oracle在11g中引入了database resident connection pooling(DRCP)。在此之前,我们可以使用dedicated 或者share 方式来链接数据库,dedicated方式是oracle数据库默认的链接方式,无需过多的配置,而且关于dedicated的bug也是非常少的,因此,通常情况下,建议使用dedicated方式来链接数据库。但是,在服务器资源有限,并且同时连接数据库...
If a connection is established or created it should be added to the connection pool, and if that connection is closed it should be removed in connection pool; while it is open I can use it again and again. While reading these tutorials and explanations about connection pooling I have some ...

连接池使应用程序能够使用来自不需要为每个用途重新建立的连接池中的连接。 可以使用“ODBC 数据源管理器”对话框的“连接池”选项卡来启用和禁用性能监视。 双击驱动程序名称以设置连接超时期限。 在驱动程序级别,连接池通过 CPTimeout 注册表值启用。 通过此选择性的按驱动程序启用,系统管理员只需为可支持该功能的...
Connection pooling is a technique used to improve performance in applications with dynamic database driven content. Opening and closing database connections may not seem like a costly expense but it can add up rather quickly. Let's assume it takes 5ms to establish a connection and 5ms to execut...
Database Resident Connection Pooling Memory used = 100 X (400 KB + 4 MB) + (5000 X 35KB)= 615 MB 100个共享服务进程能够应付5000个并发客户连接,而为了管理这5000个并发连接,只需给DRCP broker分配175M的内存空间即可。 DRCP 配置 SQL> exec dbms_connection_pool.configure_pool(maxsize=>10,inactivit...
Since the connection pooling is handled inside of Active Record by default, all application servers (Thin, Puma, Unicorn, etc.) should behave the same. The database connection pool is initially empty. As demand for connections increases, it will create them until it reaches the connection pool...
