Info

Pattern: Leasing • Context: • Clients use server application resources • Problem: • Resources no longer needed should be released • The lifecycle manager cannot determine when a particular remote object is not used anymore • Solution: • Associate each client’s use of a remote object with a lease • When the lease (or all leases) expire(s), the servant is destroyed by the lifecycle manager • Client can renew the lease • Call operation • Explicit renewal 64 Uwe Zdun, Markus Voelter, Michael Kircher - <strong>Remoting</strong> Patterns.
