I have a Java application that I run from a console which in turn executes an another Java process. I want to get a thread/heap dump of that child process.
On Unix, I could do a kill -3 <pid> but on Windows AFAIK the only way to get a thread dump is Ctrl-Break in the console. But that only gives me the dump of the parent process, not the child.
还有其他方法可以获得堆转储吗?
Is there another way to get that heap dump?
推荐答案
假设您知道 pid，您可以使用 jmap 获取任何正在运行的进程的转储.
You can use jmap to get a dump of any process running, assuming you know the pid.
使用任务管理器或资源监视器获取 pid.那么
Use Task Manager or Resource Monitor to get the pid. Then
jmap -dump:format=b,file=cheap.hprof <pid>
获取该进程的堆.
