Determine your current kernel.
uname -rm
2.6.18-164.el5 x86
(This is my Linux Kernel Version, your might be different, download software related to your kernel)
Check if following packages are installed on your machine otherwise install download a version of package which is compatible with your Operating system version and Kernel.
[root@rac1 ~]# rpm -qa | grep oracleasm*
oracleasm-2.6.18-238.el5debug-2.0.5-1.el5
oracleasm-2.6.18-238.el5-2.0.5-1.el5
oracleasm-support-2.1.4-1.el5
[root@rac1 ~]# rpm -qa | grep kernel-debug*
kernel-debug-2.6.18-238.el5
If you are using Oracle Enterprise Linux then you can find these package in Linux Installation CD
# For OEL, use relevant versions of the following packages from your media.
rpm -Uvh oracleasm-2.6.18-194.el5-2.0.5-1.el5.x86_64.rpm \
oracleasm-support-2.1.3-1.el5.x86_64.rpm \
oracleasm-2.6.18-238.el5debug-2.0.5-1.el5
Oracle Installation Prerequisites
Perform the following steps whilst logged into the RAC1 virtual machine as the root user.
Make sure the shared memory filesystem is big enough for Automatic Memory Manager to work.
# umount tmpfs
# mount -t tmpfs shmfs -o size=1500m /dev/shm
Make the setting permanent by amending the "tmpfs" setting of the "/etc/fstab" file to look like this.
tmpfs /dev/shm tmpfs size=1500m 0 0
If you are not using DNS, the "/etc/hosts" file must contain the following information.
127.0.0.1 localhost
# Public
132.35.21.177 rac1.rrm.gov rac1
132.35.21.178 rac2.rrm.gov rac2
# Private
10.10.10.1 rac1-priv.rrm.gov rac1-priv
10.10.10.2 rac2-priv.rrm.gov rac2-priv
# Virtual
132.35.21.187 rac1-vip.rrm.gov rac1-vip
132.35.21.188 rac2-vip.rrm.gov rac2-vip
# Scan
132.35.21.198 rac-scan.rrm.gov rac-scan
Note. The SCAN address should not really be defined in the hosts file. Instead is should be defined on the DNS to round-robin between 3 addresses on the same subnet as the public IPs. For this installation, we will compromise and use the hosts file. This approach will not work with 11.2.0.2 onwards. Instead you should use the DNS.
If you are using DNS, then only the first line need be present in the "/etc/hosts" file.
Add or amend the following lines to the "/etc/sysctl.conf" file.
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 1054504960
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048586
Run the following command to change the current kernel parameters.
/sbin/sysctl -p
Add the following lines to the "/etc/security/limits.conf" file.
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
Add the following lines to the "/etc/pam.d/login" file, if it does not already exist.
session required pam_limits.so
Disable secure linux by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.
SELINUX=disabled
Alternatively, this alteration can be done using the GUI tool (System > Administration > Security Level and Firewall). Click on the SELinux tab and disable the feature.
deconfigure NTP.
# service ntpd stop
Shutting down ntpd: [ OK ]
# chkconfig ntpd off
# mv /etc/ntp.conf /etc/ntp.conf.org
# rm /var/run/ntpd.pid
Create the new groups and users.
groupadd -g 1000 oinstall
groupadd -g 1200 dba
useradd -u 1100 -g oinstall -G dba oracle
passwd oracle
Create the directories in which the Oracle software will be installed.
mkdir -p /u01/app/11.2.0/grid
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01/
Login as the oracle user and add the following lines at the end of the ".bash_profile" file.
# User specific environment and startup programs
#oracle settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
GRID_HOME=/u01/app/11.2.0/grid; export GRID_HOME
PATH=$PATH:$HOME/bin:/usr/sbin:$ORACLE_HOME/bin:$GRID_HOME/bin export PATH
ORACLE_HOSTNAME=rac1.rrm.gov; export ORACLE_HOSTNAME
ORACLE_UNQNAME=RAC; export ORACLE_UNQNAME
ORACLE_SID=RAC1; export ORACLE_SID

if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi

alias grid_env='. /home/oracle/grid_env'
alias db_env='. /home/oracle/db_env'
Create a file called "/home/oracle/grid_env" with the following contents.
ORACLE_SID=+ASM1; export ORACLE_SID
ORACLE_HOME=$GRID_HOME; export ORACLE_HOME
PATH=$ORACLE_HOME/bin:$BASE_PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
Create a file called "/home/oracle/db_env" with the following contents.
ORACLE_SID=RAC1; export ORACLE_SID
ORACLE_HOME=$DB_HOME; export ORACLE_HOME
PATH=$ORACLE_HOME/bin:$BASE_PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
Once the "/home/oracle/grid_env" has been run, you will be able to switch between environments as follows.
$ grid_env
$ echo $ORACLE_HOME
/u01/app/11.2.0/grid
Switch environment
$ db_env
$ echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0/db_1
$
Create a Folder for Shared ASM Disks
Clone and create Second node RAC2. Copy / Paste RAC1 to same location and rename folder to RAC2 then edit following line in RAC1.vmx file
Add Virtual Machine to inventory and Start it
