Oracle 11g R2 Installation on Oracle Enterprise Linux 5.4

1    Hardware Requirements

----CHECK PHYSICAL RAM

We need at least 1GB of physical RAM.

# grep MemTotal /proc/meminfo

----CHECK SWAP SPACE

RAM between 1GB and 2GB then swap=1.5 times of RAM.

RAM between 2GB and 16GB then swap=equal to the size of RAM.

RAM is more than 16GB then swap size=16GB.

Note:If we have 2GB RAM,the swap size is 3GB.

#grep SwapTotal /proc/meminfo

----CHECK SPACE AVAILABLE IN /tmp

We need at least 1GB of space in /tmp directory.

#df –h /tmp

----CHECK RESOLUTION

To install Oracle 11g R2 in your system should be running on at least 1024*768 screen resolution.

#xdpyinfo | grep ‘dimensions:’

----CHECK KERNEL VRSION

We need the kernel version 2.6.18 or above

#uname -r

-- Activate changes
/sbin/sysctl -p

5.As root: Set Shell Limits

 -- Modify limits.conf

Vi /etc/security/limits.conf Place these lines in the end of the file. oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 EOF

9.As root: Modify .bashrc

# cd /home/oracle
vi .bashrc
-- append the following:

umask 022 ORACLE_HOSTNAME=?.mlib.org ORACLE_BASE=/app/oracle/product ORACLE_HOME=/app/oracle/product/11.2.0/db_1 ORACLE_SID=?

-- close all open terminal windows and open new ones
# set
-- validate the environment

10.Run the file for to start Installation

Unzip the oracle file in “tmp” folder.

After unzipping the installation files, change the user as “oracle” and take “database” folder.

Su oracle

cd /tmp/database/

./runInstaller

Note:If any one of the checking is failed during installation starting,take new terminal and use

Su root

Xhost +SI:localuser:oracle
