概述
在真正的海量数据库环境中，DBA可能会花费很多的时间来作磁盘管理，比如一个表空间将占满整个磁盘，DBA就需要再添加一块磁盘到操作系统中，然后再在新的磁盘上创建新的数据文件，如果是单个磁盘这倒不是很繁琐，问题是如果原先我们使用的是RAID或者说是LVM，那么现在大量的数据仍然是分布在以前的那些磁盘上，如果我们想让这些数据均匀地分布在以前的磁盘和新增加的磁盘上，我们可能就要耗费一天甚至几天的时间来作原先数据的导出导入。那么如果有一种方法，能实现我们就把一块磁盘加到系统里，然后告诉Oracle我们要用这块盘了，剩下的工作全部由Oracle来完成，该是多好的一件事情！幸运的是，Oracle
本文通过vmware安装RHEL3 + Oracle
硬件配置
IBM R50 5GC
迅驰
软件配置
WindowsXP Pro SP1，VMware GSX Server
安装VMware
这一步就不多说了，我安装的是VMware GSX Server，没有测试过VMware Workstation，所以不保证可以实现本文中的步骤。
在VMware中安装RHEL3
1． 安装RHEL3
这个过程也不多说了，跟实际环境中安装RHEL3一样。值得注意的是，由于通过Vmware所以可能在安装时无法正常启动Xwindow，那么在字符界面下安装就可以了。安装完毕重新启动系统，Xwindow会自动启动的。记住安装所有的开发包即可，这将会尽量避免以后可能出现的link错误。我的测试环境中给了RHEL3总共
2． 添加4块虚拟磁盘
按照如下操作，在虚拟机的属性中选择添加硬件，然后添加一个Virtual Disk
下一步，由于我们创建的虚拟磁盘只是用来放置Oracle的数据文件，而且我们将使用ASM中的failgroup的条带功能，所以设置最大size是
下一步，指定虚拟磁盘文件的名称和存放位置，默认存放在虚拟机的相同目录下。这里我们指定文件名为physical1
点击Advanced按钮，设置虚拟磁盘的物理挂载点，通常我们选择和虚拟机已有的系统盘在不同的SCSI端口上，比如我们虚拟机的系统盘是SCSI0:0，那么就设置这个磁盘为SCSI1:0。即将添加的另外三块磁盘依次为SCSI1:1、SCSI1:2和SCSI1:3

How does Go language implement the addition, deletion, modification and query operations of the database?
Mar 27, 2024 pm 09:39 PM
Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.
How does Hibernate implement polymorphic mapping?
Apr 17, 2024 pm 12:09 PM
Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.
An in-depth analysis of how HTML reads the database
Apr 09, 2024 pm 12:36 PM
HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.
iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos
Jul 18, 2024 am 05:48 AM
Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

Tips and practices for handling Chinese garbled characters in databases with PHP
Mar 27, 2024 pm 05:21 PM
PHP is a back-end programming language widely used in website development. It has powerful database operation functions and is often used to interact with databases such as MySQL. However, due to the complexity of Chinese character encoding, problems often arise when dealing with Chinese garbled characters in the database. This article will introduce the skills and practices of PHP in handling Chinese garbled characters in databases, including common causes of garbled characters, solutions and specific code examples. Common reasons for garbled characters are incorrect database character set settings: the correct character set needs to be selected when creating the database, such as utf8 or u
