This section explains how to customize the AIX version High Availability Cluster Multi-Processing.
Throughout this section, the primary node is the active node in the Resource Group that executes Managed Server transactions, and the secondary node is the standby node in the same Resource Group.
The secondary node A defines the node which creates the environment of Managed Server transactions first in the secondary nodes in this cluster resource group. The secondary node B defines the remaining secondary nodes in this cluster resource group.
The customizing work of a primary node and secondary node A is executed as a 1:1 standby system, a mutual standby system, and a n:1 standby system.
The customizing work of a primary node, secondary node A and secondary node B is executed as a cascade topology system.
Example
When creating a cascade from three sets of nodes, one set is a primary node, one set is the secondary node A, and one set is the secondary node B.
When creating a cascade from four sets of nodes, one set is a primary node, one set is the secondary node A, and the two other sets are the secondary node B.
