Oracle Database 12c发布也有一周了，这几天尝试了下单机、RESTART和RAC的安装，其中发生了不少趣事。比如安装Oracle 12c Restart花费了4小时多最终笔记本死机、RAC安装过程中采用HAIP特性却失败等等。
Oracle 12c RAC引入了Flex Cluster的概念，但我尚未研究成功。
下面是传统方式安装Oracle 12c RAC的教程。
Oracle 单实例 从32位 迁移到 64位 方法
在CentOS 6.4下安装Oracle 11gR2(x64)

网络配置信息：
备注：从下面信息中可以发现，每个节点服务器我都添加了五个网卡，eth0用于PUBLIC，而eth1~eth4用于Private，本想采用HAIP特性。
但我在安装实验过程中HAIP特性上发生了节点2无法启动ASM实例的问题，因此最后只用了其中eth1接口。
至于HAIP导致的问题，可能是出于BUG，这个问题还有待仔细troubleshooting。

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.
What are the different types of indexes in MySQL?Apr 25, 2025 am 12:12 AMThere are four main index types in MySQL: B-Tree index, hash index, full-text index and spatial index. 1.B-Tree index is suitable for range query, sorting and grouping, and is suitable for creation on the name column of the employees table. 2. Hash index is suitable for equivalent queries and is suitable for creation on the id column of the hash_table table of the MEMORY storage engine. 3. Full text index is used for text search, suitable for creation on the content column of the articles table. 4. Spatial index is used for geospatial query, suitable for creation on geom columns of locations table.

How does MySQL differ from SQLite?Apr 24, 2025 am 12:12 AMThe main difference between MySQL and SQLite is the design concept and usage scenarios: 1. MySQL is suitable for large applications and enterprise-level solutions, supporting high performance and high concurrency; 2. SQLite is suitable for mobile applications and desktop software, lightweight and easy to embed.
What are indexes in MySQL, and how do they improve performance?Apr 24, 2025 am 12:09 AMIndexes in MySQL are an ordered structure of one or more columns in a database table, used to speed up data retrieval. 1) Indexes improve query speed by reducing the amount of scanned data. 2) B-Tree index uses a balanced tree structure, which is suitable for range query and sorting. 3) Use CREATEINDEX statements to create indexes, such as CREATEINDEXidx_customer_idONorders(customer_id). 4) Composite indexes can optimize multi-column queries, such as CREATEINDEXidx_customer_orderONorders(customer_id,order_date). 5) Use EXPLAIN to analyze query plans and avoid
Explain how to use transactions in MySQL to ensure data consistency.Apr 24, 2025 am 12:09 AMUsing transactions in MySQL ensures data consistency. 1) Start the transaction through STARTTRANSACTION, and then execute SQL operations and submit it with COMMIT or ROLLBACK. 2) Use SAVEPOINT to set a save point to allow partial rollback. 3) Performance optimization suggestions include shortening transaction time, avoiding large-scale queries and using isolation levels reasonably.
