The embedded Prolog was ProLog by BIM, from BIM Systems, which was the Belgian-based competitor to a US-based company called Quintus, in Mountain View; both offered high-end Prolog systems for Unix. One of the things that ProLog by BIM had was the ability to have Prolog use Oracle or Sybase databases as if they were Prolog's own native database (Spooky23, if you see this, I was wondering if that helped you use DB2 in this fashion when doing your Tivoli work or did you roll your own from scratch?) Anyway, Tivoli apparently created a macro language, TEC, that was then compiled down to Prolog to run. Here's an opinionated look at TEC and the decision to use Prolog: http://www.softpanorama.org/Admin/Tivoli/TEC/tec_rules_programming.shtml http://www.softpanorama.org/Admin/Tivoli/TEC/tec_rules_progr... Some more info/perspectives from back-when about Tivoli's use of Prolog: https://groups.google.com/forum/#!topic/comp.lang.prolog/LgMyadsawME https://groups.google.com/forum/#!topic/comp.lang.prolog/LgM...

Yes! Thanks for remembering! Those BIM features were unknown to us as we had no BIM manuals. We took some open source code in a mailing list that let you dynamically load shared libraries. That's how we interacted with the DB2 client, and we also did a similar thing with Perl so the admins could do some work for us. The IBM macro stuff was mostly there to power their (Motif based) rule builder GUI and was pretty limited unless you pre-processed events upstream and spoon fed it. That's why the IGS guys struggled -- they were certified against the base product (and had minimal experience beyond installing the thing) and the salespeople were aspirationally selling whatever one of the big financial services places did with the product. It's been 15 years so I'm hazy but I'm pretty sure I tossed most of the macros that shipped with the product. It was a really fun gig and I learned a lot from it.
