Autonomous Management of Clustered Server Systems Using JINI

Abstract. A framework for the autonomous management of clustered server systems called LAMA1 (Large-scale system’s Autonomous Management Agent) is proposed in this paper. LAMA is based on agents, which are distributed over the nodes and built on JINI infrastructure. There are two classes of agents: a grand ordinary LAMAs. An ordinary LAMA abstracts an individual node and performs node-wide configuration. The grand LAMA is responsible for monitoring and controlling all the ordinary ones. Using the discovery, join, lookup, and distributed security operations of JINI, a node can join the clustered system without secure administration. Also, a node’s failure can be detected automatically using the lease interface of the JINI. Resource reallocation is performed dynamically by a reallocation engine in the grand agent. The reallocation engine gathers the status of remote nodes, predicts resource demands, and executes reallocation by accessing the ordinary agents. The proposed framework i...
