Java Virtual Machine is a piece of software that is responsible for running Java programs. Adding more JVMs helps in running more of the software requests.

When to add more?

The first thing to check is the total CPU usage and the memory used by the process called java.exe. If the CPU is not near maximum and the memory used by the java.exe is at the maximum defined and there is additional memory (RAM) on the server, you can add more JVMs.

How do I add more JVM?

JBOSS: If using JBOSS application server, search for the file config.yml in the /App/Depconfig/properties/external directory and change/add the following section (the example creates a two JVM environment):

jboss:

domain:

enabled:

true cluster: 2

How many JVM can be added to a server?

The number of JVM that can be added is dependent on the number of CPUs on the server. In theory the number of JVM can be number of CPU + 1. Ensure that the total memory allocated to all JVM is not greater than the RAM available.
