我们在操作Oracle的时候,如果出现Oracle无法正常启动或停止,或者Oracle的导入导出命令执行错误,

通常是由于Oracle的实例下的表空间出现了问题造成的。

以下解决办法,摘自网络,适用于各种表空间文件出现问题的状况:

ora-01033:oracle initialization or shutdown in progress,经过分析研究终于解决了

一、首先:问题的产生原因,出现这个错误是因为我将oracle\oradata\oradb下的一个文件误删除掉后出现的。

二、现象:SQL*Plus无法连接,显示以下错误: ORA-01033: ORACLE initialization or shutdown in progress ,Enterprise Manager Console中也是同样的错误。

三、分析:应该是Oracle在启动后,用户登录时是要将方案中原有配置信息装载进入,,装载过程中遇到原有文件指定的位置上没有找到,所以就报出错误。

四、解决过程:

1、先在windows下运行cmd,进入DOS环境。
2、以DBA用户登录,具体命令是
sqlplus /NOLOG
SQL>connect sys/change_on_install as sysdba
提示:已成功

SQL>shutdown normal
提示:数据库已经关闭
已经卸载数据库
ORACLE 例程已经关闭

SQL>startup mount
提示:ORACLE例程已经启动
Total System Global Area 118255568 bytes
Fixed Size                  282576 bytes
Variable Size             82886080 bytes
Database Buffers          33554432 bytes
Redo Buffers                532480 bytes
数据库装载完毕

SQL>alter database open;
提示:
第 1 行出现错误:
ORA-01157: 无法标识/锁定数据文件 19 - 请参阅 DBWR 跟踪文件
ORA-01110: 数据文件 19: ''''C:\oracle\oradata\oradb\FYGL.ORA''
这个提示文件部分根据每个人不同情况有点差别。

继续输入
SQL>alter database datafile 19 offline drop;
提示:数据库已更改。

循环使用最后两步,直到alter database open;后不再提示错误,出现“数据库已更改”。
然后接着输入即可
SQL>shutdown normal
提示:数据库已经关闭
已经卸载数据库
ORACLE 例程已经关闭

SQL>startup
提示:ORACLE例程已经启动
Total System Global Area 118255568 bytes
Fixed Size                  282576 bytes
Variable Size             82886080 bytes
Database Buffers          33554432 bytes
Redo Buffers                532480 bytes
数据库装载完毕

就可以解决了。
5、最后说一下,第一条提到的隐患,因为创建了新的库,ORACLE_SID也就发生了变化,在用户登录的时候会有ORA-12560错误,解决这个问题是将系统注册表中的HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOME0\ORACLE_SID
键值修改成之前那个SID就可以了,用户也能就能正常登录了。
