Is the constant part of the memory reserved using the xmx parameter?

Question

In java, we can determine the maximum memory that a process can take with the xmx parameter. For perm gen, we can define MaxPermSize. Thus, perm gen space is also part of the xmx allocated memory.

so xmx = young + old or young + old + perm OR young + old + perm + stack space?

Answer 1

So, perm gen space is also part of the memory allocated using the xmx parameter.

No space
