Multiple Processes

[Pradeep Kadambar]

I tried to do some searching on a query from a friend of mine. If suppose I run multiple instances of a java program (same or different) will there be single or multiple instances of JVM running, assuming all these setup being on the same macine.

I feel that there will be multiple instances of JVM as we specify JVM congigs seperately during program launch.

If it were to be running on the same JVM .... can we achieve better memory management for the machine.

This may ease the GC process too...

A JVM will be initialized whenever someone (script/command line/process) calls the following executable:
<jdk_root>/bin/java
with a valid fully qualified class name.
