Oracle 11g R2 Real Application Cluster Implementation on RHEL 5.0
Please download the Presentation from http://www.slideshare.net/slideshow/embed_code/14108797
I have added all concepts in this ppt.

Specification:
1) 2 Node RAC setup
2) OS: Each Node machine with Red Hat Enterprise Linux Server release 5 (x86_64 bit, Kernel: 2.6.18-8.el5)
3) Storage server: 73 GB, Ubuntu 12.04 (x86_64 bit)
4) Oracle 11gR2 Database
5) Oracle 11gR2 Grid Infrastructure.

Pre-Installation:
1) All the nodes should have same OS and Kernel version and bits (x86 or x86_64)
For Linux use $uname –a command, it should show same output on all the nodes.

2) Each of the servers should have 2 NIC cards
- Where group of 2 (one from each machine) should have same name(say eth0/eth1) and IP subnet Mask
Ex: 1) Each of the machines has eth0 as Ethernet card number and IP on subnet say 10.88.33.X (Public
Network)
2) Each of the machines has eth1 as Ethernet card number and IP on subnet say 10.88.32.X (Private
Network for interconnects)
- Both of these groups on different VLANs as above. all can co-exist on the same Physical switch; that
should not be an issue

3) Configure VIP by adding entries in /etc/hosts file (VIPs must be from same subnet as that of Public IPs)

4) Stop ntpd service: Linux syncs the system time using NTP protocol. In RAC oracle has cluster time sync service
built in. if ntpd service is up then oracle will use it else oracle will create cluster synchronization service; It’s
recommended that we should use oracle cluster sync service. So will disable the ntpd service on all the
nodes:
[root@PTS0009 ~]# service ntpd stop
ntpd is stopped
[root@PTS0009 ~]# chkconfig ntpd off
[root@PTS0009 ~]# chkconfig --list ntpd
ntpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
[root@PTS0009 ~]# chkconfig ntpd --del
[root@PTS0009 ~]# mv /etc/ntp.conf /etc/ntp.conf.org
[root@PTS0009 ~]# mv /var/run/ntpd.pid /var/run/ntpd.pid.org

5) Configure SCAN (Single Client Access
Name:http://www.oracle.com/technetwork/products/clustering/overview/scan-129069.pdf)
I have DNS setup in my network so I will use the same. If you don’t have DNS setup you can hardcode these
IP addresses under /etc/hosts file.

SCAN using DNS:
1) Add Scan entry on DNS server with 3 IP addresses for same host. Enable Round Robin on DNS
(Demo: http://www.oraclemasters.in/?p=1296#dns)
Ex: ORARAC-SCAN: 10.88.33.24


ORARAC-SCAN: 10.88.33.25
ORARAC-SCAN: 10.88.33.26
2) Once the entry is added in DNS test it from Local Client as
root@PTS0009:~# nslookup orarac-scan
Server: 10.77.224.101
Address: 10.77.224.101#53
Name: orarac-scan
Address: 10.88.33.26
Name: orarac-scan
Address: 10.88.33.24
Name: orarac-scan
Address: 10.88.33.25
If you execute this command multiple times, you will notice that the list of IP addresses is varying in Round
robin fashion. If not then ask your DNS admin to enable round robin on server.
3) These above 3 IP addresses are Virtual IPs. So your Ping should fail for each of them till the time we install
Grid clusterware.

<< Execute following setups 6-9 on all the nodes >>
6) make sure each of the nodes has following Packages Installed:
Oracle Software Prerequisites Install required packages:
binutils-2.17.50.0.6
compat-libstdc++-33-3.2.3

7) Modify the kernel parameter file
Login as root and appended the following entries in /etc/sysctl.conf file.:
kernel.shmmax = 2147483648
kernel.shmmni = 4096


kernel.shmall = 2097152
kernel.sem = 250 32000 100 128
fs.file-max = 6553600
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 4194304
net.core.wmem_default = 262144
net.core.wmem_max= 262144
net.core.rmem_max = 4194304
Issue the command to reload kernel parameter:
$ sysctl –p

8) Added the following lines to the /etc/security/limits.conf file:

oracle soft nofile 131072
oracle hard nofile 131072
oracle soft nproc 131072
oracle hard nproc 131072
oracle soft core unlimited
oracle hard core unlimited
oracle soft memlock 3500000
oracle hard memlock 3500000
# Recommended stack hard limit 32MB for oracle installations
# oracle hard stack 32768
grid soft nofile 131072
grid hard nofile 131072
grid soft nproc 131072
grid hard nproc 131072
grid soft core unlimited
grid hard core unlimited
grid soft memlock 3500000
grid hard memlock 3500000
# Recommended stack hard limit 32MB for grid installations
# grid hard stack 32768

9) Install Oracleasm, oracleasmlib and oracleasm-support for ASM instance creation
1. Download Oracle ASM from (http://www.oracle.com/technetwork/server-storage/linux/downloads/rhel5-
084877.html) and installation compatible to your kernel version.
2. For my RHE Linux Kernel version: 2.6.18-8.el5 I have used following libraries
oracleasm-2.6.18-8.el5-2.0.4-1.el5.x86_64.rpm
oracleasm-2.6.18-8.el5xen-2.0.4-1.el5.x86_64.rpm
oracleasmlib-2.0.4-1.el5.x86_64.rpm
oracleasm-support-2.1.7-1.el5.x86_64.rpm

[root@PTS0009 Redhat 5]# rpm -ivh oracleasm-2.6.18-8.el5-2.0.4-1.el5.x86_64.rpm oracleasm-2.6.18-

10) SAN Storage setup as shown in PPT
Device name not persistent after reboot of RAC nodes:

I have seen that the iscsi device names are changed after reboot of RAC nodes. For e.g, device /dev/sda1
now becomes /dev/sdb1 after reboot. This behavior has caused very serious issues for the OCR and Vote
disks as well as the disks formatted with ocfs2 devices. They don't get mounted automatically because they
are not persistent after reboot. A utility called "devlabel" that are developed by Dell Inc and it is available to
download free from Dell's Official Website. This utility creates the symlink to the device names by
considering physical devices' UUID. So, even after the reboot, the UUID for any devices stays at it is and so
the symlink that you create using devlabel always points to the UUID of the device.

1) Create Symlinks
[root@PTS0006 Libs]# rpm -ivhU devlabel-0.48.03-10.x86_64.rpm
warning: devlabel-0.48.03-10.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 025e513b

2) Update the /etc/rc.local files (All RAC nodes):
After reboot of RAC nodes, the devlabel does not get started automatically so add the reload
command in /etc/rc.local
[root@PTS0006 Libs]# devlabel reload
SYMLINK: /dev/ocr -> /dev/sda1
SYMLINK: /dev/oradata -> /dev/sdb1
[root@PTS0006 Libs]# vi /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
service iscsi restart
devlabel reload
echo "Just to check if all Ethernet are up"
ifup eth0
ifup eth1
Steps for Oracle RAC:
1) Create group: dba, oinstall, asmadmin, asmdba, asmoper on all the nodes for Oracle software and ASM
2) Create users: Oracle (For oracle software owner) and grid (for oracle cluster owner) as follows:
$ id grid
uid=501(grid) gid=501(oinstall) groups=501(oinstall),502(asmadmin),503(asmdba),504(asmoper)
$ id oracle
uid=500(oracle) gid=501(oinstall) groups=501(oinstall),500(dba),503(asmdba)
3) Configure Oracle ASM:
[root@PTS0009]# oracleasm configure
ORACLEASM_ENABLED=false
ORACLEASM_UID=
ORACLEASM_GID=
ORACLEASM_SCANBOOT=true
ORACLEASM_SCANORDER=""
ORACLEASM_SCANEXCLUDE=""
[root@PTS0009]# oracleasm configure -i
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: grid
Default group to own the driver interface []: asmadmin
Start Oracle ASM library driver on boot (y/n) [n]: y

ORACLEASM_SCANEXCLUDE=""
[root@PTS0009]#
4) Load Oracle ASM:
