oracle10g数据库test采用 集群配置，两个实例：test1@192.168.1.1 以及test2@192.168.1.2
部署的服务单独访问任一个实例均启动成功。
但是采用集群url方式就提示Network adapter could not establish the connection
集群数据库url为：
jdbc:oracle:thin:@(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 = yes) ) (CONNECT_DATA = (SERVICE_NAME = test) (FAILOVER_MODE = (TYPE = SELECT) (METHOD = PRECONNECT) (RETRIES = 20) (DELAY = 60)) ) )
说明：还部署了其他服务进行集群访问的，均正常，就最新的服务器上最新部署的服务不可访问。
