10g rac安装注意事项

1、配置ip地址不要忘记网关
DEVICE=eth0
BOOTPROTO=none
BROADCAST=192.168.100.255
HWADDR=00:0C:29:28:8F:AC
IPADDR=192.168.100.101
NETMASK=255.255.255.0
NETWORK=192.168.100.0
ONBOOT=yes
TYPE=Ethernet
GATEWAY=192.168.100.1

2、域名解析不要忘记了localhost
127.0.0.1 localhost
192.168.100.101 node1
192.168.100.102 node2
192.168.100.201 node1-vip
192.168.100.202 node2-vip
10.10.17.221 node1-priv
10.10.17.222 node2-priv

3、重新安装处理
rm -f /etc/init.d/init.cssd
rm -f /etc/init.d/init.crs
rm -f /etc/init.d/init.crsd
rm -f /etc/init.d/init.evmd
rm -f /etc/rc2.d/K96init.crs
rm -f /etc/rc2.d/S96init.crs
rm -f /etc/rc3.d/K96init.crs
rm -f /etc/rc3.d/S96init.crs
rm -f /etc/rc5.d/K96init.crs
rm -f /etc/rc5.d/S96init.crs
rm -rf /etc/oracle/scls_scr
rm -f /etc/inittab.crs
rm -rf /u01/oraInventory
rm -rf /u01/app/crs
rm -rf /etc/ora*
rm -rf /etc/init.d/init.*
rm -f /usr/local/bin/*
rm -rf /opt/ORCLfmap
rm -rf /opt/oracle/admin
dd if=/dev/null of=/dev/raw/raw2 bs=209715200 count=1
dd if=/dev/null of=/dev/raw/raw1 bs=104857600 count=1
dd if=/dev/null of=/dev/raw/raw3 bs=1232896 count=1000
dd if=/dev/null of=/dev/raw/raw4 bs=1232896 count=1000
Note：dd操作效果不好，可以在执行root.sh到Startup will be queued to init within 90 seconds.挂起后，执行$CRS_HOME/install/rootdeinstall.sh，然后再执行root.sh

4、因内网ip地址不能被自动添加到vip中处理
出现现象：
Checking existence of VIP node application (required)
Check failed.
Check failed on nodes:
node2,node1
解决：使用root账户运行图画界面vipca，手工添加vip的域名和地址

5、remote_listener和tns名称一致
show parameter remote_listener
NAME TYPE VALUE
———————————— ———– ————-
remote_listener string LISTENERS_XFF
tnsnames.ora

LISTENERS_XFF =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.100.201)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.100.202)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = xff)
)
)

6、各个节点时间一致
选择一种一个为时间参考节点
[root@node1 bin]# cat /etc/ntp.conf
server 127.127.1.0
fudge 127.127.1.0 stratum 11
driftfile /var/lib/ntp/drift
broadcastdelay 0.008

其他节点同步该时间
[root@node2 bin]# crontab -l
*/15 * * * * ntpdate node1

均开启ntpd服务
service ntpd start
chkconfig ntpd on
