Oracle 10203 RAC Environment Add new node (i) Preparation process

Briefly describe the process of adding a node in the Oracle 10203 for Solaris SPARC Dual-node environment. Shared storage is already configured on a third node, which focuses on the configuration on the operating system and on Oracle.

This article describes the preparation process.

The first is to adjust the IP address of the host to the RAC server IP address for easy management. Modify the destination host IP address to 172.25.198.226.

# ifconfig CE0 172.25.198.226 netmask 255.255.0.0 broadcast 172.25.255.255

Then modify the IP address in the/etc/hosts file.

The host name is also modified to the supporting hostname information RACNODE3:

# hostname

Supingsol

# hostname Racnode3

After using hostname to set the hostname, you also need to modify the/etc/hosts,/ect/nodename,/etc/hostname.ce0,/etc/net/ticlts/hosts,/etc/net/ticots/hosts, /etc/net/ticotsord/hosts these 6 files:

# more/etc/hosts

#

# Internet Host Table

#

127.0.0.1 localhost

172.25.198.226 Racnode3 Loghost

192.168.192.109 RW

# More/etc/nodename

Racnode3

# MORE/ETC/HOSTNAME.CE0
