Pre-Installation Tasks
A.
Network configuration
This part is done manually. Here is the files on node1 as an example:
/etc/hosts
127.0.0.1 localhost
# node1
192.168.1.64 rac1 rac1.abc.com loghost
10.10.10.1 rac1-priv rac1-priv.abc.com
192.168.1.69 rac1-vip rac1-vip.abc.com
# node2
192.168.1.77 rac2 rac2.abc.com
10.10.10.2 rac2-priv rac2-priv.abc.com
192.168.1.76 rac2-vip rac2-vip.abc.com
/etc/inet/netmasks
192.168.0.0 255.255.255.0
10.10.10.0 255.255.255.0
/etc/hostname.hme0
rac1
/etc/hostname.le0
10.10.10.1
/etc/defaultrouter
192.168.1.1
/etc/hosts.allow
ALL: 192.168.1. 127.0.0.1 10.
Run these commands to bring up the network interface le0 and test it.
# chown root:root /etc/hostname.le0
# ifconfig le0 plumb
# ifconfig le0 10.10.10.1 netmask 255.255.255.0 up
# ifconfig -a
lo0: flags=1000849 mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
hme0: flags=1000843 mtu 1500 index 2
inet 192.168.1.64 netmask ffffff00 broadcast 192.168.1.255
ether 8:0:20:82:47:d4
le0: flags=1000843 mtu 1500 index 3
inet 10.10.10.1 netmask ffffff00 broadcast 10.10.10.255
ether 8:0:20:82:47:d4
#
To check the network setup, run the CVU now or run it after all tasks is done.
The command is:
/ora10.dvd2/clusterware/cluvfy/runcluvfy.sh comp nodecon -n rac1,rac2 -verbose
B.
Other pre-installation tasks except Configuring SSH
A shell script is created for doing most of the tasks: pre.install.ora10.conf.sh
The script will do the pre-installation tasks of the clusterware and most of the
pre-installation tasks of the Oracle database. It is only to run on a new installation
of a Solaris 9 system. Run this script on both nodes as root.

Check the current values of Kernel Parameters after rebooted the system.
Login as user oracle, and then run the commands on all nodes:
/usr/sbin/sysdef | grep SEM
/usr/sbin/sysdef | grep SHM
Check the env variables of oracle account for installing the Clusterware:
$ env | grep ORACLE
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/crs/oracle/product/10/crs

C.
Configuring SSH on All Cluster Nodes
The ssh of Solaris9 is a Sun_SSH_1.1, which has a bug. Here is the discussion about it:
The instructions of configuring SSH in doc 2 is based on OpenSSH V.3.x. The doc 2 also
points out that Oracle NetCA and DBCA require scp and ssh to be located in the path
/usr/local/bin. For these reasons, I choose to install openssh-4.3p2-sol9-sparc-local
on the two nodes. Also need to set the value of "StrictModes" to "no" in
/usr/local/etc/sshd_config, or the ssh will prompt for a pasword even all configuration
tasks of shh has done.
Two scripts are created for configuring ssh. Here is the instruction on how to run them:
1. Put ssh.conf1.ksh under the home directory of user oracle on all nodes.
2. Run ssh.conf1.ksh on node1.
3. Make changes of ssh.conf1.ksh on node2 and then run it.
4. Run ssh.conf2.ksh on node1.
5. Run command on all nodes: chmod 600 .ssh/authorized_keys
6. Test the configuration on all nodes. The command is: ssh node1 [node2] date
ssh.conf1.ksh
------------------------------------------------------------
#!/bin/ksh
# Run this script as user oracle on node1, and then on node2.
# Make sure the package ssh is installed under /usr/local.
# Written by 071906
# Put the hostname of the two nodes below
node1=rac1
node2=rac2
sc_name=ssh.conf1.ksh

key_dir=${home_dir}/.ssh
ssh_base=/usr/local/bin
echo ================================================================

D.
Configuring clusterware and database storage (ASM installation)
After installed the host adapter(X1057A) on both nodes, run command "format" on them
to make sure the shared disks have the same controller number on both nodes.
Format the disks on node1. For disks used by ASM, create a single whole-disk slice,
starting at cylinder 1, or the ASM will NOT recognize these disks as ASM candidates.
