"/boot" partition doesn't have to be use LVM because 100MB is enough for it.
But do not use LVM for any shared disks like CSS, OCR or ASM disks.
On x86 and Itanium systems, although Red Hat Enterprise Linux 3 and SUSE Linux Enterprise Server provide a Logical Volume Manager (LVM), this LVM is not cluster-aware. For this reason, Oracle does not support the use of logical volumes with RAC on x86 and Itanium systems for either Oracle Clusterware or database files.

Software Settings:
When the Software Selection and System Tasks screen appear, select the C/C++ Compiler and Tools (must have) and Oracle Server Base (not mandatory).
Use the "Search" function, the following software/package are also needed to be installed:
Openmotif
mc (optional)
readline-devel (required if you want to use rlwrap)
sysstat
setarch
In this example, "orarun" package is not installed.
--------------------------------------------------------------------------------------------
Add configurations to the first SuSE linux node (sles101)
before cloning the Second node
--------------------------------------------------------------------------------------------
1. Edit /etc/hosts, and comment out or remove the line that maps the IP address 127.0.0.2 to the systems fully qualified hostname.
127.0.0.1 localhost
172.16.2.145 sles101.test.com sles101
172.16.2.146 sles102.test.com sles102
192.168.235.145 sles101-priv.test.com sles101-priv
192.168.235.146 sles102-priv.test.com sles102-priv
172.16.2.147 sles101-vip.test.com sles101-vip
172.16.2.148 sles102-vip.test.com sles102-vip
2. Edit /etc/SuSE-Release, change version number from 10 to 9.
$ cat /etc/SuSE-release
SUSE Linux Enterprise Server 9 (i586)
VERSION = 9
[It can be reverted back after Oracle 10g RAC has been installed.]
3. Edit /etc/sysctl.conf
$ cat /etc/sysctl.conf
# Disable response to broadcasts.
# You don't want yourself becoming a Smurf amplifier.
net.ipv4.icmp_echo_ignore_broadcasts = 1
IXDBA.NET技术社区
# enable route verification on all interfaces
net.ipv4.conf.all.rp_filter = 1
# enable ipV6 forwarding
#net.ipv6.conf.all.forwarding = 1
# Controls IP packet forwarding
net.ipv4.ip_forward = 0
# Controls the System Request debugging functionality of the kernel
kernel.sysrq = 1
#controls whether core dumps will append the PID to the core filename.
#Useful for debugging multi-threaded applications.
kernel.core_uses_pid = 1
# Oracle recommended kernel parameters
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 256 32000 100 128
kernel.msgmnb = 65535
kernel.msgmni = 2878
fs.file-max = 131072
net.ipv4.ip_local_port_range = 1024 65535
net.core.rmem_max = 262144
net.core.wmem_max = 262144
net.core.rmem_default = 262144
net.core.wmem_default = 262144
4. Edit /etc/pam.d/login, and add the following line (will be added automatically if "orarun" rmp package is installed)
session required pam_limits.so
5. Add "oracle" user and "dba" group
#mkdir -p /u01/app
#groupadd -g 115 dba
#useradd -u 175 -g 115 -d /home/oracle -s /bin/bash -c "Oracle Software Owner" -p oracle oracle
#chown -R oracle:dba /u01
6. Create partitions on shared disks and configuring the raw devices
Use "fdisk" to create primary partitions on all shared disks (2x 500MB partitions "sdd1" and "sde1" for OCR and CSS, 4x 2GB for ASM disks - "sdf1-sdi1")
$ cat /etc/raw
# /etc/raw
# The format of this file is:
# raw<N>:<blockdev>
# this means: bind /dev/raw/raw1 to /dev/hdb1
raw1:sdd1 #this will be the css space
raw2:sde1 #this will be used as ocr space
raw3:sdf1 #for ASM disk member
raw4:sdg1
raw5:sdh1
raw6:sdi1
Run the following command to make sure all raw devices started.
$/usr/sbin/raw -qa
/dev/raw/raw1: bound to major 8, minor 49
/dev/raw/raw2: bound to major 8, minor 65
/dev/raw/raw3: bound to major 8, minor 81
/dev/raw/raw4: bound to major 8, minor 97
/dev/raw/raw5: bound to major 8, minor 113
/dev/raw/raw6: bound to major 8, minor 129
In case of any raw partition could not be bound, please check if there is the correct devices being created under "/dev/" directory, run "partprobe" to refresh. This could be happened when you created a primary partition on a shared disk of node1, but the new device is not displayed on the other node.
7. Create raw devices for OCR and CSS shared disks, and mounting points for ASM disks.
#mkdir -p /u02/oradata/asm
#mknod /u02/oradata/css c 162 1
#mknod /u02/oradata/ocr c 162 2
#mknod /u02/oradata/asm/lun1 c 162 3
#mknod /u02/oradata/asm/lun2 c 162 4
#mknod /u02/oradata/asm/lun3 c 162 5
#mknod /u02/oradata/asm/lun4 c 162 6
#chmod 660 /u02/oradata/css
#chmod 660 /u02/oradata/ocr
#chmod 660 /u02/oradata/asm/*
#chown oracle.dba /u02/oradata/css
#chown oracle.dba /u02/oradata/ocr
#chown oracle.dba /u02/oradata/asm/*
lun1-4 will be used as ASM disks for oracle data, after CRS and Database software is installed, run DBCA to configure ASM storage and add lun1-4 as members for the ASM disk groups. (If EMC storage will be used to provide the share disks, we can also create same character devices to link them.)
8. Login as "oracle" user and modify the enviroment file /home/oracle/.profile, see following example with some of useful aliases.
$ cat .profile
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=$ORACLE_BASE/product/10.2/db_1
ORACLE_SID=sles
ORA_CRS_HOME=$ORACLE_BASE/product/10.2/crs_1
export ORACLE_DB=sles
export ORACLE_BASE ORACLE_HOME ORACLE_SID ORA_CRS_HOME
export NLS_DATE_FORMAT='MM/DD/YYYY HH24:MI:SS'
export PS1='[`whoami`@${HOSTNAME} ${PWD}]\n$ '
PATH=$PATH:$ORACLE_HOME/bin
LD_LIBRARY_PATH=${LD_LIBRARY_PATH:+$LD_LIBRARY_PATH:}$ORACLE_HOME/lib:/lib:$ORACLE_HOME/ctx/lib
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib:$ORACLE_HOME/network/jlib
export AGENT_HOME PATH LD_LIBRARY_PATH CLASSPATH TNS_ADMIN
alias ASM='export ORACLE_SID=+ASM1'
alias dbn='export ORACLE_SID=sles1'
alias envora='env | grep ORA'
alias ssh2='ssh sles102'
alias crs='cd $ORA_CRS_HOME/bin'
alias cddb='cd $ORACLE_HOME/bin'
alias sysdba='sqlplus / as sysdba'
alias envora='env | grep ORA'
alias sqlplus='rlwrap sqlplus'
9. And don't forget to install vmware-tools (run from non-X Windows logon session)
# ./vmware-install.pl
