How to get heap dump of Tomcat running as windows service.
Hi,
We have web server hosted on Tomcat 7.0.22. Tomcat is running as windows
service.
When we try to get the heap dump of Tomcat using the following command
*jmap -dump:format=b,file=heap.bin <pid>*
we get below error
*<pid>: Not enough storage is available to process this command.*
When Tomcat is started manually in console (using command “catalina.bat
start”), we are able to take the heap dump.
Is there any workaround which would allow to take heap dump when Tomcat
running as windows service?
Thanks & Regards,
Aditi

Hi
If you are connected to the Windows machine through remote desktop,
please try to connect to it using the console session (administrative
credentials required).
This is because starting with Windows 2003, services run with service
isolation, but you can get around that by connecting to the console session.
Depending on your operating system version (not the server's version),
you can connect to the console session by
After Windows XP SP3, Vista SP1
From the Start menu, choose Run. Type "mstsc /console". Connect
to the server as usual.
Other versions
From the Start menu, choose Run. Type "mstsc /admin". Connect
to the server as usual.
Hope it helps.
Best regards

Hi,
Please find the requested details below
1. What is your OS?
*Windows 7, 32-bit OS. I have even tried on Windows 2k8 server but the
same problem.*
2. How much memory the running Tomcat is using? Do you have enough
space on your hard drive, and does it have access rights to write
there?
*Running Tomcat is using around 247MB and JvmMx is set to 512 MB. There is
enough free disk space available.*
**
*Tomcat is running as the logged on user account and therefore should have
access rights.*
*Also, did not login to machine as remote desktop session. I logged in to
the machine directly.
*Any help appreciated.
Thanks & Regards,
Aditi

Maybe you could try configuring the service to run as specific user
(instead of Local Service account).

Tomcat heap = 512M according to your earlier post, is that correct?
jmap heap = 512M (according to the command above).
I suspect jmap heap needs to be greater than Tomcat heap maximum
which is why my original suggestion was to use '-J-Xmx1024M'
Please try it with 1024M as originally suggested.
What JVM version are you using to run Tomcat?
What JVM version are you using to run jmap?
These should be the same.

Hi,
Tried below option.
* jmap -J-Xmx512M -dump:format=b,file=heap.bin <pid>*
This too gives the same problem *"<pid>: Not enough storage is available to
process this command"*

try:
jmap -J-Xmx512M -dump:format=b,file=heap.bin <pid>
(You _might_ get away with 768M but better to be safe than sorry).
I believe jmap is telling you that it doesn't have enough heap
available to process tomcat's heap - which you have
set at 512M. The default heap is typically quite low.

make some more disk space available, sufficient to permit the heap to be
written to file.
