Install Oracle 10g Release 2 on Redhat 5 Enterprise Edition

ORACLE 10G

INSTALLATION ON LINUX REDHAT 5

LOGIN AS ROOT USER

STEP # 1:  SET KERNEL PARAMETERS on SYSCTL.CONF file

type in Terminal 
cd /etc

ls

gedit sysctl.conf à File open on editor mode add the following parameters

kernel.shmall = 2097152

kernel.shmmax = 2147483648

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 65536

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default = 262144

net.core.rmem_max = 262144

net.core.wmem_default = 262144

net.core.wmem_max = 262144

•  fs.file-max sets the maximum number of open files that can be handled by the Linux kernel.
• kernel.shmall determines the total amount of shared memory to be allocated in pages.
• kernel.shmmax controls the maximum amount of memory to be allocated for shared memory which.
• kernel.shmmni defines the maximum number of segments system-wide.
• net.core.rmem_default and net.core.rmem_max define the default and maximum read buffer queue for network operations (1 MB in this example)
• net.core.wmem_default and net.core.wmem_max define the default and maximum write buffer queue for network operations (256 KB in this example)
• net.ipv4.ip_local_port_range tells the kernel the port ranges that will be used for outbound connections.
• kernel.sem has four parameters:
• SEMMSL – semaphores per array
• SEMMNS – max semaphores system-wide (SEMMNI*SEMMSL)
• SEMOPM – max operations per semop call
• SEMMNI – max number of semaphore arrays

Run the following command in Terminal  to change the kernel parameters

/sbin/sysctl –p

STEP # 2:  SET PARAMETERS on LIMITS.CONF file

Cd /etc/security

ls

gedit limits.conf à File open on editor mode add the following parameters

*          soft     nproc            2047

*          hard   nproc 16384

*          soft     nofile             1024

*          hard   nofile             65536

STEP # 3:    ADD PARAMETER ON LOGIN file

cd /etc/pam.d

ls

gedit login à File open on editor mode add the parameters

session         required       pam_limits.so

STEP # 4:    INSTALL REQUIRED RPM FROM LINUX CD’S 

From CD # 1

Cd /media/cdrom/Server

rpm –Uvh setarch-*

rpm –Uvh make-3*

rpm –Uvh libaio-0*

rpm –Uvh --force tcl-*

rpm –Uvh glibc-*

From CD # 2

Cd /media/cdrom/Server

rpm –Uvh libXp-1*

rpm –Uvh compat-libstdc++-33*

rpm –Uvh compat-libf2c-34-*

rpm –Uvh compat-gcc-34-*

rpm –Uvh compat-gcc-34-c++-3*

rpm –Uvh compat-libstdc++-296*

rpm –Uvh gcc-4*

From CD # 3

Cd /media/cdrom/Server

rpm –Uvh compat-db-4*

rpm –Uvh openmotif-2*

 STEP # 5:   

Create 2 groups:   

groupadd oinstall

groupadd dba

Create a user and assign the above groups to user

useradd –g oinstall –G dba oracle

passwd oracle

Create directories using mkdir command

mkdir –p /u01/app/oracle

Change the ownership of above directories and allow permissions

chown  –R oracle:oinstall  /u01/app

chmod  –R 775  /u01/app

  STEP # 6:  CHANGES ON REDHAT-RELEASE File

Cd /etc

mv redhat-release redhat-release.old

gedit redhat-release

Redhat-4

  STEP # 7:              Login As Oracle User

Gedit .bash_profile

# Oracle Settings

TMPDIR=$TMP; export TMPDIR

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

Logout from Oracle user 

  STEP # 8:              Login As Root User  

create folder @ /u01/app named “10g”

copy all files from cdrom to /u01/app/10g

chmod –R 775 /u01/app/10g

now login as oracle user and run following command 

from /u01/app/10g 

e.g

cd /u01/app/10g

./runInstaller

  STEP # 9:              Run Scripts As Root User (as appear on screen)
