ORA-12154: TNS: 无法解析指定的连接标识符

各位帮忙看看，这是啥问题，tnsping没有问题。但sqlplus连接时指定tnsname就报错，不指定就可以。

检查一下服务名

诊断这类问题。需要查看那些文件？
谢谢！

SERVICE_NAME = ORCL
改成 SID = ORCL 试试

将你解析的HOST=主机名，换成IP地址试下

一般这类问题检查：

客户端：SID ，TNSNAMES.ORA ，SQLNET.ORA

服务器端：LISTNER.ORA ， 数据库是否启动等

这个试过了，没有任何变化。

我就是一台电脑，没有其他机器。
我应该看D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN目录下的sqlnet.ora、tnsnames.ora、listener.ora这几个文件文件吧。

我贴一下内容
【listener.ora】
# listener.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
TRACE_LEVEL_LISTENER = USER
TRACE_FILE_LISTENER = LISTENER1.trc

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = ORCL)
      (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
      (SID_NAME = ORCL)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = F472BD493CA0462)(PORT = 1521))
    )
  )


【sqlnet.ora】
# sqlnet.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\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.

NAMES.DIRECTORY_PATH= (TNSNAMES,ONAMES)




【tnsnames.ora】
# tnsnames.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.


DBRMAN =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = F472BD493CA0462)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = dbrman)
    )
  )

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SID = ORCL)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =

    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )


麻烦各位了，谢谢！
