Components of NSASJ
The following list describes the various components of NSASJ:
•
NSASJ Server: A server is a single instance of NSASJ Java EE container that provides an
implementation of a specific set of Java EE technologies. It is configured as a TS/MP serverclass
and all the instances of the server share the same configuration and file system resources.
•
Host Controller: Each installation of NSASJ has only one instance of Host Controller which
also serves the purpose of a Domain Controller. It is configured as a TS/MP serverclass with
only one instance and serves as the single point of management for all the NSASJ Server
instances.
•
Infinispan Cache Cluster: Each installation of NSASJ has only an Infinispan cache server
defined as a TS/MP serverclass. The purpose of this component is to store and share state
information across the instances of NSASJ serverclass. An example of state information is the
