10G RAC中将controlfile进行多元存放（非OMF格式）
1,确定control_files参数
SQL> show parameter control_files
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_files string +DATA/jtods/control01.ctl, +DA
TA/jtods/control02.ctl, +DATA/
jtods/control03.ctl
2,更新spfile中的control_files参数
SQL>ALTER SYSTEM SETcontrol_files='+DATA/JTODS/control01.ctl','+DATA/JTODS/control02.ctl','+DATA/JTODS/control03.ctl','+RECOVERY/JTODS/controlfile/control04.ctl';
注意control_files的格式,不同的目录使用引号和逗号隔开.
3,关闭2个节点的实例
srvctl stop database -d JTODS
4,启动节点1,JTODS1至NOMOUNT状态
SQL>STARTUP NOMOUNT;
SQL>show parameter control_file
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_files string +DATA/jtods/control01.ctl, +DA
TA/jtods/control02.ctl, +DATA/
jtods/control03.ctl,+RECOVERY
/jtods/controlfile/control04.c
tl
说明参数已经生效.
5,RMAN从当前的控制文件恢至新的目录
[oracle@vmrac2 ~]$ rman target /
Recovery Manager: Release 10.2.0.5.0 - Production on Thu Jan 5 11:25:13
Copyright (c) 1982, , Oracle. All rights reserved.
connected to target database: JTODS (not mounted)
RMAN> restore controlfile from '+DATA/JTODS/control01.ctl';
Starting restore at 05-JAN-12
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=148 instance=JTODS2 devtype=DISK
channel ORA_DISK_1: copied control file copy
output filename=+DATA/jtods/control01.ctl
output filename=+DATA/jtods/control02.ctl
output filename=+DATA/jtods/control03.ctl
output filename=+RECOVERY/jtods/controlfile/control04.ctl
Finished restore at 05-JAN-12
6,关闭当前这个实例,重新启动两个节点的实例.
SQL>shutdown immediate
srvctl start database -d JTODS
7,确认修改已经生效.
服务已经正常启动,却控制文件已经存放在了定义的所有目录.
Oracle 10g ASM中控制文件多路（OMF格式）
1，当前控制文件
SQL> show parameter control
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_file_record_keep_time integer 7
control_files string +DATADG/prod/controlfile/curre
nt.263.81717, +FRADG/prod/
controlfile/current.256.817172
021, +DATADG/prod/controlfile/
current.261.819294085
2，关闭数据库实例（2个实例都关闭）
srvctl stop database -d PROD -o immediate
3，RMAN恢复控制文件（在一个节点执行即可）
RMAN> restore controlfile to '+FRADG' from '+DATADG/prod/controlfile/current.263.81717';
Starting restore at -07-02 09:04:43
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=144 instance=prod1 device type=DISK
channel ORA_DISK_1: copied control file copy
Finished restore at -07-02 09:04:46
4，ASMCMD中找到新恢复的控制文件
ASMCMD> pwd
+FRADG/PROD/CONTROLFILE
ASMCMD> ls -l
Type Redund Striped Time Sys Name
CONTROLFILE UNPROT FINE JUL 02 08:00:00 Y current.256.81717
CONTROLFILE UNPROT FINE JUL 02 09:00:00 Y current.420.819709485
确定current.420.819709485为增加的控制文件。
5，SQLPLUS中将其与原控制文件一起更新至spfile的control_file参数。
SQL> alter system set control_files='+FRADG/PROD/CONTROLFILE/current.420.819709485','+DATADG/prod/controlfile/current.263.81717','+FRADG/prod/controlfile/current.256.81717','+DATADG/prod/controlfile/current.261.819294085' scope=spfile;
System altered.
6，关闭数据库，重启。（1个节点上执行）
SQL>shutdown immediate
srvctl start database -d PROD
