ORACLE 11G RAC监听配置（实例共享）

最近两天QQ上某网友RAC装完之后，监听怎么配置，下面我就共享一个实例

环境信息

cat /etc/hosts
192.168.1.11     racdb1 
192.168.2.2      racdb1-priv    
192.168.1.12     racdb1-vip     
192.168.1.13     racdb2 
192.168.2.3      racdb2-priv    
192.168.1.14     racdb2-vip     
192.168.1.15     scan-db

在tnsnames.ora 添加

LISTENER_RACDB1，LISTENER_RACDB2，SCAN
vi tnsnames.ora     
LISTENER_RACDB1 =
  (ADDRESS = (PROTOCOL = TCP)(HOST = racdb1-vip)(PORT = 1521))

LISTENER_RACDB2 =
  (ADDRESS = (PROTOCOL = TCP)(HOST = racdb2-vip)(PORT = 1521))

SCAN =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = scan-db)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = db)
    )
  )


su  - oracle

SQL>alter system set local_listener='LISTENER_RACDB1:1521',sid='db1';  
SQL>alter system set local_listener='LISTENER_RACDB2:1521',sid='db2';
SQL> alter system set remote_listener='racscan:1521'; 
SQL> alter system register;

客户端两种方式连接

TNS vip连接方式
RAC =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.12)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.14)(PORT = 1521))
    (LOAD_BALANCE = ON)
    (FAILOVER = ON) 
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = db)
    )
  )

tns racscan连接方式
tns vip 方式
SCAN =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = racscan)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = db)
    )
  )
