Thus when it runs, it has the effective user-id of root and the effective group-id of informix so that it can access the raw device without letting anybody else access it: -rwsr-sr-- 1 root informix 366592 Sep 19 1991 /usr/informix/bin/tbinit +----------------------------------------------+---------------------------+ | Rich Casto, Bellcore, Piscataway, NJ, U.S.A. | email: rc@cc.bellcore.com | +----------------------------------------------+---------------------------+
