重做系统后 恢复oracle 实例
第一次进行操作，按照网上方法，试了一遍，很多细节搞不清楚,但是还是要记录一下.
备份 old数据库
所用到文件有:
XXXXXX\product\11.2.0\dbhome_1\database\pwdXXXX.ora文件
XXXXXX\flash_recovery_area\XXXXXXXX\CONTROL02.ctl文件
XXXXXX\oradata\xxxxxxxxx\下的所有文件
为了成功，选择与之前安装的oracle相同版本相同路径，进行安装。推荐不要安装数据库。
通过 Database Configuration Assistant 新建实例，尽量与之前实例相同。
准备工作完毕
关闭oracle实例 监听
用备份文件替换新的文件。
开启 实例 监听
cmd下 set oracle_sid=xxxxxx;
登入 sysdba 账户
若是新安装的oracle路径不对,修改XXXXXX\oradata\xxxxxxxxx\实例下的所有文件路径。
