How Can I Adjust JVM Memory Size?

Understanding JVM Memory Allocation

Question:

Can I adjust the JVM memory size for my application and if so, how?

Answer:

Yes, it is possible to increase the JVM memory. When starting the JVM, you can specify the initial heap size with the -Xms parameter and the maximum heap size with the -Xmx parameter.

For example:

java -Xms128m -Xmx256m MainClass

In this command, the JVM will initially start with a heap size of 128 MB and increase it to a maximum of 256 MB if necessary.

Verifying JVM Memory Size:

To determine the current size of the JVM, you can use the jmap command along with the process ID of the JVM.

For example:

jmap -heap com.program.MainClass
