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命令从一个恢复目录方案向另一个不同的恢复目录方案导入数据.
如果创建不同版本的目录方案来存储多个目标数据库的元数据,则这个命令允许你为多个数据库维护单个恢复目录.
NO UNREGISTER--强制RMAN在源目录方案中仍然保存导入数据库的ID. 因为默认被导入的数据库的ID会从源恢复目录方案中取消注册.
