BigDataLite 2.4.1 java.lang.OutOfMemoryError：PermGen空间

Question

我是初学者，尝试使用Oracle大数据NoSQL MoviePlex动手实验，并且在加载电影数据后尝试加载索引页面时遇到同样的错误进入NoSQL。以下是JDeveloper中显示的错误消息。

我甚至增加了基本内存到12000MB，因为我被告知，这可能会解决这个问题，但仍然会有这个错误。

这些都是工具和平台，我使用： -
BigDataLite 2.4.1 - 的Oracle VM VirtualBox
了Oracle JDeveloper 11g第1版

链接到动手实验：http://www.oracle.com/technetwork/topics/bigdata/articles/intro-to-oracle-nosql-db-hol-1937059.pdf

任何人都可以帮助我吗？

感谢，
安

你需要找到该文件setDomainEnv.sh/home/oracle/.jdeveloper/system11.1.1.6.38.61.92/DefaultDomain/bin/下，并对其进行编辑。

找到字符串WLS_MEM_ARGS_64BIT="-Xms256m -Xmx512m"（我发现它的两倍）和-Xmx512m之后添加"-XX:PermSize=256m -XX:MaxPermSize=256m"，这样它看起来像：

WLS_MEM_ARGS_64BIT="-Xms256m -Xmx512m -XX:PermSize=256m -XX:MaxPermSize=256m". 

之后，重新启动JDeveloper。
