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

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