This articles describes the step-by-step installation procedure of Oracle 11g Release 2 (11.2.0.1) on RHEL 5.4 (x64) operating system. |
›› Operating System: RHEL 5.4 (x64)
›› Physical memory used: 4G
›› Swap memory used: 8G
›› Oracle Release 11g (11.2.0.1)
›› Hostname: rhel5401.shannura.com (192.168.1.4)
›› Database Name [DB_NAME]: 'dbuat01'
›› Database domain [DB_DOMAIN]: 'shannura.com'
|
Additional Notes:
To determine the physical RAM, issue the following command:
$ grep MemTotal /proc/meminfo
To determine the size of the configured SWAP space, issue the following command:
$ grep SwapTotal /proc/meminfo
Swap memory used: 8G. However equal size can be assigned. For example,
Between 1024M and 2048M: 1.5 times the size of RAM
Between 2048M and 8192M: Equal to the size of RAM
More than 8192M: 0.75 times the size of RAM

i) Modify '/etc/hosts' and must contain a fully-qualified name of the host server.
<ip-address> <fully-qualified-machine-name> <machine-name>
ii) Setting kernel parameters
Add the following entries in '/etc/sysctl.conf' file.
kernel.shmmax = 68719476736 /* it's usually, 1/2 of physical RAM */
kernel.shmall = 4294967296 /* it's usually, <physical RAM> / <pagesize> */
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
|
Make the changes as permanent using:
$ /sbin/sysctl -p
|
Add the following lines to '/etc/security/limits.conf' file.
* soft nproc 2047
* hard nproc 16384
* soft nofile 4096
* hard nofile 65536
Add the following line to '/etc/pam.d/login' file.
session required pam_limits.so
Disable secure Linux by editing the '/etc/selinux/config' file.
SELINUX=disabled
|
4. Dependency Package installation |
Mount the RHEL 5.4 DVD or .iso image
$ mount /dev/cdrom /mnt
$ vi /etc/yum.repos.d/rhel-debuginfo.repo
|
/etc/yum.repos.d/rhel-debuginfo.repo
[rhel-debuginfo]
name=Red Hat Enterprise Linux $releasever - $basearch - Debug
#baseurl=ftp://ftp.redhat.com/pub/redhat/linux/enterprise/$releasever/en/os/$bas
earch/Debuginfo/
baseurl=file:///mnt/Server
enabled=1
gpgcheck=0
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
|
This ensures that the mounted DVD will be used as package repositories. Then, go ahead and install the following minimum recommended packages.

ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -u 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
