listener 配置小练习之方法二

标签：listener   配置文件   网络服务   oracle   数据库   

作业：1521 1526
环境里存在一个数据库实例A

实现：
1521监听A数据库
A数据库的信息主动注册到1526监听器上
并且通过easy connect和sqlplus sys/oracle@网络服务名 as sysdba 方式验证

下面我想用另一种方式来实现：数据库WDD都是动态向1521  1526注册数据库
1 编辑listener.ora配置文件
LSNR2 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.195.60)(PORT = 1526))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.195.60)(PORT = 1521))
    )
  )

2 编辑tnsnames.ora配置文件
LSNR2 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.195.60)(PORT = 1526))
    )
  )

3 数据库设置local_listener
alter system set local_listener=‘LSNR2‘;这里的LSNR2跟tnsnames里的名字是相同的
4 启动监听
lsnrctl start lsnr2
如果看到如下信息，证明配置正确
Listening Endpoints Summary...
  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=172.16.195.60)(PORT=1526)))
  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=172.16.195.60)(PORT=1521)))
Services Summary...
Service "WDDXDB.dba.oracle.com" has 1 instance(s).
  Instance "WDD", status READY, has 1 handler(s) for this service...
Service "wsweididi.dba.oracle.com" has 1 instance(s).
  Instance "WDD", status READY, has 1 handler(s) for this service...
The command completed successfully
5 客户端验证
客户端tnsnames配置文件
WDD1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.195.60)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = wsweididi.dba.oracle.com)
    )
  )


 
WDD2 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.195.60)(PORT = 1526))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = wsweididi.dba.oracle.com)
    )
  )
验证
1 sqlplus system/oracle@WDD1
2 sqlplus system/oracle@WDD2
3 sqlplus system/oracle@172.16.195.60:1521/wsweididi.dba.oracle.com
4 sqlplus system/oracle@172.16.195.60:1526/wsweididi.dba.oracle.com
