oracle动态注册和静态注册监听器

标签：oracle   客户端   动态   记录   信息   

     oracle动态注册和静态注册的区别：动态监听不需要在listener.ora文件中记录关于数据的任何信息，只需要将监听器的配置信息写入到该文件。例如：

 LISTENER =
 (DESCRIPTION_LIST =
   (DESCRIPTION =
    (ADDRESS=(PROTOCOL = IPC) (KEY=EXTPRO1))
    (ADDRESS=(PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
    )
 )

客户端的tnsnames.ora配置信息，需要加入每个service_name,其他的任何东西不需要改动，例如

 YUCESHI1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = test1)
    )
  )
YUCESHI2 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = test2)
    )
  )
YUCESH3 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = test3)
    )
  )

动态监听步骤：

服务器端配置如下：

1. 设置service_names:

    alter system  set  service_names=test1,test2,test3;

 2. 编写listener.ora文件：

    LISTENER =
   (DESCRIPTION_LIST =
   (DESCRIPTION =
    (ADDRESS=(PROTOCOL = IPC) (KEY=EXTPRO1))
    (ADDRESS=(PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
    )
    )

 3.重新启动oracle实例，这样做才能使service_names生效。（前提是oracle处于open状态下才执行）

   conn /as  sysdba;

   shutdown immediate;

   startup;

客户端配置：

 1.编辑tnsnames.ora,保存后立即生效。

   YUCESHI1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = test1)
    )
  )
YUCESHI2 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = test2)
    )
  )
YUCESH3 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = test3)
    )
  )

以上动态注册配置完毕。以上改为静态注册步骤。

1.只需要在服务器端修改listener.ora配置文件。并且多几个SID_DESC就行了。

配置如下：

LISTENER =
 (DESCRIPTION_LIST =
   (DESCRIPTION =
    (ADDRESS=(PROTOCOL = IPC) (KEY=EXTPRO1))
    (ADDRESS=(PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
    )
 )

##上面是监听器配置部分，下面是数据库配置部分
SID_LIST_LISTENER =
 (SID_LIST =
  (SID_DESC =
   (GLOBAL_DBNAME = test1)
   (ORACLE_HOME = /opt/oracle/product/11.2.0/dbhome_1)
   (SID_NAME = orcl )
  )

  (SID_DESC =
   (GLOBAL_DBNAME = test2)
   (ORACLE_HOME = /opt/oracle/product/11.2.0/dbhome_1)
   (SID_NAME = orcl )
  )

(SID_DESC =
   (GLOBAL_DBNAME = test3)
   (ORACLE_HOME = /opt/oracle/product/11.2.0/dbhome_1)
   (SID_NAME = orcl )
  )

  )

2.重新启动监听：

  su - oracle

   lsnrctl  stop

   lsnrctl  start

配置完成
