tomcat - Tomcat 上的 MobileFirst Platform Foundation Server，出现 permgen 错误

Question

我在装有 Windows server 2008 r2 的 Tomcat 上完成了 IBM MobileFirst Server 6.3 的安装，并成功部署了我的第一个 war 文件。接下来我创建了第二个运行时，从服务器配置工具部署了不同的 war 文件并重新启动了 Tomcat。 Tomcat 出错，重启失败。

来自服务器日志:

我曾尝试通过 setenv.sh 修改内存设置:

JAVA_OPTS="-Xms512m -Xmx1024m -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled"

并没有显示出任何效果。
我还能做什么？

看起来您已经遵循了此答案中的第二个选项:https://stackoverflow.com/a/10392385/1530814

既然它显然不适合你，为什么不试试第一个选项呢？

-XX:MaxPermSize=SIZE_VALUE
