Abstract: In many applications using database systems, the conventional method
of transaction processing can not be used. This is on account of lack of
integration and existence of centralized solutions. Such situations exist
within heterogeneous systems, mobile database transactions and time-critical
applications requiring admission on priority for a select group of
transactions. For example, in conventional methods, the deadlock detection is
based on use of delay to cause and watch deadlocks. It generates many
difficulties, such as, (a) high overheads of periodic checking (b)
Non-deterministic nature of the delays, and (c) difficulties to scale-up the
centralized solutions. The existing proposal lacks in local processing for
distributed transactions. The proposed technique uses normal message
communication among peers. The proposal leads to enhanced role for resource
sites. The proposal introduces asynchronous operations in transaction
processing. As a result the detection processes do not wait for occurrences of
time-outs delays. In most cases the technique eliminates the possibility of
occurrence of waiting delays.
