I will be listing down steps for 11g Release 2 installation on Linux x86. There has been few changes incorporated in 11gR2 which must be given due consideration before starting installation. ASM instance now runs from new Oracle Home called Grid Infrastructure.

If you wish to use ASM for storing database files, then you should install first Oracle grid infrastructure for a standalone server. It is also required if you wish to use Oracle Restart feature (Provides for automatic restart of DB and other components after a hardware or software failure or whenever your database host computer restarts) for single instance.

Environment used for this setup
Operating System – Oracle Enterprise Linux Release 5(OEL5) on Vmware
Physical Ram – 1Gb

Asmlib for labeling ASM Disks.Refer to following OTN article for configuring asmlib and creating disks.

Software can be downloaded from OTN at following link

Oracle Database 11g Release 2 Grid Infrastructure (11.2.0.1.0) for Linux x86

Oracle Database 11g Release 2 (11.2.0.1.0) for Linux x86

All the pre-requisites for installation can be found here
http://download.oracle.com/docs/cd/E11882_01/install.112/e10840/pre_install.htm

I have tried to shorten it by keeping things which are relevant to our setup.

If you have yum installed on your machine, then it is very easy to install the packages. You can copy the list of packages in a text file and insert ‘yum install ‘ in beginning and execute it as root. This will install any missing packages. To know more about setting up yum, refer to my previous post

If Kernel parameters are not setup correctly, Oracle 11g OUI provides you  a fixup script and also ability to resume the installation process without need to re-run the earlier steps. Please refer to article here

Users,Roles and Groups for Installation

osdba group for ASM – Membership in the OSDBA group allows access to the files managed by Automatic Storage Management. It can be same as database osdba group. We will be using group dba in our setup.
OSASM group – Members of the OSASM group can use SQL to connect to an Automatic Storage Management instance as SYSASM using operating system authentication. The SYSASM privileges permit mounting and dismounting disk groups, and other storage administration tasks. SYSASM privileges provide no access privileges on an RDBMS instance. We will use asmadmin

OSOPER group – Similar to SYSOPER privilege in RDBMS, this is used for limited privileges like starting up and stopping the Oracle ASM instance. We will not be using separate group for it, will be selecting dba in our setup

oinstall – This is similar to previous releases, and used for Oracle Inventory group

I am using oracle user for installing Grid Infrastructure and Oracle Database Software. You can have a separate user say oragrid with oinstall membership and permission on oracle inventory directory.

Create Base directory where software will be installed. I used /u02/app/oracle

Add users and groups

/usr/sbin/groupadd -g 501 dba
/usr/sbin/groupadd -g 504 asmadmin
/usr/sbin/groupadd oinstall

/usr/sbin/useradd -u 502 -g oinstall -G dba,asmadmin oracle

Add following entries 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/replace following entries in /etc/sysctl.conf

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
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

Execute following command as root to change the current kernel parameters:

/sbin/sysctl -p

Copy following in your login profile.

if [ $USER = "oracle" ]; then
        if [ $SHELL = "/bin/ksh" ]; then
              ulimit -p 16384
              ulimit -n 65536
        else
              ulimit -u 16384 -n 65536
        fi
umask 022
fi

We need to start with Grid Infrastructure installation. Unzip the contents and execute  runInstaller . This would require 2.8Gb of disk space.

$./runInstaller

Please click on image below for  displaying screenshots for 11gR2 Grid Infrastructure installation

Execute root.sh from Grid ORACLE_HOME as root user

The following environment variables are set as:
    ORACLE_OWNER= oracle
    ORACLE_HOME=  /u02/app/oracle/product/11.2.0/grid

Enter the full pathname of the local bin directory: [/usr/local/bin]:
The file "dbhome" already exists in /usr/local/bin.  Overwrite it? (y/n)
[n]: y
   Copying dbhome to /usr/local/bin ...
The file "oraenv" already exists in /usr/local/bin.  Overwrite it? (y/n)

   Copying oraenv to /usr/local/bin ...
The file "coraenv" already exists in /usr/local/bin.  Overwrite it? (y/n)
[n]: y
   Copying coraenv to /usr/local/bin ...

Entries will be added to the /etc/oratab file as needed by

To install Database software, Unzip the contents of both the zip files and execute runInstaller . Ensure you have 3.95Gb of free disk space

$./runInstaller
