It's mostly the LPARs that run Endevor that had issues in the past (I haven't look at this in years). I recall Sam Knutson trying to work with Endevor support on the orhpan / fragmented storage left in the initiator. >Has this reduced you S822 abends? > Probably a few, but prior to this enhancement and in the days before we used WLM inits, we recycled JES2 inits a few times a day and there was also automation to recycle an INIT anytime after an abend (that code also was changed to work with WLM inits too). This is one of those no-brainer enhancements. It doesn't hurt to set it. Even a "bad setting" doesn't leave you worse off than you were prior to setting it. At worse case, with values too low, you would recycle the initiator after a single job ran in it and cause some extra overhead. If you set the values too high, it's like you haven't done anything at all and would still see some S822 abends.
