解決方法：
通過備份的controlfile進行恢復
RMAN> list backup of controlfile;
但是通過rman查看備份的controlfile信息時，卻沒有！
還好，在磁盤上找到一個控制文件的backup piece！
加載到rman metadata中：
RMAN> catalog backuppiece '/backup/rman_bak/ctl1_166.bak';
cataloged backuppiece backup piece handle=/backup/rman_bak/ctl1_166.bak recid=191 stamp=859138553
RMAN> list backup of controlfile;
