kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128

/usr/sbin/groupadd -g 502 oper
/usr/sbin/useradd -u 500 -m -g oinstall -G dba,oper oracle
id oracle
passwd oracle

Create the installation directory for oracle installation
mkdir -p /u01/oracle
chown -R oracle:dba /u01/oracle
chmod -R 775 /u01/oracle

Create staging directory for oracle installation
mkdir -p /u01/stage

If this database is for demo purpose, so I have to keep with minimum configuration
You can choose File System. But if you are planning for ASM refer configuration details from installation document.
Better to choose the second option this time.
