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
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

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

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)
