6. F.Momal / LHC-IAS-FS What worked well General stability Easy to install Easy and fast applications development Easy to maintain Easy to extend Product evolved according to the market Bugs were generally solved in the following release

7. F.Momal / LHC-IAS-FS Problems Instability with the X Windows sessions. Impossibility to have a session at home. Some hardware failures. Hard to write reusable code. Backward compatibility was not perfect. Difficulties to debug network problems. Difficult to use built-in database connection

8. F.Momal / LHC-IAS-FS Why changing ? Europeans systems were now existing. Market trend seemed to be drifting towards Windows NT. Windows NT stability OK. PCs are powerful enough. Windows based standard appearing (OPC). Cost

9. F.Momal / LHC-IAS-FS Windows advantages Cheaper: hardware, software and maintenance People are used to the system Large amount of programs to add functionality –compilers –drawing programs –math tools Interoperability standards
