I have TR6 running on several customer machines with no reported issues. A
couple of them do heavy I/O and also have RAID 6 with hot spare turned on.

Hey all,

On 12/7 - 12/8, we loaded TR6 to our production LPAR and on Monday we found a general performance degradation of 30% which continued through the week.

Knowing that an IPL can destroy temporary indexes, we didn't become concerned until we noted that the degradation continues into this week.

We had some new indexes slated for implementation, which we did today. It was a long-shot and (so far) hasn't paid the hoped for dividends. We grabbed a DBMon on Friday morning, but haven't had a chance to dig into it yet.

I hadn't noticed any buzz concerning TR6 and performance (and found nothing in the archives), but I need to ask those of you that have applied TR6 or
TR7 if you had any performance issues or knowledge on some new setting or something that I should look for.

Planning a PMR to IBM, but thought I'd give this vast collective wisdom a chance...does anyone have anything for me?
