Techniques described herein relate to automatic upstream service resumption after downstream system failure. An automatic resumption module may be configured to monitor a downstream endpoint (of a problematic downstream service provider) and determine when it again successfully can process requests by periodically processing inbound requests (e.g., from suspended upstream service providers) and automatically re-enabling upstream endpoints for the suspended upstream service providers in the case of success. The automatic resumption module may start a trickle feed timer for each upstream endpoint to allow messages to be processed at a configured retry rate while the upstream endpoint remains suspended. The trickle feed timer may be configured to start upon the triggering of a circuit breaker for the involved downstream service. When downstream endpoint invocation succeeds, the automatic resumption module can resume all upstream endpoints associated with the downstream endpoint.

Automatic upstream service resumption after downstream system failure

Techniques described herein relate to automatic system suspension based upon downstream system failure in service-oriented architecture (SOA) applications. A system management module of a SOA system may be configured to detect a problem with a downstream service provider involved with a SOA application, and in response, automatically suspend particular processing within the application to prevent requests that may end up at the downstream service provider from entering the SOA application. The system management module may implement a circuit breaker module that maintains a circuit breaker structure specific to a downstream endpoint leading to a downstream service provider. Upon a triggering of a circuit breaker for a downstream endpoint, one or more upstream service providers are identified as associated with faulted traffic causing the triggering, and the system management module can automatically cause further traffic from these upstream service providers to be suspended.

Automatic targeted system suspension based upon downstream system failure detection

Systems and methods of SOA performance tuning are provided. In accordance with an embodiment, one such method can comprise monitoring a plurality of processing stages, calculating a processing speed for each of the processing stages, and tuning a slowest processing stage of the plurality of processing stages.
