A tool for debugging OSF DCE applications

Debugging distributed applications presents many challenges in addition to those found in debugging sequential applications. This paper describes a tool, and the principles underlying it, that has been developed to assist in debugging such distributed applications. Although the tool can also be applied in other environments, this paper primarily describes its application to OSF DCE. Special attention is also given to a facility that has presently been implemented only for OSF DCE, the ability to replay an application, that is, to re-execute it with execution constrained to follow the partial order of an initial execution.
