While performing a regular check on your recovery catalog you realized that the catalog database is running out of space and you do not have options to increase the space. However, you have another database where more space is available and you want to move your existing recovery catalog to this database.
The options that can be considered while moving the recovery catalog are as follows:
1. Using one of the Oracle expdp utilities to export the catalog data
2. Creating a recovery catalog user and granting the necessary privileges in the other database
3. Creating the recovery catalog using the CREATE CATALOG command
4. Using the corresponding impdp utility to import the catalog data into the other database
5. Registering the target database in the new catalog database using the REGISTER DATABASE
command Identify the option with the correct sequence for moving the recovery catalog.
A. 2, 3, 5
B. 1, 2, 4
C. 1, 2, 4, 5
D. 1, 2, 3, 4, 5
此处是使用 expdp 工具完成逻辑备份，然后导入到新数据库完成移动的过程，此过程和使用 RMAN 命令IMPORT 不同，不需要使用 CREATE CATALOG 命令创建目录，因为导出的备份中包含，导入的时候会重建恢复目录。
使用此方式移动恢复目录的步骤：
1.导出恢复目录数据。
2.在导入的数据库上建立恢复目录用户，授予必要的权限。
3.然后导入。
