Could not reserve enough space for object heap
Hi Guys,
I am a newbie to Dynatrace software. I installed Dynatrace 4.1.0 on my local machine. I can start Dynatrace web server agent and analysis server but cannot start Dynatrace Server. I attached the screen of error message and piece of server log. Is there any body having the same issue? Could you please help me out here? 
The server log:

It sounds like you are out of memory on your machine. For getting started purposes, just run with the dynaTrace server service started. You do not need to start up the Analysis Server or the collector service. Those are "extras" for "real" installations. For demo purposes on your machine the server service is all you need.

Thanks for quick help here, Rob! I just tried to stop web server agent, collector and analysis server and tried to only start Dynatrace Server but the same error shows and the same server log stating not enough space for object heap. My machine has 3 GB of ram. And now i only use about 30% of CPU
Hi Wanqi -
So next steps... How much free memory do you have (using Task Manager or something to see)? the dT server will come up wanting to allocate around 800M for its JVM. Do you have that much free?
You could lower this manually, by editing the server's startup INI file. Go here:
C:\Program Files\dynaTrace\dynaTrace 4.1.0\dtserver.ini
and you will see the arguments -Xmx and -Xms. You can try lowering them to 512 to see if that gets you started.
Does that let it come up?
Problem fixed! My dtserver.ini initially allocates 1536M to the arguments -Xmx and -Xms. I lowered them to 768M. Now i am able to start the server! Thanks so much, Rob!
just a little background about your JVM problem:
if you start a (HotSpot) JVM as a 32-bit process, you'll only be able to allocate around 1400M of heap at most. if you try more you get the error as seen above.
if you start it as a 64-bit process (requiring a 64-bit OS and 64-bit CPU, of course), you'll be able to allocate basically all the memory you've got left.
best,
Christian
