ABSTRACT:
A method, system and apparatus for server failure diagnosis and self-healing in a server farm. An autonomic server farm which has been configured in accordance with the inventive arrangements can include a multiplicity of servers enabled to respond to requests received from clients which are external to the server farm. A resource director such as an IP sprayer or a network dispatcher can be configured to route requests to selected ones of the servers, in accordance with resource allocation algorithms such as random, round-robin and least recently used. Significantly, unlike conventional server farms whose management of failure diagnosis and self-healing relies exclusively upon the capabilities of the resource director, in the present invention, client-assisted failure detection logic can be coupled to the resource director so as to provide client-assisted management of failure diagnosis and self-healing.
