在本文中，介绍了rac环境下配置ogg的单向同步；在配置过程中，2节点的rac数据库做为source端，单实例的数据库作为target端，香港服务器，下面是具体的环境介绍!
source端：
操作系统版本：rhel5.4 64bit
数据库版本：11.2.0.3 64bit
ogg版本：fbo_ggs_Linux_x64_ora10g_64bit.tar
rac数据库名：rac.yang.com
public ip:192.168.1.41/24,192.168.1.42/24
private ip:192.168.122.41/24,192.168.122.42/24
vip:192.168.1.141/24,192.168.1.142/24
scan名：rac-scan.yang.com
scan-ip:192.168.1.144/24,192.168.1.145/24,192.168.1.146/24

target端：
操作系统版本：rhel5.4 64bit
数据库版本：11.2.0.3 64bit
ogg版本：fbo_ggs_Linux_x64_ora10g_64bit.tar
数据库名：dg3.yang.com
ip:192.168.1.63/24

一：首先在两个rac节点上配置ASM动态注册,11g的监听器引入了endpoints_listener.ora文件管理

二：acfs上安装ogg，acfs用来存放ogg的安装目录，便于集群件的共享，在10g上部署可以选择ocfs2，acfs的部署过程参考：

三：rac数据库上进行配置，创建用户，授权，运行执行序列号和ddl复制的相关脚本等

四：在source端配置extract group

五：在source端配置data pump extract group

六：target端配置，这里要保证在tnsnames.ora文件中配置了dg3连接串，同时建立/vol2/ogg/dirdat/rt目录，并授权；在这里未测试过target端和source使用不同的目录是否可行！

七：启动各进程

进程安排在最后启动，美国空间，在启动source端的pump进程之前，如果target端的replicat进程未启动，则会报如下错误：
2012-07-15 13:56:14 ERROR OGG-01033 There is a problem in network communication, a remote file problem, encryption keys for target and source do not match (if using ENCRYPT) or an unknown error. (Remote file used is /vol2/ogg/dirdat/rt000000, reply received is Could not create /vol2/ogg/dirdat/rt000000).

八：测试同步情况

总结：rac环境下配置ogg，香港服务器，基本同单实例无异！重点需要注意的地方有以下几点!
1：使用ASM存储，需要先配置ASM实例的静态注册，同时在tnsnames.ora文件中配置连接串
2：在配置exttract进程中，注意需要配置TRANLOGOPTIONS 参数，输入连接asm实例的凭证
3：在配置exttract进程中，添加tranlog的时候，需要写thread 2
4: 注意进程的启动顺序，先是source和target端的mgr进程，其次是source端的extract进程，target端的replicat进程，最后是source端的extract pump进程

本文不包含source端的failover功能，后续将继续测试,敬请关注！

Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

MySQL vs. Other Programming Languages: A ComparisonApr 19, 2025 am 12:22 AM

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

Learning MySQL: A Step-by-Step Guide for New UsersApr 19, 2025 am 12:19 AM

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL: Essential Skills for Beginners to MasterApr 18, 2025 am 12:24 AM

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL: Structured Data and Relational DatabasesApr 18, 2025 am 12:22 AM

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL: Key Features and Capabilities ExplainedApr 18, 2025 am 12:17 AM

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3.
