Java Virtual Machine Launcher

[stigmata101]

Hi

i have a problem that is becoming a pain, BTW, love the server besides the issue below.

basically i install the software and it runs. next time i boot up my pc i get the following:

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

the only way i can get rid of it is to uninstall UMS and Java, Reboot, reinstall JAVA and then UMS.

however, the next time in boot up it gives the same error.

i am running windows 8

any help would be appreciated.

If you get the error message "Could not create the Java Virtual Machine" here is how to fix this problem.



When that happens, the easiest solution that has been tested on both Windows XP, Windows 7 and Windows 8 is:


• Open the Control Panel

• Go to System

• Go to Advanced Systems Properties

• Then Environment Variables

• In System Variables, click Add

• New Variable Name: _JAVA_OPTIONS

• New Variable Value: -Xmx512M

• Click OK










That's it, your Java program should now be able to execute properly.
For those interested, Java -Xmx/s is the configuration parameter that control the amount of memory Java uses.

• Xmx sets the maximum heap memory size

• Xms sets the minimum heap memory size




See http://www.jafaloo.com/2011/10/30/java-xmx-memory-setti... for more details on Java Heap memory size and parameters.

Hi djmajicmixx

thanks for that, i will try it out tonight, never even switched the PC on last night

one thing, during the wizard i set the memory option to 1536, basically double the default. would that have any effect?

What version of windows 8 are you running, x64 or 32bit?
You shouldn't touch the Java Heap Settings during install as the default is what's been tested to work and setting anymore than default will just be wasting the global java heap pool of resources.
To change the value back to 768 it's better to just reinstall UMS, but you can change the value in the Registry (if you want to do it that way i'll post it)
