Xrs reduce use of OS signals by Java/VM (see documentation) Xfuture enable strictest checks, anticipating future default Xbootclasspath: set search path for bootstrap classes and resources -Xbootclasspath/a: append to end of bootstrap class path -Xbootclasspath/p: prepend in front of bootstrap class path -Xnoclassgc disable class garbage collection -Xloggc: log GC status to a file with time stamps Here's what the output of those commands looks like from my JVM: You can find more options for controlling Java application memory use by looking at the output of the java -X command. (The important part here is the -Xm圆4m portion of the command.) More Java memory-related command line arguments Where THE_CLASSPATH and PROGRAM_NAME are variables set earlier in my script. Use this syntax to specify the amount of memory the JVM should use:
The short answer is that you use these java command-line parameters to help control the RAM use of application: Java memory FAQ: How do I control the amount of memory my Java program uses (i.e., Java RAM usage)? The short answer Contact me at (al) at valleyprogramming (dot) com for details.
