<<OCM实验选讲>> 第三课 网络配置 实验

1.配置监听的非默认端口1621。

配置非默认端口的监听, 需要设置local_listener参数, 该参数需要在tnsnames.ora文件进行配置. 由于监听使用了非默认端口, 可用alter system register实时向PMON动态注册.

若listener.ora文件配置的监听名字不是默认的LISTENER, 则启动或停止监听需要显示指定监听名字(lsnrctl start/stop LIS16).

详细配置如下:

[oracle@localhost admin]$ echo $ORACLE_HOME
/home/oracle/oracle/product/10.2.0/db_1
[oracle@localhost admin]$ pwd
/home/oracle/oracle/product/10.2.0/db_1/network/admin
[oracle@localhost admin]$ cat listener.ora
LIS16=
 (DESCRIPTION=
  (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1621))
)
[oracle@localhost admin]$ cat tnsnames.ora
TNS16=
 (DESCRIPTION=
  (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1621))
)


PROD16=
 (DESCRIPTION=
  (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1621))
  ( CONNECT_DATA=(SID=PROD))
)
