1. A networked computer system comprising: a plurality of server computer systems; a load balancer that routes requests to the plurality of computer systems, the load balancer comprising: a failure detection mechanism that detects when one of the plurality of server computer systems fails, the failure detection mechanism further detecting a failure recovery; and a failure notification mechanism that sends a message to at least one of the plurality of server computer systems when the failure detection mechanism detects failure of the one server computer system, wherein the message indicates how much additional work may be expected due to the failure of the one server computer system, the failure notification mechanism further sending a message to at least one of the plurality of server computer systems when the load balancer detects the failure recovery, wherein the at least one of the plurality of server computer systems, in response to the message from the load balancer indicating a failure recovery, adjusts the at least one configuration parameter to normal levels; at least one of the plurality of server computer systems including an autonomic configuration parameters adjustment mechanism that adjusts at least one configuration parameter when the message is received from the failure notification mechanism indicating failure of the one server computer system, wherein the at least one configuration parameter includes: a maximum number of database connections; a maximum number of prepared statements in a cache; and a maximum number of threads; at least one of the plurality of sewer computer systems including a performance measurement mechanism that measures performance of the at least one server computer system before the adjustment of the at least one configuration parameter, that measures performance of the at least one server computer system after the adjustment of the at least one configuration parameter, and that determines whether the adjustment of the at least one configuration parameter improved performance of the at least one sewer computer system.
