VCS service group

A set of resources working together to provide application services to clients. For example, a Web application service group might consist of: disk groups on which the Web pages to be served are stored; a volume built in the disk group; a file system using the volume; a database whose table spaces are files and whose rows contain page pointers; the network interface card or cards used to export the Web service; one or more IP addresses associated with the network card(s); the application program and associated code libraries. VCS performs administrative operations on resources, including starting, stopping, restarting and monitoring at the service group level.
