oracle磁盘组实例启动,配置使用ASM磁盘组方案

AS4 下安装Oracle 10g ASM

背景:

环境:

Linux AS4

Oracle 10.2.0.1

ASM

配置步骤:

1、安装Oracle ASMLib

需要的安装包

asmlib

asm-support

asm-kernel

asm-smp-kernel(多process版本)

下载地址:http://www.doczj.com/doc/27da8989a0116c175f0e4801.html/technology/software/tech/linux/asmlib/rhel4.html

uname -a

安装3个软件包:

# rpm -Uvh oracleasm-support-2.1.3-1.el4.i386.rpm

# rpm -Uvh oracleasm-2.6.9-55.ELsmp-2.0.3-1.i686.rpm

# rpm -Uvh oracleasmlib-2.0.4-1.el4.i386.rpm

2、配置ASMLib

# /etc/init.d/oracleasm configure

Default user to own the driver interface [oracle]: oracle

Default group to own the driver interface [oinstall]: oinstall

Start Oracle ASM library driver on boot (y/n) [y]: y

Fix permissions of Oracle ASM disks on boot (y/n) [y]: y

Writing Oracle ASM library driver configuration: [ OK ]

Loading module "oracleasm": [ OK ]

Mounting ASMlib driver filesystem: [ OK ]

Scanning system for ASM disks: [ OK ]

以上操作将加载oracleasm.o驱动,并且mount上ASM文件系统,同时我们可以通过以下命令来手工的卸载和加载ASMLib

#/etc/init.d/oracleasm disable //出错检查/var/log/messages文件,确认需要更新的内核版本#/etc/init.d/oracleasm enable

添加init文件使系统启动时自动加载ASMLib

$su - root

#cd /etc/rc3.d

#ln -s ../init.d/oracleasm S99oracleasm
