配置数据库同时向多个监听进行动态注册

邓辉

1、netmgr创建监听
listener1-->1522
listener2-->1523

[oracle@dbserver admin]$ lsnrctl start listener1

2、创建本地网络服务名
[oracle@dbserver admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

L1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = dbserver)(PORT = 1522))
    )
  )



L2 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = dbserver)(PORT = 1523))
    )
  )

3、配置数据库本地监听注册参数
SQL> alter system set local_listener='L1','L2';
System altered.
SQL> show parameter local

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
local_listener                       string      L1, L2

4、手工注册
SQL> alter system register;

System altered.  

5、查看监听状态
[oracle@dbserver admin]$ lsnrctl status listener1

或者通过配置多个地址列表也可以
[oracle@dbserver admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = dbserver)(PORT = 1522))
      (ADDRESS = (PROTOCOL = TCP)(HOST = dbserver)(PORT = 1523))
    )
  )

SQL> alter system set local_listener='LISTENER';

System altered.

SQL> alter system register;

System altered.
