Could not reserve enough space for object heap. Error starting SOA server after installing in Local

I installed SOA server domain . When i tried starting the server i encountered the following error.


Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.


I went ahead and changed the

this value set DEFAULT_MEM_ARGS=-Xms512m -Xmx1024m

to

set DEFAULT_MEM_ARGS=-Xms512m -Xmx700m

This mean we are reduced the memory allocation from 1024MB to 700MB.

After this setting my server is able to start again.
