客户反映说他们的系统不能上传附件了，上传附件的时候就报ORA-600错误，具体错误如下:ORA-00600: internal error code, arguments: [6002], [32], [0], [2], [0], [], [], [], [], [], [], [],
网上有很多针对6002的处理方法，说的原因基本都是说表上的索引有问题，MOS上也有相关说明，具体请参看MOS文章[ID 47449.1], 用户也根据这个思路进行了处理，对表上的索引进行了rebuild，后来又将索引删除，在create index，但是问题一直还是出现。
以下是我的处理过程，首先我们来看trace文件：

注意到引起ORA-600错误的为一个insert语句，对应的表为T_MX_ATTACHMENT，与用户确认后得知，这个表正式用来存放附件的表。还注意两个对象编号，按如下方式查询两个出现问题的对象类型：
What are the different storage engines available in MySQL?Apr 26, 2025 am 12:27 AMMySQLoffersvariousstorageengines,eachsuitedfordifferentusecases:1)InnoDBisidealforapplicationsneedingACIDcomplianceandhighconcurrency,supportingtransactionsandforeignkeys.2)MyISAMisbestforread-heavyworkloads,lackingtransactionsupport.3)Memoryengineis
What are some common security vulnerabilities in MySQL?Apr 26, 2025 am 12:27 AMCommon security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.
How can you identify slow queries in MySQL?Apr 26, 2025 am 12:15 AMIdentifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.
How can you monitor MySQL server health and performance?Apr 26, 2025 am 12:15 AMTo monitor the health and performance of MySQL servers, you should pay attention to system health, performance metrics and query execution. 1) Monitor system health: Use top, htop or SHOWGLOBALSTATUS commands to view CPU, memory, disk I/O and network activities. 2) Track performance indicators: monitor key indicators such as query number per second, average query time and cache hit rate. 3) Ensure query execution optimization: Enable slow query logs, record and optimize queries whose execution time exceeds the set threshold.
Compare and contrast MySQL and MariaDB.Apr 26, 2025 am 12:08 AMThe main difference between MySQL and MariaDB is performance, functionality and license: 1. MySQL is developed by Oracle, and MariaDB is its fork. 2. MariaDB may perform better in high load environments. 3.MariaDB provides more storage engines and functions. 4.MySQL adopts a dual license, and MariaDB is completely open source. The existing infrastructure, performance requirements, functional requirements and license costs should be taken into account when choosing.
How does MySQL's licensing compare to other database systems?Apr 25, 2025 am 12:26 AMMySQL uses a GPL license. 1) The GPL license allows the free use, modification and distribution of MySQL, but the modified distribution must comply with GPL. 2) Commercial licenses can avoid public modifications and are suitable for commercial applications that require confidentiality.
When would you choose InnoDB over MyISAM, and vice versa?Apr 25, 2025 am 12:22 AMThe situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.
Explain the purpose of foreign keys in MySQL.Apr 25, 2025 am 12:17 AMIn MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
