net.core.wmem_default = 262144
net.core.wmem_max = 1048586

To see, and read new config

# sysctl -p
# sysctl -a



edit /etc/security/limits.conf  to add below

oracle soft nproc 2047
oracle hard nproc 16384

oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32768

Necessary permision on the partition where you want to install the software

# mkdir /D01
# chown -R oracle:dba /u01


# cd /software/database
# ./runInstaller

and follow the steps,
