Estimating the term…
A distributed computing system includes a number of computers, workstations or other computing machines interconnected by a network. One or more service managers are introduced that provide a management interface to corresponding middleware services. The service manager monitors the corresponding middleware service, as well as the underlying distributed computer environment on which an application process that utilizes the middleware service is executing, and allows the middleware service to operate more efficiently, in response to run-time environmental conditions. A fault-tolerance service manager is provided as a management interface to a fault-tolerance service. The fault-tolerance service manager monitors the fault-tolerance service, as well as the underlying distributed computer environment, to make globally optimal decisions, based on run-time environmental data, and to provide the resulting information to the fault-tolerance service. The fault-tolerance service manager can notify the fault-tolerance service about hazardous network conditions (such as object hosts that may crash soon) and the fault-tolerance service may decide to migrate application objects or take other corrective action. The collected environmental data can be used to determine a health rating of components within the computing environment which can be utilized, for example, to select an optimal machine for migration, or to trigger migration or additional replication in the event the health rating indicates that a failure is expected.
A fault-tolerance method for an application process executing in a distributed computing environment, said fault-tolerance method comprising the steps of:
A method of supporting an application process executing in a distributed computing environment, said method comprising the steps of:
A system for minimizing faults in an application process executing in a distributed computing environment, said system comprising:
A system for minimizing faults in an application process executing in a distributed computing environment, said system comprising:
A system of supporting an application process executing in a distributed computing environment, said system comprising:
A system of supporting an application process executing in a distributed computing environment, said system comprising:
A multi-processor distributed environment for executing an application process in computer readable form, said multi-processor distributed environment further comprising a management software module in computer readable form for managing a middleware service, said middleware service containing functionality that may be accessed by said application process and said management software module collecting environmental information about the multi-processor distributed environment and dynamically adjusting the operation of said middleware service in response to said environmental information.
