It doesn't depend on number of MIPS. It depends on: - number of jobs - number of environments (application instances, z/OS images) - environment complexity - change activity (new releases) - BUT NOT MIPS. Real life examples: a) modern company. Number of MIPS grew up approx 40 times, number of environments grew up 25%. Approx 400 000 jobs monthly, quite complex dependencies. Two folks on the beginning, now ...also two folks. b) old company. No job scheduler! Few hundreds MIPS, environment functionally stabilized (very few, very small changes in the application). Schedule table consist of few pages, it's printed by administrator, jobs are submitted by operators. The operators are mostly responsible for many other things (printing, ftp transmissions, backups), so real FTE cost is ZERO. c) huge government organisation. They started with homegrown, poor tools for scheduling and 20 person staff responsible only for batch. Now they have commercial job scheduler ...and the staff grew up. -- Radoslaw Skorupka Lodz, Poland -- Tre tej wiadomoci moe zawiera informacje prawnie chronione Banku przeznaczone wycznie do uytku subowego adresata.

Re: Question on Job Scheduling
if it's a 24x7 shop, with 1 lead/mgr per shift, that sounds about right for any size unless workload is large. --- On Fri, 2/10/12, Dan Gillis gillis...@gmail.com wrote: From: Dan Gillis gillis...@gmail.com Subject: Question on Job Scheduling To: IBM-MAIN@bama.ua.edu Date: Friday, February 10, 2012, 3:28 PM I have a meeting with a customer next week to talk about z/OS batch job scheduling.

I promise not to reveal where I got any of this information from, I only want the statistics. Thanks, Dan Gillis System z Client Architect, IBM I think it depends on the complexity of the schedule. How many request jobs vs. scheduled jobs. Type of scheduling software (home grown, CA ESP, CA Scheduler, IBM Tivoli, etc) And whether or not you include distributed scheduling in the mix. We have 3 schedulers running about 5000 jobs a day in CA-ESP both mainframe (1 plex) and distributed. The schedules are simple. The calender is simple. We are small. In a previous life I worked in a shop with 15 Sysplexes and about 100 schedulers. for Mainframe Only. With very complex schedules. Very little adhoc.

Re: Question on Job Scheduling
Dan: Contact me off line, if you would. Some questions are: Is the zSeries only or z and LUW? Do they schedule for more than one environment? The obvious question; How many batch processes are scheduled, on average? Do they support lots and lots of on request and on demand jobs? Do they have a high abend rate? What workload automation tool are the currently using? Do they have an automated change management tool that automatically implements changes into production?
