Techniques are described herein for handling lock- related inconsistencies. As mentioned above, such inconsistencies occur when two or more sets of lock information, relating to the same resource, convey inconsistent information about locks requested and/or granted on that resource. In general, the techniques involve causing the locally-stored lock information about a resource to be sent to the master node of the resource . The master node of the resource compares the lock information thus received against the lock information maintained by the master node. Based on the comparison, the master node determines how to resolve the lock-related inconsistency, and sends messages to those nodes that need to change their local lock information for the resource. Once all of the lock information has been made consistent, the resource made available for access. Because the lock- related inconsistency is resolved without restarting nodes, the availability of the resources is improved .
L'invention concerne des techniques servant à gérer des incohérences liées au verrouillage. De telles incohérences se produisent lorsque deux ou plusieurs jeux d'informations de verrouillage concernant la même ressource contiennent des informations incohérentes sur des verrouillages requis et/ou accordés sur cette ressource. En général, selon ces techniques, les informations de verrouillage enregistrées localement sur une ressource sont envoyées au noeud maître de la ressource. Le noeud maître de la ressource compare les informations de verrouillage ainsi reçues aux informations de verrouillage qu'il conserve. En fonction de cette comparaison, le noeud maître détermine comment résoudre l'incohérence liée au verrouillage et envoie des messages aux noeuds qui doivent modifier leurs informations de verrouillage locales pour la ressource concernée. Une fois que toutes les informations de verrouillage ont été rendues cohérentes, la ressource devient accessible. Comme l'incohérence liée au verrouillage est résolue sans redémarrer des noeuds, la disponibilité des ressources est améliorée.
