Download the following software.

Download the Oracle software from OTN or MOS depending on your support status.

OTN: Oracle Database 11g Release 2 (11.2.0.1) Software (64-bit)

MOS: Oracle Database 11g Release 2 (11.2.0.2 or 11.2.0.3) Software (64-bit)

Unpack Files

Unzip the files.

# 11.2.0.1
unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip

#11.2.0.2
unzip p10098816_112020_Linux-x86-64_1of7.zip
unzip p10098816_112020_Linux-x86-64_2of7.zip

#11.2.0.3
unzip p10404530_112030_Linux-x86-64_1of7.zip
unzip p10404530_112030_Linux-x86-64_2of7.zip

You should now have a single directory called "database" containing installation files.

Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server.

<IP-address>  <fully-qualified-machine-name>  <machine-name>

For example.

127.0.0.1       localhost.localdomain  localhost
192.168.2.181   ol5-11gr2.localdomain  ol5-11gr2

Oracle-Validated Setup

If you plan to use the "oracle-validated" package to perform all your prerequisite setup, follow the instructions at
http://public-yum.oracle.com to setup the yum repository for OL, then perform the following command.

# yum install oracle-validated

All necessary prerequisites will be performed automatically.

Manual Setup

If you have not used the "oracle-validated" package to perform all prerequisites, you will need to manually perform the following setup tasks.

Oracle recommend the following minimum parameter settings.

fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
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 = 1048586

The current values can be tested using the following command.

/sbin/sysctl -a | grep <param-name>

Add or amend the following lines in the "/etc/sysctl.conf" file.

fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default=4194304
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048586

Run the following command to change the current kernel parameters.

/sbin/sysctl -p

Add the following lines to the "/etc/security/limits.conf" file.

oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  4096
oracle              hard    nofile  65536
oracle              soft    stack   10240
