Implement efficient connection pool with COM+

WANG Xin-guo,GAO Jing-chang ( College of Computer Science and Technology, Jilin University, Changchun 130012, China)  
To solve the problem that database connection generally influences the performance of large-scale management information system, an efficient solution by using connection pool technology was given, the general principle and implementation techniques of connection pool was given, the implementation of an efficient connection pool was given by using the object pool of COM+ and the ATL provided by(VC++ .) Connection pool can avoid the system spending brought by the frequently creating and destroying of database connection object and can improve the performance of whole system efficiently. Connection pool also presents the advantages of multiple tiers system. Practical test results show that connection pool can permanently improve the database's response efficiency when the number of active connection exceeds 200. By using connection pool, the validity and efficiency of distributed transactions that may contain some active connections can be improved more than two times. By limiting the number of active connections, system crashes owing to too many connections can be prevented.
