Answer 1

These parameters are passed to JVM via command line: -Xms and -Xmx For more information run java -X.

Answer 2

You can use the JAVA_OPTS environment variable for dealing with java heap size. This variable can be added as a environment variable as well as you can define a configuration line in the startup.bat file.

Add the following line in the startup.bat file.

set JAVA_OPTS=-Xms512m -Xmx512m

You can add this as environment variable as said.

Answer 3

The best place to place these settings is in setenv.bat or setenv.sh in the bin folder. Take a look at a recent SO question on the same topic which has excellent answers.
