oracle用户管理的完全恢复5：控制文件损坏（控制文件前后内容未改变）

场景描述：控制文件损坏（控制文件内容没有变化）

1.备份

1 SQL> alter database backup controlfile to trace as '/u01/admin/sun/udump/c.trc';
2 
3 Database altered.

5 SQL>

2.删除备份文件

 1 -bash-3.00$ ls -l
 2 total 2183024
 3 -rw-r-----   1 oracle   oinstall 7061504 Jan 23 03:12 control01.ctl
 4 -rw-r-----   1 oracle   oinstall 7061504 Jan 23 03:12 control02.ctl

12 -rw-r-----   1 oracle   oinstall 251666432 Jan 23 03:07 sysaux01.dbf
13 -rw-r-----   1 oracle   oinstall 503324672 Jan 23 03:10 system01.dbf
14 -rw-r-----   1 oracle   oinstall 20979712 Jan 22 23:24 temp01.dbf
15 -rw-r-----   1 oracle   oinstall 31465472 Jan 23 03:10 undotbs01.dbf
16 -rw-r-----   1 oracle   oinstall 5251072 Jan 23 03:01 users01.dbf
17 -bash-3.00$ rm -f control01.*
18 -bash-3.00$

3.关机

1 SQL> shutdown abort
2 ORACLE instance shut down.
3 SQL>

4.更改备份的控制文件

 1 -bash-3.00$ pwd  
 2 /u01/admin/sun/udump
 3 -bash-3.00$ cp c.trc c.sql
 4 
 6 将注释和多余的信息从控制文件中删除
 7 -bash-3.00$ vi c.sql
