// *Cause: Database flashback is on but this instance failed to
//         start generating flashback data. Look in alert log for more
//         specific errors.
// *Action: Correct the error or turn off database flashback.

#1、关闭flash backup再open database
SQL> alter database flashback off;
SQL> alter database open;

#2、另外一种办法直接关闭数据库后再启动也是可以的
SQL> startup force mount;
