Gil, I don't think this one is necessarily a quality issue. As widespread as the problem is, it appears to me to be more of a huuuge oversight. That said, you are correct in that we don't know what IBM plans to do, or for that matter, even how much of an impact fixing this will be on performance of z/OS. My concern is that since we (as well as probably many of the sites on this board) are bumping against our cap and if we get hit by even a 10% reduction in thruput from this, we're in danger of missing SLAs and other fun TLAs.

This might go a step beyond: "We did it wrong, so we'll raise the price to make it right." In fairness, we don't know what IBM plans to do. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN The information contained in this message is confidential, protected from disclosure and may be legally privileged.
