Abstract
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.
