白金服务:补丁升级服务

Oracle为符合认证的白金配置提供一年四次免费的远程补丁升级服务. 客户需要:
   (1)Oracle联系进行远程补丁安装的规划,
   (2)
同意所要安装的补丁. 补丁安装所需的时间需在安装前协商好并记录在门户网站上. 可以通过下面的链接查看到认证的白金配置, 被升级的程序以及远程补丁安装的范围:           www.oracle.com/us/support/library/remote-quarterly-patching-scope-1652890.pdf


除了Oracle数据库11.2.0.4,为了确保是认证的白金配置,客户必须在6个月内升级至白金认证配置的最新补丁包版本,并且不允许比最新补丁包版本落后2个版本,可参看 http://www.oracle.com/us/support/library/certified-platinum-configs-1652888.pdf; 针对Oracle数据库11.2.0.4客户必须在12个月内升级至白金认证配置的最新补丁包版本,并且不允许比最新补丁包版本落后4个版本。http://www.oracle.com/us/support/library/certified-platinum-configs-1652888.pdf


除以下部分陈述的安装服务,客户需自行安装补丁将系统升级至认证的白金配置:


1)远程补丁安装不包括Oracle数据库版本升级(如:11.x12.x)。
2)远程补丁安装服务不适应于运行SAP应用的Oracle 数据库。
3)原则上远程补丁安装不包含Oracle数据库补丁集的版本升级(如:11.2.0.211.2.0.3),但是,如果客户要求,并且Oracle也同意提供此项服务,那么Oracle数据库补丁集的版本升级服务(如:11.2.0.211.2.0.3)将被视为一次独立的远程补丁安装,会占用Oracle每年为客户提供的免费远程服务的次数。

 


远程补丁安装包括以下服务:


(1) 支持行为讨论---每季度一次,Oracle会通过电话与客户的技术联系人之一讨论每季度所有的认证白金补丁安装行为,包括客户技术人员登记的服务请求,状态报告,未完成的行为;并为您的升级方案提供一份评估。



a. Oracle会在客户的认证白金配置处于在线状态时进行远程补丁安装。补丁会被安装在每个应用,服务器,存储服务器或是存储阵列上。补丁将会以滚动方式每次在一个服务器上进行安装。


b. Oracle会在客户的认证白金配置处于在线状态时进行远程补丁安装。为了完成补丁安装,认证白金配置可能需要关闭,硬件系统可能需要重启并且认证白金配置需要进行备份。


(2) 远程补丁安装---根据补丁,Oracle将通过以下方式之一或是相结合进行补丁安装

 


在规划远程补丁安装时,各方需讨论确定Oracle进行远程补丁安装的方式和远程补丁安装的时对认证白金配置的预期影响。


以下文档详细介绍了执行 Oracle 白金服务远程补丁安装期间可能需要完成的一些活动http://www.oracle.com/us/support/library/platinum-remote-patch-checklist-1958298.pdf

Exalogic硬件架构介绍

Oracle Exalogic Elastic Cloud是全球首个专门设计的中间件云服务器集成系统。Exalogic旨在为企业提供一个安全、关键任务的私有云基础平台,用以支持几乎无限大的规模、无与伦比的性能和超乎想象的管理简便性。虽然Exalogic 是针对企业Java、Oracle 融合中间件和Oracle融合管理软件的优化产品,但它也是运行当今广泛部署的成千上万第三方和定制Linux 及Solaris 应用的优秀环境。Exalogic 是由硬件和软件组件构成的一个集成系统平台,每个组件都是Oracle 产品组合中的战略技术。那么,Exalogic到底是什么样的呢?今天我们就来看一下Exalogic的硬件架构。

Exalogic硬件是预先装配好的集成系统,并按标准的19英寸42U机架配置交付。每个Exalogic 配置都是一个支持计算密集型工作负载均衡的中间件云服务器容量单元。每个Exalogic 配置都包含多个热插拔计算节点、一个集群式高性能磁盘存储子系统和一个高带宽互连架构,该架构包含了连接配置内各个组件以及外部其他Exalogic 或Exadata 数据库机机架所需的交换机。此外,每个配置还包含多个用于与数据中心服务网络集成的10 Gb 以太网端口和用于与数据中心管理网络集成的千兆位以太网端口。所有Exalogic 配置在各个层次都是完全冗余的,并且其设计消除了单点故障。

Exalogic根据部件配置的多少可分为八分之一配、四分之一配、半配和满配等。下图是一个Exalogic满配(full rack)的全景图。

exalogic full rack

Exalogic的硬件架构主要由以下几部分组成:

  • X86计算节点
  • ZFS存储节点
  • Infiniband交换机
  • Cisco管理网交换机
  • 电源

下图就以满配为例简单的表示了一下Exalogic的基本组成部分。

Exalogic基本组成

有了以上的简要介绍,相信您已经对Exalogic的硬件架构有了一些初步了解了。下面我们较为详细的介绍下Exalogic的几个主要组成部件。


X86计算节点

每个 Exalogic 计算节点都是一个配有多核x86 Xeon 处理器或SPARC-T3 处理器、冗余电源、快速ECC DIMM 内存和冗余InfiniBand 主机通道适配器的完全独立的计算容量单元。因此,每个计算节点都可以理解成一个独立的物理服务器。下图是一组计算节点的近景图。

an exalogic compute node

每个计算节点还包含两个固态硬盘 (SSD),它们托管着用于引导节点的操作系统映像,并作为系统在故障管理过程中所生成诊断数据的高性能本地交换空间和存储。

因为多计算节点的存在,在Exalogic上配置高可用性应用变得非常容易。您可以配置应用群集以横跨两个或多个计算节点,在一个节点上出现问题或者需要进行维护时,其他节点仍可为最终用户提供应用服务。


ZFS存储节点

每个Exalogic主机都包含有ZFS存储节点,以供存储用户的应用程序、数据、应用日志以及其它任何对用户有用的数据。每个计算节点都可以很容易的挂载存储节点中的一个分区以支持节点上应用的运行。下图是存储节点的近景图,用红框标明的部分即为存储节点。

an exalogic storage head

Exalogic的存储节点包含两个物理上完全独立的存储机头。每个存储机头都是使用InfiniBand与Exalogic的其他组件相连,并使用完全冗余的active/standby配置以实现存储的高可用性。


Infiniband交换机

Infiniband交换机是Exalogic的一个重要组成部分。Exalogic的所有部件都是通过Infiniband来连接的。Exalogic使用基于四倍速率的InfiniBand构建起Exabus I/O通讯接口以连接Exalogic系统中的所有硬件和软件。如下图所示,所有的部件都是通过Exabus连接起来并实现通讯的。

infiniband switches

InfiniBand对中间件云服务器系统很重要。除了在部署的所有硬件设备之间提供极快的高吞吐量互连外,它还提供极大的规模、极高的应用隔离度和灵活性。

Exalogic系统所用的无损切换的InfiniBand I/O 架构将所有系统连接成了一台大型计算机。可以从八分之一机架(Eighth Rack)开始,然后扩展到四分之一机架(Quarter Rack)或者半机架(Half Rack),再到一个大型全机架(Full Rack),此外,还可以将多达八个全机架的Exalogic 硬件(或Exalogic 和Exadata 配置的任何组合)连接在一起构成组合机架(Multi-Rack),且无需任何外部交换机。如需八个以上的Exalogic 或Exadata 硬件机架,Oracle 允许使用若干个高容量数据中心交换机来创建包含数百个机架和数万个处理器的Exalogic 云。

下图以Exalogic的最新版本X5-2为例,展示了Exalogic的扩展过程以及每一阶段的配置参数。

extended exalogic racks

Exalogic系统的横向扩展意味着增大云规模的同时系统性能不会下降。同样重要的是,Exalogic 云是可以动态细分为安全容量单元的资源池。这种能力植根于InfiniBand 自身的设计中,而这也正是InfiniBand的设计初衷。


Cisco管理网交换机

每个Exalogic主机都包含了一个管理网交换机。有了这个交换机,Exalogic的各个主要部件就可以通过它来连接到客户的管理网了。下图是一个交换机的背面图。

exalogic back rear

这个管理网交换机可以说是Exalogic对客户数据中心管理网的安全接口。有了这个交换机,客户对Exalogic的管理可以和服务网络完全独立开来,可以在完全不影响应用访问的情况下对设备进行管理。这种设计对于服务器的维护是非常方便的。


小结

讲到这里,相信您已经对Exalogic的硬件架构有一定了解了吧。欢迎访问Exalogic中间件服务器中文网站获得更多关于产品与解决方案的资讯。

News from the Modular JavaFX Application Framework

The biggest problem at that time was that the mouse didn't work on the menus. I ran the project again today and I guess my JDK is different (newer) than what I was using at that time because now that problem is fixed, without any changes in my code, i.e., something has been enhanced on the (more...)

My first experiences with ThreadLogic by Marcel van de Glind

clip_image002A while ago I came into touch with ThreadLogic. Most of the people whom I was talking about it, did not know the tool. This unfamiliarity with ThreadLogic made me decide to write this blog. I think that every WebLogic Administrator should know ThreadLogic and that it is also a very interesting tool for Fusion Middleware Developers.

But let me start at the beginning. A while ago Michael Sahadat, a SOA/Integration Architect at Oracle, came (more...)
