Fault-tolerant distributed algorithms that are designed to reach agreement have been the subject of a great deal of recent study, primarily focussed on the Byzantine agreement paradigm. The author explores new paradigms and problems that arise in the context of maintaining agreement, rather than reaching agreement in an isolated instance. The emphasis is on open problem areas rather than on specific solutions.

A two-step structure is proposed for the decision-making process that is needed when multiple versions of software are utilized to combat the effects of design errors. In addition to providing a simple framework for implementing a variety of adjudication strategies, the structure makes it possible to give a uniform description which encompasses the range of published solutions.

A controversial point in designing a distributed system is whether the user or the system should be responsible for taking actions as a consequence of system failures. The author proposes a dynamic configuration scheme for runtime reconfiguration of application software that is more flexible than existing proposals. A description is given of a reconfigurable scheme implemented by the operating system which only requires that software components be virtually connected. The authors demonstrate that the scheme increases the reliability and availability of distributedsystems, and compare and contrast this scheme with other similar proposals.

A replicated database system is a distributeddatabase system in which some data objects are stored redundantly at multiple sites to improve the reliability of the system. Without proper control mechanisms, the consistency of a replicated database system might be violated. A scheme to increase the reliability as well as the degree of concurrency is described. It allows transactions to operate on a data object if more than one token copies are available. The scheme also exploits the fact that, for recovery reasons, there are two values for one data object. Proof that the proposed scheme guarantees consistency is provided. Some of variations of the scheme are discussed.
