RAC的负载均衡有2种方式

RAC的负载均衡有2种方式
1：数据库服务器端 设置remote_listener
2: 客户端tns配置

 

 

一般连接串这么写：
ess_hb_i1=
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 132.35.104.20)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = 132.35.104.22)(PORT = 1521))
    (LOAD_BALANCE = off)
    (FAILOVER=ON)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (FAILOVER_MODE =
        (TYPE = SELECT)
        (METHOD = BASIC)
      )
      (SERVICE_NAME = esshb)
    )
  )
