rman 恢复过程中出现以下错误

RMAN> recover database;

ORA-01244: unnamed datafile(s) added to controlfile by media recovery
ORA-01110: data file 2: '/opt/oracle/oradata/xifenfei/xff01.dbf'

错误原因分析
在rman备份后，添加了数据文件，使用的是备份的控制文件进行恢复数据库导致（不能识别新的数据文件）
解决方法
通过sqlplus创建数据文件
SQL> alter database create datafile 2 as ‘/opt/oracle/oradata/xifenfei/xff01.dbf’;
Database altered.
然后继续在rman中执行恢复数据库操作
该情况说明
此中情况只有在oracle 9i中出现；在10g中，rman恢复过程会自动的创建新添加文件，见oracle 10g rman自动创建数据文件
