Oracle版本:Oracle 11g

1、确定自己的Linux版本:

[root@localhost ~]#uname -r

 2.6.32-431.el6.x86_64

 2.6.32-431.el6.x86_64,即Linux 6

2、安装Oracleasm Kernel:

 

[root@localhost ~]# yum install kmod-oracleasm

 

3下载两个安装包:oracleasmliboracleasm-support

[root@localhost ~]#wget http://oss.oracle.com/projects/oracleasm-support/dist/files/RPMS/rhel6/amd64/2.1.8/oracleasm-support-2.1.8-1.el6.x86_64.rpm

[root@localhost ~]#wget http://download.oracle.com/otn_software/asmlib/oracleasmlib-2.0.4-1.el6.x86_64.rpm

 

4安装这两个包:

 

[root@localhost ~]#rpm -ivh oracleasm*

 

5、配置:

[root@localhost ~]#su oracle

[root@localhost ~]#/etc/init.d/oracleasm configure

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) [n]: y

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

Writing Oracle ASM library driver configuration [ OK ]

Creating /dev/oracleasm mount point [ OK ]

Loading module "oracleasm" [ OK ]

Mounting ASMlib driver filesystem [ OK ]

Scanning system for ASM disks [ OK ]

如果想关闭这个ASM磁盘,可以这样配置:

[root@ca-test1 /]# /etc/init.d/oracleasm disable

Writing Oracle ASM library driver configuration [ OK ]

Unmounting ASMlib driver filesystem [ OK ]

Unloading module "oracleasm" [ OK ]

 

[root@ca-test1 /]# /etc/init.d/oracleasm enable

Writing Oracle ASM library driver configuration [ OK ]

Loading module "oracleasm" [ OK ]

Mounting ASMlib driver filesystem [ OK ]

Scanning system for ASM disks [ OK ]

6、ASM准备一块硬盘空间:

首先可以使用fdisk -l命令查看分区,

我这里为ASM准备了一块还没有分区的硬盘,

使用fdisk -l命令看到这块硬盘叫sdc,然后我们开始给这块硬盘分区:

[root@localhost ~]# fdisk /dev/sdc

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Building a new DOS disklabel with disk identifier 0x3c1761b2.

Changes will remain in memory only, until you decide to write them.

After that, of course, the previous content won‘t be recoverable.

 

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

 

WARNING: DOS-compatible mode is deprecated. It‘s strongly recommended to

switch off the mode (command ‘c‘) and change display units to

sectors (command ‘u‘).

 

Command (m for help): m

Command action

a toggle a bootable flag

b edit bsd disklabel

c toggle the dos compatibility flag

d delete a partition

l list known partition types

m print this menu

n add a new partition(创建新分区)

o create a new empty DOS partition table

p print the partition table

q quit without saving changes

s create a new empty Sun disklabel

t change a partition‘s system id

u change display/entry units

v verify the partition table

w write table to disk and exit

x extra functionality (experts only)

 

Command (m for help): n

Command action

e extended

p primary partition (1-4)

因为ASM要求必须是主分区或逻辑分区所以只能选p:

Command (m for help): p

Partition number (1-4): 2

First cylinder (1-121601, default 1):

Using default value 1

Last cylinder, +cylinders or +size{K,M,G} (1-121601, default 121601):

Using default value 121601

再次执行fdisk -l命令查看分区:

Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes

255 heads, 63 sectors/track, 121601 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x881f3ea8

 

Device Boot Start End Blocks Id System

/dev/sdc2 1 121601 976760001 83 Linux

7、将硬盘空间分配给ASM:

 

查看磁盘组:

[root@ca-test1 /]# /etc/init.d/oracleasm listdisks

VOL1

新建一个磁盘组VOL2并分配给ASM:

[root@ca-test1 /]# /etc/init.d/oracleasm createdisk VOL2 /dev/sdc2

Creating Oracle ASM disk "VOL2" [ OK ]
