Back to some of Ray Wicks old SHARE papers. The Big Pitcher come to mind. Today's tuning is an amalgam of hardware, software, architecture and prestidigitation. Craig Mullins has new v6 of DB2 Guide thru v9 and v10. http://www.craigsmullins.com/cm-book.htm He references some available tools and has several tuning tips and observations. For us the old Platinum tools(now CA) were life savers for DB/2 and SQL bottle necks. Updated Redbooks to include new SSD devices give impressive gains in thru put for most work loads. The dreamer's dream is a self tuning system. Some sites do it by fiddling with WLM by shift or load or letting CoD fire up another processor still a good bit of manual observation and configuration.

It's my opinion it's a good tool for cpu bound application, a bit less for discovering elapsed time issues. Finally, I use a set of tools to do the job, SMF, monitors, APA etc. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
