ORA-19909: datafile string belongs to an orphan incarnation

ORA-19909: datafile string belongs to an orphan incarnation
Cause: Either the specified datafile was restored from a backup that was taken during a period of time that has already been discarded by a RESETLOGS operation, or Oracle cannot identify which database incarnation the file belongs to. The alert log contains more information.
Action: Restore a backup of this file that belongs to either the current or a prior incarnation of the database. If you are using RMAN to restore, RMAN will automatically select a correct backup.

ORA-19909：datafile 字符串属于孤儿incarnation,
.原因：从在RESETLOGS操作已经丢弃的时间段内所执行的备份中还原了指定的数据文件，或者Oracle无法确定文件属于哪个数据库文件。警报日志包含更多信息。,
.操作：恢复此文件的属于数据库的当前或先前版本的备份。如果使用RMAN进行恢复，RMAN将自动选择正确的备份。,
