Increasing java heap size general

Question

I'm using a Windows 7 PC and i want to increase my java heap size but not for an application So the command java -xmx4g e.g. is not possible. I want to increase the java heap size in generel. Is this somehow possible? I appreciate every answer.

Sorry for my bad english

PS: I'm using 64-bit JVM on a 64-bit Win 7 PC commands -java Xmx6G and set JAVA_OPTS=-Xms1024M -Xmx6144M does not work even when writing it in the startup.bat I get the error in a program that consists of 10 same steps the first 4 are no problem but after the 4th i get the error. Error: javax.xml.ws.soap.SOAPFaultException: Java heap space

So you want to change the default value for the maximum heap size on your machine? — isnot2bad, Nov 20 '13 at 14:22

It's only possible on 64-bit JVM and 64-bit Windows, on 32-bit JVM / PC max heap size is about 1.2M

I am using 64-bit JVM and 64-bit Windows I also tried the option with the system variable JAVA_OPTS but it's not working – user3013419 Nov 21 '13 at 12:51
I also have Win7-64 and Java 64-bit, java -Xmx4G test.Test1 works fine – Evgeniy Dorofeev Nov 21 '13 at 13:13
yeah but like i said i dont want to have it on anything in particular like test.Test1 i need it for everything so the command java -xmx6G does not work without something behind it – user3013419 Nov 21 '13 at 13:46
make sure it is -X and not -x in the first place – Evgeniy Dorofeev Nov 21 '13 at 14:30
