第二十一章： Oracle 网络
1、listener 监听器：在oracle server 上启动，负责接收client process 并派生server process ，与client process 建立session
2、建立listener ：通过 netca
3、listener 配置

4、客户端链接
--------本地net服务名：通过netca配置(配置文件：$ORACLE_HOME/network/admin/tnsnames.ora)
1、配置service_name
10:43:24 SQL> show parameter name

------------------------------------ ----------- ------------------------------
db_file_name_convert string
db_name string prod
db_unique_name string prod
global_names boolean FALSE

2、客户端连接

log_file_name_convert string
service_names string prod
SQL>
5、lisenter 注册：告诉listener ，database的instance name 和 service name
1）静态注册：当listener 使用的是非标准端口（1521），在listener.ora的文件里手工注册（添加instance name 和 service name）
2）动态注册：listener 采用的是默认端口（1521），当实例启动时，由pmon 自动将instance name 和service name 注册到listener
