Good morning all,
I am pondering the difference, (Performance-Disaster Recovery-More/Less volumes), for JES2 spool datasets. We are at z/OS 1.7 in one dev LPAR and I am starting the cloning/building process for our production LPAR. We are a mid-size shop with (4) mod-3s used for JES2 spool in a z/OS 1.4 production environment. With all four volumes, we have a little over 12,000 cylinders for spool and keep three days output before offloading to tape. We are hovering around 65-75 percent utilization for the most part during the week. Since I can take advantage of the 'Large Dataset Support' for JES2 now, what are the pros/cons of having one mod-27 versus 2 mod'9s? Besides the 9,000 or so cylinders. I would like to 'enlarge' the JES2 spool environment we have and would like to hear your opinions on this matter. Any and all would be appreciated. Best regards, Claude Richbourg ---------------------------------------------------------------------- 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
