Abstract
A method, system, and computer program product are provided for operating a relational database management system (RDBMS). In order to operate a RDBMS, information is read from a first execution plan in response to an execution request for a second individual database statement of a second sequence of database statements. The information is processed and pool resource requirements for execution of further individual database statements of the second sequence of database statements are evaluated. A preparation request is sent for pool modification based on the evaluated pool resource requirements to an asynchronous pool preparation queue. Then the second individual database statement of the second sequence of database statements is executed. The information indicative of the progression of execution of the second individual database statement is stored in a position register.
