3. Oracle 甲骨文系统有限公司在北京时间 9 月 23 日发布了一款 Oracle 数据库机即 Oracle Database
Appliance。Oracle Database Appliance 是一款面向中小型企业的使用简单、用得起的高可用数据库专用服务
器,该数据库机基于 Sun Fire 服务器、Oracle Enterprise Linux 和 Oracle Database Server 11g release 2
Enterprise Edition,构成一套双节点的 Oracle Real Application Cluster 集群以供使用。

4. Oracle Unbreakable Database Appliance 的硬件采用 4-RU 的机架。包括以下这些硬件配置:
• 共享磁盘
• 24 SAS dual ported disk slots
• 20 x 600GB
• 12TB RAW, 4 TB usable
• 4 x 73GB SSD (Flash Disks) for redo logs
• 2 服务器 Host
• 2 Socket x86 per server
• 6 Cores per Socket, 12 cores per server
• 96 GB of Memory per server
• 2-12 cores per server enabled on demand
• 网络硬件
• Redundant 1Gb internal private network
• 2x 10Gb public network per server
• 6x 1Gb public network per server
• 硬件冗余
• Redundant power and cooling
• Hot-serviceable components
• Triple-mirrored storage
显然在即将举行的 Oracle Open World 2011 大会上 Oracle Database Appliance 将会成为热议的焦点。这里我们
来细数一下 Oracle Database Appliance 这款数据库机产品的优势和弱点。
6. 4.一套可扩展的平台 – 灵活的 CPU 许可证(CPU Licensing)
Oracle Database Appliance 提供了在 x86 平台上首创的灵活 CPU License 许可证采购方式。通过 Oracle
Database Appliance,客户可以只购买当前需要的 CPU 数量的 LICENSE;当系统有扩容需求时,客户可以购买
额外的 CPU 使用许可证以便在现有系统上启用更多的 CPU 内核,最大可以扩展到 24 cores。所有的 Database
Appliance 采用 Intel Xeon X5675 作为主机 CPU。
出厂的 Oracle Database Appliance 最低启用 4 cores ,最多启用满配的 24 cores。
当需要为系统扩容启用更多的 CPU 时只需要:
• 登录 My Oracle Support
• 向 Oracle Support 说明当前服务器的配置
• 下载相关的 License Key 以便重新配置服务器
• 通过命令行重新配置 Database Applianced 的 BIOS 并重启系统
5.一套管理简单的平台
Oracle Database Appliance 附带的 Appliance Manager 可以显著地简化 appliance 整个的安装流程。据某些用户
介绍整个安装过程将不超过 2 个小时,很少需要人工参与,仅仅需要为 SCAN Listener 监听器分配必要的 IP 和
DNS 域名解析服务,安装完成后用户即获得一套完善的 2 节点 RAC 集群系统,以及空的可立即投入使用的数据
库 DB。
Oracle 官方宣传的 Database Appliance 安装概念:
