Except, at times, for space management issues. We often have very fragmented volumes and a person cannot get a large primary allocation. We now preach "use a smaller primary and secondary allocation, and let dynamic volume count save you from an x37 abend." > o CA/CI splits (especially CI splits) don't have as big an impact as they used to. And despite being told this, they still insist on weekly reorgs to eliminate them. Another preaching point that is ignored. > o allocating on Cylinder vs Track boundaries don't have a > major impact anymore, due to define extent > o they still don't understand block sizes Which makes PS-Es nice since the don't have the same "problem" with blksize since the "logical" blksize and the physical blocks on the DASD are "decoupled". > > It may be an 80-column mind, but I think it's more that > nobody spends money on education, these days. Steve will agree with you on that! > Hum, then how come the "old timers" don't seem to know these things either? And, at least here, we have preached to them on many occasions. But, then, they are "too busy" to learn.
