Configuring Message Server Cluster Using
XML
You can configure Message Server Cluster in Pramati Server in the following ways:
Using the Server Administration Service. For details, read ‘Configuring Message Server
Cluster Using Server Administration Service
Modifying XMLs as explained in this chapter.
Before configuring the cluster, run the scripts in <install-dir>/jms/templates to create the
Message Persistence tables. 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.
Configuring Message Server Cluster using XML
To configure a Message Server cluster using XMLs use the following steps:
1 Create a new folder, say ‘jmsc1’ under the <install_dir>/server/nodes.
2 Copy the ‘config’ directory from <install_dir>/server/nodes/<server_name> and place it
under <install_dir>/server/nodes/jmsc1. This copies the
server-config.xml.
3 Copy the cluster-config.xml from <install_dir>/server/templates and place it under
<install_dir>/server/nodes/jmsc1.
4 Open the server-config.xml, and make the following changes:
