Weblogic_11g集群搭建
Weblogic_11g集群搭建Weblogic集群部署1.Server⽤过tomcat的朋友应该清楚，当我们有多个项⽬部署在同⼀个tomcat服务器下的时候，我们只需要启动这个tomcat就可以根据⽬录的不同，访问这些应⽤，此时我们⽤的端⼝号不需要改变。
在weblogic服务器中，⼀个server同等于⼀个tomcat。
⾸先我们在创建⼀个server的时候需要给它指定⼀个ip和端⼝（这个ip可以是⼀台远程机器的ip）。
创建好server以后，我们就可以将项⽬部署在其中了。
如果我们有多个项⽬，并且我希望每个项⽬能对应不同的端⼝，那么我们就可以通过创建多个server来实现。
有时候我们称server为'节点'，所以以后听到别⼈说节点的时候也不要茫然，说的就是它了。
2.Cluster这个，就是我们本⽂要讲的重点，集群。
按照我个⼈的理解，集群就是把具有相同应⽤的⼀些server，放在⼀起，统⼀管理。
举个很简单的例⼦，就是我现在有项⽬，我分别放在三个不同的server⾥⾯（先别管我为什么放三个不同的server中）。
那么问题来了，我项⽬要有改动了怎么办？分别去各⾃的server中重新部署？别开玩笑了，万⼀不是三个是⼗个呢？万⼀不是在同⼀台机器上呢（前⾯说了，可以是⼀台远程机器）？我们带着这个问题再来看⼀下集群，放在⼀起....统⼀管理....现在明⽩了吧，这就是集群给我们带来的便利，将这些server加⼊到同⼀个集群当中，如果项⽬有变动的话，我们只需要在部署项⽬的时候，通过集群去部署，那么weblogic会⾃动帮我们将应⽤分配到各个⼦节点中。
3.domaindomian我们有时候也会把它称作为'域'，他就相当于⼀个⼤的容器，⾥⾯可以存放很多server，其中有⼀个默认的server，它会随着域的启动⽽启动。
有⼀点我们必须要清楚，就是当你想要启动某个domain下的server 的时候，必须先启动这个domain。

单击“Done ”按钮完成域的创建。
1.2 配置Weblogic 运行环境1、拷贝文件，将hrms 文件夹拷贝到“F:\weblogic10g\Middleware\user_projects\domains\base_domain”目录下注意：hrms文件夹中有两个文件夹，分别为config和lib文件夹，如图1-2-4所示：图1-2-42、修改config目录下的system.properties文件，如下图1-2-5。
图1-2-53、到D:\weblogic\bea\user_projects\domains\my_domain\bin目录下，用记事本打开startWebLogic.cmd文件，在文件头增加下面语句，因为它是MSSQL2000 或2005的驱动程序，如图1-2-6所示。
『如果数据库是oralce10g时，Weblogic91应用服务器已内置了jdbc for oracle10g的驱动，带下划线的部分就不要了（电子文档中显示为绿色）』。

Oracle提供Coherence,也可做到Distributed caching
Replication Groups
