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

• OTN:  Oracle Database 11g>MOS: Oracle Database 11g>
  

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.

　　

　　
   
　　

　　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
　　

　　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
　　

　　Install the following packages if they are not already present.

cd /media/cdrom/Server
　　
rpm -Uvh binutils-2.*
　　
rpm -Uvh compat-libstdc++-33*

　　Create the new groups and users.

　　

　　
groupadd oinstall
　　
groupadd dba
　　
groupadd oper
　　
groupadd asmadmin
　　

　　
useradd -g oinstall -G dba,oper,asmadmin oracle
　　
passwd oracle
　　

　　Note. We are not going to use the "asmadmin" group, since this installation  will not use ASM.

Additional Setup
　　The following setup tasks must be performed regardless of which setup method  you used previously.
　　Disable secure linux by editing the "/etc/selinux/config" file, making sure  the SELINUX flag is set as follows.

　　

　　
SELINUX=disabled
　　

　　Alternatively, this>　　If you have the Linux firewall enabled, you will need to disable or configure  it, as shown here or here.
　　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.

　　

　　
xhost +
　　

　　Login as the oracle user and add the following lines at the end of the  ".bash_profile" file, remembering to adjust them for your specific  installation.

　　

　　
# Oracle Settings
　　
TMP=/tmp; export TMP
　　
TMPDIR=$TMP; export TMPDIR
　　

　　
ORACLE_HOSTNAME=ol5-112.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>　　

　　

Installation
　　Log into the oracle user. If you are using X emulation then set the DISPLAY  environmental variable.

　　

　　
DISPLAY=:0.0; export DISPLAY
　　

　　Start the Oracle Universal Installer (OUI) by issuing the following command  in the database directory.

　　

　　
./runInstaller

Common Errors

• 　　"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.
