I just read in the November/December issue of CommUNIXations an article on page 14 about an application-level implementation of an OLTP system called Tuxedo. The article says that "...servers are single-threaded and not re-entrant. Thus, there is no system support for maintaining 'state information' although an application may provide this support..." I presume that this is done for faster performance but I am not sure why it would be faster. Would someone explain this? Also, what is meant by "single-threaded"? Aren't all individual processes single-threaded (multiple processes may take separate paths through the text image)? And what "state information" would the system maintain for re-entrant code that would be useful to an application? ---------- Thanks, Mike Anderson ..!uunet!sean!mka
