PPM Server Memory Management
A node in a PPM server cluster runs in the context of a single Java Virtual Machine (JVM). We recommend that you use a server cluster configuration, with multiple nodes, to improve reliability and performance.
Using multiple nodes in your configuration enables you to do the following:
-
Support increased user load
-
Improve capacity
-
Maintain and provide acceptable performance
You can increase the capacity of a PPM instance by adding more PPM nodes. To meet the availability needs of the organization, you can distribute these nodes in the PPM cluster across one or more physical hosts.
