Overview

The General Application Smart Assist (GASA) is a pre-installed Smart Assist that comes with PowerHA® SystemMirror®. Its intended purpose is for configuring applications that do not already have a target Smart Assists, but can be easily managed via start and stop scripts.

The general Smart Assist requests the minimal amount of information from the user and will configure the PowerHA SystemMirror resource group and application controller necessary to support the target application. The GASA Smart Assist has only one Smart Assist component; more complicated Smart Assists will have several components. All of the concepts and tasks associated with creating a single component Smart Assist can be extended and applied to constructing a Smart Assist with multiple components.

The add screen for the Smart Assist associates a resource group to a set of participating nodes selected by the user. Inside the resource group is an application controller constructed via the Smart Assist In the sections that follow we'll dissect the General Application Smart Assist into the sub-tasks required to create a new Smart Assist.
