创建控制文件脚本，重建控制文件

alter database backup controlfile to trace

1、alter session set tracefile_identifier='bak_control';【为session加上标记，方便查找trace文件

2、alter database backup controlfile to trace;【将当前controlfile文件的创建语句放到了trace文件中

3、select tracefile from v$process where addr in (select paddr from v$session where sid in (select sid from v$mystat));【获得当前trace文件生成路径】
  或select value from v$diag_info where name='Default Trace File';

cd /u02/app/oracle/diag/rdbms/orcl/orcl1/trace/

ls -lt *bak_control*

4、cat orcl1_ora_28738_bak_control.trc【查看一下生成的trace文件】

[oracle@rac1 trace]$ cat orcl1_ora_28738_bak_control.trc

Trace file /u02/app/oracle/diag/rdbms/orcl/orcl1/trace/orcl1_ora_28738_bak_control.trc

5、NORESETLOGS VS RESETLOGS

从trace文件可以看出，提供了两个创建控制文件的脚本，分别针对两种不同的应用场景：NORESETLOGS适用于当前redo log可用，而RESETLOGS适用于当前redo log不可用。

6.1NORESETLOGS重建步骤

1.执行脚本，重建控制文件（CREATE CONTROLFILE REUSE DATABASE "HOEGH" NORESETLOGS NOARCHIVELOG......）

2.执行介质恢复RECOVER DATABASE

3.打开数据库ALTER DATABASE OPEN;

4.添加临时表空间

6.2RESETLOGS重建步骤

1.执行脚本，重建控制文件（CREATE CONTROLFILE REUSE DATABASE "HOEGH" RESETLOGS NOARCHIVELOG......）

2.执行介质恢复RECOVER DATABASE USING BACKUP

 CONTROLFILE

3.打开数据库ALTER DATABASE OPEN RESETLOGS;

4.添加临时表空间

下面测试来自网络 ：

运行这个脚本即可重建控制文件:

以上给出生成创建控制文件脚本并重建控制文件的方法，但是具体恢复中遇到的问题可能需要具体对待.

这种方法通常是在没有控制文件(二进制文件)备份的情况下所采用的，如果存在备份应该使用备份的控制文件尝试恢复
