626.Which options must you configure while performing an automated Tablespace Point-in-Time

Recovery (TSPITR) by using Recovery Manager (RMAN)?

A. New channels for restore and recovery tasks

B. New name for the data files of the tablespace

C. Auxiliary name for the data files of the tablespace

D. Auxiliary destinations for an auxiliary set of data files

Answer: D

答案解析：

执行完全自动执行的TSPITR

1. 配置在目标实例上执行TSPITR 所需的通道。

2. 使用AUXILIARY DESTINATION选项指定辅助目标。

RMAN> CONNECT TARGET

RMAN> RECOVER TABLESPACE users, example

> UNTIL TIME '2007-06-29:08:00:00'

> AUXILIARY DESTINATION

> '/u01/app/oracle/oradata/aux';

3. 备份恢复的表空间并使它们联机。

执行完全自动执行的TSPITR 时，还必须：

• 配置在目标实例上执行TSPITR 所需的任何通道

• 指定RMAN 用于数据文件辅助集和其它辅助实例文件的目标

在TSPITR 完成之后，备份恢复的表空间并使它们联机。执行TSPITR 之后，不能使用TSPITR 之前创建的参与执行TSPITR 的表空间的备份。

 

Performing Fully Automated RMAN TSPITR

In the default mode, RMAN bases as much of the configuration for TSPITR as possible on the target database. During TSPITR, the recovery set data files are written in their current locations on the target database . The same channel configurations for the target database are used on the auxiliary instance when restoring files from backup. Auxiliary set data files and other auxiliary instance files, however, are stored in the auxiliary destination.

Use the AUXILIARY DESTINATION parameter to set a location for RMAN to use for the auxiliary set data files. The auxiliary destination must be a location on disk with enough space to hold auxiliary set data files. Even if you use other techniques to rename some or all of the auxiliary set data files, specifying an AUXILIARY DESTINATION parameter provides a default location for auxiliary set data files for which names are not specified. TSPITR does not fail if you inadvertently omit some names of the auxiliary set data files.
