The TPC-W / TPC-App subcommittee worked on TPC-App Version 1.1 definition and implementation clarifications as well as changes related to the TPC Pricing specification. The changes are effective immediately and are incorporated in the latest version of the specification, TPC-App Version 1.1.1 and are available on the TPC Web site.
TPC-App is a Web service benchmark consisting of transactions involving database interactions, durable message queue operations, and displaying ACID properties running against a commercial application server. The primary metrics are Total SIPS (Service Interactions Per Second), SIPS per Application Server, Price Performance (for example $USD/SIPS), and the System Availability Date.
Some clarifications made to the TPC-App specification related to verifying the actual socket and SSL session connection rate. The homogeneity requirement regarding the queuing and messaging functions was relaxed to allow various balanced messaging and queuing product functions. Redundancies in the Full Disclosure Report and Executive Summary reporting requirements were eliminated. Additionally, the allowed tolerances and the target percentages for Web Service Request input values now use a clearer notation. The sample Executive Summary was modified to correctly show the pricing page format as required by the TPC Pricing specification.
