我在执行导出的时候遇到的错误：

EXP-00056: 遇到 ORACLE 错误 12154
ORA-12154: TNS: 无法解析指定的连接标识符
EXP-00000: 导出终止失败

导出语句为：

exp 用户名/密码@orcl_192.168.1.3 file=./test.dmp log=test.log owner=test

查了好多资料说是tnsnames.ora中配置的问题。我机子的是

# tnsnames.ora Network Configuration File: E:/oracle/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

ORCL =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.3)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
)
sqlnet.ora里面是

# sqlnet.ora Network Configuration File: E:/oracle/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.

# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.

SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

listener.ora里面是：

# listener.ora Network Configuration File: E:/oracle/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = E:/oracle)
      (PROGRAM = extproc)
    )
)

LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.3)(PORT = 1521))
    )
)

帮忙看看哪里有错误，谢谢。
