请问是什么原因啊！

Answer 1

weblogic922  923安装时默认的ppc目录下的.so时没有可执行权限的

Answer 2

无法打开native IO，造成内存溢出
重新安装，并严格按照weblogic要求打上补丁
启动时将内存设置为合理的范围

Answer 3

好好来学习一下吧............

Answer 4

There are 1 nested errors:
这个不是内存问题吧，我曾经也遇到过类似的问题，应该是你没有正常启动一个domain，重复启动时就会报错。
应该先kill -9 掉这个进程然后在启动，就应该没问题了

Answer 5

重新安装过吧，记得严格按照BEA的补丁要求

Answer 6

本地内存不足，是不是你的-Xmx设得太大了？
