Abstract: The present invention is directed to a Mobile Agent (MA) and a method of migrating a MA having a set of partitions from a current host to a target host. The MA comprises a communication module capable of, prior to migrating to the target host, getting information on available resources at the target host. The MA further comprises a partition handler. The partition handler is capable of electing partitions to be dropped by the MA and sending the elected partitions to a Partition Storage Agent (PSA). The partition handler elects the partitions to be dropped from the set of partitions and the information on available resources at the target host. The partition handler is further capable of, after migrating to the target host, downloading new partitions from the PSA.
