Abstract: A method of operating a transaction server for use with trace components, providing an execution cost for each trace component, receiving input selecting one or more trace components, running the transaction server with each selected trace component active, monitoring the execution cost of each selected trace component, and providing an updated execution cost for each trace component. The method can also be extended to provide an execution cost for one or more combinations of trace components monitoring the execution cost of any selected trace component combination, and also to provide an updated execution cost for each trace component combination. The method can further comprise maintaining a record of the execution cost of each selected trace component and transmitting the record to a different transaction server, thereby sharing knowledge between connected systems.

Abstract: A system for tracking register and/or storage area assignments and warning a programmer of potential assignment errors. More specifically, the system tracks programmer assignments to registers and storage areas and determines if a register or storage area has been modified prior to a call to a program or process external to the source code being examined. The system notes whether a modified register or storage area is restored to its original value subsequent to the external call. If the register or storage area has not been restored, the system displays a warning of a possible assignment error.
