Install a New Session Delivery Manager Cluster

You can install a high-availability (HA) cluster of SDM servers to ensure reliable, continuous data and operations by masking both planned and unplanned downtime and preventing single points of failure without compromising availability.

An SDM 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.

Ensure that you do the following tasks before you start a new SDM cluster installation:

1. See the Session Delivery Manager Software Distribution Media section in the Oracle Communications Session Delivery Manager Release Notes, Release 8.0 for more information about the names and descriptions of the software files that you need to do this upgrade.
2. Download the SDM application image file to a directory to each server (cluster) node on which you are installing SDM.
3. Unzip the application image file on each server node in the cluster. See the Unzip the Tar File to Create the Installation Directory section for more information.
4. Start the installation and complete the Typical Installation on each server node in the cluster. See the Start the New Cluster Installation section for more information.
5. After the Typical Installation on each server node in the cluster is complete, see the Configure a New Cluster in the Custom Installation chapter for more information on associating the cluster nodes that you installed with each other so that they can function together as a cluster.
