2.Metalink上給出瞭如下的解決方案
1）set INBOUND_CONNECT_TIMEOUT_<listenername>=0 in listener.ora
2）set SQLNET.INBOUND_CONNECT_TIMEOUT = 0 in sqlnet.ora of server.
3）stop and start both listener and database.
4）Now try to connect to DB and observe the behaviour
如果不重啓只是進行reload也可以修改成功
通過如下方式驗證是否修改成功
LSNRCTL> show inbound_connect_timeout
修改listener的inbound_connect_timeout參數的方法
方法一:

LSNRCTL> show inbound_connect_timeout
Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521))
LISTENER parameter "inbound_connect_timeout" set to 0
The command completed successfully
LSNRCTL> set save_config_on_stop on #表示修改參數永久生效，否則只是臨時生效，下次重啓監聽又還原爲原來的值了
LSNRCTL> exit
方法二：
修改listener.ora文件，加入: INBOUND_CONNECT_TIMEOUT_LISTENER_NAME=0
