Oracle Application Server 10g Release 2 (10.1.2) Installation On RedHat Advanced Server 3.0 (Update 3)

In this article I'll describe the installation of Oracle Application Server 10g Release 2 (10.1.2), Oracle's J2EE Application Server, on RedHat Advanced Server 3.0 (update 3). The article assumes you've performed the standard advanced server installation including the development tools.
Note. I've experienced issues with installations on systems that are updated beyond Update 3, which is the version certified by Oracle.

Download Software

Download the following software:

Unpack Files

Unpack the contents of the file:
cpio -idmv < as_linux_x86_core_101200.cpio
You should now have a 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 = 256 32000 100 142
fs.file-max = 131072
net.ipv4.ip_local_port_range = 10000 65000
kernel.msgmni = 2878 
kernel.msgmax = 8192 
kernel.msgmnb = 65535
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        2048
*        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 AS3 Disk 2
cd /mnt/cdrom/RedHat/RPMS
rpm -Uvh setarch-1.3-1.i386.rpm
rpm -Uvh sysstat-4.0.7-4.EL3.3.i386.rpm

# From RedHat AS3 Disk 3
cd /mnt/cdrom/RedHat/RPMS
rpm -Uvh openmotif21-2.1.30-8.i386.rpm
rpm -Uvh ORBit-0.5.17-10.4.i386.rpm
rpm -Uvh libpng10-1.0.13-15.i386.rpm
rpm -Uvh gnome-libs-1.4.1.2.90-34.1.i386.rpm
rpm -Uvh compat-glibc-7.x-2.2.4.32.6.i386.rpm \
         compat-gcc-7.3-2.96.128.i386.rpm \
         compat-gcc-c++-7.3-2.96.128.i386.rpm \
         compat-libstdc++-7.3-2.96.128.i386.rpm \
         compat-libstdc++-devel-7.3-2.96.128.i386.rpm
Create the new groups and users:
groupadd oinstall
groupadd dba
groupadd oper

useradd -g oinstall -G dba -s /bin/ksh oracle
passwd oracle
Create the directories in which the Oracle software will be installed:
mkdir -p /u01/app/oracle/product/j2ee_10_1_2
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 .profile file:
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/j2ee_10_1_2; export ORACLE_HOME
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$ORACLE_HOME/bin:$PATH; export PATH
PATH=$PATH:$ORACLE_HOME/dcm/bin:$ORACLE_HOME/opmn/bin; export PATH
PATH=$PATH:$ORACLE_HOME/Apache/Apache/bin; export PATH

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

PS1="`hostname`> "
set -o emacs
set filec

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

With the installation complete you can perform any administration tasks using Enterprise Manager:
