Data Gurad物理备份方式下standby_file_management为manual时修改表空间的操作

STANDBY_FILE_MANAGEMENT设置为MANUAL，增加及删除表空间和数据文件

SQL> show parameter standby_file_management

 

NAME                                TYPE        VALUE

------------------------------------ ----------- ------------------------------

standby_file_management              string      AUTO

SQL> alter system set standby_file_management='MANUAL' scope=both;

 

System altered.

 

SQL> show parameter standby_file_management

 

NAME                                TYPE        VALUE

------------------------------------ ----------- ------------------------------

standby_file_management              string      MANUAL

A).增加新的表空间--primary 数据库操作

SQL>CREATE  TABLESPACE mytest DATAFILE '/u01/app/Oracle/oradata/jytest/mytest01.dbf' size 20M

 

SQL> select name from v$datafile;

 

NAME

--------------------------------------------------------------------------------

/u01/app/oracle/oradata/jytest/system01.dbf

/u01/app/oracle/oradata/jytest/undotbs01.dbf

/u01/app/oracle/oradata/jytest/sysaux01.dbf

/u01/app/oracle/oradata/jytest/users01.dbf

/u01/app/oracle/oradata/jytest/hygeia01.dbf

/u01/app/oracle/oradata/jytest/mytest01.dbf

 

6 rows selected

 

切换日志

SQL> alter system switch logfile;

 

System altered

B).验证standby 库--standby 数据库操作

SQL> select name from v$datafile;

 

NAME

--------------------------------------------------------------------------------

/u01/app/oracle/oradata/jytest/system01.dbf

/u01/app/oracle/oradata/jytest/undotbs01.dbf

/u01/app/oracle/oradata/jytest/hygeia01.dbf

/u01/app/oracle/product/10.2.0/db/dbs/UNNAMED00006

可以看到，表空间已经自动创建，但是，数据文件却被起了个怪名字，手工修改其与primary

数据库保持一致.

SQL>alter database create datafile

'/u01/app/oracle/product/10.2.0/db/dbs/UNNAMED00006'

as '/u01/app/oracle/oradata/jytest/mytest01.dbf';

 

C).删除表空间--primary 数据库操作

SQL> drop tablespace mytest including contents and datafiles;

 

Tablespace dropped

 

SQL> select name from v$datafile;

/u01/app/oracle/oradata/jytest/users01.dbf

/u01/app/oracle/oradata/jytest/hygeia01.dbf

 

SQL> alter system switch logfile;

 

System altered

D).验证standby 数据库--standby 数据库操作

 

SQL> select name from v$datafile;

数据还在啊。查看alertjytest.log 文件，发现如下

MRP0: Background Media Recovery terminated with error 1274

重启redo 应用再来看看：

SQL> alter database recover managed standby database disconnect from session;

 

Database altered.

 

SQL> select name from v$datafile;
