Download the Oracle software from OTN or MOS depending on your support status.
- OTN: Oracle Database 11g Release 2 (18.104.22.168) Software (64-bit) - For unsupported installation.
- MOS: Oracle Database 11g Release 2 (22.214.171.124) Software (64-bit) - For supported installation.
Unzip the files.

You should now have a single directory called "database" containing installation files.
The "/etc/hosts" file must contain a fully qualified name for the server.
<IP-address> <fully-qualified-machine-name> <machine-name>
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.
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
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.
Add the following lines to the "/etc/security/limits.conf" file.
oracle soft nproc 16384 oracle hard nproc 16384 oracle soft nofile 4096 oracle hard nofile 65536 oracle soft stack 10240
Install the following packages if they are not already present.

This will install all the necessary 32-bit packages for 18.104.22.168. From 22.214.171.124 onwards many of these are unnecessary, but having them present does not cause a problem.
Create the new groups and users.
groupadd -g 501 oinstall groupadd -g 502 dba groupadd -g 503 oper groupadd -g 504 asmadmin groupadd -g 506 asmdba groupadd -g 505 asmoper useradd -u 502 -g oinstall -G dba,asmdba,oper oracle passwd oracle
We are not going to use the "asm" groups, since this installation will not use ASM.
Set the password for the "oracle" user.
Amend the "/etc/security/limits.d/90-nproc.conf" file as described below. See MOS Note [ID 1487773.1]
# Change this * soft nproc 1024 # To this * - nproc 16384
Set secure Linux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.
Once the change is complete, restart the server.
Create the directories in which the Oracle software will be installed.
mkdir -p /u01/app/oracle/product/11.2.0/db_1 chown -R oracle:oinstall /u01 chmod -R 775 /u01
Login as root and issue the following command.
Login as the oracle user and add the following lines at the end of the ".bash_profile" file.
# Oracle Settings TMP=/tmp; export TMP TMPDIR=$TMP; export TMPDIR ORACLE_HOSTNAME=ol6-112.localdomain; export ORACLE_HOSTNAME ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME ORACLE_SID=DB11G; export ORACLE_SID 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=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.
DISPLAY=<machine-name>:0.0; export DISPLAY
Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.
Proceed with the installation of your choice. The prerequisites checks will fail for the following version-dependent reasons:
- 126.96.36.199: The installer shows multiple "missing package" failures because it does not recognize several of the newer version packages that were installed. These "missing package" failures can be ignored as the packages are present. The failure for the "pdksh" package can be ignored because we installed the "ksh" package in its place.
- 188.8.131.52: The installer should only show a single "missing package" failure for the "pdksh" package. It can be ignored because we installed the "ksh" package in its place.
- 184.108.40.206: The installer shows no failures and continues normally.

If you are doing an installation for an Enterprise Manager repository, remember to do an advanced installation and pick the ALT32UTF8 character set.

Edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'.
"error code 35" : The machine name in the "/etc/hosts" file is not correct. It needs an entry for the loopback adapter (localhost) and the machine name. If you are using DNS for name resolution, you still need the loopback adapter reference in this file.
"error code 37" : The DNS not working properly. You may also get this error is the "/etc/hosts" file is not configured correctly.
"sqlplus: error while loading shared libraries: libclntsh.so.11.1" : The prerequisites have not been met. Work through them again. Specifically, make sure the "gcc" package has been installed.
Listener fails to start - Typically this is due to incorrect name resolution. Make sure the "/etc/hosts" and/or DNS is configured correctly.
Linking errors - Almost always due to missing prerequisites. Review the setup sections.
