Software Cluster node

A Software Cluster node represents a "self-clustering" grouping of one or more logical hosts into a logical group. "Self-clustering" software is software that provides its own clustering capability, for example, BMC Discovery clusters. A a Software Cluster node, which acts as a logical container for the Software Instances (SIs) representing the software running on individual hosts. Software Cluster nodes are under the full control of patterns.

For detailed information about patterns, see the The-Pattern-Language-TPL and Configipedia.

Software Cluster node lifecycle

The following section describes the scenarios in which a Software Cluster node is created, updated, or removed.

Creation

The creation of a Software Cluster node is under the full control of patterns. Software Clusters are created when an SI representing a manager or a member of a clustered software application is created. A relationship link is automatically created to the Host node and the Cluster will have a key generated.

The generated key for a Cluster node is entirely dependent on the kind of Cluster.

Update

The update procedure for a Cluster node is also under full control of patterns. When the pattern has identified a cluster, it calculates a key. If a Cluster node with that key already exists, it is updated accordingly.

Removal

A Software Cluster node can be destroyed either manually or automatically. Software Cluster nodes are automatically removed when the last remaining manager or member SI is destroyed or aged out. For more information on SI aging, see Software-Instance-node.

This is a Cascade Removal type, see Cascade Removal.
