通过SSH工具或是XShell工具进入远程Linux下。
其中,通过SSH工具登录的界面如下:
其中Host Name是远程服务器的ip地址。User Name是服务器的一个用户名,端口号默认22,Connect进去后可以填写服务器的密码。
通过XShell工具登录的界面如下:
点击上面的New按钮,填写HOST主机地址,即服务器的IP地址,点击OK即可。
输入命令: cd / 到根目录下

Linux下创建Oracle用户和表空间,赋予权限等操作
通过sqlplus远程连接Oracle,其表示:sqlplus 用户名/密码@远程Oracle服务器地址:Oracle端口号/Oracle的service_name
sqlplus sys/nmc601@10.28.17.129:1521/nmcdb.nmc.gov.cn as sysdba;
如果存在TS_MISPS表空间,则删除此表空间和其附带的文件
drop tablespace TS_MISPS including contentsand datafiles cascade constraints;
查看连接着的用
select username,sid,serial# from v$session;
//级联删除用户
drop user MISPS cascade;
//创建表空间,文件放在Oracle安装目录内部的oradata目录下
create tablespace TS_MISPS datafile '/home/oracle/app/oracle/oradata/TS_MISPS.dbf'size 300m;
//让表空间自动变化
alter database datafile '/home/oracle/app/oracle/oradata/TS_MISPS.dbf'autoextend on next 10m;
create user MISPS identified by ‘MISPS;
//让用户使用这个表空间
alter user MISPS default tablespaceTS_MISPS;
//分配session的权限
grant create session to MISPS;
//分配创建表的权限
grant create table to MISPS;
//分配创建视图的权限
grant create view to MISPS;
//分配创建触发器的权限
grant create trigger to MISPS;
//这行必须有
grant unlimited tablespace to MISPS;
//分配创建索引的权限
grant create any index to MISPS;
//分配修改表的权限
grant alter any table to misps;
//分配修改存储过程的权限
grant alter any procedure to MISPS;
//分配删除表的权限
grant drop any table to MISPS;
//赋予删除视图的权限
grant drop any view to MISPS;
//赋予删除索引的权限
grant drop any INDEX to MISPS;
//赋予删除存储过程的权限
grant drop any procedure to MISPS;
//赋予查询,插入,更新,,删除表的权限
grant select any table,insert anytable,update any table,delete any table to MISPS;
//让表unlock,没有这句会出现ORA-28000: the account is locked错误
alter user MISPS account unlock;
//必须赋予connect,resource权限
grant connect,resource,DBA to MISPS;
//这一句是修改密码的sql
alter user MISPS identified by MISPS;

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
