want to back up without compression.

4. Set the default compression setting for all future backups:
„`sql
RMAN> CONFIGURE DEFAULT DEVICE TYPE TO ‚DISK‘ COMPRESSION OFF;
„`
This sets the default compression setting for all subsequent backups that use the `BACKUP` command with no specific compression setting specified.

Remember to adjust the `COMPRESSION` parameter according to your specific requirements and storage constraints.
