About 22 years back I got in trouble for recommending we drop Tuxedo Queue with just a database table since we can get all the transactional options for free, just the same, without all the headaches an operational issues involved in connecting all our code with the C++ middleware, especially since Java and PHP were in the mix and Tuxedo was kinda of in it's own world and was pretty much the only non-free software we were using and using in a horrible idiotic way.
