在 64 位上发送 ctrl-break 到 java 进程 Windows ala sendsignal 在 32 位上

Question

I frequently use the sendsignal tool for WebSphere Application Server processes (server, launchClient, wsadmin, etc.) in order to generate heap dumps. However, sendsignal doesn't work on 64-bit machines. Does anyone know of an alternative for sending the ctrl-break to a remote process?

Update: Bengt points out that this is basically the same as the following question. So, I guess my question is: has anyone found a way around this limitation in the past two years?

Can I send a ctrl-C (SIGINT) to an application on Windows?

Answer 1

Why use a control break for the dumps why not use the commands that are provided precisely to do this kind of activity?

$AdminControl invoke $objectName generateHeapDump

This provides you with the required info and you get the dumps that you are after.

Latest comments link to working x64 versions for windows 2003 and windows 2008 too:

(2013-9-26): Both, the 32-bit and 64-bit EXE versions can be downloaded from the following link: https://github.com/walware/statet/tree/master/de.walware.statet.r.console.core/win32 -- GeorgeP (2014-3-7): I built both 32-bit and 64-bit version with Ctrl-C, it's called SendSignalCtrlC.exe and you can download it at: https://dl.dropboxusercontent.com/u/49065779/sendsignalctrlc/x86/SendSignalCtrlC.exe https://dl.dropboxusercontent.com/u/49065779/sendsignalctrlc/x86_64/SendSignalCtrlC.exe -- Juraj Michalak
