什么地方错了？使不是我的servername错了？
帮帮忙，我刚用oracle不久，真的没有好好寻思过她
以前的太乱，我又整理了一下：
# TNSNAMES.ORA Network Configuration File: E:\Oracle\Ora81\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.

ICKEY_127.0.0.1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = websvr)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = ickey)
      (SERVER = ickey)
    )
  )

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

给你一个我的模板：
RMAN.DTTERP =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.9.36)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = rman)
    )
  )

chao_ping大哥：
     你的模板我这样改的！
ickey_127.0.0.1=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = websvr)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ickey)
)
)
我试了，但毫无用处。我怀疑问题是不是处在别的地方，您说呢？
