由于公司ERP系统的平台为RedHat Linux ES4+Oracle10g,暂时交由我进行维护,所以想借此机会学习一下Linux,对自己的要求不高,就是能在Linux上安装成功Oracle,然后会备份和恢复数据库.首先就在当当网上买了一本的书,由清华出版社翻译的,经过一段时间的阅读,可以说对我的学习没有任何实质性的帮助,建议初学者不要买这本书.
我首先尝试的是在红帽Linux ES4安装Oracle 10g,经过若干天的尝试,同时也下载了许多的资料一步一步的做,最后都是不成功,最主要的是在进入Oracle安装的时候,老是检查出来安装的一些RPM包版本不对,人搞得很烦燥,并且本人对Linux也是一菜鸟,因此在这之后的好长一段时间都没再去尝试了.
最后在Oracle.com.cn的论坛上看到了小布老师专门给菜鸟制作的视频讲座,才又开始新的学习.终于按照视频里的一步一步,安装成功了11g.其实我的文章就是根据视频里的步骤再复述了一遍,我的最大目的是温习一下安装的过程,让自己更熟练一些.,同时也给同级别的菜鸟一些学习的信心.
操作平台:VMWARE6.0+CentOS4.5.(可在下载).大家注意,Linux版本的不同会给菜鸟带来很多纳闷的困扰,我建议如果想按照这篇文章安装,就一定要下载这个Linux版本,它是免费的,不会像红帽一样涉及到版权的问题.可以说等于红帽的ES4版本.
数据库版本:Oracle11G R1(我是在emule上下载的)
辅助软件:SecureCRT Filezella AdobeAcrobatReader
硬件:内存 1GB 硬盘空间>18GB
我下载的是DVD版本的OS,在虚拟机软件中先将OS载入到了光驱中.
在Linux中,一定要注意大小写.特别是命令.
首先在虚拟机软件中安装CentOS,在安装时,
1 SWAP分区我设置了2048MB即内存的2倍,其它空间都装载到了"/"根目录,共计两个分区
2 配置好静态IP地址
3 选择"自定义安装",安装必需的软件包"GNOME图形界面" ,Developments Tools和Legacy Softeare Development, Editors.其它可以不必安装,节省资源.

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
