在weblogic上部署的项目，在迁移的时候，通常必须迁移到相同版本的weblogic容器上面去，那怎么看当前weblogic的版本号呢？两个方法：第一，查看weblogic的安装日志，里面包含版本号；第二，查看weblogic主目录下面的registry.xml文件，里面包含版本号。

安装日志

weblogic的安装日志log.txt 一般在weblogic安装目录的根目录下面的logs文件夹下面

里面内容比较少，主要包含weblogic安装时安装的组件和中间件等，每个组件都有对应的版本号

该weblogic安装于 2015-5-30 8:39:37，安装的weblogic 平台为 10.3.5.0，安装在了 D:\Oracle\Middleware\Oracle11g_Home 目录下

包含了四个大的组件：

版本号为 7.2.0.0 的 Common Infrastructure Engineering

版本号为 10.3.5.0 的 WebLogic Server

版本号为 10.3.3.1 的 Oracle Configuration Manager

版本号为 3.6.0.4 的 Oracle Coherence

各组件后面的子组件，也标注了是否已安装。

registry.xml

registry.xml里面和安装日志里面是类似的内容

上面讲的就是查看weblogic版本号的两种方法，第二种方法，通过查看registry.xml 更通用些，它就在weblogic的根目录下面。
