Oracle 10G Installation on Red Hat Linux

First Install Linux with all the rpms and packages required.

1. Create Groups oinstall & dba, and oracle user as follows:

#groupadd oinstall
#groupadd dba
#useradd -g oinstall -G dba oracle
#passwd oracle

give a new password

2. Edit the .bash_profile file of oracle user and add the following lines as follows:

#vi /home/oracle/.bash_profile

umask 022

PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
LD_LIBRARY_PATH=/usr/lib:/usr/X11R6/lib

ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=$ORACLE_BASE/product/10.1.0/db_1
ORACLE_SID='SERVICE_NAME'
PATH=$ORACLE_HOME/bin:$PATH

export PATH LD_LIBRARY_PATH
export ORACLE_BASE ORACLE_HOME ORACLE_SID

:wq(save and exit)

3. Then run the .bash_profile to make the current changes effect

#. .bash_profile

Create the directory for the software installation and assign ownership to oracle:oinstall. In the example, you use /u01/app/oracle.

#mkdir -p /u01/app/oracle
#mkdir -p /u01/app/oracle/product/10.1.0/db_1

Then change the permissions accordingly

#chown -R oracle:oinstall /u01/app
#chmod -R 775 /u01/app

4. Edit the /etc/inittab file and change the runlevel from 5 to 3.
Note: Not required if using Oracle's Enterprise Linux.

5. If your OS is greater than RHEL 3, then the Oracle Universal Installer does not recognize the OS, change the version to 3 as follows:

#cp /etc/redhat-release /etc/redhat-release.orig
#vi /etc/redhat-release

#And replace the line present in the file with
Red Hat Enterprise Linux AS release 3 (Taroon)
:wq

Once the installation is completed replace the orignal file back.

#cp /etc/redhat-release.orig /etc/redhat-release

overwrite:yes

6. Change the Kernel Parameters according to your Hardware:

#vi /etc/sysctl.conf

kernel.sem= 250 32000 100 128
kernel.shmmax = 2147483648
kernal.shmmni = 4096
kernel.shmall = 262144000
fs.file-max= 1024
net.ipv4.ip_local_port_range= 1024 65000

:wq

Note: If any of the value is more than the value given above don't change those values.

7. To make the changes effect immediately without reboot give the following command:

#/sbin/sysctl -p

8. REBOOT(init 6) the system and login as oracle User:

9. You need to install Oracle in the GUI mode so change the display mode to GUI by giving followinh command:

$startx

10. Mount the media disk which contains the Oracle 10G software:
Note: It is recommended that you copy the contents of the CD onto the Filesystem and start the installation:

$cp /mnt/disk1/*.* /home/oracle/oracle10g

Give total permissions on the newly created folder oracle10g to oracle user

$chmod -R 777 /home/oracle/oracle10g

11. Then Start the installation as follows:

$sh /home/oracle/oracle10g/runinstaller.sh

The OUI is started and continue Installation of Oracle same as in Windows:

next>next>next>.....................................Finish.

Inbetween it prompts you to run two scripts as root

DON'T close the current window until you run the respected script as root in a new terminal.

1st script:

#root>sh /u01/app/oracle/oraInventory/orainstall.sh

After executing this script as root go to the previous screen and press the continue tab

2nd script:

#root> sh /u01/app/oracle/product/10.1.0/db_1/root.sh

After executing this script as root go to the previous screen and press the OK tab.


Your Installation of Oracle 10G on Linux is completed successfully(hopefully).
