With the success of Internet-based business, there is more and more interest in the availability of systems. Availability indicates that a system continuously provides a use- ful service at any given time. Failure detection and recovery methods are supported for developing application of availability. Requirement on availability may vary with appli- cations and in addition may change over time. For applications to be independent of the change of availability requirement there should be a flexible and extensible architecture for supporting availability management. This paper presents an availability management framework (AMF), which supports the flexible management of availability for large dis- tributed systems using object-oriented framework technologies. We focus on the AMF¡¦s flexibility in order to accommodate changing availability requirements which vary with each application. In addition, this paper describes the result of application of the frame- work to support availability of RFID systems.

Keywords: flexible availability management, object-oriented framework, RFID middleware, failure detection, failure recovery
