Command-Line (Per Application)
1. Open a command window (Windows) or terminal/shell window (Unix/Linux) and navigate to the application you wish to run.
2. To indicate an initial heap size, run your program with the following parameters:java -Xms
(your application command line)For example, to run MyApp.jar with a starting heap size of 64 MB, you would run it like so:java -Xms64m -jar MyApp.jar

3. To indicate a maximum heap size, change your command line to the following:java -Xms
-Xmx
(application command line)Assuming we want the example from step two to run with a maximum heap size of 128 MB, use the following command line:java -Xms64m -Xmx128m -jar MyApp.jarThis will ensure the application starts off with a minimum of 64 MB of heap space allocated for it, and never tries to allocate more than 128 MB.
