Installation of Oracle 11g Release 2(11.2.0.1.0) on OEL 5.4 (Oracle Enterprise Linux).

This post describes STEP-by-STEP Installation of Oracle 11gR2 database software on OEL 5.4

This blog does not cover database creation Process.

So here,The Following Steps:

1. Pre-Installation Tasks
2. Download & Install
3. Post-Installation Tasks
4. Common Installation Errors 

Pre-Installation Tasks. 

1.      Create oracle user account.

       Login as root and create user “oracle which belong to oinstall and dba groups

       Open new Terminal “Right Click on Desktop and Click on Open Terminal”

      # mkdir  -p /oraeng/apps/oracle/product/11.2.0

      # groupadd oinstall 

      # groupadd dba

      # useradd –g oinstall –G dba –d /oraeng/apps/oracle/product/11.2.0 –m oracle

      # passwd oracle

      Changing password for user oracle.

      New UNIX password: oracle

      BAD PASSWORD: it is based on a dictionary word

      Retype new UNIX password: oracle

      passwd: all authentication tokens updated successfully.

Note: “#” sign means that you need executed this command as root user.   

   

      2.   Setting System Parameters

     Edit the /etc/sysctl.conf and add the following lines.

     # vi /etc/sysctl.conf

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

    :wq

 Note: You need reboot system or execute “SYSCTL –P” command to apply above setting

# sysctl –p

Edit the /etc/security/limits.conf file and add the following lines.

# vi /etc/security/limits.conf

oracle           soft    nproc   2047

oracle           hard    nproc   16384

oracle           soft    nofile  1024

oracle           hard    nofile  65536

                        :wq

     3.      Change the ownership and permission

   # chown –R oracle:oinstall /oraeng

   # chown  -R oracle:dba /disk*

   #chmod –R 777 /oraeng /disk*

     4.      Download and Install

                install the required packages using the rpm command;

                        # rpm –ivh <package_name>.rpm

2.      Download the Oracle 11g release 2 software from ORACLE WEBSITE.
