外地回来，登录pl/sql出现错误：ORA-12541无监听程序。

检查oracleproduct10.1.0db_1NETWORKloglistener.log：

TNSLSNR for 32-bit Windows: Version 10.1.0.2.0 - Production on 04-1月 -2010 13:38:34

系统参数文件为D:oracleproduct10.1.0db_1networkadminlistener.ora

写入D:oracleproduct10.1.0db_1networkloglistener.log的日志信息

写入D:oracleproduct10.1.0db_1networktracelistener.trc的跟踪信息

跟踪级别当前为0

以 pid=7180 开始

监听: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=\.pipeEXTPROCipc)))

监听该对象时出错: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=pc-xxx.mail.yyy.cn)(PORT=1521)))

TNS-12542: TNS: 地址已被占用

TNS-12560: TNS: 协议适配器错误

TNS-00512: 地址已在使用

32-bit Windows Error: 48: Unknown error

不再监听: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=\.pipeEXTPROCipc)))

Oracle的listener已经启动。
查看oracleproduct10.1.0db_1NETWORKADMINlistener.ora

# listener.ora Network Configuration File: D:oracleproduct10.1.0db_1networkadminlistener.ora

SID_LIST_LISTENER =

(SID_LIST =

(SID\_DESC =
  (SID\_NAME = PLSExtProc)
  (ORACLE\_HOME = D:oracleproduct10.1.0db\_1)
  (PROGRAM = extproc)
)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =
  (ADDRESS\_LIST =
    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
  )
  (ADDRESS\_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = pc-xxx.mail.yyy.cn)(PORT = 1521))
  )
)

)

把(ADDRESS = (PROTOCOL = TCP)(HOST = pc-xxx.mail.yyy.cn)(PORT = 1521))

改为(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))

pc-xxx.mail.yyy.cn是计算机名

127.0.0.1也就是目前数据库正在用的ip地址。

查看oracleproduct10.1.0db_1NETWORKADMINtnsnames.ora

找到下列语句：

ORCL =

(DESCRIPTION =

(ADDRESS\_LIST =
  (ADDRESS = (PROTOCOL = TCP)(HOST = pc-xxx.mail.yyy.cn)(PORT = 1521))
)
(CONNECT\_DATA =
  (SERVER = DEDICATED)
  (SERVICE\_NAME = orcl)
)
