请教一下oracle的启动监听问题，谢谢！！

首先是listener。ora的内容
lISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
        (ADDRESS = (PROTOCOL = TCP)(HOST = 100.100.100.100)(PORT = 1521))
     )
       )


SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /oradata/product/9.2.0.4)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = ora9204)
      (ORACLE_HOME = /oradata/product/9.2.0.4)
      (SID_NAME = oracle)
    )
  )

然后是tnsnames。ora的配置单
SMSRemote =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 100.100.100.100)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ora9204)
    )
  )
INST1_HTTP =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = charvi)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = SHARED)
      (SERVICE_NAME = MODOSE)
      (PRESENTATION = http://HRService)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

运行lsnrctl start 后：

问题就出来了：”The listener supports no services“
我要启动监听的目的是因为我在sqlnet.ora中写了限制了特定的IP才可以访问oracle的语句，需要重启监听，但启动不了，也限制不了IP，望大家指点迷津啊～～谢谢

no one can give me a help?

真让我这个小菜鸟失望，原本想请教下这个论坛的高人，结果。。。唉。人就是这样。。。说不清的

监听没有配置
su - oracle以后
使用netca配置监听程序
然后在lsnrctl start  便会启动起来的。。。。
