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';
