oracle9i rac客户端连接问题！

西藏喇嘛

服务器端：
sun 服务器两台+阵列
oracle9.2.0.6
主机名：
srv1   192.168.1.1
srv2   192.168.1.2

客户端
oracle 9.2.0.1

服务器1  initorcl1.ora配置
*.cluster_database_instances=2
*.cluster_database=true
orcl1.instance_name='orcl1'
orcl2.instance_name='orcl2'
orcl2.instance_number=2
orcl1.instance_number=1
orcl2.local_listener='LISTENER_ORCL2'
orcl1.local_listener='LISTENER_ORCL1'
*.remote_listener='LISTENERS_ORCL'
orcl1.thread=1
orcl2.thread=2

服务器1   listener.ora配置
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = srv1)(PORT = 1521))
      )
    )
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /rdbm/orasrv/product/9.2.0.1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (ORACLE_HOME = /rdbm/orasrv/product/9.2.0.1)
      (SID_NAME = orcl1)
    )
  )


服务器1  tnsnames.ora配置
LISTENER_ORCL1 =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.1)(PORT = 1521))

LISTENER_ORCL2 =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1521))

LISTENERS_ORCL =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.1)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1521))
    )

ORCL1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
      (INSTANCE_NAME = orcl1)
    )
  )

ORCL2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
      (INSTANCE_NAME = orcl2)
    )
  )

ORCL =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.1)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1521))
      (LOAD_BALANCE = ON)
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
      (FAILOVER_MODE=
        (TYPE=select)
        (METHOD=basic)
      )
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

客户端的tnsnames.ora同上

现在出现如下问题：
如果srv1和srv2上的实例orcl1 、orcl2   均UP时，客户端连接执行tnsping orcl正常，连接也正常

如果orcl1或orcl2   down掉其中任何一个后，客户端连接执行tnsping orcl正常，连接也正常

但是此时如果把down掉的实例对应的主机shutdown后，此时客户端连接执行tnsping orcl 非常慢，可能需要几十秒，连接也不正常。不知道这是为什么！！
为什down掉一个实例后连接正常（主动连接另一个实例），但是将down掉实例的那台服务器shutdown后，连接会不正常呢？请指点！！谢谢！！

rac两个节点之间的interconnect用的什么协议:TCP还是UDP?
如果是TCP是有可能，60秒的延迟
