oracle手工创建控制文件
sql>shutdown immediate;
sql>startup
nomount;
sql>alter databse database mount;
sql>alter database backup
controlfile to trace;
注意：sql>alter database backup controlfile to
trace这条SQL必须在数据库mount的情况下才能执行，不如会报ora-01507错误
此时你的控制文件以及转存储到${oracle_home}\admin\orcl\udump\??
本人电脑的路径是：D:\oracle\product\10.2.0\db_1\admin\orcl\udump\orcl_ora_7992.trc(这个文件是最新的，windows下按照时间排序找出最新的那个)，
用记事本或者UE打开，内容如下：
Dump

蓝色部分的SQL就是用来创建控制文件的，下面让我们模拟一下数据库控制文件损坏的情况
SQL>shutdown
immediate;
然后把数据库的控制文件剪切到其他文件夹，此时oracle无法找到控制文件
SQL>startup
nomount;
SQL>alter database
mount;
ora-00205:??????????????
*因为此时oracle找不到控制文件，报0ra-00205错误，当然此时你可以通过修改spfile参数文件，把控制文件的路径修改为你最新的控制文件路径，这个以后再介绍。
此时提供了两种不同SQL创建控制文件，我选了第一种：
SQL>CREATE
CONTROLFILE REUSE DATABASE "ORCL" NORESETLOGS NOARCHIVELOG
MAXLOGFILES
16
MAXLOGMEMBERS
3
MAXDATAFILES
100
MAXINSTANCES
8
MAXLOGHISTORY
292
LOGFILE
GROUP 1 ‘D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\REDO01.LOG‘ SIZE
50M,
GROUP
2 ‘D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\REDO02.LOG‘ SIZE
50M,
GROUP
3 ‘D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\REDO03.LOG‘ SIZE
50M
-- STANDBY
LOGFILE
DATAFILE
‘D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\SYSTEM01.DBF‘,
‘D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\UNDOTBS01.DBF‘,
‘D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\SYSAUX01.DBF‘,
‘D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\USERS01.DBF‘,
‘D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\EXAMPLE01.DBF‘,
‘D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\USR_DATA.DBF‘
CHARACTER
SET ZHS16GBK
;
--控制文件已创建
SQL>RECOVER DATABASE;
SQL> ALTER DATABASE
OPEN;
--数据库已更改，此时数据库可以正常open了
--修改临时表空间，*因为刚才的创建控制文件的SQL中没有指定临时表空间，所以要从新设定临时表空间
SQL> ALTER TABLESPACE
TEMP ADD TEMPFILE ‘D:\oracle\product\10.2.0\oradata\orcl\temp01.dbf‘
2 SIZE 41943040 REUSE AUTOEXTEND ON
NEXT 655360 MAXSIZE 32767M;
--数据库可以正常使用，成功！此时再查看D:\oracle\product\10.2.0\oradata\orcl文件夹，同时存在CONTROL01.CTL,CONTROL02.CTL,CONTROL03.CTL，
这表明oracle创建控制文件会自动生成3个。
