ORA-12514 TNS 监听程序当前无法识别连接描述符中请求服务
太久没查看我的ORACLE了,怕自己密码忘了,刚打算准备用青蛙(TOAD)查看一下我的ORACLE,打开连接就报错:ldquo;ORA-12514 TNS 监
太久没查看我的Oracle了,怕自己密码忘了,刚打算准备用青蛙(TOAD)查看一下我的ORACLE,,打开连接就报错:“ORA-12514 TNS 监听程序当前无法识别连接描述符中请求服务”。
我是用的WIN7,建的虚拟机,在虚拟机上进行编程学习,ORACLE也是一样,安装在虚拟机上的。为什么出现这个原因,不清楚。
在网上搜了一下,照网上说的方法,问题已经解决。
更改listener.ora文件,用记事本可以打开。
目录:C:\oracle\product\10.2.0\db_1\NETWORK\ADMIN
# listener.ora Network Configuration File: C:\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 = C:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
)
(SID_DESC =
(GLOBAL_DBNAME = DEMO)
(ORACLE_HOME = C:\oracle\product\10.2.0\db_1)
(SID_NAME = demo)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.21.128)(PORT = 1521))
)
)
红色为需要添加的部分
然后重新配置对该实例的监听
本地NET服务名配置 --> 重新配置 --> 选择需要重新配置的实例名(DEMO,不记得,可以查看同目录下的tnsnames.ora) --> 写入tnsnames.ora中的记录进行地址及端口
其实弄到这里,网上提示是进行服务器重启,我没重启,但我把所有ORACLE开头的服务全都重启了一遍,现在可以用青蛙进行操作了。

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
