User preparation on Solaris hosts

On Solaris SPARC hosts, users must include /usr/ucb in their search paths. A user whose search path does not include this directory cannot use the clearmake Sun compatibility mode (–C sun) and may experience problems in other contexts that require access to standard system-supplied programs. For example, if /usr/ucb is not in your search path, then whoami is not accessible, with the consequence that some scripts run by xclearcase fail.
