Oracle 11G OCP 1Z0-053 26

（26）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 commands:

RMAN>CONNECT CATALOG rco11/password@catdb

RMAN>IMPORT CATALOG rcat10/oracle@inst1 NO UNREGISTER;

Which two statements are true regarding the tasks accomplished with these commands?(Choose two.)

A. They import all metadata from the RCAT10 catalog.

B. They unregister the database from the RCAT10 catalog.

C. They do not register the databases registered in the RCAT10 catalog.

D. They register all databases registered in the RCAT10 catalog.

答案：（A、D）

解析：

使用IMPORT CATALOG命令從一個恢復目錄方案向另一個不同的恢復目錄方案匯入資料.

如果建立不同版本的目錄方案來儲存多個目標資料庫的後設資料,則這個命令允許你為多個資料庫維護單個恢復目錄.

NO UNREGISTER--強制RMAN在源目錄方案中仍然儲存匯入資料庫的ID. 因為預設被匯入的資料庫的ID會從源恢復目錄方案中取消註冊.
