安装datastage是报“Out of memory”

在安装windows 的datastage 8.0时报错如下：

[**Out of memory,aborting**]

[]

[***panic:JVMST062: Cannot allocate memory in initializeFRBit()]

Thist application has requested the Runtime to terminate it in an unusual way.Please contact the application's support team for more information

网上查了很久，有一个是安装IBM JRE也报此错误，试着按他的方法处理了，过了，原来是“IBM_JAVA_OPTIONS”这个变量。

处理方法如下：

1. Open "Control Panel"
2. Double-click on "System" icon in "Control Panel"
3. Click "Advanced" tab in "System Properties" panel
4. Click "Environment Variables" button
5. Click "New" button in "User variables for userid" in "Environment
Variables" panel
6. Input "IBM_JAVA_OPTIONS" in "Variable Name" input field, and "-Xmx512M" in "Variable Value"
7. Click "OK" button, and close all panels
8. Try again
