Download Software

Download Sun's Java Development Kit (JDK 1.3.1).

Download the Oracle installation files from otn.oracle.com.

Unpack Files

First unzip the files:

gunzip lnx_920_disk1.cpio.gz
gunzip lnx_920_disk2.cpio.gz
gunzip lnx_920_disk3.cpio.gz

Next unpack the contents of the files:

cpio -idmv < lnx_920_disk1.cpio
cpio -idmv < lnx_920_disk2.cpio
cpio -idmv < lnx_920_disk3.cpio

You should now have three directories (Disk1, Disk2 and Disk3) containing installation files.

Set Kernel Parameters

The following table contains minimum kernel settings. If the current settings exceed these figures then do not alter them:

Parameter	Minimum Setting
SEMMNI	100
SEMMNS	256
SEMOPM	100
SEMMSL	100
SHMMAX	2147483648
SHMMIN	1
SHMMNI	100
SHMSEG	4096
SHMVMX	32767

The current semaphore settings can be viewed using the following command:

cat /proc/sys/kernel/sem

250 32000 32 128

The values listed are for the SEMMSL, SEMMNS, SEMOPM, and SEMMNI parameters. The adjusted values can be set using:

# echo SEMMSL_value SEMMNS_value SEMOPM_value SEMMNI_value > /proc/sys/kernel/sem
echo 250 32000 100 128 > /proc/sys/kernel/sem

The shared memory settings can be viewed using the following command:

cat shared_memory_parameter

The values can be set using:

echo 2147483648 >  /proc/sys/kernel/shmmax

Set the File Handles, Sockets and Process limit using:

echo 65536 > /proc/sys/fs/file-max
ulimit -n 65536
echo 1024 65000 > /proc/sys/net/ipv4/ip_local_port_range
ulimit -u 16384

The necessary parameter changes can be combined in a script and run during system startup:

echo 250 32000 100 128 > /proc/sys/kernel/sem
echo 65536 > /proc/sys/fs/file-max
ulimit -n 65536
echo 1024 65000 > /proc/sys/net/ipv4/ip_local_port_range
ulimit -u 16384

Setup

Install the Java development kit:

tar -xvjf j2sdk-1.3.1-FCS-linux-i386.tar.bz2 -C /usr/local/

Create the new groups and users:

groupadd oinstall
groupadd dba
groupadd oper
groupadd apache

useradd -g oinstall -G dba oracle
passwd oracle

useradd -g oinstall -G apache apache
passwd apache

Create the directories in which the Oracle software will be installed:

mkdir /home/oracle/product
mkdir /home/oracle/product/9.2.0.1.0
chown -R oracle.oinstall /home/oracle
mkdir /usr/temp
chmod 777 /usr/temp

xhost +<machine-name>

# Oracle 9i
ORACLE_BASE=/home/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/9.2.0.1.0; export ORACLE_HOME
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=$ORACLE_HOME/bin:$PATH:/usr/local/java131/bin; export PATH
ORACLE_SID=TSH1; export ORACLE_SID

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

TMP=/usr/temp; export TMP
TMPDIR=$TMP; export TMPDIR

Save the .bash_profile file and re-login as the oracle user. Make sure the .bash_profile ran correctly by issuing the following command:

set | more

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

Continue with the installation as normal.

Before the linking phase of the installation begins you should edit the $ORACLE_HOME/bin/genclntsh script altering the following line:

LD_SELF_CONTAINED="-z defs"

to:

LD_SELF_CONTAINED=""

The linking phase should now proceed correctly.

Post Installation

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

TSH1:/home/oracle/product/9.2.0.1.0:Y
