Oracle 11gR2 Grid Infrastructure Installation Steps

Step By Step Installation 11gR2 Non ASM
========================================
Connect as root user:
1.) groupadd dba
2.) useradd -d /home/oracle -g dba -G dba oracle
3.) Create directories for oracle grid installation, the directory path should not be same as $ORACLE_BASE. Assuming $ORACLE_BASE=/oracle.
mkdir /oragrid
Make sure the directory as atleast 5GB free space.
4.) Change the owner of the directory to oracle:dba
chown -R oracle:dba /oragrid
5.) RPM requirements (From Metalink note# 880989.1:
1.) binutils-2.17.50.0.6-6.el5 (x86_64) 2.) compat-libstdc++-33-3.2.3-61 (x86_64) <<< both ARCH's are required. See next line. 3.) compat-libstdc++-33-3.2.3-61 (i386) <<< both ARCH's are required. See previous line. 4.) elfutils-libelf-0.125-3.el5 (x86_64) 5.) glibc-2.5-24 (x86_64) <<< both ARCH's are required. See next line. 6.) glibc-2.5-24 (i686) <<< both ARCH's are required. See previous line. 7.) glibc-common-2.5-24 (x86_64) 8.) ksh-20060214-1.7 (x86_64) 9.) libaio-0.3.106-3.2 (x86_64) <<< both ARCH's are required. See next line. 10.) libaio-0.3.106-3.2 (i386) <<< both ARCH's are required. See previous line. 11.) libgcc-4.1.2-42.el5 (i386) <<< both ARCH's are required. See next line. 12.) libgcc-4.1.2-42.el5 (x86_64) <<< both ARCH's are required. See previous line. 13.) libstdc++-4.1.2-42.el5 (x86_64) <<< both ARCH's are required. See next line. 14.) libstdc++-4.1.2-42.el5 (i386) <<< both ARCH's are required. See previous line. 15.) make-3.81-3.el5 (x86_64) 16.) elfutils-libelf-devel-0.125-3.el5.x86_64.rpm a.) requires elfutils-libelf-devel-static-0.125-3.el5.x86_64.rpm as a prerequisite, as listed below. b.) elfutils-libelf-devel and elfutils-libelf-devel-static each depend upon the other. Therefore, they must be installed together, in one (1) "rpm -ivh" command as follows: rpm -ivh elfutils-libelf-devel-0.125-3.el5.x86_64.rpm elfutils-libelf-devel-static-0.125-3.el5.x86_64.rpm 17.) glibc-headers-2.5-24.x86_64.rpm a.) requires kernel-headers-2.6.18-92.el5.x86_64.rpm as a prerequisite, as listed below 18.) glibc-devel-2.5-24.x86_64.rpm <<< both ARCH's are required. See next item. 19.) glibc-devel-2.5-24.i386.rpm <<< both ARCH's are required. See previous item. 20.) gcc-4.1.2-42.el5.x86_64.rpm a.) requires libgomp-4.1.2-42.el5.x86_64.rpm as a prerequisite, as listed below 21.) libstdc++-devel-4.1.2-42.el5.x86_64.rpm 22.) gcc-c++-4.1.2-42.el5.x86_64.rpm 23.) libaio-devel-0.3.106-3.2.x86_64.rpm <<< both ARCH's are required. See next item 24.) libaio-devel-0.3.106-3.2.i386.rpm <<< both ARCH's are required. See previous item. 25.) sysstat-7.0.2-1.el5.x86_64.rpm 26.) unixODBC-2.2.11-7.1.x86_64.rpm <<< both ARCH's are required. See next item 27.) unixODBC-2.2.11-7.1.i386.rpm <<< both ARCH's are required. See previous item. 28.) unixODBC-devel-2.2.11-7.1.x86_64.rpm <<< both ARCH's are required. See next item 29.) unixODBC-devel-2.2.11-7.1.i386.rpm <<< both ARCH's are required. See previous item.
Command to check:
rpm -qa |grep -E "binutils|compat-libstdc++|elfutils-libelf-|glibc-|glibc-common-|ksh-|libaio-|libgcc-|libstdc++|make|gcc|sysstat|unixODBC"
6.) Values for /etc/sysctl.conf (these are suggested, these values should be calculated with respect to the memory/cpu/processes of the server.)
kernel.shmall = physical RAM size / pagesize For most systems kernel.shmmax = 1/2 of physical RAM eg. for 32g ram it should be 17179869184. kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 fs.file-max = 409200 fs.aio-max-nr = 1048576 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 = 1048576
7.) Make sure u have configured a scan IP, for more details on what is scan IP please refer to: http://www.oracle.com/technetwork/database/clustering/overview/scan-129069.pdf
Make sure your /etc/hosts file has entries or hostname, host IP address, Interconnect name, Interconnect IP address, virtual hostname, virtual host IP address for all RAC nodes and on all RAC nodes.

8a.) Since we are using Network Time Protocol (NTP) for synchronization of time across all the servers in the cluster, a mandatory requirement with 11gR2 is to enable the slewing option by adding ‘-x’ argument in the ntp configuration file as seen below: -
# vi /etc/sysconfig/ntpd
# Drop root to id 'ntp:ntp' by default. OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid" #add -x in the options string. # Set to 'yes' to sync hw clock after successful ntpdate SYNC_HWCLOCK=no # Additional options for ntpdate NTPDATE_OPTIONS=""
Restart ntpd daemon.
[root@node1 oracle]# /etc/init.d/ntpd stop
Shutting down ntpd: [ OK ]
[root@node1 oracle]# /etc/init.d/ntpd start
ntpd: Synchronizing with time server: [ OK ]
Starting ntpd: [ OK ]

8b.) Update /etc/security/limits.conf with:
oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536
9.) Add following line in the /etc/pam.d/login file:
session required pam_limits.so
10.) Add the following lines to /etc/profile:
if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -u 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi
11.) Setup user equivalence between the oracle user of the rac nodes.
12.) Run Cluverify (change directory where you have copied and unzipped the oracle 11gr2 grid software)
#./runcluvfy.sh stage -pre crsinst -n node1,node2 -verbose

--Fix any error you see.

13.) Start ./runInstaller

Step by Step 11gR1 RAC CRS Installation

Oracle Global Support strongly recommends that you use Red Hat Enterprise Linux ES/AS 4 (update 3 or higher). This is kernel 2.6.9-34 or greater.

Requried RPMS: (check details on Metalink Note:437123.1)

compat-libstdc++-33-3.2.3.x86_64.rpm
elfutils-libelf-devel-0.97-5.x86_64.rpm
glibc-devel-2.3.4-2.19.x86_64.rpm
glibc-devel-2.3.4-2.19.i386.rpm (32-Bit)
gcc-3.4.5-2.x86_64.rpm
libstdc++-devel-3.4.5-2.x86_64.rpm
gcc-c++-3.4.5-2.x86_64.rpm
libaio-0.3.105-2.x86_64.rpm
libaio-0.3.105-2.i386.rpm (32-Bit)
libaio-devel-0.3.105-2.x86_64.rpm
sysstat-5.0.5-7.rhel4.x86_64.rpm
glibc-headers-2.3.4-2.19.x86_64.rpm
glibc-kernheaders-2.4-9.1.98.EL.x86_64.rpm

To query rpm installed in your system:
rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" | grep compat-libstdc++

Sample sysctl.conf
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=262144
net.core.rmem_max=262144
net.core.wmem_default=262144
net.core.wmem_max=262144
net.ipv4.tcp_wmem = 262144 262144 262144
net.ipv4.tcp_rmem = 4194304 4194304 4194304

Add the following settings to /etc/security/limits.conf

oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

Add or edit the following line in the /etc/pam.d/login file, if it does not already exist:
session required pam_limits.so

Add the following lines to /etc/profile:

if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
This is how the /etc/hosts file look like:
[oracle@oradbdev02 ~]$ more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
#127.0.0.1 localhost.localdomain localhost
127.0.0.1 oradbdev02.xxxx.com oradbdev02
# Public
10.66.81.61 oradbdev01.xxxx.com oradbdev01
10.66.81.62 oradbdev02.xxxx.com oradbdev02
#Private
192.168.0.61 oradbdev01-priv.xxxx.com oradbdev01-priv
192.168.0.62 oradbdev02-priv.xxxx.com oradbdev02-priv
#Virtual
10.66.81.198 oradbdev01-vip.xxxx.com oradbdev01-vip
10.66.81.199 oradbdev02-vip.xxxx.com oradbdev02-vip

Imp metalink notes to look at before installation: 452780.1.

Setup user equivalence between the rac nodes.
Check that oracle is able to ssh between the rac servers without having to type the password.
Setup up location of OCR & Voting disk files. For test purposes I used the same mount point with different folders for each e.g.
/DB01/ocr
/DB01/voting_disk

Now run the cluster verify utility to do a pre-check before the cluster installation.
[oracle@oradbdev01 clusterware]$ ./runcluvfy.sh stage -pre crsinst -n oradbdev01,oradbdev02 -verbose

System requirement failed for 'crs'

Pre-check for cluster services setup was unsuccessful on all the nodes.

The check has failed for me for checking if oracle users primary group is "oinstall". I am using dba as the groups. Hence I am omitting this error.

Now we are all set to start the OUI
[oracle@oradbdev01 clusterware]$ /home/oracle/software/11g/Cluster/clusterware/runInstaller
