[GIS program] WebGIS DL : 0: 数据库连接在WebGIS开发中的应用颇为频繁．而由于多用户并发操作以及网络软硬件条件等方面的影响，连接的速度往往不尽如人意。文中利用JDBC技术．在WebGIS中设计并实现了基于Oracle数据库和Java AppJet／ServJet网络模式的数据库连接池，从而大大提高了数据库连接的效率，同时还可以通过连接池自身的管理机制来监视数据库连接的数量和使用情况。-Database connection in WebGIS application development rather frequently. And as multi-user concurrency, and network hardware and software conditions, and other effects, the connection speed is often unsatisfactory. The paper uses the JDBC technology. Designed and implemented in WebGIS based on Oracle database and Java AppJet/ServJet network model database connection pool, thus greatly improving the efficiency of database connection, but also by its own connection pool management mechanism to monitor the number of database connection and use of .
