Hi everyone, I could say the same that a colleague in Oracle DBA but I come from of world IBM zOS mainframe (15 years experience in System area). I would like to start in the same field (Big Data & Analytics) but looking at the data analytic from data coming from IBM mainframe platform. So, which would be the best way to start? . (I'm familiarized with SMF records and I'have worked with other solutions like BSM (Business Service Management) and BSLM (Business Service Level Management). I would be grateful to you any suggestion on this matter. Thank you very much for your remarks.
