| Abstract: | The multiclass concurrency control algorithm is discussed which can be used to resolve the conflicts between the real time transactions and non real time transactions. The 2PL OS and nested transactions are addressed, and the protocol of 2PL OS applied in nested real time transactions of RTDBS is proposed. In connection with RTDBS, the author has put forward a multiclass concurrency control algorithm that can be applied to resolve the conflicts between the real time transaction and the non real time transaction. The structure of the system and the distribution of its functions are also presented. For different features of 2PL OS and nested transactions, the possible problems and the related protocol with various special properties for 2PL OS and nested transactions are analyzed. |
