I have worked in a couple locations that are smaller than you mentioned. 3 LPARS, 10-12 CICS images, DB2. We had 4 in both locations. Following is the general breakdown of tasks. Fortunately there was very little turnover.

At one shop I worked, (10 sysplexs, 44 LPARs, 20+ CECs), the CICS person was Actually 5 people). The z/OS sysprog was 8 and the Oracle(DB2/IMS) person was 6. In my current environment, all of the below is 4. HTH, <snip> CICS is generally one person. Oracle is generally one person as well. z/VM and Linux - one or two primary people, depending on the number of VMs and Linux instances. The z/OS sysprogs are capable of pulling double duty here, but that may be cutting it to close. You do not mention performance and capacity, storage management or web services. Shift coverage, sick time, vacations, etc. are other considerations. With a variety of skill levels, the number should probably be between 15-20 people if you include the skills and issues that I mentioned. With highly experienced systems programmers in all of the above disciplines, 10-15. Less than 10 would affect your shop's ability to meet schedules *or* would probably lead to burnout. </snip> ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- 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
