The fact that the z13 is the fastest microprocessor currently existed just doesn't penetrate their mind because the original S/360 was designed in the 1960s. All the comments in this thread, in addition to this particular story, really make me wonder if CSC (our "cloud sourcer" and "IT department replacement?") is really going to be able to take our current z/OS processing and port it to some sort of cloud based system, cost efficiently. From rumors that I've heard, our users have already raised some voracious objections because, according to them, the "new" system would take a week to do what we currently do in a day. In insurance, paying valid claims quickly is a big plus when you're a small company. As another said in this thread, our z/OS system is COBOL / CICS based and uses VSAM. Worse, we had some very clever programmers who wrote code which actually reads the data in some VSAM AIX data sets (not via the PATH, but the AIX itself as if it were a regular VSAM data set) to do some of the processing more quickly (i.e. have an AIX on a field, then read the AIX itself to answer the question "how many customers have this value in that field?", equivalent of SELECT COUNT(field) FROM database WHERE field='SOME VALUE'). > Regards, > Tom Conley > > -- Schrodinger's backup: The condition of any backup is unknown until a restore is attempted. Yoda of Borg, we are. Futile, resistance is, yes. Assimilated, you will be.
