在网上看到的重装主机Oracle DB的处理,觉的很好,很实用,先记录一下,,以后可能用的着。

1.将原来的Oracle文件夹重命名,比如oracle_old;然后重新安装oracle

到原目录,即跟重装操作系统前同一目录,假设为d:\oracle;安装过程选择"只安装软件"

即不创建数据库,这样可以节省很多时间.

注:恢复必须要有以下文件

a、初始化参数文件INIT.ORA

b、所有数据文件 .dbf

c、所有重做日志文件(联机日志、归档日志)redo

d、所有控制文件 crtl

e、internal密码文件

2.配置listener和tns:

运行lsnrctl start,即可在创建监听服务;

使用net manager配置tns,但不要测试(数据库没有起来肯定测试不通过的);

3.将oradata文件夹拷贝回原目录(如d:oracleoradata);

4.将spfile拷贝回原目录(如d:oracleora92database);

5.创建实例服务:

oradim -new -sid orcl -startmode auto

6.重建口令文件:或是复制原来的pwdorcl.ora yhy9为实例名

orapwd file=d:oracleora92database password=orcl entries=5

7.重启监听和实例.

8.如果数据库没有启动就进入sqlplus手工打开数据库

sqlplus /nolog

sql>conn sys/orcl@orcl as sysdba

sql>startup;

一定要有提示成功打开,否则重复以上办法解决。

9.如果数据库顺利打开,整个实例恢复过程即完成.

经验证通过以上操作,完全可以恢复成功。需要的是耐心、细心。

如果中间有报错,则一步步根据报错到网上查找解决办法。
