Open a terminal window. Two options for opening a terminal window:

1. Right click on the desktop and select Open Terminal.

2. From the menu bar select Applications -> Accessories -> Terminal.

Install additional RPMs needed for the Oracle Database installation.

Mount the OS installation media.

In the open terminal window execute these commands:

mkdir /media/cdrom
mount -t iso9660 -o ro /dev/cdrom /media/cdrom
cd /media/cdrom/Server

Install RPM libaio-devel.

Execute:

rpm -ivh libaio-devel*rpm

Install RPMs unixODBC and unixODBC-devel..

Execute:

rpm -ivh unixODBC-2*rpm unixODBC-devel-2*rpm 

As root, open a terminal window and perform these steps:

Edit /etc/hosts. The file should contain text similar to the following:

127.0.0.1      localhost.localdomain    localhost
192.168.203.11 stctestbox01.us.oracle.com stctestbox01

Now check /etc/hosts the network settings are good.

Issue these commands in a terminal window.

hostname
cat /etc/hosts | grep `eval hostname`

Note: The character before eval and after hostname above is not a single quote, it is a grave accent. On a standard US keyboard, the key for the grave accent is in the upper left-hand corner, on the same key as the tilde.

The results should be similar to the following:

stctestbox01.us.oracle.com
192.168.203.11  stctestbox01.us.oracle.com   stctestbox01

Configure the kernel.

Edit /etc/sysctl.conf.

Add the following to the file:

# Kernel paramaters required by Oracle 11gR1
fs.file-max = 6553600
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144

For the /etc/sysctl.conf changes to take effect now issue this command.

sysctl -p
