Oracle宣布释出与Emulex合作开发的资料完整(data integrity)检验开放源码,让Linux社群使用者在资料转移时,能获得更周全的保护。 目前可采用此程式码的Linux核心为2.6.27.Oracle表示,此次程式码的释出代表Oracle对高阶企业Linux系统的承诺与努力。此开放源码能确保资料转移时的完整性,不论是从应用程式到资料库,或是从Linux作业系统转移到硬碟。
新的程式码能让Linux作业系统拥有额外的检验方式,协助删除未标记的错误资料,降低错误资料被写入硬碟的可能性,同时也能减少应用程式与资料库的错误,或影响系统的上线时间。
此次释出的程式码为Oracle与Emulex所合作开发,依循既有的储存标准规范,首次让Linux的核心程式能利用这些重要的资料保护资讯。对Linux使用者而言,此程式码将能为整个软体架构,提供丰富的资料完整检验能力,,让使用者能降低成本、提升效能与上线时间。
Oracle与Emulex同时也将合作进行一些客户的先期导入方案,计划选择特定的客户群,在真实的IT环境中先行导入此程式码,并进一步测试各种新的资料完整检验功能。
储存厂商Emulex公司产品行销副总裁Scott McIntyre指出,资料完整性对任何企业而言都非常重要。Emulex与Oracle的目标是协助资料中心的管理者,能快速发现并修正错误的资料,以保护他们的企业资产。此次释出的程式码,意味着我们对Linux平台资料完整性所做的努力。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
