我使用Windows server 2008 r2在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收到错误，重启失败。
从服务器日志：

我曾尝试修改setenv.sh中的内存设置：
JAVA_OPTS="-Xms512m -Xmx1024m -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled"
并没有显示任何效果 我还能做什么呢？
答案 0 :(得分：0)
您似乎已按照此答案的第二个选项：https://stackoverflow.com/a/10392385/1530814
因为它显然不适合你，为什么不试试第一个选项呢？
-XX:MaxPermSize=SIZE_VALUE
