Mobile agent technology has been proposed for various fault-sensitive application areas, including electronic commerce, systems management and active messaging. Recently proposed protocols providing the exactly-once execution of mobile agents allow the usage of mobile agents in these application areas.Based on these protocols, a mechanism for the application-initiated partial rollback of the agent execution is presented in this paper. The rollback mechanism uses compensation operations to roll back the effects of the agent execution on the resources and uses a mixture of physical logging and compensation operations to roll back the state of the agent. The introduction of different types of compensation operations allows performance improvements during the agent rollback.
