Oracle Database 10g (10.1.0.2) Installation On RedHat Advanced Server 2.1

In this article I'll describe the installation of Oracle Database 10g (10.1.0.2) on RedHat Advanced Server 2.1. The article is based on a server installation with a minimum of 2G swap, secure Linux disabled and the following package groups installed:
Alternative installations may require more packages to be loaded, in addition to the ones listed below.

Download Software

Download the following software:

Unpack Files

First unzip the files:
gunzip ship.db.cpio.gz
Next unpack the contents of the files:
cpio -idmv < ship.db.cpio
You should now have a single directory (Disk1) containing installation files.

Hosts File

The /etc/hosts file must contain a fully qualified name for the server:
<IP-address>  <fully-qualified-machine-name>  <machine-name>

Set Kernel Parameters

Add the following lines to the /etc/sysctl.conf file:
kernel.shmall = 2097152
kernel.shmmax = 2147483648
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
Run the following command to change the current kernel parameters:
/sbin/sysctl -p
Add the following lines to the /etc/security/limits.conf file:
*               soft    nproc   2047
*               hard    nproc   16384
*               soft    nofile  1024
*               hard    nofile  65536
Add the following line to the /etc/pam.d/login file, if it does not already exist:
session    required     /lib/security/pam_limits.so

Setup

Install the following packages:
# From RedHat AS21 Disk 1
cd /mnt/cdrom/RedHat/RPMS
rpm -Uvh openmotif-2*
cd /
eject
Create the new groups and users:
groupadd oinstall
groupadd dba
groupadd oper

useradd -g oinstall -G dba oracle
passwd oracle
Create the directories in which the Oracle software will be installed:
mkdir -p /u01/app/oracle/product/10.1.0/db_1
chown -R oracle.oinstall /u01
Login as root and issue the following command:
xhost +<machine-name>
Login as the oracle user and add the following lines at the end of the .bash_profile file:
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.1.0/db_1; export ORACLE_HOME
ORACLE_SID=TSH1; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
LD_ASSUME_KERNEL=2.4.1; export LD_ASSUME_KERNEL

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

Installation

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable:
DISPLAY=<machine-name>:0.0; export DISPLAY
Start the Oracle Universal Installer (OUI) by issuing the following command in the Disk1 directory:
./runInstaller
During the installation enter the appropriate ORACLE_HOME and name then continue with the installation.

Post Installation

Finally edit the /etc/oratab file setting the restart flag for each instance to 'Y':
TSH1:/u01/app/oracle/product/10.1.0/db_1:Y
