SCRIPT DE CONFIGURACIÓN DEL SISTEMA OPERATIVO PARA LA INSTALACION DE ORACLE 10G

Es todo un problema tener que configurar cada vez el Linux (RedHat o Centos) para tenerlo listo para la instalacion de Oracle Database 10g o 11g. Es por eso que he realizado un script para su ejecucion luego de realizar la instalacion el S.O siendo usuario "root".
