The disclosure is directed to a method of tracing processing of software instructions associated with a transaction. The method includes writing an access data stream addressed to a receiving application on a remote application server and writing a transaction identifier to the end of the access data stream. The receiving application is configured to read the access data stream and the transaction identifier when an instrumented version of the receiving application is implemented on the remote application server.

System and methods for cross-tier transaction tracing

The disclosure is directed to an application server including memory including an instrumented computer executable application. The instrumented computer executable application includes a first routine including a first set of tracing instructions and external resource access instructions and the instrumented computer executable application includes a second routine. The second routine includes a first segment including a second set of tracing instructions and instructions configured to access the first routine and the second routine includes a second segment including the external resource access instructions.

System and methods for tracing transactions

A system and method for controlling relays. The method may comprise receiving one or more input commands for a plurality of relays, with the plurality of relays including a first relay, and a last relay, initiating actuation of the first relay after receiving the input relay commands, and initiating actuation of the last relay after initiating actuation of the first relay. Initiating actuation of the last relay does not wait for a debounce of the first relay. The method waits a debounce period after initiating actuation of the last relay. The debounce period operates to debounce the last relay and the first relay. One or more second relays may also be included in the debounce sequence. The relays may be latching or non-latching relays. The method may determine if another relay is required to be actuated after initiating actuation of each relay. One of the input commands may include a debounce mode input. A delayed debounce mode debounces the plurality of relays only after the last relay has been actuated. An immediate debounce mode debounces each relay immediately after the relay has been actuated. The system comprises one or more relay drivers coupled to relay control logic, with optional relays coupled therebetween. The relay control logic is operable to receive input commands for the relays, to initiate actuation of the relays without waiting for a debounce of the previous relay. The relay control logic waits a debounce period after initiating actuation of the last relay. The debounce period operates to debounce the last relay and the first and second relays.
