The response i got back from the data management group was that (at the time) it would still cost $26m for training, education, documentation, etc ... even if i provided fully integrated and tested implementation. the claim was that i wouldn't be able to show the necessary ROI for the $26m since customers would just buy the equivalent in fba that they would have ben spent on ckd (no incremental revenue ... and therefor no ROI). the issues about life-cycle costs with regard to maintaining ckd (and life-cycle savings converting to fba) were discounted. other posts mentioning ckd, fba, multi-track search, etc. http://www.garlic.com/~lynn/subtopic.html#dasd one of the first "costs" was trying to get some of the eckd kludge to work for various things ... like speed-matching buffer (aka 3880 supporting attaching 3380 3mbyte datastreaming, to 168/3033 1.5mbyte channels). a couple recent posts on the subject: http://www.garlic.com/~lynn/2007e.html#40 FBA rant http://www.garlic.com/~lynn/2007o.html#54 mainframe performance, was Is a RISC chip more expensive? including this old email reference mentioning problems getting eckd for speed-matching buffer working http://www.garlic.com/~lynn/2007e.html#email820907b ---------------------------------------------------------------------- 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
