    Abstract: Server time protocol (STP) messages and methods of exchange thereof are provided for facilitating synchronization of processing units of a timing network. The STP messages include exchange time parameters (XTP) commands and responses, and STP control (STC) commands and responses. XTP message exchange processing includes: generating an XTP message command at a first processing unit including a command transmit timestamp field set bythe first processing unit and a command receive timestamp field which is unset by the first processing unit; transmitting the XTP message command to a second processing unit; setting the command receive timestamp field in the XTP command with the time the XTP command is received at the second processing unit; and generating an XTP message response at the second processing unit, the message response including the command transmit timestamp set by the first processing unit and the command receive timestamp set by the second processing unit.

    Abstract: Systems, methods, and products for database system transaction management are provided herein. One aspect provides for annotating via a computing device at least one data object residing on the computing device utilizing at least one transaction tag, the at least one transaction tag being configured to indicate a status of an associated data object; processing at least one database transaction utilizing a transactional memory process, wherein access to the at least one data object is determined based on the status of the at least one data object; and updating the status of the at least one data object responsive to an attempted access of the at least one data object by the at least one database transaction. Other embodiments and aspects are also described herein.

    Abstract: Database system transaction management comprises annotating via a computing device at least one database data object (e.g. table 202, page 203, rows 204 within database 201) residing on the computing device utilizing at least one transaction tag 205, the at least one transaction tag 205 being configured to indicate a status of an associated data object; processing at least one database transaction utilizing a transactional memory (TM) process, wherein access to the at least one data object is determined based on the status of the at least one data object; and updating the status of the at least one data object responsive to an attempted access of the at least one data object by the at least one database transaction. The tag updates may be handled utilizing hardware transaction management (HTM) optimistically lock-free.

    Abstract: Se describen mensajes de protocolo de tiempo de servidor STP y métodos de intercambio de los mismos para facilitar la sincronización de unidades de procesamiento de una red de temporización. Los mensajes de STP incluyen comandos de parámetros de tiempo de intercambio (XTP) y respuestas y comandos de control STP (STC) y respuestas. El procesamiento e intercambio de mensajes de XTP incluyen: generar un comando de mensaje de XTP en una primera unidad de procesamiento que incluye un campo de estampa de tiempo de transmisión de comandos ajustado por la primera unidad de procesamiento y un campo de estampa de tiempo de recepción de comandos que está sin ajustar por la primera unidad de procesamiento; transmitir el comando de mensaje de XTP a una segunda unidad de procesamiento, establecer el campo de estampa de tiempo de recepción de comandos en el comando de XTP con el tiempo en que el comando de XTP es recibido en la segunda unidad de procesamiento y generar una respuesta de mensaje de XTP en la segunda unidad de procesamiento, la respuesta de mensaje incluye la estampa de tiempo de transmisión de comandos establecida por la primera unidad de procesamiento y la estampa de tiempo de recepción de comandos establecida por la segunda unidad de procesamiento.
