Configuring Message Server Cluster Using
Server Admin Service
Pramati Server provides the following ways to configure Message Server Cluster:
• Using the Server Administration Service
•Modifying XMLs
Before configuring the cluster, the Message Persistence tables should be created. Run the
scripts in
<install-dir>/jms/templates. You can modify the table names in the scripts to match
the names specified for the four message persistence tables. Table names should be unique
to a Message Server cluster to avoid conflicts among various standalone Message Servers and
clusters since the same tables will be used by all the nodes of the cluster.
The following tables store runtime information required to persist messages.
• Message table -This table stores all persistent messages.
• Subscriber table -This table stores information about all subscribers.
• Subscriber Message table -This table stores messages of all subscribers.
• XA table -This table stores information about messages produced/consumed as part of
distributed transactions.
