环境:
OS:Red Hat Linux As 5
DB:11.2.0.1(ASM)
1.查看当前控制文件
SQL> select name from v$controlfile;
NAME
--------------------------------------------------------------------------------
+DATA/oracl/controlfile/current.260.794393131
2.查看参数文件
SQL> show parameters control_files;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_files string +DATA/oracl/controlfile/curren
t.260.794393131
3.关闭数据库
shutdowm immediate
4.使用RMAN复制控制文件
[hxl.com::/]$rman target /
RMAN> startup nomount
Oracle instance started
Total System Global Area 338968576 bytes
Fixed Size 1336400 bytes
Variable Size 276827056 bytes
Database Buffers 54525952 bytes
Redo Buffers 6279168 bytes
RMAN> restore controlfile to '+RECDATA' from '+DATA/oracl/controlfile/current.260.794393131';
Starting restore at 2012-09-21 06:53:56
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=23 device type=DISK
channel ORA_DISK_1: copied control file copy
Finished restore at 2012-09-21 06:54:01
5.使用ASMCMD查看控制文件的名字
ASMCMD> pwd
+recdata/oracl/CONTROLFILE
ASMCMD> ls
current.265.794560115
新建的控制文件如下:
+RECDATA/oracl/controlfile/current.265.794560115
6.修改spfile
[hxl.com::/]$echo $ORACLE_SID
[hxl.com::/]$sqlplus /nolog
SQL*Plus: Release 11.2.0.1.0 Production on Fri Sep 21 06:57:42 2012

System altered.
SQL> shutdown immediate

7.查看修改后的参数
SQL> show parameters control_files;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_files string +DATA/oracl/controlfile/curren
t.260.794393131, +RECDATA/orac
l/controlfile/current.265.7945
