"Error occurred during initialization of VM" while starting weblogic

"Error occurred during initialization of VM" while starting weblogic

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

I have lowered my heap to below values

set DEFAULT_MEM_ARGS=-Xms768m -Xmx768m
set PORT_MEM_ARGS=-Xms768m -Xmx768m

instead of

set DEFAULT_MEM_ARGS=-Xms512m -Xmx1024m
set PORT_MEM_ARGS=-Xms768m -Xmx1536m

in the file middlweware_home\Oracle\Middleware\user_projects\domains\your_domain\bin\setSOADomainEnv.cmd

Then, start the weblogic and it works fine!
