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

Solution .1.

The solution is to point WebLogic at a 64-bit JDK. This can be done by editing {weblogic install}\user_projects\{your_domain}\bin\setDomainEnv.cmd. My solution was to add this around line 64:

set JAVA_HOME=C:\software\jdk1.6.0_27

Solution .2.

with following memory args (setDomainEnv.cmd):

set USER_MEM_ARGS=-Xmx2048m -XX:PermSize=512m -XX:MaxPermSize=1024m

Solution.3.

here is how to fix it:
Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System

Variables->New: Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M

Variable name: Path
Variable value: ;C:\Program Files\Java\jre6\bin;F:\JDK\bin;
Change this to your appropriate path.
