startup upgrade 是什么意思?

easytolab

系统startup 报错:ORA-01092: ORACLE instance terminated. Disconnection forced

查TRACE发现Errors in file /oracle/product/10g/oracle10/saptrace/usertrace/cer_ora_11846.trc:
ORA-00704: bootstrap process failure
ORA-39700: database must be opened with UPGRADE option
Mon Nov 28 13:02:38 2005
Error 704 happened during db open, shutting down database
USER: terminating instance due to error 704
Instance terminated by USER, pid = 11846
ORA-1092 signalled during: ALTER DATABASE OPEN...


后执行>startup upgrade成功

想知道问题的原因和执行upgrade option的道理, 请大家赐教.
