AIX 安装数据库故障
在AIX上安装DB2 V9.5时，执行./db2setup之后，图形界面出来闪一下就没有了，发现java是32的版本，修改了JAVA_HOME变量指向64位版本的位置后，能出来安装界面，但点击安装按钮后，安装界面又没有了。在/tmp下可以看到db2setup.err 和 db2setup.log等文件，以及dump输出的javacore开头的.txt文件等。
db2setup.err的内容：
Unhandled exception

后在http://heliosguneserol.wordpress ... 11gr2-installation/中看到，在AIX安装oracle时也发现了此问题。显然应该是AIX的问题，不过，在另外一台AIX系统中（相同安装介质和版本），未发现此问题，但出问题的系统上已经安装了JAVA6，不知是否是这个引起的。
使用如下命令可以解决此问题：
export JAVA_COMPILER=NONE
