This document is the semestrial report of the Lirmm partner for the Facoma project. It concludes semester 2 - out of 6 - for the project. During this semester, partners from Lirmm and Lgi2p have worked on: i) defining an exception handling system for agents. This work is based on previous work that has been done by these partners on the Sage exception handling system that was adapted to the context of the Facoma pro ject; ii) refining their knowledge and understanding of the Dimax replicated agent environment provided by the Lip6 partner; iii) setting the first elements of a specification of an exception handling system dedicated to agents that evolve in a replication-based environment. Indeed, exception handling and replication are two mechanisms that increase the reliability of an application. Exceptions are situations in which the normal flow of a program cannot continue. Replication prevents an application from suffering from system failures. Exceptions and system failures do not apply to the same situations and therefore are complementary to each other. One of the objective of the Facoma project is to study how an exception handling system and a replication mechanism can combine to increase the reliability of agent-based applications.
