配置weblogic7cluster遇到灭绝人性的错误：bea-150009

687614

他这里报adminserver和managed server的listen address 或port冲突，但我抱着对社会主义IT平台的高度负责的态度仔细检查多次，没有冲突的地方；我是用weblogic 7 sp2和weblogic 7 sp3做的集群;
我的配置是这样的：
adminserver: 192.168.0.1:7001
proxyserver: 192.168.0.1:7003
app1: 192.168.0.1:8001
app2: 192.168.1.1:8001
app1可以正常启动，app2启动是报如下异常！
192.168.0.1是linux主机，192.168.1.1是hp-ux;

1. 是不是不同版本的weblogic不能做集群？
2. 如果我现在想下载weblogic 7 版本，要到哪里去下？

问题已解决：原因是由于weblogic platform sp2和weblogic platform sp3不能成功搭建集群，为什么我也很奇怪，到meta-link上看根本没有sp3这样一个版本；

一直对wls的cluster不太了解，这次试了发现：
1. 不同操作系统的wls可以搭建集群(原来一直以为操作系统类型、版本要一致)；
2. 忽略以后的性能问题不说，相同版本不同厂商的jdk(这次试的是wls自带 jdk1.3、hp jdk1.3)不太影响wls cluster的搭建；
