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…………

What are stored procedures in MySQL?What are stored procedures in MySQL?May 01, 2025 am 12:27 AM

Stored procedures are precompiled SQL statements in MySQL for improving performance and simplifying complex operations. 1. Improve performance: After the first compilation, subsequent calls do not need to be recompiled. 2. Improve security: Restrict data table access through permission control. 3. Simplify complex operations: combine multiple SQL statements to simplify application layer logic.

How does query caching work in MySQL?How does query caching work in MySQL?May 01, 2025 am 12:26 AM

The working principle of MySQL query cache is to store the results of SELECT query, and when the same query is executed again, the cached results are directly returned. 1) Query cache improves database reading performance and finds cached results through hash values. 2) Simple configuration, set query_cache_type and query_cache_size in MySQL configuration file. 3) Use the SQL_NO_CACHE keyword to disable the cache of specific queries. 4) In high-frequency update environments, query cache may cause performance bottlenecks and needs to be optimized for use through monitoring and adjustment of parameters.

What are the advantages of using MySQL over other relational databases?What are the advantages of using MySQL over other relational databases?May 01, 2025 am 12:18 AM

The reasons why MySQL is widely used in various projects include: 1. High performance and scalability, supporting multiple storage engines; 2. Easy to use and maintain, simple configuration and rich tools; 3. Rich ecosystem, attracting a large number of community and third-party tool support; 4. Cross-platform support, suitable for multiple operating systems.

How do you handle database upgrades in MySQL?How do you handle database upgrades in MySQL?Apr 30, 2025 am 12:28 AM

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

What are the different backup strategies you can use for MySQL?What are the different backup strategies you can use for MySQL?Apr 30, 2025 am 12:28 AM

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

How do you optimize database schema design for performance in MySQL?How do you optimize database schema design for performance in MySQL?Apr 30, 2025 am 12:27 AM

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.
