Oracle ACL(Access Control List)
在oralce 11g中假如你想获取server的ip或者hostname,执行如下语句
|
1 2 3 |
|
如果在oracle 9i中能够正常执行,但在11g中你可能会得到一个莫名其妙的错误提示:
ORA-24247: network access denied by access control list(ACL)
你可能马上想到是需要啥额外的权限,而我们平时赋予权限一般是grant XXX to user_name;但你找不到有啥跟ACL对应的权限.
实际上这里确实需要额外权限,但赋予权限的方式相当变态,跟grant的方式太不一样了.
细粒度访问网络服务
为了更细致的控制网络权限,Oracle 11g中针对这么几个PL/SQL API(UTL_TCP， UTL_SMTP， UTL_MAIL， UTL_HTTP和 UTL_INADDR)的访问设置了单独的权限访问控制方式.
其中UTL_SMTP,UTL_MAIL是跟邮件相关的,比如你可以在触发器中设定当在某些表中做插入删除操作时就发个邮件知识某个负责人.
赋予权限
假如要给用户赋予访问上面提到的那些函数咋整呢? 要通过如下的一段pl/sql语句

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |

如果要删除上面的控制列表

1 2 3 4 5 |

删除这个列表,那用些列表赋予权限的那些用户自然也被取消相应的权限了.
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.

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),
