    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
