oracle character collect Configuration mistake

且全部字符中应该为字母和数字混合 错误描述 及 解决 办法 :: ERROR: ora-12541:TNS:没有监听器 1.没有监听程序,或者监听程序没有启动; 解决办法 ::配置监听程序或者 重启监听程序 2.监听程序已经启动,任然报错,说明 监听程序 和 数据库 启动顺序出

且全部字符中应该为字母和数字混合

错误描述  及 解决 办法 ::

ERROR:

 ora-12541:TNS:没有监听器
  1.没有监听程序,或者监听程序没有启动;

           解决办法 ::配置监听程序或者 重启监听程序

  2.监听程序已经启动,任然报错,说明 监听程序 和 数据库 启动顺序出错

          解决办法 :: 保持监听程序开启;重启数据库服务(restart database)

ERROR:
  ORA-12170: TNS: 连接超时
解决办法
::

1.cmd-----ping ip地址 查看网络问题,看能否ping通

2.cmd-----tnsping   ip地址(或者是服务器的实例名SID)如果报“TNS-12535:操作超时”,可能是服务器端防火墙    没有关闭

3.cmd----netstat -na 查看1521端口是否关闭,如果关闭Windows XP中的防火墙设置中将1521端口设为例外

4.cmd----lsnrctl status   lsnrctl是listener-control 监听器的缩写,查看监听的状态


二、连接数据库时报错:ora 12541 TNS 无监听程序


外地回来,登录pl/sql出现错误:ORA-12541:TNS:无监听程序。

1.       检查oracle\product\10.1.0\db_1\NETWORK\log\listener.log

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

 

Copyright (c) 1991, 2004, Oracle.  All rights reserved.

 

系统参数文件为D:\oracle\product\10.1.0\db_1\network\admin\listener.ora

写入D:\oracle\product\10.1.0\db_1\network\log\listener.log的日志信息

写入D:\oracle\product\10.1.0\db_1\network\trace\listener.trc的跟踪信息

跟踪级别当前为0

 

 pid=7180 开始

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

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=\\.\pipe\EXTPROCipc)))

2.       Oraclelistener已经启动。

3.       查看oracle\product\10.1.0\db_1\NETWORK\ADMIN\listener.ora

# listener.ora Network Configuration File: D:\oracle\product\10.1.0\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\10.1.0\db_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))

      )

    )

  )

 

(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。

4.       查看oracle\product\10.1.0\db_1\NETWORK\ADMIN\tnsnames.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)

    )

  )

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

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

5.       关闭后再启动listener

运行->cmd启动dos窗口,执行lsnrctl stop关闭,lsnrctl start启动。


ora 12541 tns 无监听程序 ORA 12541 TNS 


三、导出整个oracle数据库

办公室移了,现在要把服务器(A)上的数据库导到另一个服务器(B)上,操作如下:

在B机的orcale的E:\oracle\product\10.2.0\db_1\BIN  目录里找到exp.exe 双击,出现如图1:

ORACLE的一些错误与配置收集【ora

                                                图1

1、输入用户名和密码(你要导出的数据库对应的用户)。注:用户名是在PLSQL登陆后在窗体右上角的全名。按enter

2、输入数组提取缓冲区大小:65536 按enter

3、输入导出文件的路径 ,如:e:\testenv20120502.cmp  按enter

4、选择导出的类型,可以根据自己的需要,我是导出全部表:(1)E(完整的数据库),(2)U(用户) 或 (3)T(表): (2)U》输入E  按enter

5、接下来的导出权限、表数据、压缩区都 直接  按enter

完成以上操作,便开始导出了,效果如图2:

等执行完成,去刚输入的路径中查看,导出的xxx.dmp是否已存在,导入后续…………
