    Has anybody come up with any figures for the effects of the z15 integrated sort accelerator, either for Reorgs or SQL activity?

    We haven't made the corresponding DFSORT changes required and left the UTILS_USE_ZSORT Zparm set to the default of NO when it was introduced.
    We subsequently found out that SQL usage of the accelerator is enabled by default with the PTF for APAR PH31684, even if the DFSORT changes are not made. I was researching new columns in the Omegamon "warehouse" tables and came across the SORTL columns. Delving a bit further I discovered that we'd "missed" the SQL PTF and so this is now implemented and active everywhere, including production.
