今天电脑非常卡，强制重启后，发现oracle 11g启动不了了，提示错误：

ERROR - ORA-01033 oracle initialization or shutdown in progress

解决步骤

首先sysdba账号登录下

很长时间没登录了，发现sys的密码忘记了，于是第一步，修改sys账号的密码：

orapwd file=%ORACLE_HOME%\database\PWDsid.ora password=zyh123

登录

conn sys/zyh123 as sysdba

关闭数据库

SQL> shutdown normal
ORA-01109: database not open


Database dismounted.
ORACLE instance shut down.

启动数据库

SQL> startup
ORACLE instance started.

错误原因：一般为存储异常断电,导致数据库启动报ORA-01172错,导致数据库无法open
