VCS and its agents run on the same systems as the applications. Therefore, VCS attempts to minimize its impact on overall system performance. The main components of clustering that have an impact on performance include the kernel; specifically, GAB and LLT, the VCS engine (HAD), and the VCS agents. For details on attributes or commands mentioned in the following sections, see the chapter on administering VCS from the command line and the appendix on VCS attributes.
