LinuxQuestions.org - Installation problem of oracle 10g on rhel5

Hi,

I'm new to linux i'm using rhel5. I'm using mysql database on my machine. On the same OS i tried to install oracle10g. I googled and i followed the following steps. Here i'm mentioning the steps i followed clearly.

REQUIREMENTS
Hardware Requirements
• 1 GB RAM (RECOMENDED)
• 1.5 GB of swap space
• 500 MB of disk space in the /tmp directory
• 2-4 GB disk space for the Oracle software
• 1.2 GB for the precongured database (optional)
• 2.4 GB for the ash recovery area (optional)
Software Requirements

Make sure that you have the following librarypackages :

libXp, compat-libstdc++

It is required to have the following packages which you can check with the following command:
rpm -q binutils compat-db control-center gcc gcc-c++ glibc glibc-common gnome-libs libstdc++ libstdc++-devel make pdksh sysstat xscreensaver

Changing the Red Hat Release

As RHEL5 has been released after Oracle 10g was, Oracle 10g does not support
RHEL5 ocially. The latest version 10g supports in RHEL4. So we have to get
round it by changing the release conguration:
echo “rhel4″ > /etc/redhat-release
Creating the oracle user account
We need to create oinstall and dba groups and an oracle account belonging to
them. When logged as root user,
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -m -g oinstall -G dba oracle
Set the password for the oracle user:
passwd oracle
You can set “oracle” as the password too
Creating the Installation Path and Setting the Permissions
mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/oracle
Conguring Kernel Parameters

Add the following set of kernel parameters in /etc/sysctl.conf :

kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 658576
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 1048536
net.core.wmem_max = 1048536

Activate the modification in kernel parameters with the following command:

/sbin/sysctl -p

CONFIGURING SHELL LIMITS

Add the following lines in /etc/security/limits.conf :

oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
Add the line below in /etc/pam.d/login :

session required /lib/security/pam_limits.so

Add the following profile setting s in /etc/profile :

if [ \$USER = "oracle" ]; then
if [ \$SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi

Add the following login setting in /etc/csh.login :

if ( \$USER == “oracle” ) then
limit maxproc 16384
limit descriptors 65536
umask 022
endif

CONFIGURE HANGCHECK TIMER

Add the following line in /etc/rc.d/rc.local :
modprobe hangcheck-timer hangcheck_tick=30 hangcheck_margin=180

ENVIRONMENT SETTINGS FOR ORACLE USER
Login as oracle user :
su - oracle
To set the environment variables, append the following lines in /home/oracle/.bash_prole:

# User specific environment and startup programs
umask 022
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
export LD_LIBRARY_PATH=/usr/lib:/usr/X11R6/lib
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=\$ORACLE_BASE/product/10.2.0/db_1
export ORACLE_SID=orcl
PATH=\$ORACLE_HOME/bin:\$ORACLE_HOME/jdk/jre/lib/i386/server:\
\$ORACLE_HOME/rdbms/lib:\$ORACLE_HOME/lib:\$LD_LIBRARY_PATH:\
/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/sbin:\
/usr/sbin:/root/bin:\$PATH
PATH=\$PATH:\$HOME/bin
export PATH
unset USERNAME

Activate these variables and the paths with:

source ~/.bash_profile

INSTALLATION

Running the Installer in a root terminal :

##########################
#xhost +
access control disabled, clients can connect from any host
###########################

su – oracle
Extract the 10201_database_linux32.zip le into /u01, or somewhere else where oracle user can access :

unzip 10201_database_linux32.zip -d /u01
cd /u01/database ./runInstaller

The installation dialog will now start.

If you face errors about some libs are not found, consider installing the following packages: libXp compat-libstdc++ from http://www.rpmnd.net OR http://rpm.pbone.net
