=======
Run :
=======
/sbin/sysctl -p
=======
3b) Add the following lines to the /etc/security/limits.conf file:
==========
* soft nproc 2047
* hard nproc 16384

==========
Disable secure linux by editing the /etc/selinux/config file, making sure the SELINUX flag is set as follows:
=========
SELINUX=disabled
=========
4. Creating Oracle User Accounts :
As a root user :
=========
groupadd dba
groupadd oinstall
useradd -c "Oracle software owner" -g oinstall -G dba oracle
passwd oracle
=========
Note : //option -G : oracle is supplemntary user in the group dba
5. Creating directories :
=========
mkdir /u01/app /u01/app/oracle /u01/oradata
chown oracle:oinstall /u01/app /u01/app/oracle /u01/oradata
chmod 775 /u01/app /u01/app/oracle /u01/oradata
=========
6. Download the oracle database source file for 64 or 32 bit linux machine. Here is the site :
-----
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
-----
a). Download the Oracle 10g release 2 (10.2.0.1.0) software from Oracle website.
Extract the files using following command: For 32bit installation archive
cd /usr/local/src/
unzip 10201_database_linux32.zip
b) For 64bit installation archive
gunzip 10201_database_linux_x86_64.cpio.gz
cpio -idmv <10201_database_linux_x86_64.cpio
For RHEL 5, Centos 5: Modify database/install/oraparam.ini file and add "redhat-5" to "Certified Versions" section.
Example:
[Certified Versions]
Linux=redhat-3,SuSE-9,redhat-4,UnitedLinux-1.0,asianux-1,asianux-2,redhat-5
8. Login as root and issue the following command:
=======
xhost +
=======
Note : Either use only + or use mc ip where x windows has. + will search all attached mc where x windows has.
9. 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/10.2.0/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
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
-------------
10. cd /home/oracle
. .bash_profile //activating current settings for oracle user
Installation :
11. Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable : like
........................
su - oracle
DISPLAY=
or : DISPLAY=localhost:0.0; export DISPLAY
You may have to execute as a oracle user :
export TMP=/oratmp
export TEMPDIR=/oratmp
..............
12. Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory:
Go to database directory :
cd /usr/local/src/database
./runInstaller
13. You may see x11 windows could not find error. In that case make it sure that one x11 machine has connected to your server.
If it goes fine, try to proceed further to install oracle via GUI.
==============================
A) Post-Instalation Tasks : Auto Startup and Shutdown of Database and Listener :-
Login as root and modify /etc/oratab file and change last character to Y for apropriate database.
ORCL:$ORACLE_BASE/product/10.2.0/db_1:Y
As root user create new file "oracle" (init script for startup and shutdown the database) in /etc/init.d/ directory with following content:
===============
#!/bin/bash
#
# oracle Init file for starting and stopping
# Oracle Database. Script is valid for 10g and 11g versions.
#
# chkconfig: 35 80 30
# description: Oracle Database startup script
# Source function library.
. /etc/rc.d/init.d/functions
ORACLE_OWNER="oracle"
ORACLE_HOME="$ORACLE_BASE/product/10.2.0/db_1"
case "$1" in
start)
echo -n $"Starting Oracle DB:"
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/dbstart $ORACLE_HOME"
echo "OK"
;;
stop)
echo -n $"Stopping Oracle DB:"
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/dbshut $ORACLE_HOME"
echo "OK"
;;
*)
echo $"Usage: $0 {start|stop}"
esac
==============
Execute (as root) following commands (First script change the permissions, second script is configuring execution for specific runlevels):
chmod 750 /etc/init.d/oracle
chkconfig --add oracle --level 0356
2. Auto Startup and Shutdown of Enterprise Manager Database Control :-
As root user create new file "oraemctl" (init script for startup and shutdown EM DB Console) in /etc/init.d/ directory with following content:
================
#!/bin/bash
#
# oraemctl Starting and stopping Oracle Enterprise Manager Database Control.
# Script is valid for 10g and 11g versions.
#
# chkconfig: 35 80 30
# description: Enterprise Manager DB Control startup script
# Source function library.
. /etc/rc.d/init.d/functions
ORACLE_OWNER="oracle"
ORACLE_HOME="$ORACLE_BASE/product/10.2.0/db_1"
case "$1" in
start)
echo -n $"Starting Oracle EM DB Console:"
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/emctl start dbconsole"
echo "OK"
;;
stop)
echo -n $"Stopping Oracle EM DB Console:"
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/emctl stop dbconsole"
echo "OK"
;;
*)
echo $"Usage: $0 {start|stop}"
esac
===============
Execute (as root) following commands (First script change the permissions, second script is configuring execution for specific runlevels):
chmod 750 /etc/init.d/oraemctl
chkconfig --add oraemctl --level 0356
3. You may consider to use rlwrap for comfortable work with sqlplus and rman utility :-
RPM package for RedHat compatible (x86) distribution you can download here.
RPM package for RedHat compatible (x86_64) distribution you can download here.
su -
# rpm -ivh rlwrap*.rpm
# exit
echo "alias sqlplus='rlwrap sqlplus'" >> /home/oracle/.bash_profile
echo "alias adrci='rlwrap rman'" >> /home/oracle/.bash_profile
. /home/oracle/.bash_profile
=================
That's it try :)
