Normal 0 7.8 磅 0 2 false false false EN-US ZH-CN X-NONE1．  文件系统

   #fdisk /dev/sda  划分区sda2

   #mkdir /backup

   #mount /dev/sda2 /backup

2．  ASM

(1)     根据内核版本(uname -r)安装asm包

oracleasm-support-2.1.7-1.el5.ia64.rpm

oracleasmlib-2.0.4-1.el5.ia64.rpm

oracleasm-2.6.18-8.el5-2.0.4-1.el5.i686.rpm  (与内核版本有关)

(2)     确认selinux关闭

#vi  /etc/sysconfig/selinux  修改 selinux=disable

否则配置ASM会失败

(3)     配置ASM用户及版本信息

#/etc/init.d/oracleasm configure

输入用户和组名  (oracle ,oinstall)

(4)     创建ASM磁盘组

方法1：

1>创建文件

#dd if=/dev/zero f=/backup/oradata/asm/sdd1 bs=1M count=300

#dd if=/dev/zero f=/backup/oradata/asm/sdd2 bs=1M count=300

2>将文件虚拟成循环设备

#/sbin/losetup /dev/loop1 /backup/oradata/asm/sdd1

#/sbin/losetup /dev/loop2 /backup/oradata/asm/sdd2

3>创建asm磁盘组

#/etc/init.d/oracleasm createdisk  VOL1  /dev/loop1

#/etc/init.d/oracleasm createdisk  VOL2  /dev/loop2

方法2：

#fdisk /dev/sdb   新创建设备文件/dev/sdb1

#/etc/init.d/oracleasm createdisk  vol_sdb1  /dev/sdb1

方法3：

#fdisk  /dev/sdb 创建分区sdb2,sdb3,类型为8e(lvm);sdb5为正常类型

#vi /etc/sysconfig/rawdevices  添加：（其中sdb2已加入vgdata中）

/dev/raw/raw2  /dev/sdb2

/dev/raw/raw3  /dev/sdb3

/dev/raw/raw5  /dev/sdb5

#chkconfig rawdevices on

#partprobe

       #service rawdevices restart   重起raw服务，识别raw

       #raw –qa

       #raw /dev/raw/raw2 0 0 删除raw2

 

#vi /etc/rc.d/init.d/rawdevices  的start处的assign_raw下添加：

Sleep 3

Chown –R oracle:oinstall /dev/raw/

 

 

创建的磁盘组会在/dev/oracleasm/disks下生成。

(5)     设置ASM自启动

#vi /etc/rc.local  添加如下内容：

/sbin/losetup /dev/loop1 /backup/oradata/asm/sdd1

/sbin/losetup /dev/loop2 /backup/oradata/asm/sdd2

oracleasm scandisks

(6)     配置css服务

#/u01/db/bin/localconfig add

检查css服务

#more /etc/inittab

h1:35:respawn:/etc/init.d/init.cssd run >/dev/null 2>&1

#ps –ef|grep css

(7)     D

3．  裸设备(raw)

以下方法使用于redhat 5之后：

(1)     分区

#fdisk  /dev/sdc   分区sdc5-sdc15,sdc2（sdc5 200M，其余50M）

(2)     修改文件vi /etc/udev/rules.d/60-raw.rules

#添加映射关系及权限

ACTION=="add", KERNEL=="sdc5", RUN+="/bin/raw /dev/raw/raw6 %N"

KERNEL=="raw*", WNER="oracle", GROUP="dba", MODE="660"

(3)     新建立文件 dbca_raw.conf

system = /u01/oradata/raw/system

sysaux = /u01/oradata/raw/sysaux

undotbs1= /u01/oradata/raw/undotbs1

temp = /u01/oradata/raw/temp

users = /u01/oradata/raw/users

spfile = /u01/oradata/raw/spfile

control1 = /u01/oradata/raw/control01

control2 = /u01/oradata/raw/control02

control3 = /u01/oradata/raw/control03

redo1_1 = /u01/oradata/raw/redo01

redo1_2 = /u01/oradata/raw/redo02

redo1_2 = /u01/oradata/raw/redo03

(4)     建立链接

   #ln -s /dev/raw/raw6 /u01/oradata/raw/system

#ln -s /dev/raw/raw7 /u01/oradata/raw/sysaux

#ln -s /dev/raw/raw8 /u01/oradata/raw/undotbs1
