Abstract: A method, system, and computer program product for service failover and failback using ESB are provided in the illustrative embodiments. A determination is made, by a processor at a first data processing system, whether a service being requested in a request can be provided from a failover provider system. An event log record is used to determine whether a connection failure event occurred with a primary provider system of the service. An evaluation is made whether the request can be routed to the failover provider system. The request is routed to the failover provider system.

Abstract: A network management system determines whether end-to-end network paths are working, using network probes. A network component is deemed suspicious if included in every failed path, and deemed working if included in at least one working path. From the set of suspicious network components and the set of working components, a set of failed network components is deduced. The sets may be refined using SNMP to test visible components. In one embodiment, the set of failed network components is deduced by eliminating, from the set of suspicious network components, every network component that is included in the set of working network components. This may be done by finding the intersection of two sets: the set of suspicious network components, and the complement of the set of working network components, where the complement is with respect to the set of all network components.
