摘要:
Memory of a database management system (DBMS) that is running in a virtual machine is managed using techniques that integrate DBMS memory management with virtual machine memory management. Because of the integration, the effectiveness of DBMS memory management is preserved even though the physical memory allocated to the virtual machine may change during runtime as a result of varying memory demands of other applications, e.g., instances of other virtual machines, running on the same host computer as the virtual machine.

摘要:
Memory of a database management system (DBMS) that is running in a virtual or physical machine is managed using techniques that that reduce the effect of memory swaps on the performance of the physical or virtual machine. One such technique includes the steps of determining a swap rate while the database application is in an executing state, and decreasing the size of memory space available to the database application if the swap rate is above a threshold.
