Oracle 11g Installation on Fedora 14 (Part 1 - Pre-installation)

OK I'll show how to install oracle on Linux environment.So for this I uses Oracle 11g and Fedora 14x64.So in this post I'll explain about what are the requirements and pre configurations that you need before install oracle on fedora.
Hardware Requirements

• 1 GB of RAM ( minimum )
• More than 3.5 GB hard disk space
• Swap space requirement

Software Requirements

• Operating system requirements

               On Linux x86 and Linux x86-64:

• Asianux 2 SP2
• Asianux 3
• Oracle Linux 4
• Oracle Linux 5
• Red Hat Enterprise Linux 4
• Red Hat Enterprise Linux 5
• SUSE Linux Enterprise Server 10

• Kernel Requirements

• On Asianux 2, Oracle Linux 4, and Red Hat Enterprise Linux 4: 2.6.9 or later
• On Asianux 3, Oracle Linux 5, and Red Hat Enterprise Linux 5: 2.6.18 or later
• On SUSE Linux Enterprise Server 10: 2.6.16.21 or later

•  Configuring Kernel Parameters

               The following parameters should be added to /etc/sysctl.conf as root.

 

• Disable SELinux

                Edit /etc/selinux/config as “SELINUX=disabled”

• Installing required packages

• yum install binutils
• yum install compat-libstdc++-33
• yum install compat-libstdc++-33.i686 
• yum install elfutils-libelf
• yum install elfutils-libelf-devel
• yum install gcc
• yum install gcc-c++
• yum install glibc
• yum install glibc.i686
• yum install glibc-common
• yum install glibc-devel
• yum install glibc-devel.i686
• yum install glibc-headers
• yum install ksh
• yum install libaio
• yum install libaio.i686
• yum install libaio-devel
• yum install libaio-devel.i686
• yum install libgcc
• yum install libgcc.i686
• yum install libstdc++
• yum install libstdc++.i686

• yum install numactl-devel
• yum install sysstat
• yum install unixODBC
• yum install unixODBC.i686
• yum install unixODBC-devel
• yum install unixODBC-devl.i686

• Increasing the swap space temporally ( on LVM2 Logical Volume )

               After adding additional storage to the swap space's volume group, it is now possible to extend it. To do so, perform the following procedure (assuming /dev/VolGroup00/LogVol01 is the volume you want to extend by 256MB):

Disable swapping for the associated logical volume:

 swapoff -v /dev/VolGroup00/LogVol01

Resize the LVM2 logical volume by 256 MB:

 lvresize /dev/VolGroup00/LogVol01 -L +256M  

Format the new swap space:

 mkswap /dev/VolGroup00/LogVol01  

Enable the extended logical volume:

 swapon -v /dev/VolGroup00/LogVol01  

               To test if the logical volume was successfully extended, use cat /proc/swaps or free to inspect the swap space.

•  Other requirements

•  Add the following lines to the "/etc/security/limits.conf" file

   oracle soft nproc 2047  
   oracle hard nproc 16384  
   oracle soft nofile 1024  
   oracle hard nofile 65536  

•  Create new groups and users

 groupadd –g 800 dba  
 groupadd –g 888 oinstall  
 useradd –u 800 –g dba –G oinstall –d /home/oracle oracle  

•  Editing “.bash_profile”

               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=$TMP; export TMPDIR   
 ORACLE_HOSTNAME=oel45.localdomain; export ORACLE_HOSTNAME   
 ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE   
 ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1; export ORACLE_HOME   
 ORACLE_SID=DB11G; export ORACLE_SID    
 ORACLE_TERM=xterm; export ORACLE_TERM    
 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=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH    
 if [ $USER = "oracle" ]; then    
 if [ $SHELL = "/bin/ksh" ]; then    
 ulimit -p 16384    
 ulimit -n 65536    
 else    
 ulimit -u 16384 -n 65536    
 fi    
 fi   

OR

or you can do all the above configurations like this,

 cd /etc/yum.repos.d  
 wget http://public-yum.oracle.com/public-yum-ol6.repo  
 yum install oracle-rdbms-server-11gR2-preinstall  

Now you ready to install.
