Oracle Database 11gR2 Grid Infrastructure and Automatic

Storage Management for a Standalone Server (Part-1)I have successfully Installed Oracle 11gR2 Grid Infrastructure and

Automatic Storage Management for a Standalone Server on Oracle Enterprise Linux5.4. I mostly use SUSE Enterprise Linux because of YAST tool but Oracle ACFS/ADVMis not supported on SUSE Linux. Oracle Automatic Storage Management Cluster FileSystem and Oracle Automatic Storage Management DynamicVolume Manager(ACFS/ADVM) are supported only on Oracle Enterprise Linux 5 and Red Hat EnterpriseLinux 5 for Linux x86 and Linux x86-64. Maybe ACFS/ADVM support on SUSE Linuxpatches or documents are available on Oracle Metalink. Thats way I chose OEL 5.4 forGrid Infrastructure Installation.

Requirements for Oracle Grid Infrastructure Installation

1) Memory Requirement

At least 1 GB of RAM

2) Disk Space Requirement

At least 3 GB of disk space

At least 1 GB of disk space in the /tmp directory

3) Software Requirement

Linux_11gR2_grid

4) ASMLib Software Requirement

oracleasm-support-2.1.3-1.el5.i386.rpmoracleasmlib-2.0.4-1.el5.i386.rpmoracleasm-2.6.18-164.el5-2.0.5-1.el5.i686.rpm

These rpm packages are available on OEL 5.4 DVD.

5) Extra Disk Requirements

There are unformatted disk partitions are required to mark as ASM disks and form intoan ASM diskgroup. In my case these drives are named /dev/sda, /dev/sdb and dev/sdc.

Step 1


2/16

Login from Root user

Step 2

Create the accounts and groups

#groupadd -g 501 oinstall#groupadd -g 502 dba#groupadd -g 503 oper#groupadd -g 504 asmadmin#groupadd -g 505 asmoper#groupadd -g 506 asmdba#useradd -g oinstall -G dba,asmdba,oper oracle#useradd -g oinstall -G asmadmin,asmdba,asmoper,oper,dba grid

Step 3Create directories in /opt directory

#mkdir -p /opt/grid#mkdir -p /opt/oracle

Set Ownership, Group and mod of these directories

#chown -R grid:oinstall /opt/grid#chown -R oracle:oinstall /opt/oracle

#chmod -R 775 /opt/grid#chmod -R 775 /opt/oracle

Step 4Set password for grid and oracle users

#passwd grid#passwd oracle

Step 5Setting System Parameters

i) Edit the /etc/security/limits.conf file and add following lines:

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

ii) Edit the /etc/pam.d/login file and add following line:

session required pam_limits.so

iii) Edit the /etc/sysctl.conf and add following lines:

fs.aio-max-nr = 1048576fs.file-max = 6815744kernel.shmmni = 4096kernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500net.core.rmem_default = 262144net.core.rmem_max = 4194304net.core.wmem_default = 262144net.core.wmem_max = 1048586


4/16

You need reboot system or execute "sysctl -p" command to apply above settings

Step 6

i) Setting Grid User Enviroment

Edit the /home/grid/.bash_profile file and add following linesTMP=/tmp; export TMPTMPDIR=$TMP; export TMPDIRORACLE_HOSTNAME=ws1; export ORACLE_HOSTNAMEORACLE_SID=+ASM; export ORACLE_SIDORACLE_BASE=/opt/grid; export ORACLE_BASEORACLE_HOME=$ORACLE_BASE/product/Grid11gR2; export ORACLE_HOMEPATH=$ORACLE_HOME/bin:$PATH; export PATHif [ $USER = "oracle" ] || [ $USER = "grid" ]; thenif [ $SHELL = "/bin/ksh" ]; thenulimit -p 16384ulimit -n 65536elseulimit -u 16384 -n 65536fiumask 022

fi

ii) Setting Oracle User Enviroment

Edit the /home/oracle/.bash_profile file and add following lines

TMP=/tmp; export TMPTMPDIR=$TMP; export TMPDIRORACLE_HOSTNAME=ws1; export ORACLE_HOSTNAMEORACLE_BASE=/opt/oracle; export ORACLE_BASEORACLE_HOME=$ORACLE_BASE/OraDB11gR2; export ORACLE_HOMEORACLE_SID=ORCL; export ORACLE_SIDORACLE_TERM=xterm; export ORACLE_TERMPATH=/usr/sbin:$PATH; export PATH

Step 7

Some additional packages are required for successful instalation of Oracle GridInfrastructure software. To check wheter required packages are installed onyour operating system use following command:

# rpm -q binutils elfutils elfutils-libelf gcc gcc-c++ glibc glibc-common glibc-develcompat-libstdc++-33 cpp make compat-db sysstat libaio libaio-devel unixODBCunixODBC-devel|sort

Step 8

Install required ASMLib softwares

#rpm -ivh oracleasm-support-2.1.3-1.el5.i386.rpm /oracleasmlib-2.0.4-1.el5.i386.rpm /oracleasm-2.6.18-164.el5-2.0.5-1.el5.i686.rpm

Step 9


7/16

Check the available partitions

#ls -l /dev/sd*

Step 10Both ASMLib and raw devices require the candidate disks to be partitioned before they can be accessed.The following picture shows the "/dev/sda" disk being partitioned.

The remaining disks ("/dev/sdb" and "/dev/sdc") must be partitioned in the same way.

Step 11To label the disks for use by ASM, perform the following steps:

i) configure oracleasm by using the command # oracleasm configure -iand answer the prompts as shown in the screenshot.


8/16

ii) Initialize the asmlib with the oracleasm init command. This command loads theoracleasm module and mounts the oracleasm filesystem.

iii) Use the oracleasm createdisk > command to create the ASM disk label for each disk.In my casethe disks names are DISK1, DISK2 and DISK3 as shown in the screenshot.


9/16

iv) Check that the disk are visible using the oracleasm listdisks command.

vii) Check the the disks are mounted in the oracleasm filesystem with the command ls -l /dev/oracleasm/disks


10/16

Step 12i) Extract Linux_11R2_grid software into /mnt directory# unzip /mnt/Linux_11gR2_grid

Change the ownership and group of grid software directory# chown grid /mnt/grid R# chgrp oinstall /mnt/grid R

Step 13i) Now login from grid user

ii) Start the installer with the command./runInstalleriii) On the first screen of the installer, select Install and Configure Grid Infrastructure fora Standalone Server. Click Next.

iv) On the Select Product Languages screen, select the Languages that should be supported in this

installation.


11/16

v) On the CreateASMDiskGroup screen,Set Redundancy to Normal

Select the disks: ORCL:DISK

1, ORCL:DISK

2, and ORCL:DISK

3.

Click Next

vi) Specify ASM Password


12/16

vii) Privileged Operating System Groups

viii) Specify Installation Location

ix) Perform Prerequisite Checks

x) Summary

xi) The setup page shows the install progress

xii) The Execute Configuration Scripts page asks you to execute a configuration scriptas the root user.

xiii) Successfully Install
