Oracle Study之案例--在RAW上controlfile多元化
系统环境:
操作系统: AIX 5300-08
数据库: Oracle 10.2.0.1
在通过dbca建库后,有两个控制文件,再添加一个控制文件
1、查看controlfile信息
[oracle@aix227:/home/oracle]$sqlplus '/as sysdba'
SQL*Plus: Release 10.2.0.1.0 - Production on Wed Nov 19 11:15:45 2014
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
SQL> show parameter control
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_file_record_keep_time integer 7
control_files string /u01/app/oracle/oradata/prod/c
ontrol01.ctl, /u01/app/oracle/
oradata/prod/control02.ctl
2、添加新的控制文件
文件存储采用的是raw,建立符号链接文件,易于管理。
[oracle@aix227:/home/oracle]$ls -l /u01/app/oracle/oradata/prod
total 0
lrwxrwxrwx 1 oracle oinstall 16 Nov 18 16:14 control01.ctl -> /dev/rcontrol1_1
lrwxrwxrwx 1 oracle oinstall 16 Nov 18 16:14 control02.ctl -> /dev/rcontrol2_2
lrwxrwxrwx 1 oracle oinstall 16 Nov 18 16:14 control03.ctl -> /dev/rcontrol3_3
lrwxrwxrwx 1 oracle oinstall 13 Nov 18 16:14 example01.dbf -> /dev/rexample

lrwxrwxrwx 1 oracle oinstall 13 Nov 18 16:14 log12.log -> /dev/rredo1_2
lrwxrwxrwx 1 oracle oinstall 12 Nov 18 16:14 spfile01 -> /dev/rspfile
lrwxrwxrwx 1 oracle oinstall 12 Nov 18 16:14 sysaux01.dbf -> /dev/rsysaux
lrwxrwxrwx 1 oracle oinstall 12 Nov 18 16:14 system01.dbf -> /dev/rsystem
lrwxrwxrwx 1 oracle oinstall 10 Nov 18 16:14 temp01.dbf -> /dev/rtemp
lrwxrwxrwx 1 oracle oinstall 14 Nov 18 16:14 undotbs01.dbf -> /dev/rundotbs1
lrwxrwxrwx 1 oracle oinstall 11 Nov 18 16:14 users01.dbf -> /dev/rusers
SQL> show parameter spfile;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string /u01/app/oracle/oradata/prod/s
pfile01
SQL> alter system set control_files=

System altered.
SQL> startup force nomount;
ORACLE instance started.

SQL> alter database mount;
alter database mount
*
ERROR at line 1:
ORA-00205: error in identifying control file, check alert log for more info
查看告警日志,无法识别control03.ctl文件!
3、复制RAW(controlfile)
SQL> shutdown abort;
ORACLE instance shut down.
[oracle@aix227:/home/oracle]$dd if=/dev/rcontrol1_1 of=/dev/rcontrol3_3 bs=1024k
64+0 records in
64+0 records out
4、重新启动数据库
[oracle@aix227:/home/oracle]$sqlplus '/as sysdba'
SQL*Plus: Release 10.2.0.1.0 - Production on Wed Nov 19 11:26:21 2014
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Connected to an idle instance.
SQL> startup mount;
ORACLE instance started.
Total System Global Area 977272832 bytes
Fixed Size 2025592 bytes
Variable Size 255854472 bytes
Database Buffers 713031680 bytes
Redo Buffers 6361088 bytes
Database mounted.
SQL> select name from v$controlfile;
NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/prod/control01.ctl
/u01/app/oracle/oradata/prod/control02.ctl
/u01/app/oracle/oradata/prod/control03.ctl
SQL> alter database open;
Database altered.
@至此,contolfile多元化成功!
