• 创建表空间后无RMAN备份的恢复


    做RMAN恢复测试时遇到的一个问题:
    1、RMAN全备份数据库(数据库为ARCHIVE LOG模式)
    2、在数据库上创建新的表空间
    3、备份所有归档日志
    4、关闭数据库并将数据库里面的控制文件、数据文件全部删除
    5、用RMAN进行恢复
    RMAN>set dbid ...
    RMAN>startup nomount
    RMAN>restore controlfile from autobackup;
    RMAN>alter database mount;
    RMAN>restore database-------这一步出错,提示无法找到新创建表空间的数据文件的备份


    这是否说明上面第二步中创建表空间后应使用RMAN备份该表空间?如果没有备份的话,数据库真的不能恢复吗?应该还是能够恢复的吧,但具体应该怎么做呢?
