oracle导入是报错，高手解答

[bunrise]

在导入时报错：ORA-12154: TNS: 无法解析指定的连接标识符
SQLPLUS和PL/SQL连接均正常
配置文件如下：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = e:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
(SID_DESC=
(GLOBAL_DBNAME=orcl)
(SID_NAME=orcl)
(ORACLE_HOME=e:\oracle\product\10.2.0\db_1)
)

)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1523))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)

----------------------------
SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

------------------------
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1523))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORCL)
)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)


弄一下午了，望高手解答！

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1523))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)

把host = 127.0.0.1 换成数据库服务器名称试试
