Final Paper ALSAEED Hussain 1 Self Adapting Web Servers Based on Hosted Applications By Hussain Alsaeed H Alsaeed MS candidate in computer science at California State University Chico CA 959290410 USA e mail halsaeed csuchico edu 16 12 2009 Abstract The Internet becomes an integral part of our lives By using web application available through the Internet we are able to do things easily with less time and effort than before This research intends to look into the reliability of a server which hosts web applications The proposed solution works in integrating both an admission control mechanism with the system s resources management The admission control mechanism has been used to control the acceptance of incoming requests to the server at the same time the resources management technique has been used to focus in the CPU adaptation during overload situations I INTRODUCTION The main objective of this research paper is to find a solution for a web serving problem The problem on hand is the overloading of a web server when a hosted application is accessed heavily by clients An application could be hosted on a single web server or on physical or virtual distributed web server instances The goal of this paper is to find an algorithm that will balance the load coming to a single web server based on the types of the hosted applications Final Paper ALSAEED Hussain 2 The problem is encountered in an Oracle WebLogic server 5 which is installed on a Sun machine In this server applications are hosted on virtual clustered instances An application could be hosted in more than one instance The server s load balancing algorithm works on balancing the load between instances but not based on the applications hosted So whenever an instance is overloaded or turned off the server will direct the traffic into another instance hosting the same applications The suggested solution to handle this problem is based on a divide and conquer approach In this approach hosted applications will be
