BigDataLite 2.4.1 java.lang.OutOfMemoryError：PermGen空間

Question

我是初學者，嘗試使用Oracle大數據NoSQL MoviePlex動手實驗，並且在加載電影數據後嘗試加載索引頁面時遇到同樣的錯誤進入NoSQL。以下是JDeveloper中顯示的錯誤消息。

我甚至增加了基本內存到12000MB，因爲我被告知，這可能會解決這個問題，但仍然會有這個錯誤。

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

鏈接到動手實驗：http://www.oracle.com/technetwork/topics/bigdata/articles/intro-to-oracle-nosql-db-hol-1937059.pdf

任何人都可以幫助我嗎？

感謝，
安

你需要找到該文件setDomainEnv.sh/home/oracle/.jdeveloper/system11.1.1.6.38.61.92/DefaultDomain/bin/下，並對其進行編輯。

找到字符串WLS_MEM_ARGS_64BIT="-Xms256m -Xmx512m"（我發現它的兩倍）和-Xmx512m之後添加"-XX:PermSize=256m -XX:MaxPermSize=256m"，這樣它看起來像：

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

之後，重新啓動JDeveloper。
