Oracle Database 10g ( Installation On Red Hat Enterprise Linux 3 (RHEL3)

In this article I'll describe the installation of Oracle Database 10g Release 2 ( on Red Hat Enterprise Linux 3 (RHEL3). The article is based on a server installation with a minimum of 2G swap, secure Linux disabled and the following package groups installed.

The installation is certified against RHEL3 Update 3 or above, but it will work against the initial release with some minor adjustments. Alternative installations may require more packages to be loaded, in addition to the ones listed below.

Download Software

Download the following software.

Unpack Files

Unzip the files.

unzip 10201_database_linux32.zip

You should now have a single directory containing installation files. Depending on the age of the download this may either be named "db/Disk1" or "database".

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     pam_limits.so

Note by Kent Anderson: In the event that pam_limits.so cannot set privileged limit settings see Bug 115442.


Install the following packages.

# From RedHat AS3 Disk 2
cd /mnt/cdrom/RedHat/RPMS
rpm -Uvh setarch-1*
rpm -Uvh openmotif-2*

# From RedHat AS3 Disk 3
cd /mnt/cdrom/RedHat/RPMS
rpm -Uvh compat-libstdc++-7*
rpm -Uvh compat-libstdc++-devel-7*
rpm -Uvh compat-db-4*
rpm -Uvh compat-gcc-7*
rpm -Uvh compat-gcc-c++-7*
rpm -Uvh libaio-0*

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/10.2.0/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

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME
PATH=/usr/sbin:$PATH; export PATH


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


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 database directory.


During the installation enter the appropriate ORACLE_HOME and name then continue with the installation.

When using the first release of RHEL AS 3.0 the pre-requesite check will complain about the version of the glibc package. To continue simply tick this error to confirm you wish to proceed anyway. The installation will work correctly but you will not have a supported installation. This issue doesn't occur with RHEL AS 3.0 Update 3 or above.
