本文参考:http://www.360doc.com/content/12/0403/01/9623234_200390473.shtml使用RMANDUPLICATE命令可以在保留目标数据库的基础上依靠目标数据库(TargetDataba
本文参考:
使用RMANDUPLICATE命令可以在保留目标数据库的基础上依靠目标数据库(TargetDatabase)的备份创建一个副本数据库(DuplicateDatabase)。该副本即可与目标数据库完全相同,也可仅包含目标数据库表空间的一部子集。
同机复制数据库的目的:
1、测试备份和恢复的过程
2、导出数据,香港空间,香港虚拟主机,例如在生产库无操作删除一张表,通过副本数据库将其导进生产库
实验环境:
目标数据库:linux 平台上的oracle 10g (orcl)
副本数据库:linux平台上的oracle 10g (lck)
同机复制数据库的过程:
1、创建副本数据库的参数文件和密码文件
参数文件
3、将副本数据库启动到nomount
4、对目标数据库进行全库备份
注意此处,香港服务器,备份完成之后,需要切换日志,否则,执行duplicate会报以下错误
5、配置监听,将副本数据库静态注册到监听器
6、配置字符串
7、复制数据库
rman target / auxiliary sys/oracle@lck
ok,复制完成!

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

The article discusses using MySQL's ALTER TABLE statement to modify tables, including adding/dropping columns, renaming tables/columns, and changing column data types.

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.
