任何人都可以給我一個暗示我做錯了什麼?來自命令行的OpenJDK核心轉儲?
因此,在Redhat(亞馬遜AMI實例)上,我試圖獲得正在運行的應用程序的核心轉儲。即使遠程端口處於開放狀態(並且JMX服務器已正確配置),我仍無法從jconsole.exe或jvisualvm.exe的windows框連接到JMX端口。我不知道爲什麼,所以我試圖直接從JVM獲得核心轉儲(Cntrl- \ did not work)。所以,這裏是我如何設置的核心轉儲,但它不起作用,我不知道爲什麼。
[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,調試器運行後,我嘗試創建一個使用此轉儲,但它失敗:
[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
