Since I am working on my method-GAPP (see method-GAPP overview presentation) I have been challenged with the task to model a real system and not a Lab system with a programmed load profile. The big issue with a real system is that the load profile is changing all the time and the only thing we can recognize are periods of time we have a not to changing workload profile. For example an OLTP system will do during production hours from 9:30 in the morning till 11:30 and from 14:00 till 16:00 in the afternoon comparable things, but will do from 01:00 till 06:00 in the night something totally different. The given example could match maybe some OLTP systems but could be totally different for your OLTP production system. Continue reading
