Answer: A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。
RMAN>BACKUP TABLESPACE users, example;
RMAN> SQL "ALTER TABLESPACE users, example ONLINE";
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。
