Commands for the CoreGroupManagement group of the AdminTask object

Use the Jython or Jacl scripting languages to manage deployed applications. The commands and parameters in the CoreGroupManagement group can be used to create and manage core groups. A core group is a high availability domain that consists of a set of processes in the same cell that can directly establish high availability relationships. A cell must contain at least one core group.

For more information about the AdminTask object, see the Commands for the AdminTask object article.
