Issue 2
How to increase memory fot print when running GMU utility on a windows desktop
Client error: “Execution failed. Reason: Java heap space:
 
It relies on a couple of things.

1. How much memory do you have in the system? And how much is available. Have you checked Taskman? Right click near the clock on the windows task bar, Start Taskman. Check memory.
2. If you have plenty of memory and you just need to add additional memory to java,

 
(open a command prompt type "set" Find the version of Java_home. ) Or you can look at the taskman process list possibly while GMU is running to determine the o/s Java being used.
 

3. Configure your O/s Java

Open Windows Start => Control Panel => "Java" Double click go to the Java tab in the Java Control Panel. Click the View button to view the runtime settings. And to add more JAVA memory I have done the following in the past
 
Runtime Parameters: -Xms256m -Xmx6144m
To increase my Max Heap to 6Gigs. You need to A) Ensure you have enough memory B) Validate which version of java you need to update the runtime parameters. C) Add a larger Max Java size.
