| Abstract: | In order to make the Railway Internet Ticketing and Reservation System be better guaranteed, combining with the system characteristics of the distributed memory database and the operational characteristics of the Railway Internet Ticketing and Reservation System, this article analyzed and studied on the memory management strategy and garbage collection mechanism of various JVM ( Java virtual machine ). Taken remaining ticket query service system model as an example, the JVM parameter tuning process was briefly tested and analyzed. The test result showed that the optimized system had better stability and high efficiency. |
