Download 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) - For unsupported installation.
   MOS: Oracle Database 11g Release 2 (11.2.0.3) Software (64-bit) - For supported installation.

Unpack Files

Unzip the files.

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
192.168.0.181 ol6-112.localdomain ol6-112

Oracle Installation Prerequisites

Perform either the Automatic Setup or the Manual Setup to complete the basic prerequisites. The Additional Setup is required for all installations.

Automatic Setup

If you plan to use the "oracle-rdbms-server-11gR2-preinstall" 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-rdbms-server-11gR2-preinstall

All necessary prerequisites will be performed automatically.

It is probably worth doing a full update as well, but this is not strictly speaking necessary.

# yum update

Manual Setup

If you have not used the "oracle-rdbms-server-11gR2-preinstall" 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=262144
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.
