找到原因了:解决:

Subject:         ORA-600 [2252] Occurs During Alter Database Open
          Doc ID:         Note:253977.1         Type:         PROBLEM
          Last Revision Date:         19-OCT-2004         Status:         PUBLISHED


Symptom(s)
~~~~~~~~~~

After shutdown of the database you receive the following error during
alter database open:  ora-600 [2252]

You did not restore the database before receiving this error.


Cause
~~~~~~~

The system date is lower than the date of the shutdown.

While opening the database, Oracle compares the given SCN value
with the reasonable upper limit value calculated based on the
system date. If Oracle detects the provided scn is too large,
ORA-600[2252] would be raised.

Fix
~~~~
Set the system date equal or higher the date of the shutdown.
