Installation guide of Oracle Database 11g Release 2 on Linux and Windows PART 1

In this I am going to explain in detail about installation of DATABASE on LINUX
As we all know Database installation is easy task on Windows. On other hand Linux is little complex as we need to do many  step before installation.

Step1:- 

Download the DB setup from  https://www.oracle.com/downloads

Step2:- 
After downloading the setup. We need to prepare our OS (windows and linux)

1) Make an entry in "/etc/hosts" for linux and "C:\Windows\System32\drivers\etc\hosts" for windows like below :-
     127.0.0.1       localhost.localdomain  localhost
     XXX.XXX.XXX.XXX         test.domain            test

 Where XXX.XXX.XXX.XXX is IP of your machine.

2) No Need to do anything for windows After this. On linux you need to check the packages. Below are the packages that should be there in the Linux server.

 For Linux : You can create all the packages by using oracle-validated. For this follow instruction at http://public-yum.oracle.com .
               e.g. # yum install oracle-validated
  
This will create everything for you. Your users and evrything.

If you are not going to install it by oracle-validated then below list is for importatnt packages that is needed and below changes in some important files.
  binutils-2.*
  compat-libstdc++-33*
  compat-libstdc++-33*.i386.rpm
  elfutils-libelf*
  gcc-4.*
  gcc-c++-4.*
  glibc-2.*
  glibc-common-2.*
  glibc-devel-2.*
  glibc-headers-2.*
  ksh*
  libaio-0.*
  libaio-devel-0.*
  libgomp-4.*
  libgcc-4.*
  libstdc++-4.*
  libstdc++-devel-4.*
  make-3.*
  sysstat-7.*
  unixODBC-2.*
  unixODBC-devel-2.*
  numactl-devel-*

Note:- for windows no need to anything. 

Step3:- 

Go to /etc/sysctl.conf and amend the changes in /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=262144
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048586

After setting the changes you need to run "/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

Step4:-  

If you havn't run ORACLE_VALIDATE then Create the new groups and users.

Check

Also for linux one more change is needed.Set secure Linux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.

SELINUX=permissive
Note:- for windows please turn down the Firewall of the system and make sure directories having good permisons for read and write.


Step5 :- Log into the OS and set DISPLAY for LINUX.


Step 6:- Now go to the setup and unzip the setup and for windows simply double click on runInstaller.
and for linux just go to the directory by using CD and run ./runInstaller.

I will update second blog with images for complete installation.
