Distributed Database Management Systems offer advantages
and new possibilities to centralized database systems.
However, some aspects and issues need to receive further
consideration. Concurrency control is one of these aspects
that has to be improved in order to increase system
performance. Strict Two Phase locking s2pl is the concurrency
control mechanism that is used in most commercial
database systems. The performance of s2pl can be
greatly improved using speculative techniques with speculative
Two Phase Locking algorithms sp2pl. In this paper
we present extensions of the sp2pl algorithm based on Wait
Depth Limited techniques wdl-sp2pl. A comprehensive simulation
model is developed from which the performance of
sp2pl and the wdl-sp2pl's are evaluated. Our analysis also
shows that the new algorithms give a better performance
than sp2pl, maintaining the robustness of sp2pl.
