Abstract
The present invention uses feedback to determine the size of an object cache. The size of the cache, (i.e., its budget), varies and is determined based on feedback from the persistent object system. Persistent objects are evicted from the cache if the storage for persistent objects exceeds the budget. If the storage is less than the budget then persistent objects in the heap are retained while new persistent objects are added to the cache.
