Questition: 3. Server-sid Network Configuration 3.1 Create a listener using the default listener name. 3.2 The TCP/IP protocol will be used for all connectionps,Use the machine name (not the IP address) for host. 3.3 This listener will listen on the default port 3.4 Databases will be serviced by this listener. 3.5 Add a second listener,named LSNR2,which will listen on port 1526. 3.6 Set up the PROD1 instance to automatically register with the LSNR2. 3.7 Start both listeners. Reference: Net Services Reference->7 Oracle Net Listener Parameters (listener.ora)
问题:
3.服务器端网络配置
3.1使用默认侦听器名称创建侦听器。
3.2 TCP / IP协议将用于所有连接,使用机器名称(而不是IP地址)作为主机。
3.3此侦听器将侦听默认端口
3.4数据库将由此侦听器提供服务。
3.5添加一个名为LSNR2的侦听器,它将侦听端口1526。
3.6设置PROD1实例,自动向LSNR2注册。
3.7启动两个监听器。
参考:Net Services Reference-> 7 Oracle Net Listener参数(listener.ora)
3.1-3.4 创建默认的监听使用监听名listener,端口号为1521,数据库可以注册到本监听
[oracle@rookie admin]$ cd $ORACLE_HOME/network/admin/ [oracle@rookie admin]$ cat listener.ora LISTENER= (DESCRIPTION= (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcp)(HOST=rookie)(PORT=1521)) (ADDRESS=(PROTOCOL=ipc)(KEY=extproc)))) SID_LIST_LISTENER= (SID_LIST= (SID_DESC= (GLOBAL_DBNAME=PROD3) (ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1) (SID_NAME=PROD3)))
3.5 创建一个监听名字为LSNR2,端口号为1526,需要在原有的listener.ora文件中追加内容:
需要修改监听名,端口号,和key值
[oracle@rookie admin]$ cat listener.ora LISTENER= (DESCRIPTION= (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcp)(HOST=rookie)(PORT=1521)) (ADDRESS=(PROTOCOL=ipc)(KEY=extproc)))) SID_LIST_LISTENER= (SID_LIST= (SID_DESC= (GLOBAL_DBNAME=PROD3) (ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1) (SID_NAME=PROD3))) LSNR2= (DESCRIPTION= (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcp)(HOST=rookie)(PORT=1526)) (ADDRESS=(PROTOCOL=ipc)(KEY=extproc1))))
3.6 需要将PROD1动态注册到LSNR2上:
参考:Reference –> LOCAL_LISTENER参数
SQL> show parameter listener NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ listener_networks string local_listener string LISTENER_PROD1 remote_listener string SQL> alter system set local_listener='(ADDRESS=(PROTOCOL=tcp)(HOST=rookie)(PORT=1526))'; System altered.
3.7 启动两个监听
