Web Application on AWS and Oracle DB on premise

@xxx

Dear Sir,

We are deploying an apache-tomcat WebApplication in an Amazon Web Service instance (AWS-EC2,  xlarge. ).

The web application needs to access our local Oracle server through a public IP address:port1521.

The webapp was developed in Java and uses ojdbc7.jar, with these properties 

<bean class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" name="DS">

<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>

<property name="username" value="***"/>

<property name="password" value="***"/>

<property name="url" value="jdbc:oracle:thin:@xxx.xxx.xxx.xxx:1521:dbname"/>

<property name="maxIdle" value="1"/>

<property name="maxActive" value="10"/>

</bean>

The application works fine for "non-data intensive" queries. We are working on genomics research, and
