Oracle当客户端与Oracle服务创建连接后
Oracle当客户端与Oracle服务创建连接后,是客户端与Oracle服务器端直接通信的,此时并不会再跟listener打交道了,这个花了好久才把同事说服,这里通过文档的来记录下。是Oracle产生一个ServerProcess与客户端通信,监听只负责通知oracle有客户端需要连接并且这个连接是合法的或者安全的,通知Oracle你赶紧生产一个ServerProcess来提供服务吧。
文档原文: Database Net Services Administrator's Guide->1 Introducing Oracle Net Services下的
1.2.2 About Oracle Net ListenerOracle Database server receives the initial connection through Oracle Net Listener. Oracle Net Listener,referred to in this document as the listener,brokers a client request,handing off the request to the server. The listener is configured with a protocol address,and clients configured with the same protocol address can send connection requests to the listener. When a connection is established,the client and Oracle server communicate directly with one another. 文档中的图也可以说明:
