May be you have configured a Tomcat Datasource Resource in your server.xml or context.xml in your ${CATALINA_BASE}/conf directory. So, whenever tomcat starts it tries to create the connection pool for your datasource and it is not able to communicate to the db server host. This is highly possible if you don't use mysql in your application
