Memory Args:What does -Xmn stand for ?

Our server starts with following

MEM_ARGS=
-Xmn519m -Xms1559m -Xmx1559m -XX:MaxPermSize=128m -XX ermSize=128m -XX:+DisableExplicitGC -XX:NewSize=320m -XX:MaxNewSize=320M -XX:SurvivorRatio=8

Question: What does -Xmn stand for ? Is it one of the -XX:NewSize -XX:MaxNewSize ? If so does get nullified by
-XX:NewSize=320m -XX:MaxNewSize=320M mentioned later.

So now the server is running with NewSize as 519 m or is it still 320 m?

For example in HP JVM which comes from Sun JVM -Xmn replaces -XX:NewSize parameter. So in your case, I think, New Generation will have 519M.

When You asking questions about JVM, it will be easier to answer You if we will know which JVM do You use (Version, Vendor)
