你的服务里面同名的毕薯服务太多了,把重名的删掉试试。有一个服务就可以了手敏者,不用再额外的编写1,2的。拿拿多了就会把计算机搞糊涂了,它不知道该选择哪个服务工作了。 *** 作计算机,咱们必须清楚地 告诉计算机要执行的指令才行！！！！！
如图:
我刚好在测试也是这样子，是tnsnames.ora文件当在Oracle客户端中配置好Net Manager中配置好服务后就可以通过我们配置的网络服务名访问Oracle数据库了，孙手行此配置实质想D:\Oracle\product\10.2.0\client_1\NETWORK\ADMIN\tnsnames.ora中增加了一行配置(由于我的Oracle是安装在D盘薯槐Oracle目录中，具体路径根据安装时选择的路径而定)。
# tnsnames.oraNetwork Configuration File:d:\Oracle\product\则哗10.2.0\client_1\NETWORK\ADMIN\tnsnames.ora
# Generated byOracle configuration tools.
ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ORCL)
)
)
另外，程序不能放在有括号的目录下，应该是上面这类配置文件中都是括号的原因吧
1、检查listener.log日志发现下面错误：
TNSLSNR for 32-bit Windows: Version 10.2.0.1.0 - Production on 20-9月 -2008 10:25:26
Copyright (c) 1991, 2005, Oracle. All rights reserved.
系统参数文件为D:/oracle/product/10.2.0/db_1/network/admin/listener.ora
写入D:/oracle/product/10.2.0/db_1/network/log/listener.log的日志信息
写入D:/oracle/product/10.2.0/db_1/network/trace/listener.trc的跟踪信息
跟踪级念搜别当前为0
以 pid=1704 开始
监听: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=//./pipe/EXTPROC1ipc)))
监听该对象时出错: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=0.5.0.5)(PORT=1521)))
TNS-12545: 因目标主机或对象不存在, 连接失败
TNS-12560: TNS: 协议适配禅姿器错误
TNS-00515: 因目标主机或对象不存在, 连接失败
32-bit Windows Error: 49: Unknown error
不再监听: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=//./pipe/EXTPROC1ipc)))
2、查看Oracle的listener是否启动
C:/Documents and Settings/mengzhaoliang>lsnrctl status
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 20-9月贺高绝 -2008 10:5
0:44
Copyright (c) 1991, 2005, Oracle. All rights reserved.
正在连接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))
TNS-12541: TNS: 无监听程序
TNS-12560: TNS: 协议适配器错误
TNS-00511: 无监听程序
32-bit Windows Error: 2: No such file or directory
正在连接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=0.5.0.5)(PORT=1521)))
TNS-12535: TNS: *** 作超时
TNS-12560: TNS: 协议适配器错误
TNS-00505: *** 作超时
32-bit Windows Error: 60: Unknown error
原来没有启动listener，用“lsnrctl start”命令也不能启动。
C:/Documents and Settings/mengzhaoliang>lsnrctl start
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 20-9月 -2008 10:5

Copyright (c) 1991, 2005, Oracle. All rights reserved.
启动tnslsnr: 请稍候...
TNSLSNR for 32-bit Windows: Version 10.2.0.1.0 - Production
系统参数文件为D:/oracle/product/10.2.0/db_1/network/admin/listener.ora
写入D:/oracle/product/10.2.0/db_1/network/log/listener.log的日志信息
监听: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=//./pipe/EXTPROC1ipc)))
监听该对象时出错: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=0.5.0.5)(PORT=1521))
)
TNS-12545: 因目标主机或对象不存在, 连接失败
TNS-12560: TNS: 协议适配器错误
TNS-00515: 因目标主机或对象不存在, 连接失败
32-bit Windows Error: 49: Unknown error
监听程序未能启动。请参阅上面的错误消息...
3、查看listener.ora的内容：
# listener.ora Network Configuration File: D:/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 0.5.0.5)(PORT = 1521))
)
)
原来本机的ip发生改变后，就出现了上述问题，改变数据库的监听ip地址:
把(ADDRESS = (PROTOCOL = TCP)(HOST = 0.5.0.5)(PORT = 1521))
改成
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
127.0.0.1：也就是目前数据库正在用的ip地址。
4、再次启动oracle的listener
C:/Documents and Settings/mengzhaoliang>lsnrctl start
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 20-9月 -2008 10:5
4:40
Copyright (c) 1991, 2005, Oracle. All rights reserved.
启动tnslsnr: 请稍候...
TNSLSNR for 32-bit Windows: Version 10.2.0.1.0 - Production
系统参数文件为D:/oracle/product/10.2.0/db_1/network/admin/listener.ora
写入D:/oracle/product/10.2.0/db_1/network/log/listener.log的日志信息
监听: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=//./pipe/EXTPROC1ipc)))
监听: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=1521)))
正在连接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))
LISTENER 的 STATUS
------------------------

服务摘要..

例程 "PLSExtProc", 状态 UNKNOWN, 包含此服务的 1 个处理程序...
命令执行成功
启动已经成功，
5.再tnsnames.ora上添加上
ORCL_127.0.0.1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
6、再次用PL/SQL Developer再次连接数据库
出现下面错误：
TNS-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务
再次检查listener.log日志
20-9月 -2008 11:01:54 * (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=orcl)(CID=
(PROGRAM=D:/plsql/plsqldev.exe)(HOST=RUIFEI-EF0ADC98)(USER=mengzhaoliang))) * (ADDRESS=
(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=1267)) * establish * orcl * 12514
TNS-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务
查看listener：
C:/Documents and Settings/mengzhaoliang>lsnrctl services
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 20-9月 -2008 11:1

例程 "PLSExtProc", 状态 UNKNOWN, 包含此服务的 1 个处理程序...
处理程序:

LOCAL SERVER
命令执行成功
7、用sqlplus也出现同样错误：
C:/Documents and Settings/mengzhaoliang>sqlplusscott/mzl@ORCL_127.0.0.1
SQL*Plus: Release 10.2.0.1.0 - Production on 星期六 9月 20 11:15:09 2008
Copyright (c) 1982, 2005, Oracle. All rights reserved.
ERROR:
ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务
8、查看listenser状态：
C:/Documents and Settings/mengzhaoliang>lsnrctl status
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 20-9月 -2008 11:2
6:42

正在连接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))
LISTENER 的 STATUS
------------------------

已使用的参数文件:
D:/oracle/product/10.2.0/db_1/network/admin/sqlnet.ora
TNS-03505: 无法解析名称
9、查看sqlnet.ora内容：
# 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.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
10.把listener.ora的内容：
# listener.ora Network Configuration File: D:/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
)
改成下面的内容：
# listener.ora Network Configuration File: D:/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = orcl)
(ORACLE_HOME = D:/oracle/product/10.2.0/db_1)
# (PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = orcl))
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
)
11、然后关闭、再启动listener
在cmd中执行“lsnrctl stop” 和“lsnrctl stop”命令，再次登陆正常！
C:/Documents and Settings/mengzhaoliang>sqlplus scott/mzl@orcl
SQL*Plus: Release 10.2.0.1.0 - Production on 星期六 9月 20 11:55:47 2008
Copyright (c) 1982, 2005, Oracle. All rights reserved.
连接到:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, OLAP and Data Mining options
SQL>
再次用PL/SQL Peveloper登陆就没有问题了。
完毕!
通过以上步骤我的问题还没解决，然后重启了一下OracleOraDb10g_home1TNSListener服务就行了
