摘要： In a transaction parallel control method of a DBMS, if a priority of a transaction process accepted from an application is higher than a transaction process of an application being executed or suspended, a conflict is judged between database resources used by the both processes and a transaction process to be suspended or terminated is determined based on types and values of the database resources acquired by the respective processes. After the determined transaction process is suspended or terminated, the transaction process of the application is executed by acquiring a value corresponding to the type of the database resource included in the database resource acquisition schedule information accepted from the application and, after the completion, the suspended transaction is restarted.
