WebSphere Application Server Customer,
As a valued WebSphere Application Server customer who has contacted technical support, we are hoping you will find this information useful.
This note contains links to WebSphere Application Server technical support documents and information that can help you obtain value from your software. It is intended to help you to be proactive in your support and administration of WebSphere Application Server.

    • 1. Don’t be caught by surprise – try the IBM Support Portal today
      On January 6 the new IBM Support Portal, a unified, centralized view of all technical support tools and information for all IBM software, replaces the existing software product support pages. You can tailor the Support Portal to suit your needs, focusing on the software and hardware products you care about and organizing the pages to reflect the way you work. The portal makes it fast and easy to find the information or tools you need to prevent and resolve problems.We hope you can take a few minutes to fill out a short questionnaire that evaluates the IBM Support Portal in comparison to the existing IBM support website pages. We appreciate your feedback!

      9. One plug-in config to handle multiple Portal Applications in multiple Portal Clusters
      I have different Portal applications running in 2 different Portal Clusters. I want to use only 1 IBM HTTP Server Web server to route requests correctly for both applications in both clusters. How can I configure the Web server plug-in to accomplish this?

      12. Solution for installing 32-bit Java SDK fix packs on IBM HTTP Server V7.0 using Update Installer 7.0.0.5 and earlier
      For most operating systems and architectures, you should install the 32-bit Java SDK fix packs for IBM HTTP Server V7.0, even if that IBM HTTP Server was installed from the 64-bit Supplemental installation image. However, due to a defect in the process, Update Installer V7.0.0.5 and earlier will not allow you to install the 32-bit Java SDK fix pack, and will erroneously allow you to install the 64-bit Java SDK fix pack instead. This technote explains how to address this problem.

如何在一台服务器上部署多个相同url的应用?

2009年12月15日 hashei 2 条评论

现在的服务器性能越来越强,内存动辄4G、8G,而32位JDK下,单个java堆一般不超过1.7G。那多出来的内存怎么办?建垂直集群(Vertical clusters:垂直集群是指同一机器上部署多个服务器,充分利用硬件资源)可以,简单的部署多个appserver也行。但是应用如何处理?如果多个项目都需要用相同的context root,比如说/,那怎么办?

其实做过网站的朋友都知道,一台服务器上一般不可能只放一个网站,那如何访问到这些网站,有三种方法:

  1. IP不同,一个网卡上绑定多个IP,不同的IP对应不同的网站。
  2. 端口不同,不同的网站运行在不同的端口上。
  3. 虚拟主机不同,通过不同的虚拟主机名(一般都是域名)来访问。

那对于webshpere或者weblogic,很明显可以实行的是上述第三种方案。部署应用时会让我们选择部署到哪台虚拟主机,默认的都为default host,所以我们只要新建一个虚拟主机,名称一般为域名。那么就能实现通过一级域名直接访问应用。即使一台app server上部署了多个应用。

这种设置对于提供互联网服务的应用尤其有效,因为大家本来就是通过域名来访问的。而且即使只有一个应用,设置非默认的虚拟主机名可以起到只能通过域名来访问,而IP地址访问则会得到应用服务找到的错。虽说提高的安全性不多,但能满足年底全市各部门关于“只能通过域名访问,而IP无法访问”的要求。

至于内网用户,可以在内部dns上配置域名解析,或者编写hosts文件,达到同样效果。

更新:对于webshpere,我测试下来即使不同的虚拟主机,相同的上下文根也无法同时启动。在日志里会看到已经有重复的Context root了,这样的话只能配置apache使用它的虚拟主机解决

服务器备份软件Acronis True Image介绍

2009年12月9日 hashei 没有评论

临近年末,各种考评将至,于是各单位信息中心开始“操心”数据安全,加之近期电信、移动严厉打击黄色信息,各领导也害怕黄色信息附带的病毒、木马危害数据安全,所以分外重视数据的备份。重要生产环境的数据当然早就做过全面细致的备份工作,但是一些不怎么重要的服务器,托管在机房的单独web服务器,采用Veritas等未免成本太高,所以这里介绍Acronis的备份产品。它们的产品线也很丰富,从单机到多台服务器应有尽有,价格应该可以为一般企业接受。

备份软件介绍

1.1概要:

Acronis True Image Echo Server for Windows

Acronis® True Image Echo Server for Windows可以在物理和虚拟环境中进行灾难恢复和系统迁移,为中小企业及远程办公室/分公司提供更大的灵活性和价值。

1.2 特点
  • 不中断服务器运行的即时服务器磁盘备份
  • 即时纯粹空机服务器还原
  • 还原单个文件或文件夹
  • 备份和升级服务器驱动器
  • 自动排程服务器磁碟影像
  • 建立增加服务器磁盘备份影像
  • 嵌入式磁盘备份影像核查
  • 磁盘备份影像确认在服务器恢复之前New!
  • 文件系统确认在服务器恢复之后 New!
  • 查看服务器磁盘备份日志 New!
  • 电子邮件或弹开通知 New!
  • 命令行服务器磁盘备份管理控制台 New!
  • 支持窗口动态容量
  • 支持 FAT16/32, NTFS, Linux Ext2, Ext3, ReiserFS, XFS, JFS New!
  • 支持 SAN, NAS, RAID, 磁带驱动器, CD/DVD, 网络驱动器与其它备份储存
  • 自动化的驱动精灵操作

其中不中断服务器运行的即时服务器磁盘备份、即时纯粹空机服务器还原、建立增加服务器磁盘备份影像、支持 SAN, NAS, RAID, 磁带驱动器, CD/DVD, 网络驱动器与其它备份储存这四个特点能满足目前项目服务器备份的要求。

2 备份方案介绍

结合备份的要求和Acronis True Image Echo Server for Windows软件的特点,制定了如下的备份方案:

l 在每台需要备份的服务器上安装Acronis True Image Echo Server for Windows

l 在服务器中划分10G的空间作为Acronis Secure Zone(划分大小根据你的数据量定),存放备份内容,这10G空间将变成隐藏空间,无法访问。以后备份的内容都在这10G空间中,当空间不足时老的备份内容会被覆盖。

l 制定每月一次全备份,每周一次增量备份的备份计划。

l 激活Acronis Startup Recovery,方便系统出故障后的备份还原。

l 备份一份最初的内容到DVD光盘,同时制作一张可引导备份光盘,以防万一。

什么是真正的思考?

2009年12月6日 hashei 没有评论

      正常的人生出来便懂得思考。不过,人虽有思考能力,但并非人人都晓得如何进行独立思考。人云亦云,思路不清,都是由于缺乏独立思考。要发展和培养出个人的独立思考,关键在掌握一套有效的思考方法。这里转载“思方网”的几篇“思考方法的内容”,希望于人于己都有所裨益。

AIX环境下安装DB2 9.1及Inforsphere information integrator

2009年11月30日 hashei 没有评论

曾经的这篇《WebSphere Information Integrator安装过程》是windows下的安装过程,图片么google相册被挡住了,我也懒得再改。

这次是在AIX下安装DB2 9.1版本,从准备操作补丁到修改内核参数,安装完整数据库。安装完DB2后安装DB2 Infosphere information Integrator(也就是之前的WebSphere Information Integrator)中的Replication Server。

DB2数据库安装准备

1、使用bootinfo –K来确认是否是64位内核。如果没有请按以下内容更改:

要切换至 64 位内核,需要 root 用户权限并应输入下列命令:

ln -sf /usr/lib/boot/unix_64 /unix

ln -sf /usr/lib/boot/unix_64 /usr/lib/boot/unix

bosboot -a

shutdown –Fr

2、安装操作补丁:

xlC.rte 8.0.0.4和 xlC.aix50.rte 8.0.0.8

  • 技术级别(TL)5300-04 和 Service Pack (SP) 5300-04-02 及以上

在操作系统光盘可以找到安装,如果没有的话可以到IBM网站下载
