runInstaller 报错：Memory fault
最近在一个客户那里安装9iforAIX，结果运行runInstaller报错如下：security properties not found. using defaults.stackpointer=42ba1f70Writing Java core file ....Written Java core to /tmp/javacore434372.1262950584.txt/tmp/OraInstall2010-01-08_07-36-16PM/installer: 434372 Memory fault(coredump)在metalink没有找到一样环境一样报错的情况，于是检查了很多相关的设置，包括操作系统的补丁和内核等等，没有发现问题。只可能是安装介质的问题了，结果重新上传了安装介质，安装成功。[@more@]
