IDS 9.4 (soon to be 10) AIX 5.3 IBM P560 with several LPARS IBM DS4300 Storage Array I've been revisiting the tuning information this week. We're migrating to different hardware now, and that will be followed quickly by an IDS upgrade. We have a heavily used OLTP system. What are the current target values for Buffer Wait Ratio, Buffer Turnover Rate, and Read Ahead Utilization?

None of the targets have chaged, AFAIK. -- Bye now, Obnoxio "I don't read newspapers anymore except the local rag which I do weekly to cheer myself trying to see if anyone I hate has been stabbed." -- Horribilis XVI -- This message has been scanned for viruses and dangerous content by OpenProtect(http://www.openprotect.com), and is believed to be clean.
BR: < 7 - Smooth sailing < 10 - Rough seas > 10 - SLOW GOING BTR - single digits are good. I like to keep it under around 6 turns/hour or once every 10 minutes. That seems to keep things humming. RAU - As close to 100% as possible. Even 99.00 is suspect. Art S.
