I would like to know how many resources my company will need to host a list. We have MVS and Unix machines available. I would appreciate any input that might help me advise my boss. Specifically, I would like to know: How much disk space? How much cpu? How many hours (per week/month) does an Administrator spend on it? Why choose MVS over Unix (if both exist)? Other? You can mail to me directly and I will submit a summary or I will happily read along. peb Phillip E. Bronsdon Online Computer Library Center, Inc.
