Windows下手动完全卸载Oracle使用,Oracle自带的Universal Installer卸载存在两个问题:速度慢;不干净;不完全;还有一些注册表
使用Oracle自带的Universal Installer卸载存在两个问题:
1) 速度慢;
2) 不干净;不完全;还有一些注册表残留,会影响到后来的安装。
所以,推荐使用手工卸载Oracle。
1.【win+R】->【services.msc】,关闭oracle所有的服务。
2. 打开注册表【win+R】->【regedit】。打开路径: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ 删除该路径下的所有以oracle开始的服务名称,这个键 是标识Oracle在windows下注册的各种服务!
3.打开注册表,找到路径: HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE 删除该oracle目录,该目录下注册着Oracle数据库的软件安装信息。
4.删除注册的oracle事件日志,打开注册表 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application 删除注册表的以oracle开头的所有项目。
5.删除环境变量path中关于oracle的内容。 鼠标右键右单击“我的电脑-->属性-->高级-->环境变量-->PATH 变量。 删除Oracle在该值中的内容。注意:path中记录着一堆操作系统 的目录,在windows中各个目录之间使用分号(;)隔开的,删除时注意。 建议:删除PATH环境变量中关于Oracle的值时,将该值全部拷贝到文本编辑器中,找到对应的 Oracle的值,删除后,,再拷贝修改的串,粘贴到PATH环境变量中,这样相对而言比较安全。
6.重新启动操作系统。
7.重启操作系统后各种Oracle相关的进程都不会加载了。这时删除Oracle_Home下的所有数据。(Oracle_Home指Oracle程序的安装目录)
8.删除C:\Program Files下oracle目录。 (该目录视Oracle安装所在路径而定)
9.删除开始菜单下oracle项,如: C:\Documents and Settings\All Users\「开始」菜单\程序\Oracle - Ora10g 不同的安装这个目录稍有不同。 如果不删除开始菜单下的Oracle相 关菜单目录,没关系,这个不影响再次安装Oracle.当再次安装Oracle时,该菜单会被替换。
至此,Windows平台下Oracle就彻底完全卸载了。

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
