AIX6安装Oracle 10G RAC遇到的问题总结
# mv /usr/sbin/fuser /usr/sbin/fuser.old# touch /usr/sbin/fuser然后在弹出的窗口中点ldquo;Retryrdquo;按钮,就可以完成rd
1、安装crs的最后一步运行root.sh脚本之前需要修改$CRS_HOME/bin/racgvip脚本,否则会导致vip无法启动,修改方法如下:
# cd $CRS_HOME/bin
# cp racgvip racgvip.old
# vi racgvip
将221,231,,371这三行中的 $5 修改为 $6
2、第二个点执行root.sh时 报Oracle cluster verification utility 起用VIPCA最后报crs-0223 手工查看crs_stat的状态,发现有一个资源没有起来,尝试手工启动 并正常 对oracle cluster verification utility 的错误 在弹出的窗口中点“Retry”按钮后正常
3、升级crs到10.2.0.4,运行root02.sh之后,vip又变得无法启动,这时需要再次修改$CRS_HOME/bin/racgvip,方法如下:
注意是在运行root02.sh之后再修改
# cd $CRS_HOME/bin
# cp racgvip racgvip.10204.old
# vi racgvip
将263,275这两行中的 $5 修改为 $6
4、升级rdbms到10.2.0.4过程中,会弹出一个窗口报告java进程在运行,不允许升级,这又是一个bug,修改方法如下:
# mv /usr/sbin/fuser /usr/sbin/fuser.old
# touch /usr/sbin/fuser
然后在弹出的窗口中点“Retry”按钮,就可以完成rdbms的升级
5、由于第四步时删除了fuser命令导致在重起主机并起HA时报错, 把fuser.old还原回去 还是报错,后发现是相关的权限不对 加上权限后OK

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

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.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.
