OBS

Le principe de la validation à 2-phases est le suivant : les inférieurs envoient un message de terminaison au supérieur; lorsqu'il a reçu tous ces messages, le supérieur diffuse un message de préparation à la validation (noté pav); ce message indique à chaque agent inférieur que l'ensemble des partenaires est prêt à valider (toutes les exécutions sont terminées); les inférieurs acquittent cette information (message prêt) ou demandent l'arrêt de la transaction (message abandon); lorsqu'il a reçu tous les messages prêt le supérieur valide localement et diffuse le message de validation (message valider)
