RMAN-03002: restore 命令 (在 12/25/2015 12:43:34 上) 失败
ORA-19693: 已包括备份片段 C:DATADB_1LQPCVBI_1_1

原因：
与BUG 4483368有关，通过list backup summary可以发现备份集有多个副本数

RMAN> list backup summary;

解决方案：

1.查找出副本数大于1的备份集，如list backup summary
2.重命名对应的备份集，或者将备份集移动到其它某个位置
3.使用crosscheck backup检测出无效的备份集
4.使用delete noprompt expired backup删除无效备份集
5.使用CATALOG START WITH重新添加备份集
6.重新执行RMAN操作

RMAN> crosscheck backup tag 'TAG20151221T172922' ;
