任何人都可以给我一个暗示我做错了什么?来自命令行的OpenJDK核心转储?
因此,在Redhat(亚马逊AMI实例)上,我试图获得正在运行的应用程序的核心转储。即使远程端口处于开放状态(并且JMX服务器已正确配置),我仍无法从jconsole.exe或jvisualvm.exe的windows框连接到JMX端口。我不知道为什么,所以我试图直接从JVM获得核心转储(Cntrl- \ did not work)。所以,这里是我如何设置的核心转储,但它不起作用,我不知道为什么。
[ec2-user bin]$
jsadebugd 2504 -F Attaching to process
ID 2504 and starting RMI services,
please wait... Debugger attached and
RMI services started.
因此,调试器运行后,我尝试创建一个使用此转储,但它失败:
[ec2-user ~]$ jmap -dump:live,format=b,file=dump.t 2504
2504: Unable to open socket file:
target process not responding or
HotSpot VM not loaded The -F option
can be used when the target process is
not responding
[ec2-user ~]$ jmap -dump:live,format=b,file=dump.t 2504 -F
Attaching to core -F from
executable 2504, please wait... Error
attaching to core file: Can't attach
to the core file
