You will need to rebuild repodata to get this to work:

Disable RHN:

#vi /etc/yum/pluginconf.d/rhnplugin.conf

Hosts

cp /etc/hosts /etc/hosts.original
echo -e "127.0.0.1\t\tlocalhost.localdomain localhost" > /etc/hosts
echo -e "`ifconfig | grep "inet addr" | head -n 1 | cut -f 2 -d ":" | cut -f 1 -d " "`\t\t`hostname` `hostname | cut -f 1 -d '.'`" >> /etc/hosts

The /etc/hosts file must contain a fully qualified name for the server:

127.0.0.1		localhost.localdomain localhost
::1			localhost6.localdomain6 localhost6
10.10.10.10		ws-194-130.oeey.com ws-194-130

WARNING: If during the precheck you get a "not executed" instead of a "success" or "warning" your hosts file is wrong!

Kernel Parameters

Add the following lines to the /etc/sysctl.conf file -

cat >> /etc/sysctl.conf <<EOF

# Oracle Settings
#
# Only change default kernel.shmall and kernel.shmmax if pre-existing values
#   are lower then listed below:
# kernel.shmall = 2097152
# kernel.shmmax = 536870912
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
# memory settings
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144

EOF

Run the following command to change the current kernel parameters:

/sbin/sysctl -p

limits

Add the following lines to the /etc/security/limits.conf file:

cat >> /etc/security/limits.conf <<EOF


# Oracle Settings
*               soft    nproc   	2047
*               hard    nproc   	16384
*               soft    nofile  	1024
*               hard    nofile  	65536

EOF

Add the following line to the /etc/pam.d/login file, if it does not already exist:

cat >> /etc/pam.d/login <<EOF

# Oracle Settings
session    required     pam_limits.so

EOF

Users and Groups

Create the new groups and users and set password:

groupadd oinstall
groupadd dba
groupadd oper
useradd -g oinstall -G dba oracle
# give password to oracle user 'test12'
# passwd oracle
echo "test12" | passwd --stdin oracle

Create the directories in which the Oracle software and database files will be stored:

mkdir -p /opt/oracle
chown -R oracle.oinstall /opt/oracle
mkdir /opt/oraInventory
chown -R oracle.oinstall /opt/oraInventory

Add the following lines at the end of the Oracle user's .bash_profile file:

cat >> /home/oracle/.bash_profile <<"EOF"

# Oracle Settings
export TMP=/tmp
export TMPDIR=$TMP

export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORACLE_SID=orcl
export ORACLE_TERM=xterm
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jdk/jre:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

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

EOF

Hack OS Version

This is an important step. If you miss this Oracle will complain about OS Version comparability. This can be undone, once Oracle has been installed.

cp /etc/redhat-release /etc/redhat-release.bak
echo "redhat-4" > /etc/redhat-release

VNC

Add to the /etc/sysconfig/vncservers file

cat >> /etc/sysconfig/vncservers <<EOF

VNCSERVERS="2:oracle"
VNCSERVERARGS[2]="-geometry 800x600"

EOF

Log into the oracle user and create VNC Password

su - oracle
# give vnc login a password 'test12'
vncpasswd ; exit

Enable VNC persistent desktops at boot and start service

chkconfig vncserver on
service vncserver start

Remove # from /home/oracle/.vnc/xstartup to enable full desktop

sed -i 's%# unset SESSION_MANAGER%unset SESSION_MANAGER%g' /home/oracle/.vnc/xstartup
sed -i 's%# exec /etc/X11/xinit/xinitrc%exec /etc/X11/xinit/xinitrc%g' /home/oracle/.vnc/xstartup
# restart vncserver to take effect:
service vncserver restart

This will result in: /home/oracle/.vnc/xstartup:

#  Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc

VNC to system:

vncviewer [SYSTEM]:2

Install Oracle

# copy oracle install local

# 32bit:
unzip 10201_database_linux32.zip

# 64bit:
cat 10201_database_linux_x86_64.cpio | cpio -idmv

cd database

Oracle Installation Details:

Oracle Home Location: /opt/oracle/product/10.2.0/db_1
Installation Type: Enterprise Edition (1.3GB)
UNIX DBA Group: oinstall
Create Starter Database (additional 720MB)
  Global Database Name: orcl
  * Database Password: test12

Inventory directory: /opt/oracle/oraInventory
Operating System group name: oinstall

During the prerequisite check you should only have the following issues:

• swap - warning (due to small swap - ignore)
• network - warning (due to dhcp address - fix by static ip)

If the network has "not run" check your hosts file. If anything else is error or warned, you have problems.

Database Control URL is: http://[HOST]:1158/em

root

Near the end of the install it will ask you to run the following root:

/opt/oracle/oraInventory/orainstRoot.sh
/opt/oracle/product/10.2.0/db_1/root.sh

Unhack OS Version

mv /etc/redhat-release.bak /etc/redhat-release

Enterprise Manager

The following J2EE Applications have been deployed and are accessible at the URLs listed below.

iSQL*Plus URL:

Issues

OS Version Failed

When you run ./runInstaller you may see the following:

Starting Oracle Universal Installer...

Checking installer requirements...

Checking operating system version: must be redhat-3, SuSE-9, redhat-4, UnitedLinux-1.0, asianux-1 or asianux-2
                                      Failed <<<<

Exiting Oracle Universal Installer, log for this session can be found at
  /tmp/OraInstall2009-11-04_10-35-25AM/installActions2009-11-04_10-35-25AM.log

This means you forgot to hack the version of red hat. See instructions above.

Swap Space Requirement

Checking available swap space requirements ...
Expected result: 8112MB
Actual Result: 1983MB
Check complete. The overall result of this check is: Failed <<<<
Problem: The system does not have the required swap space.
Recommendation: Make more swap space available to perform the install.

Static IP Requirement

Checking Network Configuration requirements ...
Check complete. The overall result of this check is: Failed <<<<
Problem: The install has detected that the primary IP address of the system is DHCP-assigned.
Recommendation: Oracle supports installations on systems with DHCP-assigned public IP addresses.  
  However, the primary network interface on the system should be configured with a static IP address in
  order for the Oracle Software to function properly.  See the Installation Guide for more details on
  installing the software on systems configured with DHCP.
