Oracle Database 11g Release 2 (11.2) Installation On Oracle Linux 5

This article describes the installation of Oracle Database 11g Release 2 (11.2) (64-bit) on (64-bit). The article is based on a server installation with a minimum of 2G swap, secure Linux disabled. Oracle recommend a default server installation, but for these installations the following package groups installed:

GNOME Desktop Environment

Editors

Graphical Internet

Text-based Internet

Development Libraries

Development Tools

Server Configuration Tools

Administration Tools

Base

System Tools

X Window System

An example of this type of Linux installations can be seen . Alternative installations may require more packages to be loaded, in addition to the ones listed below.

Download Software

Download the following software.

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

Unpack Files

Unzip the files.

# 11.2.0.1unzip linux.x64_11gR2_database_1of2.zipunzip linux.x64_11gR2_database_2of2.zip#11.2.0.2unzip p10098816_112020_Linux-x86-64_1of7.zipunzip p10098816_112020_Linux-x86-64_2of7.zip#11.2.0.3unzip p10404530_112030_Linux-x86-64_1of7.zipunzip 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  localhost192.168.2.181   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 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 = 1fs.aio-max-nr = 1048576fs.file-max = 6815744kernel.shmall = 2097152kernel.shmmax = 536870912kernel.shmmni = 4096kernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500net.core.rmem_default = 262144net.core.rmem_max = 4194304net.core.wmem_default = 262144net.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 = 1fs.aio-max-nr = 1048576fs.file-max = 6815744kernel.shmall = 2097152kernel.shmmax = 536870912kernel.shmmni = 4096# semaphores: semmsl, semmns, semopm, semmnikernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500net.core.rmem_default=4194304net.core.rmem_max=4194304net.core.wmem_default=262144net.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   2047oracle              hard    nproc   16384oracle              soft    nofile  4096oracle              hard    nofile  65536oracle              soft    stack   10240

Install the following packages if they are not already present.

# From Oracle Linux 5 DVDcd /media/cdrom/Serverrpm -Uvh binutils-2.*rpm -Uvh compat-libstdc++-33*rpm -Uvh compat-libstdc++-33*.i386.rpmrpm -Uvh elfutils-libelf*rpm -Uvh gcc-4.*rpm -Uvh gcc-c++-4.*rpm -Uvh glibc-2.*rpm -Uvh glibc-common-2.*rpm -Uvh glibc-devel-2.*rpm -Uvh glibc-headers-2.*rpm -Uvh ksh*rpm -Uvh libaio-0.*rpm -Uvh libaio-devel-0.*rpm -Uvh libgomp-4.*rpm -Uvh libgcc-4.*rpm -Uvh libstdc++-4.*rpm -Uvh libstdc++-devel-4.*rpm -Uvh make-3.*rpm -Uvh sysstat-7.*rpm -Uvh unixODBC-2.*rpm -Uvh unixODBC-devel-2.*rpm -Uvh numactl-devel-*cd /eject

Create the new groups and users.

groupadd oinstallgroupadd dbagroupadd opergroupadd asmadminuseradd -g oinstall -G dba,oper,asmadmin oraclepasswd 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 alteration can be done using the GUI tool (Applications > System Settings > Security Level). Click on the SELinux tab and disable the feature. If SELinux is disabled after installation, the server will need a reboot for the change to take effect.

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

Create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/oracle/product/11.2.0/db_1chown -R oracle:oinstall /u01chmod -R 775 /u01

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 SettingsTMP=/tmp; export TMPTMPDIR=$TMP; export TMPDIRORACLE_HOSTNAME=ol5-112.localdomain; export ORACLE_HOSTNAMEORACLE_UNQNAME=DB11G; export ORACLE_UNQNAMEORACLE_BASE=/u01/app/oracle; export ORACLE_BASEORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOMEORACLE_SID=DB11G; export ORACLE_SIDPATH=/usr/sbin:$PATH; export PATHPATH=$ORACLE_HOME/bin:$PATH; export PATHLD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATHCLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

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

Proceed with the installation of your choice. You can see the type of installation I performed by clicking on the links below to see screen shots of each stage.

Post Installation

Edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'.

DB11G:/u01/app/oracle/product/11.2.0/db_1:Y

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.
