This symposiumproceedings contains 26 papers dealing with reliability problems in distributeddatabasesystems.(DDBS). These problems seem to appear often as paradoxes, as the reason for the distribution is the reduction of vulnerability associated with failures in simple centralized computers. The replication of hardware permits some parts of the system to operate while other parts have failed. The replication of software and major parts of databases is considered in order to reduce the communication overhead. Issues of error confinement, optimistic concurrency control and nested multilevel transactions, two-phase locking (2PL), read only transactions and transaction atomicity are discussed. Three papers are in extended abstract form and two in abstract form only.

It is shown that the optimistic approach to concurrency control lends itself naturally towards a design of a reliable distributeddatabase system. In addition, the functions of concurrency control, integrity control, and atomicity control can be integrated. This integration can provide a higher degree of concurrency and continuity of operations.

Evidence of distribution, such as work distribution, distributed file and data base management, etc. , creates a number of reliability issues that must be addressed by the system software. Many of these are similar to problems arising in centralized systems.however, there are a number of new issues as well as complications of common ones. Some of the specific reliability issues raised by the organizational and operational characteristics of fully distributed processing systems.(FDPS's) are outlined. It is important to bear in mind that decision making is decentralized and that there are no permanent master-slave relationships in an FDPS.

Recovery provisions in a distributed system are considered and issues of the reliability of software design are examined. As there is no generally valid system for recovery provision design, the provisions are reviewed. The cost of testing, documentation, operator training, and interface administration that are required for proper operation of the provisions are considered.

The design of a distributed processing system must include methods to handle distributed data retrieval. A considerable amount of research has been devoted to the development of algorithms that provide this function. A survey of this research is presented and a taxonomy is introduced that highlights the significant differences among the algorithms.

Many of the special problems in distributed computing relate to the handling of exceptional conditions. In a distributed program exceptions occur as a result of transmission errors and partial failures. Any exceptional condition that arises must be handled if distributed programs are to be robust. Various approaches are examined towards providing exception handling mechanisms for distributed applications which were incorporated into several experimental distributed operating systems. These operating systems.all support the notion that the primary software structuring tool for applications will be a collection of cooperating programs (processes) mapped onto a set of loosely coupled processors.
