Oracle Data Guard_ 主库删除表空间

8.3.2.1 When STANDBY_FILE_MANAGEMENT Is Set to AUTO or MANUAL

The following procedure works whether the STANDBY_FILE_MANAGEMENT initialization parameter is set to either MANUAL or AUTO, as follows:

以下的步骤不管STANDBY_FILE_MANAGEMENT参数设置为MANUAL还是AUTO，都能工作，如下：

1. Drop the tablespace from the primary database:

   1.从主库删除一个表空间

   SQL> DROP TABLESPACE tbs_4;

   SQL> ALTER SYSTEM SWITCH LOGFILE;
   
   

2. Make sure that Redo Apply is running (so that the change is applied to the standby database). If the following query returns the MRP or MRP0 process, Redo Apply is running.

   确保重做应用在运行，这样备库就会应用这些变化。如果以下的查询返回的MRP或者MRP0进程，则说明重做应用在运行

   
   

   SQL> SELECT PROCESS, STATUS FROM V$MANAGED_STANDBY;
   
   

   To verify that deleted datafiles are no longer part of the database, query the V$DATAFILE view.

   验证已经删除的数据文件不再存在数据库中，可查询V$DATAFILE视图。

   
   

3. Delete the corresponding datafile on the standby system after the archived redo log file was applied to the standby database. For example:

   在归档重做日志被应用再备库之后，在备库删除相应的数据文件，例如：

   
   

   % rm /disk1/oracle/oradata/payroll/s2tbs_4.dbf
   
   

4. On the primary database, after ensuring the standby database applied the redo information for the dropped tablespace, you can remove the datafile for the tablespace. For example:

   在主库中，确保备库应用删除表空间的重做信息之后，你可以从表空间移除数据文件，例如：

   
   

   % rm /disk1/oracle/oradata/payroll/tbs_4.dbf
   
   

8.3.2.2 Using DROP TABLESPACE INCLUDING CONTENTS AND DATAFILES

You can issue the SQL DROP TABLESPACE INCLUDING CONTENTS AND DATAFILES statement on the primary database to delete the datafiles on both the primary and standby databases. To use this statement, the STANDBY_FILE_MANAGEMENT initialization parameter must be set to AUTO. For example, to drop the tablespace at the primary site:

你可以在主库上使用DROP TABLESPACE INCLUDING CONTENTS AND DATAFILES来删除主库和备库的数据文件，前提是STANDBY_FILE_MANAGEMENT必须设置为AUTO,例如，在主库上删除一个表空间：
