When data, such as tool data, is commonly accessible, there is a danger that concurrent user processes will make overlapping modifications and leave the data in an incomplete or incomprehensible state. The invention provides a locking mechanism to guard against this. The lock objects are maintained in pool or repository. Two types of lock objects are provided; shareable locks that may be shared by many user processes and permit only read access to the locked data, and exclusive locks, useable by only one user process at a time, that permit the owning process to modify the locked data.
Lorsque des données, p. ex. des données outils, sont accessibles en commun, il y a danger que des processus utilisateurs concurrents effectuent des modifications chevauchantes et laissent les données dans un état incomplet ou incompréhensible. L'invention offre un mécanisme de verrouillage pour empêcher ces situations. Les verrous sont conservés dans un centre de ressources commun. Deux types de verrous sont offerts : les verrous partageables, que peuvent partager de nombreux processus utilisateurs et qui permettent l'accès des données verrouillées seulement en lecture, et les verrous exclusifs, accessibles à un seul processus utilisateur à la fois, qui permettent à ce dernier de modifier les données verrouillées.
