一、实验说明：
本实验是基于： 《丢失控制文件恢复实验记录--1(当前的控制文件损坏，使用旧控制文件进行恢复(旧控制文件之后DROP了表空间的情况))》 和 《丢失控制文件恢复实验记录--2(当前的控制文件损坏，使用旧控制文件进行恢复(旧控制文件之后新增了表空间的情况))》，把这两个实验的情况综合以后做一个恢复实验。
操作系统：rhel 5.4 x32
数据库:oracle 11g r2
二、操作内容：
下面是恢复的另一种方法，是在恢复控制文件以后再重建控制文件，再基于控制文件恢复。
本实验是基于： 《丢失控制文件恢复实验记录--1(当前的控制文件损坏，使用旧控制文件进行恢复(旧控制文件之后DROP了表空间的情况))》 和 《丢失控制文件恢复实验记录--2(当前的控制文件损坏，使用旧控制文件进行恢复(旧控制文件之后新增了表空间的情况))》，把这两个实验的情况综合以后做一个恢复实验。
操作系统：rhel 5.4 x32
数据库:oracle 11g r2
二、操作内容：
----首先做一个当前控制文件的备份----
