The proper, (and probably cheaper) answer to this problem is to add another smaller CPU to the mix, if you have only 2 CPUs, CICS can't really take advantage of all of the processor complex as it could. It's almost certainly cheaper to add more engines than to upgrade, unless you have an older box or got a really bad deal. Depending on the box, you can pick up CPU's on the 3rd party market for almost laughably small prices.
In this case, costs should drive your decisions, not misplaced estimates of capacity. Do you really have individual CICS tranactions that exceed 50 mips? Probably not, and it could be just a matter of tuning what you have. It always surprises me that a lot of sites think upgrade before tune, (not that you're one of them), but I realize that IBM is a big proponent of the upgrade instead of tune philosophy. :) Brian ---------------------------------------------------------------------- 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
