Add user Oracle:
/usr/sbin/useradd -u 502 -g oinstall -G dba,oper oracle
Change password for user:
passwd oracle
Add kernel parameters to /etc/sysctl.conf.
 kernel.shmmni = 4096

 net.core.rmem_max = 4194304
 net.core.wmem_default = 262144
 net.core.wmem_max = 1048586
Apply kernel parameters:
/sbin/sysctl -p
Add following lines to set shell limits for user oracle in file /etc/security/limits.conf

Create directory structure:
 mkdir -p   /u01/app/oracle/product/12.1.0
 chown  -R oracle:oinstall /u01/
 chmod  775 /u01/app
Disable selinux  by editing the “/etc/selinux/config” file,
SELINUX=permissive
Install database software
Let’s start with database software installation as oracle user.
su - oracle
Unzip the  database  install files:
unzip linuxamd64_12c_database_1of2.zip
unzip linuxamd64_12c_database_2of2.zip 
[oracle@ora-c7 ~]$ cd  database/

[oracle@ora-c7 database]$ ./runInstaller

During the linking phase, you will see the following error.
    Error in invoking target 'links proc gen_pcscfg procob' of makefile
    '/u01/app/oracle/product/12.1.0.2/db_1/precomp/lib/ins_precomp.mk'.
    See
    '/u01/app/oraInventory/logs/installActions2014-10-29_09-07-03PM.log'

To fix it, do the following:
    rm -rf $ORACLE_HOME/lib/stubs/*
    cp $ORACLE_HOME/rdbms/lib/env_rdbms.mk $ORACLE_HOME/rdbms/lib/env_rdbms.mk.orig
Perform the following modifications:
