Oracle asmlib 安装配置及磁盘创建，目前只有linux 操作系统上有asmlib 包，其他的系统暂时还没有。asmlib 简化磁盘管理，取代原

一、 Oracle asmlib 安装

在oracle.com 上下载合适的驱动程序，版本和操作系统的内核要一致。

目前只有linux 操作系统上有asmlib 包，其他的系统暂时还没有。asmlib 简化磁盘管理，取代原来我们在linux 上常用rawdevices 服务。

根据uname –r 检测结果，下载的驱动程序包名称与其一致。务必！！！

[root@db2 ~]# uname -r

2.6.18-238.el5

这里我最初下载包是2.6.18-238.12.1.el5 ，安装后初始化配置时失败。后来又找到一个oracleasm-2.6.18-238.el5-2.0.5-1.el5 的安装包，安装成功后才成功。

[root@db2 ~]# rpm -qa |grep asm

oracleasm-2.6.18-238.el5-2.0.5-1.el5

oracleasmlib-2.0.4-1.el5

oracleasm-2.6.18-238.12.1.el5-2.0.5-1.el5

oracleasm-support-2.1.7-1.el5

oracleasm-2.6.18-238.12.1.el5-debuginfo-2.0.5-1.el5

真正需要安装的asmlib 包如下：

oracleasm-support-version.arch.rpm

oracleasm-kernel-version.arch.rpm

oracleasmlib- version .arch.rpm

二、Oracle asmlib 配置
在软件包安装以后，需要配置才能使其生效。

[root@db2 ~]# oracleasm configure

执行结果如下：

Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting without typing an
answer will keep that current value. Ctrl-C will abort.

Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [y]:
Fix permissions of Oracle ASM disks on boot (y/n) [y]:
Writing Oracle ASM library driver configuration: [ OK ]
Scanning system for ASM disks: [ OK ]

这个脚本执行完成了四大任务。

1 、创建了配置文件/etc/sysconfig/oracleasm

2 、创建了挂载点/dev/oracleasm

3 、加载oracleasm 内核模块

4 、挂载ASM 函数驱动文件系统
