Object-based systems are composed of objects, which are encapsulation of data and methods. Objects are replicated in order to increase reliability and availability of the systems. Objects aremanipulated only through the methods. In addition, methods are invoked in a nested manner. Wediscuss how to lock replicas of an object for methods in a quorum-based scheme and perform methods on the replicas. First, we extend the quorum concept for primitive read and write methods onsimple objects like files to abstract methods supportedby objects. The quorum size is decided based on a conflicting relation among methods and state update ability of methods.
