Oracle Data Guard_ 主备库传输表空间

8.3.3 Using Transportable Tablespaces with a Physical Standby Database

8.3.3 物理备库使用传输表空间

You can use the Oracle transportable tablespaces feature to move a subset of an Oracle database and plug it in to another Oracle database, essentially moving tablespaces between the databases.

你可以使用oracle传输表空间特征，从oracle数据库的一个子集传输到另一个oracle数据库，实质上是在数据库将移动表空间。

To move or copy a set of tablespaces into a primary database when a physical standby is being used, perform the following steps:

当备库在使用时，移动或者拷贝一组表空间到主库，执行以下步骤：

1. Generate a transportable tablespace set that consists of datafiles for the set of tablespaces being transported and an export file containing structural information for the set of tablespaces.

   1.得到包含要被传输的一组表空间集，导出包括这一组表空集的框架信息的文件。

   
   

2. Transport the tablespace set:

   2.传输表空间集

   
   

   1. Copy the datafiles and the export file to the primary database.

      1.拷贝数据文件，并导出文件到主库。

      
      

   2. Copy the datafiles to the standby database.

      2.拷贝数据文件到备库。

      
      

   The datafiles must be copied in a directory defined by the DB_FILE_NAME_CONVERT initialization parameter. If DB_FILE_NAME_CONVERT is not defined, then issue the ALTER DATABASE RENAME FILE statement to modify the standby control file after the redo data containing the transportable tablespace has been applied and has failed. The STANDBY_FILE_MANAGEMENT initialization parameter must be set to AUTO.

   数据文件必须拷贝到DB_FILE_NAME_CONVERT初始化指定的目录，如果DB_FILE_NAME_CONVERT没有定义，那么在失败后，包含传输表空间被应用的重做数据，可以发出 ALTER DATABASE RENAME FILE语句来改变备用控制文件。STANDBY_FILE_MANAGEMENT参数必须要设置为AUTO。

   
   

3. Plug in the tablespace.

   3.插入表空间

   Invoke the Data Pump utility to plug the set of tablespaces into the primary database. Redo data will be generated and applied at the standby site to plug the tablespace into the standby database.

   调用数据泵来把这一组表空间插入到主数据库，则备库就会得到重做数据并应用，将表空间插入到备库中。
