系统环境:
操作系统:RedHat EL5
Cluster: Oracle CRS 10.2.0.1.0
Oracle: Oracle 10.2.0.1.0
如图所示:RAC 系统架构
一、操作系统环境
1、网络配置(在所有节点)

# Do not remove the following line, or various programs
# that require network functionality will fail.127.0.0.1 localhost
192.168.8.21 node1 ;节点1主机名
192.168.8.23 node1-vip
10.10.10.21 node1-priv
192.168.8.22 node2 ;节点2主机名
192.168.8.24 node2-vip
10.10.10.22 node2-priv
|
2、共享磁盘配置(在所有节点)
对于Oracle 10g RAC,OCR和VOTE DISK、DataBase需建立在共享存储设备上;OCR和VOTE DISK必须以raw的方式管理,而存放DataBase的磁盘必须以ASM的方式管理。
[[email protected] ~]# fdisk -l

node1 作为ntp server ,node2 作为ntp client配置如下:node1:[[email protected] ~]# chkconfig --list |grep time daytime-dgram: off
daytime-stream: off
time-dgram: off
time-stream: off
[[email protected] ~]# chkconfig time-dgram on
[[email protected] ~]# chkconfig time-stream on
[[email protected] ~]# chkconfig ntpd on
[[email protected] ~]# chkconfig xinetd on
[[email protected] ~]# service ntpd startStarting ntpd: [ OK ]node2:[[email protected] asm]# crontab -l0-59/1 * * * * /usr/bin/rdate -s 192.168.8.21 >/dev/null 2>&1
