Old Things and News from SDTEric Poinsignon , IT/API AbstractHistory and news from the SDT service. History and stories...Once upon a time, in 1992 in the ECP division, PT group (Programming Techniques) led by Paolo Palazzi in building 1, an "embryo" of SDT service was created, but nobody knew at that time it was a service.Arash Khodabandeh started this "service" with 2 tools: StP and Artefix. RD13 used Artefix, a tool based on Petri nets that generates software code. It was the first time a generated code was running for the test beam, and it worked! The first purpose of this service was to give access and promote some commercial software engineering tools. They could be tested for own benefits as the tools were paid centrally by Gottfried Kellner, who was working for the ECP division. 50 different tools have been put in production or evaluated during nine years. As SDT was not defined as a service, there were no servers, no
disks and no resources allocated to it. So the tools were installed
on the Sun group server: An annecdotic story at that time, is problem we had with power supply, because the power switch was near the light button and either some house-cleaners or others didn't take attention, or just wanted to test this funny buttons. This was not so "annecdotic" for our users, and, after some catastrophic recovers, we finally get our UPS (Unit of Power Supply) to secure the machine. One other day, a system warning fell in the mailbox saying some files were missing. As the operator was going through the file system, files were disappearing at the same time. The decision was taken to save all the 30 Giga bytes. It was certainly the best solution because after the backup, all the files disappeared. We reconfigured the file system with a mirror and now when a disk crashes it is transparent to the users. Today...The service and the server are now located in building 513, in IT/API group.Pttools is still distributing the tools
and licenses, and the uptime of the server reaches regularly more
than 300 days.
