Information about ClearCase Remote Client (CCRC)



A ClearCase VOB server can be aliased and if this host has a problem, then a new host can be configured using the same alias name. This cuts down the time a view or VOB needs to be restored, reregistered, tagged and allows the new host to be ClearCase functional in a short amount of time.

However, with CCRC the physical hostname is used by the CCRC clients so aliasing the hostname or clustering is not currently supported in CCRC. The CCRC view references are tied to the hostname and not the alias name of the host so restoring the views to an aliased hostname is not an option.
