dataguard从库移动数据文件

------------方法1从库移动数据文件路径方法1--------------

将表空间offline的方法不行

1.退出日志应用

alter database recover managed standby database cancel;

2.修改表空间为离线状态

SQL> alter tablespace TPS_DATA offline;

alter tablespace TPS_DATA offline

*

ERROR at line 1:

ORA-16000: database open for read-only access

3.复制表空间对应文件到新的位置

cd /u01/app/oracle/oradata

mv tps_data02.dbf /u01/app/oracle/oradata/slnngkdg/tps_data03.dbf

4、修改表空间数据文件路径

SQL> alter tablespace TPS_DATA rename datafile '/u01/app/oracle/oradata/tps_data02.dbf' to 'u01/app/oracle/oradata/slnngkdg/tps_data03.dbf';

5、修改表空间为在线状态

SQL> alter tablespace sysaux TPS_DATA;

------------方法2从库移动数据文件路径方法1--------------

1.退出日志应用

alter database recover managed standby database cancel;

2.关闭数据库

shutdown immediate

3.拷贝原来的数据文件到新的地方

cd /u01/app/oracle/oradata

mv tps_data02.dbf /u01/app/oracle/oradata/slnngkdg/tps_data03.dbf

4.启动到mount

SQL> startup mount

5.修改数据库路径

alter database rename file '/u01/app/oracle/oradata/tps_data02.dbf' to '/u01/app/oracle/oradata/slnngkdg/tps_data03.dbf';

SQL> alter database rename file '/u01/app/oracle/oradata/tps_data02.dbf' to '/u01/app/oracle/oradata/slnngkdg/tps_data03.dbf';

alter database rename file '/u01/app/oracle/oradata/tps_data02.dbf' to 'u01/app/oracle/oradata/slnngkdg/tps_data03.dbf'

*

ERROR at line 1:

ORA-01511: error in renaming log/data files

ORA-01275: Operation RENAME is not allowed if standby file management is automatic.

解决办法:

alter system set standby_file_management = MANUAL;

6.启用日志

alter database recover managed standby database using current logfile disconnect from session;

7.打开数据库

alter database recover managed standby database cancel;

alter database open;

--再次引用

alter database recover managed standby database using current logfile disconnect from session;

8.修改 standby_file_management 为 auto

alter system set standby_file_management = auto;

9.尝试在主库创建一个文件

alter tablespace TPS_DATA add datafile '/u01/app/oracle/oradata/slnngk/tps_data04.dbf' size 10m;

可以看到从库日志也相应添加的了数据文件
