OCP-1Z0-053-V12.02-251题

251.You are working on a CATDB database that contains an Oracle Database version 11.1 catalog

schema owned by the user RCO11. The INST1 database contains an Oracle Database version 10.1

catalog schema owned by the user RCAT10.

You want the RMAN to import metadata for database IDs 1423241 and 1423242, registered in RCAT10,

into the recovery catalog owned by RCO11.

You executed the following RMAN commands:

RMAN> CONNECT CATALOG rco11/password@catdb

RMAN> IMPORT CATALOG rcat10/oracle@inst1;

What happens when you execute the above commands? (Choose all that apply.)

A. They deregister all databases registered in the RCAT10 catalog.

B. They import metadata for all registered databases in the RCAT10 database.

C. They register all the RCAT10-catalog registered databases in the RCO11 catalog.

D. They overwrite all stored scripts in the RCO11 catalog with the same name as that in the RCAT10

catalog.

Answer: ABC

答案解析：

参考：http://blog.csdn.net/rlhua/article/details/13169205

使用IMPORT CATALOG命令可将元数据从一个恢复目录方案导入至其它目录方案中。如果创建了不同版本的目录方案来存储多个目标数据库的元数据，则使用此命令可以为所有数据库维护单个目录方案。

RMAN> CONNECT CATALOG rco11/password@catdb

1. RMAN 必须连接到需要将目录数据导入到的目标恢复目录，例如rco11 方案。

注：源恢复目录方案的版本必须等于RMAN 可执行文件的当前版本。导入早期版本的目录之前，必须将早期版本升级至RMAN 可执行文件的版本。

RMAN> IMPORT CATALOG rcat10/oracle@inst1;

2. 在本例中，ract10用户在inst1数据库中拥有一个RMAN 目录。你希望RMAN 导入所有注册的数据库并在源目录中注销这些数据库。

即是说，在RACT10目录中所有所注册的数据库到导入到rco11目录中，然后注销在ract10目录中所注册的数据库。
