Abstract: In assisting migration of data processing resources from a first operating environment to a second operating environment, a migration controller responds to a problem encountered during a migration process by invoking a network-based service to discover migration resources. A service provider makes migration resources available via the network-based service. The migration controller can obtain the latest migration rules and use them to resolve certain migration problems. The cooperation between the migration controller and network-based service can be automated to reduce reliance on manual updating of installed computer programs.

Abstract: A method of determining the state of a cable including at least one electrical conductor, uses a generated test signal and applies it to at least one conductor by a non-contact coupling transmitter. The resulting signal is propagated along the at least one conductor and a non-contact electrical coupling receiver picks up a reflected signal, and compares the reflected signal to expected state signal values for the cable to determine its current state.

Abstract: Provided are a system and method for supporting communication between application programs and the processing of messages by those programs. A table driven approach is used to select appropriate components of modular application programs to process received messages. The selection is carried out in dependence on associations between message types (e.g. request, inform, reply) and other characteristics of the message (e.g. whether the message is an expected reply (as identified by an identifier value). Also used in said selection are dynamic characteristics of the message or the system (e.g. possibly expiry of a timeout, or the state of an application). Rules combine these criteria and determine the conditions for invoking an application program component.Also provided is a mechanism for differentiating between reply messages which are received out of serial sequence but are still current and messages which are invalid.
