客户需求:
随着基于intel处理器的服务器性能及可靠性的不断提升,将原有的工作于UNIX服务器上的数据库服务移植到基于Intel处理器的服务器上成为了现今企业公司提高IT投资回报率的重要的选择。众所周知,数据库系统是企业IT系统的核心部分,不仅需要数据库服务器具有极强的处理能力,也要求数据库服务器系统具有很高的可靠性,以保证应用系统能够随时访问到数据库中的数据。上海能新网络系统有限公司针对这种情况,提出了特别设计的数据库解决方案。
方案功能与优势:
全冗余,高可用的数据库方案:
该方案采用全冗余设计,无论在服务器,光纤交换机,光纤控制器均采用冗余配置,以保证系统的整体可靠性,避免单点故障的发生。服务器选择x366或x460服务器,因为这两款服务器均采用第三代企业级x架构技术作为设计基础,在TPMC性能测试中这两款服务器都取得了同级别最好的成绩,x366服务器可配置4颗Intel EM64T处理器,而x460的处理器可以扩展到32颗。
方案优势:
1.x366和x460服务器采用第三代企业级x架构技术,在处理性能上得到了极大提高;2.采用性价比高的DS400光纤存储设备,能够搭建入门级的SAN;3.采用全冗余设计,能有效避免单一设备的单点故障,提高系统的可用性;4.利用了数据库的并行处理功能,服务器数量可以按照需要进行扩展。

建议配置方案:
类别 | 产品号 | 产品描述 | 数量 |
硬件 | 8863或8872 | X366或x460 | 2(每台服务器配置两块硬盘,做成RAID-1) |
1700 | DS400光纤存储 | 1(存储容量最大可以扩展到12TB,支持RAID0,1,10,5,50的阵列方式) | |
24P0960 | 2GB HBA卡 | 4(每台服务器两块) | |
2006L10 | Storage Switch Model L10 | 2 | |
22R0483 | 短波光纤模块(L10用) | 8 | |
19K1271 | 短波光纤模块(DS400用) | 4 | |
操作系统 | Windows 2003 Enterprise Server或Redhat Linux EL3 | 2 | |
软件 | IBM DB2, Oracle 10G RAC, SQL server | 1 |
数据库服务器的处理能力可以根据业界基准测试指标TPCC来进行评估。TPCC是用来评估服务器对于数据库联机应用的响应速度,数值越高,表明该服务器性能越强。
X366(4颗CPU)的TPCC值为141504 tpmC,X460(8颗CPU)的TPCC值为250975tpmC。

Analysis of Java framework security vulnerabilities shows that XSS, SQL injection and SSRF are common vulnerabilities. Solutions include: using security framework versions, input validation, output encoding, preventing SQL injection, using CSRF protection, disabling unnecessary features, setting security headers. In actual cases, the ApacheStruts2OGNL injection vulnerability can be solved by updating the framework version and using the OGNL expression checking tool.

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
