Instantiating objects in distributed database systems
Techniques used in a distributed database system for simplifying copying of objects from one database system in the distributed database system to another and establishing the infrastructure necessary for the distributed system in the database systems. One application of the techniques is setting up a cache database system that has a subset of the objects in another database system and establishing a link for redirecting misses between the cache and the other database system. Also included is the infrastructure in the cache and the other database system for an authentication proxy that establishes sessions in the other database system for users to perform operations that have been redirected as a result of a miss in the cache. The techniques require only that the user supply simple descriptions of some of the objects to be copied; the techniques locate the necessary dependent objects and make objects for the infrastructure. Some of these are descriptions of the infrastructure objects that are copied to the cache and executed there and others are objects that are added directly to the other database system.
