=====================Check RAM =======================

[root@test ~]# grep MemTotal /proc/meminfo
MemTotal:        4048820 kB
[root@test ~]#
/*
 We need at least 1GB of physical RAM.
 In my case I have more than 1GB.
*/


=============Check SWAP space===============================

[root@test ~]#
[root@test ~]#  grep SwapTotal /proc/meminfo
SwapTotal:       3071996 kB
[root@test ~]#

/*
 RAM between 1GB and 2GB then Swap = 1.5 times the size of RAM
 RAM between 2GB and 16GB then Swap = equal to the size of RAM
 RAM more than 16GB then Swap Size = 16GB
 Since my RAM is near by 3GB, so I have 3GB of Swap Size.

*/


===================================Check resolution ======================
/*
 To install Oracle 11g Release 2 your system should be running
 on at least 1024x768 screen resolution.
*/

# xdpyinfo | grep 'dimensions:'
dimensions:    1024x760 pixels (271x203 millimeters)

====================Cehck TMP space=================================


[root@test ~]#
[root@test ~]# df -h /dev/shm/
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           2.0G   76K  2.0G   1% /dev/shm
[root@test ~]#

Resize tmp

 #mount -t tmpfs tmpfs -o size=1500m /dev/shm

exp

[root@test ~]# df -h /dev/shm/
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           2.0G   76K  2.0G   1% /dev/shm
[root@test ~]# mount -t tmpfs tmpfs -o size=2100m /dev/shm
[root@test ~]#
[root@test ~]# df -h /dev/shm/
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           2.1G     0  2.1G   0% /dev/shm
[root@test ~]#
[root@test ~]#

/*
  You need to have at least 1GB of space in the /tmp directory.
  Make sure you have 1GB in the column "Avail" in the above output.
  In my case I have 2.1G space available in /tmp.

=======================Make entry Kernal parameter to Support Oracle======================


Open /etc/sysctl.conf and add the following lines:

net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 2147483648
kernel.shmall = 2097152
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 1048576
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576

Note: You may find the parameters mentioned above already present in the /etc/sysctl.conf file.
If they have a value lower then mentioned above then make sure you change it,
but if they have a larger value then perhaps its safe to leave it as is.

============================To make effect kernal parameters======================


-- Make the kernel parameters changes effective immediately:


[root@test ~]# /sbin/sysctl -p



========================= Set the shell limits for the user Oracle=========================

Open /etc/security/limits.conf and add these lines.

vi /etc/security/limits.conf

oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  4096
oracle              hard    nofile  65536
oracle              soft    stack   10240

save with
:wq!

Where "nproc" is the maximum number of processes available to the user and "nofiles" is the number of open file descriptors.





=======================Setup User and groups that we will use as Oracle owner and the groups that it will need for installing and managing Oracle=======================


/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/groupadd oper
/usr/sbin/useradd -g oinstall -G dba,oper oracle
/usr/bin/passwd oracle

====================Create directories where the Oracle Software and database will be installed.========================

[root@test mail]# mkdir -p /u01/app/oracle/product/11.2.0/db_1
[root@test mail]# chown -R oracle:oinstall /u01
[root@test mail]# chmod -R 0775 /u01
[root@test mail]#

/*
 The above directory structure is designed to comply with OFA
 (Oracle Flexible Architecture) i.e. a directory structure to
 support multiple oracle software installations.

 ORACLE_BASE=/u01/app/oracle
 -- Base directory for all oracle installations.
*/

===================================

Disable secure linux by editing the /etc/selinux/config file, making sure the SELINUX flag is set as follows:

SELINUX=disabled

/*
If you leave SELINUX=enforcing then you may get an error later while starting sqlplus:
sqlplus: error while loading shared libraries:
/usr/lib/oracle/default/client64/lib/libclntsh.so.11.1: cannot restore segment
prot after reloc: Permission denied

*/

============================================================

Open /etc/pam.d/login and add the following line if it is already not there.

session    required     pam_limits.so

/*
How does ulimit work?

When you login to the Linux machine, the "login" program reads the file /etc/pam.d/login. The following line has been included in this file:    
   
session required pam_limits.so

This line tells the "login" program to load the pam_limits.so module during login. In turn, the pam_limits.so module is configured to read the file /etc/security/limits.conf. Only the root user can edit this file. This file lists those users who can set the ulimit values.

For example, the following lines in /etc/security/limits.conf file


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

*/

=================================================================

The environment is ready for oracle installation. Its time to prepare the oracle installation media now.
Download or Copy the oracle media to the oracle user home directory i.e. /home/oracle.
Once Download/Copy is done unzip the media as follows:
