Oracle Database 10g (10.1.0.2) Installation On Fedora Core 2 (FC2)

In this article I'll describe the installation of Oracle Database 10g (10.1.0.2) on Fedora Core 2. The article is based on a Fedora Core 2 Server Installation with a minimum of 2G swap and the following package groups installed:

* X Window System
* GNOME Desktop Environment
* KDE Desktop Environment
* Editors
* Graphical Internet
* Text-based Internet
* Server Configuration Tools
* Windows File Server
* Network Servers
* Development Tools
* Kernel Development
* Administration Tools
* System Tools


Alternative installations may require additional packages to be loaded in addition to the ones listed below.

* Download Software
* Unpack Files
* Hosts File
* Set Kernel Parameters
* Setup
* Installation
* Post Installation

Download Software
Download the following software:

* Oracle Database 10g (10.1.0.2) 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
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

Note by Kent Anderson: In the event that pam_limits.so cannot set privilidged limit settings see Bug 115442.
Setup
Install the following packages:

# From Fedora Core 2 Disk 1
cd /mnt/cdrom/Fedora/RPMS
rpm -Uvh setarch-1.4-1.i386.rpm
rpm -Uvh tcl-8.4.5-7.i386.rpm

# From Fedora Core 2 Disk 2
cd /mnt/cdrom/Fedora/RPMS
rpm -Uvh openmotif-2.2.3-2.i386.rpm

# From Fedora Core 2 Disk 3
cd /mnt/cdrom/Fedora/RPMS
rpm -Uvh compat-libstdc++-7.3-2.96.126.i386.rpm
rpm -Uvh compat-libstdc++-devel-7.3-2.96.126.i386.rpm
rpm -Uvh compat-db-4.1.25-2.1.i386.rpm
rpm -Uvh compat-gcc-7.3-2.96.126.i386.rpm
rpm -Uvh compat-gcc-c++-7.3-2.96.126.i386.rpm

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>

Edit the /etc/redhat-release file replacing the current release information (Fedora Core release 2 (Tettnang)) with the following:

redhat-3

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 a "software only" installation.
Post Installation
As the oracle user issue the following commands:

cd $ORACLE_HOME/bin

mv oracle oracle.bin

cat >oracle <<"EOF"
#!/bin/bash

export DISABLE_HUGETLBFS=1
exec $ORACLE_HOME/bin/oracle.bin $@
EOF

chmod +x oracle

This should prevent the "ORA-27125: unable to create shared memory segment" being produced by the DBCA.

Edit the /etc/redhat-release file restoring the original release information:

Fedora Core release 2 (Tettnang)

Finally edit the /etc/oratab file setting the restart flag for each instance to 'Y':

TSH1:/u01/app/oracle/product/10.1.0:Y
