Download the package using rpm –ivh Package-name.


Now edit the following file & add these line:- 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

/sbin/sysctl –p Edit the below File and change the following:- vi /etc/sysconfig/selinux

# This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=permissive

Disable Firewall

systemctl stop firewalld systemctl stop firewalld

Create oracle installation directory:-

mkdir -p /u01/app/oracle/product/12.1.0/db_1 chown -R oracle:oinstall /u01 chmod -R 775 /u01


Edit the Profile Parameter file:- vi /etc/security/limits.conf

oracle soft nofile 1024 oracle hard nofile 65536 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft stack 10240 oracle hard stack 32768

Enable it to all the users:-

vi /etc/security/limits.d/20-nproc.conf * soft nproc 1024 to * - nproc 16384

Finally Edit .bash_profile :-

export ORACLE_UNQNAME=orcl export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1 export ORACLE_SID=orcl export PATH=/usr/sbin:$PATH export PATH=$ORACLE_HOME/bin:$PATH
