Had an interesting situation ... IDS 12.10 engine had most of the sysmaster tables/views "disappear." This impacted a number of ops, including archives, etc. Some of the tables were there, so an engine bounce didn't attempt a recreate of the sysmaster database. Of course I recreated the missing tables with "buildsmi" fine. Anyone had this behavior though? Of course we have no scripts that ever try to manipulate sysmaster tables/views. Thanks!
