List - I have gone through a few manuals and cannot determine the answer to the following questions. Any guidance is appreciated
1) Can the SDB be adjusted from half-track to another setting (quarter or full)? 2) Are there any new best practices for SDB that have changed in the last 20 years? 3) Is Half-track still considered OPTIMUM? Since the storage arrays are so fast, I would think that maybe full track would not be that much of a performance impact any more. I have been working offlist with a couple of people with JCL and BLKSIZE and SPACE Sizing. I am trying to figure out how to make the formula more accurate. When I calculate space - I use full trace blocking. However, I find when SDB uses half-track, my math is off. Any thoughts or help would be great.
