Creating application CRGs
If you have applications in your high-availability solution that you want to be highly available, you can create an application cluster resource group (CRG) to manage failovers for that application.
You can specify to allow an active takeover IP address when you create the application CRG. When you start an application CRG that allows for an active takeover IP address, the CRG is allowed to start.
To create an application CRG, use the Create Cluster Resource Group (CRTCRG) command and specify *APP for the CRGTYPE keyword.
