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

[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

[root@node1 ~]# fdisk -l
