10g RAC Installation Considerations

1, configure the IP address do not forget the gateway
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, Domain name analysis do not forget the 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, reinstall processing
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 operation effect is not good, can be executed root.sh to the startup will is queued to init within seconds. When suspended, execute $crs_home/install/ Rootdeinstall.sh, and then execute root.sh

4, because the intranet IP address can not be automatically added to the VIP processing
The phenomenon occurs:
Checking Existence of VIP node application (required)
Check failed.
Check failed on nodes:
Node2,node1
Resolution: Use the root account to run the drawing interface VIPCA, manually add the VIP domain name and address

5, Remote_listener and TNS name consistent
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, each node time consistent
Select one for the time reference node
[Email protected] 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

Other nodes synchronize the time
[Email protected] bin]# crontab-l
*/15 * * * * ntpdate Node1

All open NTPD Services
Service NTPD Start
Chkconfig ntpd on
