Table 10 Cache server configuration
Description Files
This file contains JGroups configuration that is used by the cache servers to
form a cluster. The following are some salient features of this configuration: nsasj-udp.xml
1. The transport protocol that is used to form the cluster is UDP.
2. The cluster is formed on a multicast address that is obtained from the user
during product setup. The multicast port is used to form the cluster is
BASE_PORT+7
.
For more information on JGroups protocols, see http://jgroups.org/
manual-3.x/html/protlist.html .
NOTE: There is no NonStop specific configuration in this file.
This file contains configuration for the different caches that are configured in
the cache server. The caches that are configured here are used as remote stores nsasj.xml
by the local cache configuration in the cache container defined in the Infinispan
subsystem configuration in domain.xml. The following is a snippet of the
cache configuration and the Infinispan subsystem configuration in
domain.xml

NOTE: The cache server defines a named cache by name remote-ejb that
is referenced in the remote-store configuration in domain.xml.

Post Master configuration files
The Post Master is a component that exchanges data between the EJB client and the NSASJ Server
instances. The socket that connects the Post Master and the NSASJ Server is configured as a JI
socket, whereas, the socket that connects the EJB client and the Post Master is a normal TCP socket.
