Java HandlerSocket Error 121
最近在测试 nosql,安装了HandlerSocket之后,创建表 主键为 自增id,结果在 insert 的时候 指定的ID,发生了冲突....报121 错误,goo
最近在测试 nosql,安装了HandlerSocket之后,创建表 主键为 自增id,结果在 insert 的时候 指定的ID,发生了冲突....报121 错误,google之后mysql 的121 是表创建 异常...
这点做的有些不好,应该直接将mysql端的异常直接抛出来,方便用户定位问题.
另外mysql重启不使用my.cnf, 更改mysql的my.cnf后因为服务器数量太大,选择了覆盖...结果服务器起来之后最大连接只有100个....
原来是覆盖的时候 my.cnf 的其他用户 给了 W权限,导致mysql 没有使用my.cnf 启动...
升级数据库 4.0 到5.0,有一台服务器出现问题,启动的时候 竟然起了10多个进程...
原因是编译的时候使用了
--with-client-ldflags=-all-static \
--with-mysqld-ldflags=-all-static \
这个还需要在不同版本的NPTL上进行测试

MySQL's Role: Databases in Web Applications
Apr 17, 2025 am 12:23 AM
The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.
Explain the role of InnoDB redo logs and undo logs.
Apr 15, 2025 am 12:16 AM
InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.
MySQL: An Introduction to the World's Most Popular Database
Apr 12, 2025 am 12:18 AM
MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.
MySQL's Place: Databases and Programming
Apr 13, 2025 am 12:18 AM
MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen
Why Use MySQL? Benefits and Advantages

MySQL: From Small Businesses to Large Enterprises
Apr 13, 2025 am 12:17 AM
MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.
How does MySQL index cardinality affect query performance?
Apr 14, 2025 am 12:18 AM
MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
