1 Introduction
1.1 PurposeThe purpose of this Install document is to outline the steps needed to install an Oracle 11g R2 Database server.
The intended audience of this document is an Database Administrator, as well as IT Administrator.
1.2 Document ScopeThis document contains information regarding the installation and basic configuration of a Oracle 11g R2 database server on a OpenSUSE 11 Linux OS. The installation and / or configuration/s of the operating system other than the specified and needed by the Oracle database are not covered within this document.
2 ReferencesThe following are the locations of the repositories from which the installer software can be downloaded as well as the URLs which contains official and unofficial details.

3 Pre installation tasksIn order to allow the execution of all the needed tasks, root access to the OS is needed.
Also is important to verify that the OS firewall settings allows access following ports and protocols
Service Protocol Port
Oracle Database Listner TCP 1521
Oracle Enterprise Manager TCP 80,443
Table 3-3
4 Installation
4.1 Operating System Configuration
4.1.1 The /etc/hosts fileThe hostname of the server must be on top of the "/etc/hosts" file according to this syntax:
<IP_address_of_the_server> <FQDN_of_the_server> <HOSTNAME_of_the_server>
Example :
127.0.0.1 localhost.localdomain localhost <192.168.0.215> <oracle112.binnaris.com> <oracle112>
Edit the "/etc/hosts" file with vi
# vi /etc/hosts
Once added, the "/etc/hosts" file with the IP, FQDN, and hostname, should look as the following example.
# Hosts file# comments..# ....
127.0.0.1 localhost.localdomain localhost 192.168.0.215oracle112.binnaris.com oracle112
~~~
4.2 Defining SWAP spaceWARNING:
Do NOT execute this if the system already has a SWAP file or partition.
Oracle Database requires a swap file or partition which size depends on the amount of the RAM memory installed on the system. The following table describes the relationship between installed RAM and theconfigured swap space requirement:
RAM Swap SpaceBetween 1 GB and 2 GB 1.5 times the size of RAMBetween 2 GB and 16 GB Equal to the size of RAMMore than 16 GB 16 GB
Table 4-4
4.2.1 Creating a swapfileUse "dd" command to create the swapfile. "dd" command requires the size of the file in bytes in it´s parameter "count". Use the following table as a guideline.
RAM Bytes SWAP File size GB / Bytes
dd command to create the swap file && set it as swap for the OS && mounting it
16 or more
16777216 16GB / 16777216 Bytes
# dd if=/dev/zero of=/swapfile bs=1024 count=16777216 && mkswap /swapfile -L swap && swapon /swapfile
8 8388608 8GB / 8388608 Bytes # dd if=/dev/zero of=/swapfile bs=1024 count=8388608 && mkswap /swapfile -L swap && swapon /swapfile
4 4194304 4GB / 4194304 Bytes # dd if=/dev/zero of=/swapfile bs=1024 count=4194304 && mkswap /swapfile -L swap && swapon /swapfile
3 3145728 3GB / 3145728 Bytes # dd if=/dev/zero of=/swapfile bs=1024 count=3145728 && mkswap /swapfile -L swap && swapon /swapfile
2 2097152 (2GB x 1,5) = 2,5GB / 3145728 Bytes
# dd if=/dev/zero of=/swapfile bs=1024 count=3145728 && mkswap /swapfile -L swap && swapon /swapfile
1 1048576 (1GB x 1,5) = 1,5GB / 1572864 Bytes
# dd if=/dev/zero of=/swapfile bs=1024 count=1572864 && mkswap /swapfile -L swap && swapon /swapfile
Table 4-5
4.2.2 Setting the swapfile to be mounted at bootBackup the "/etc/fstab" to "/etc/fstab.bak" file
# cp /etc/fstab /etx/fstab.bak
add the swap file entry in "/etc/fstab"
# echo "### swapfile/swapfile swap swap defaults 0 0" >> /etc/fstab
4.3 Creating Installation MediaBoth zip files MUST be extracted in the target OS in order to avoid the error message "cannot execute binary file " when running the installer script - runInstaller.sh -.
Copy the files "linux.x64_11gR2_database_1of2.zip" and "linux.x64_11gR2_database_2of2.zip" to /tmp directory.
# cp /whatever_path/linux.x64_11gR2_database_1of2.zip /tmp# cp /whatever_path/linux.x64_11gR2_database_2of2.zip /tmp
Extract both files
# unzip /tmp/linux.x64_11gR2_database_1of2.zip# unzip /tmp/linux.x64_11gR2_database_2of2.zip
This will generate a directory named "database" whit all the files needed for installation.
4.4 Installing OS packagesExecute the following command in order to install all the packages required.
Oracle Database dependencies# zypper install binutils gcc gcc-32bit gcc-c++ glibc glibc-32bit glibc-devel glibc-devel-32bit ksh-93t pdksh libaio libaio-32bit libaio-devel libaio-devel-32bit libstdc++33 libstdc++33-32bit libstdc++45 libstdc++45-32bit libstdc++45-devel libstdc++45-devel-32bit libgcc45 libstdc++-devel make sysstat
ODBC Drivers# zypper install unixODBC unixODBC-devel unixODBC-32bit

7 Database Web Administration Console - Enterprise ManagerThe Oracle 11g R2 database server includes a web administration console accessible at:
https://<database_server_FQDN>:1158/em
8 The Database Configuration Assistant ( DBCA ) toolOracle 11g R2 database server has a configuration utility named "dbca". The tool needs a runnig display manager, and can be launched from a console by issuing:
# /opt/oracle/product/11.2.0/db_1/bin/dbca
This tool is mainly used to create new databases. Taking notes of all the information introduced within the wizard about the new database is advised.

Solution B
Run the following commands:
# /opt/oracle/product/11.2.0/db_1/bin/emca -deconfig dbcontrol db -repos drop
