BTW, a good z/OS performance tuning expert - is someone who knows what each person they talk to means by "poor performance" - has a thick skin - recognizes "good performance" based on the lack of hearing "poor performance" - is aware of the performance characteristics of all IBM and non-IBM middleware, esp. when installed on non-z platforms but talks to z/OS. (How else can you explain that it isn't z/OS's fault?) - understands the interrelationships of those products - likes things that are shiny - can predict to within 3% the effect of a turning a just-discovered configuration/tuning knob - can predict to within 5% the effect of replacing a product with a competitive product - actually knows the answer to "5% of what?" - knows all of the tuning Hints and Tips accumulated over the last 40 years - can put his or her hands on performance reports showing "performance anomolies" for any time in the last 5 years. - knows "whether you're getting your money's worth" without knowing how much was actually paid
Remember the discussion about the 12 AMP power-up limit in "Apollo 13"? If it reached you on an instinctual level, you have what it takes to tune z/OS for a fast IPL. I know, this is just *how* you walk under buildings while lifting them, but implementation details are important. :-) Alan Altmark Sr. Software Engineer IBM z/VM Development ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
