Abstract
Optimizing approximation of an earliest access time of objects in a datasharing environment by maintaining a global exception list for objects that are accessed by transactions that commit infrequently. The global exception list comprises a time value representing the earliest access time for each object in the global exception list, and an object identifier. The system references the global exception list to determine whether the object is in the global exception list. If the object is in the global exception list, the system uses the time value associated with the object when determining the earliest access time for the object. If not, the system approximates the earliest access time of the object by selecting the most recent access time value from the global exception list, providing more recent access times for objects accessed by transactions that commit frequently.
