4 Configure the Installed Session Delivery Manager Cluster
After you have installed an Oracle Communications Session Delivery Manager standalone server or cluster of OCSDM servers, use the following sections to configure them.
An
OCSDM cluster is
comprised of multiple server nodes (members), each of which can be a candidate
node for your file systems, databases or applications. Each cluster node
monitors the health of other cluster nodes. If a node fails, another node in
the cluster takes over services for the failed node. For example, when an
interruption or failure occurs in a critical application on a node, a
high-availability cluster combats this disruption by switching application
operations to another node within the cluster to quickly and seamlessly prevent
a complete system failure.
Note:
In an OCSDM cluster, the R226 compliance value for each node must be the same or the cluster cannot start up. As each node of the cluster starts up, if there is any mismatch on this value, the cluster startup fails. Cluster nodes that fail due to a mismatch of R226 compliance value require a complete OCSDM re-installation.
