数据库应用,在许多软件系统中经常用到,是开发中大型系统不可缺少的辅助。但如果对数据库资源没有很好地管理(如:没有及时回收数据库的游标(ResultSet)、Statement、连接 (Connection)等资源),往往会直接导致系统的稳定。这类不稳定因素,不单单由数据库或者系统本身一方引起,只有系统正式使用后,随着流量、用户的增加,才会逐步显露。 -database applications, in many software systems often used, is developing large systems indispensable aids. But if the right database resources are not well managed (eg : no timely recovery database cursor (ResultSet), the Statement connect (Connection), and other resources), will often lead directly to the stability of this system. Such factors of instability, not only by the database system itself or caused side, the official use only, as the flow of users increases, will gradually revealed.

J2EE programmers tend to have a ready
J2EE 程序员一般都有现成的应用服务器所带的JDBC 数据库连接池,不过对于开发一般的 Java Application 、 Applet 或者 JSP、velocity 时,我们可用的JDBC 数据库连接池并不多,并且一般性能都不好。我们可以自己写一个JDBC 数据库连接池。-J2EE programmers tend to have a ready-made application server release the JDBC database connection pool, but for the general development of the Java Application, applet or JSP, velocity, we can use JDBC database connection pool is not over, and generally not a good performance. We ourselves wrote a JDBC database connection pool.
