May I take this opportunity for an interesting case study:
I know you all are working in major IT companies and providing support to renowned customers in different field, Telecom, Banking, Insurance.... I am trying to make it generic independent of domain, pls bear with me. Let say you have a product which runs several batch programs in HP-UNIX platform with Oracle DB. For 1 mil transaction to process, your system takes around 8 hrs. to complete. Now the HP vendors (their marketing guys), propose your customer to buy HP-SUPERDOME and assure them that if they runs their system in this platform there will be a huge boost in performance (something may be 1 mil/hr). Your customer is delighted with the proposal and go for SUPERDOME and provide you the project to migrate your system. They may probably contact Oracle to as well for the Data Migration, if they have a separate production contract with Oracle vendors. Now, after the project is completed and started running in production, customer amazingly finds that the performance is still the same as before (even it has degraded further). Please tell me, whom they are going to blame; HP for providing lot of promises and cannot deliver, the system vendor that is you or the Oracle vendor? Most importantly, if customer, is going to arrange a meeting with all those parties, what will be the action plan they can take to mitigate this? Any idea? They cannot simply sit and say a Thank You to HP, I believe as yo
