Consider a computing cluster c

Consider the following two alternatives:asymmetric cluster-ing and parallel clustering.With asymmetric clustering,one host runs the database application with the other host simply monitoring it.If the server fails,the monitoring host becomes the active server.This is appropriate for providing redundancy.However,it does not utilize the potential processing power of both hosts.With parallel clustering,the database application can run in parallel on both hosts.The difficulty implementing parallel clusters is providing some form of distributed locking mechanism for files on the shared disk.
