针对轨道交通集群调度系统中数据库连接池参数一次性设定后不可修改的问题,设计面向多客户端的数据库连接池动态分配策略。通过使用动态分配算法,根据每个客户端访问频率的不同为当前客户端分配最优连接数,从而达到提高系统资源利用率的目的。实验结果表明,该动态分配策略能够缩短连接池响应时间,提高系统运行效率。 Aiming at the issue that the database connection pool parameters can not be modified after one-time setting of the parameters of the database connection pool in the rail transportation cluster dispatching system, the dynamic allocation strategy of database connection pool for multi-client is designed. By using a dynamic allocation algorithm, the optimal number of connections for the current client is allocated according to the access frequency of each client, so as to achieve the purpose of improving system resource utilization. Experimental results show that the dynamic allocation strategy can shorten the connection pool response time and improve the system operating efficiency.
