关于10gRAC的VIP

LoveWinter

VIP应该是静态的IP 地址, 但是在failover  switch时,VIP可以
由Oracle自动切换到正常的节点. 因此两个Node的RAC环境
建议配置两个不同的VIP.

客户端的tnsnames.ora  当然需要修改拉.  

例如:

ORCLTEST_RAC =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = test1-vip)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = test2-vip)(PORT = 1521))
    (LOAD_BALANCE = yes)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
      (FAILOVER_MODE =
        (TYPE = SELECT)
        (METHOD = BASIC)
        (RETRIES = 180)
        (DELAY = 5)
      )
    )
  )
