This question is related to
java
By using the -Xmx
command line parameter when you invoke java.
See http://download.oracle.com/javase/6/docs/technotes/tools/windows/java.html
Following are few options available to change Heap Size.
-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
-Xss<size> set java thread stack size
java -Xmx256m TestData.java
Use -Xms1024m -Xmx1024m to control your heap size (1024m is only for demonstration, the exact number depends your system memory). Setting minimum and maximum heap size to the same is usually a best practice since JVM doesn't have to increase heap size at runtime.
-XmxSIZE
For example: -Xmx1024M
Java command line parameters
-Xms: initial heap size
-Xmx: Maximum heap size
if you are using Tomcat. Update CATALINA_OPTS
environment variable
export CATALINA_OPTS=-Xms16m -Xmx256m;
Start the program with -Xms=[size] -Xmx -XX:MaxPermSize=[size] -XX:MaxNewSize=[size]
For example -
-Xms512m -Xmx1152m -XX:MaxPermSize=256m -XX:MaxNewSize=256m
