2：Handling Disk Space Issues
ORA-19504: failed to create file "/oraback/BRDSTN/bsi2phe7_1_1"
ORA-27004: unable to write the header block of file
解决：
Change the backup location to an area that has more space.
Add disk space to the backup location.
If using a flash recovery area (FRA), then either move the FRA or increase its size.
Change the retention policy to fewer days or fewer backups.
Delete old backup files that are no longer required
alter system set db_recovery_file_dest='/oraback02/FRA';
alter system set db_recovery_file_dest_size=100g;

4：Terminating RMAN Processes
Pre ss Ctrl+C from the RMAN interface. This approach, of course, works only if per-formed from the online session responsible for the process you want to terminate.
Manually kill the OS process.
kill -9 4123
Terminate the server session corresponding to an RMAN channel using an alter system kill SQL statement
SQL>SELECT s.sid ,s.serial# ,p.spid ,s.client_info FROM v$process p, v$session s WHERE p.addr = s.paddr AND client_info LIKE '%rman%';
SQL>alter system kill session '158,122';
5:Diagnosing NLS Character Set Issues
ORA-12705: Cannot access NLS data files or invalid environment specified
There’s a mismatch between the NLS character set of the client and that of the database server.
You have an NLS-related operating system variable that has been set incorrectly.
SQL> conn /as sysdba
Connected.
SQL> select value from v$nls_parameters where parameter = 'NLS_CHARACTERSET';
