Question

系统详细信息:

Windows 7 Professional
Processor :Intel Core i3
RAM: 3GB
System Type : 32 Bit Operating System.

PDI 版本:

pdi-ce-6.0.0.0-353

执行的步骤:

 1. Extracted the Zip File pdi-ce-6.0.0.0-353.zip into G:\ Drive
 2. Created Environment Variable PENTAHO_JAVA_HOME and set value to C:\Program Files\Java\jdk1.7.0_79\jre

从 cmd 执行 Spoon.bat 时收到错误:

默认情况下，spoon.bat 中的 XMX 参数值为 2048M。它没有启动Jre，所以之前我将其更改为256M。突然我尝试更改在spoon.bat文件中的XMX参数值从XMX256m到Xmx1024m，并且wola它工作。不知道这个 XMX 代表的原因或逻辑，也不知道这里应该有什么值在数学上支持您的系统配置。
