RMAN备份中常见的问题

1：ORA-01031insufficient privileges

gpasswd  -d Oracle dba --将oracle移除出dba组

查看oracle属性

uid=500(oracle) gid=500(oinstall) groups=500(oinstall)

RMAN-00554: initialization of internal recovery manager package failed
RMAN-04005: error from target database:
ORA-01031: insufficient privileges

解决：

usermod  -d /home/oracle/ -G dba  oracle --将oracle用户加入dba组

[root@oracle10g ~]# usermod  -d /home/oracle/ -G dba oracle
[root@oracle10g ~]# su - oracle
[oracle@oracle10g ~]$ rman target  /

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;

3：RMAN-06059 Error

RMAN> backup database plus archivelog;

Additional information: 3

解决：

RMAN> crosscheck archivelog all;

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';
