linux下Oracle11g RAC搭建（四）

三、配置共享存储 

配置ASM管理准备

1）OCRDISK ：存储CRS资源配置信息

2）VOTEDISK：仲裁盘，记录节点状态

3）DataDisk：存放datafile、controlfile、redologfile、spfile等

4）RecoveryArea：存放flashbackdatabase log、archivelog、rmanbackup等

安装asm软件包

分别在node1和node2安装

node1下：

[root@node1 ~]# cd /soft

[root@node1 soft]# ls

asm linux_11gR2_database_1of2.zip linux_11gR2_database_2of2.zip linux_11gR2_grid.zip

[root@node1 asm]# cd asm

[root@node1 asm]# ls

oracleasm-2.6.18-194.el5-2.0.5-1.el5.i686.rpm

oracleasmlib-2.0.4-1.el5.i386.rpm

oracleasm-support-2.1.3-1.el5.i386.rpm

注意和内核版本的匹配

 说明：

1、查看到asm软件包版本2.6.18-194.el5，系统内核版本2.6.18-194.el5，两者匹配，可以继续安装；

2、i386代表32位。

[root@node1 asm]# uname-a  或uname -r

//检查系统内核版本是否和asm版本相同

Linux node1 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:43 EDT 2010 i686 i686i386 GNU/Linux

node1下安装软件包

[root@node1 asm]# rpm -ivh *

//安装3个软件包，i-install，v-安装过程，h-显示安装信息，*-全部软件包

 [root@node1 asm]# rpm -qa |grep asm    //查看安装完成的信息

node2下安装软件包

node2下：

[root@node1 /]# scp/soft/asm/* node2:/home/oracle/

 //把asm下的软件包从node1拷贝到node2下面

或[root@node1 soft]# scp -r asm  node2:/home/oracle/

[root@node2 ~]#cd/home/oracle

[root@node2 oracle]# ls

oracleasm-2.6.18-194.el5-2.0.5-1.el5.i686.rpm

oracleasmlib-2.0.4-1.el5.i386.rpm

oracleasm-support-2.1.3-1.el5.i386.rpm

[root@node2 asm]# rpm -ivh *

1)在共享阵列上建立分区

在node1分区，完成后在node2查看

OCR+VOTE盘：3个1G

DATABASE 盘：2个5G

RECOVERY盘：2个4G

3个1G的为OCR_VOTE1盘      其中两个为镜像

2个5G的为ASM_DATA1盘     其中一个为镜像

2个4G的为ASM_RCY1盘        其中一个为镜像

Command (m for help): p                       //查看分区结果

 Command (m for help): w                       //保存退出

 [root@node1 ~]# fdisk -l                              //分区结果

2)创建asm盘

配置asm 磁盘（node1、node2）

node1上

[root@node1 soft]# serviceoracleasm configure

Configuring the Oracle ASM library driver.

This will configure the on-boot properties of theOracle ASM library

driver.  Thefollowing 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 <ENTER> without typing an

answer will keep that current value.  Ctrl-C will abort.

Default user to own the driver interface []: grid

Default group to own the driver interface []: asmadmin

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

Scan for Oracle ASM disks on boot (y/n) [y]:

Writing Oracle ASM library driver configuration: done

Initializing the Oracle ASMLib driver: [  OK  ]

Scanning the system for Oracle ASMLib disks: [  OK  ]

node2上

[root@node2 asm]# serviceoracleasm configure

Configuring the Oracle ASM library driver.

This will configure the on-boot properties of theOracle ASM library

driver.  Thefollowing 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 <ENTER> without typing an

answer will keep that current value.  Ctrl-C will abort.

Default user to own the driver interface []: grid

Default group to own the driver interface []: asmadmin

Initializing the Oracle ASMLib driver: [  OK  ]

Scanning the system for Oracle ASMLib disks: [  OK  ]

建立asm 磁盘（node1）

在node1上

[root@node1 soft]# serviceoracleasm

Usage: /etc/init.d/oracleasm{start|stop|restart|enable|disable|configure|createdisk|deletedisk|querydisk|listdisks|scandisks|status}

[root@node1 soft]# serviceoracleasm createdisk OCR_VOTE1 /dev/sdc1 

//磁盘名用大写

Marking disk "OCR_VOTE1" as an ASM disk:[  OK ]

[root@node1 soft]# serviceoracleasm createdisk OCR_VOTE2 /dev/sdc2

Marking disk "OCR_VOTE2" as an ASM disk:[  OK ]

[root@node1 soft]# serviceoracleasm createdisk OCR_VOTE3 /dev/sdc3

Marking disk "OCR_VOTE3" as an ASM disk:[  OK ]

[root@node1 soft]# serviceoracleasm createdisk ASM_DATA1  /dev/sdc5

Marking disk "ASM_DATA1" as an ASM disk:[  OK ]

[root@node1 soft]# serviceoracleasm createdisk ASM_DATA2  /dev/sdc6

Marking disk "ASM_DATA2" as an ASM disk:[  OK ]

[root@node1 soft]# serviceoracleasm createdisk ASM_RCY1   /dev/sdc7

Marking disk "ASM_RCY1" as an ASM disk:[  OK ]

[root@node1 soft]# serviceoracleasm createdisk ASM_RCY2   /dev/sdc8

Marking disk "ASM_RCY2" as an ASM disk:[  OK ]

[root@node1 soft]# serviceoracleasm listdisks       //查看asm创建结果

ASM_DATA1

ASM_DATA2

ASM_RCY1

ASM_RCY2

OCR_VOTE1

OCR_VOTE2      

OCR_VOTE3

验证ASM磁盘信息（node2）

在node2节点扫描出磁盘，查看共享磁盘信息

[root@node2 asm]# serviceoracleasm scandisks      //扫描共享磁盘asm

Scanning the system for Oracle ASMLib disks: [  OK  ]

[root@node2 asm]# serviceoracleasm listdisks        //查看共享盘信息

ASM_DATA1

ASM_DATA2

ASM_RCY1

ASM_RCY2

OCR_VOTE1

OCR_VOTE2

OCR_VOTE3
