我可以自动重启tomcat jvm内存异常 [英] Can I auto restart tomcat jvm on out of memory exception

问题描述

我知道这不是最佳做法，但我想知道如果我部署的应用程序抛出一个内存异常，我是否可以自动重启tomcat

I know that this is not "best practice" but I would like to know if I can auto restart tomcat if my deployed app throws an outofmemory exception

推荐答案

您可以尝试使用OnOutOfMemoryError JVM选项

You can try to use the OnOutOfMemoryError JVM option

-XX:OnOutOfMemoryError="/yourscripts/tomcat-restart"

还可以生成堆转储以供以后分析：

It is also possible to generate the heap dump for later analysis:

-XX:+HeapDumpOnOutOfMemoryError

小心结合这两个选项。如果强制在tomcat-restart中终止进程，则堆转储可能不完整。

Be careful with combining these two options. If you force killing the process in "tomcat-restart" the heap dump might not be complete.
