Re: z/OS Change Management / Change Control Procedures

Search on ITIL  ITSM  change management itSMF and you'll be
swamped.
http://www.itsmfusa.org  would be a place for you to start

You could buy the ITIL Service Support manual from itSMF-US for $US100 or
so,
and use the 50-60 pages on Chg Mgt as a start for operational change mgt
procedures and basic best  practice guidelines
(Release Mgt covers software release whether OS, apps, sys sw, etc)

Procedures are not oriented to a particular platform.  Have been adopted
by at least one US-based global TLA outsourcer for their chg mgt procedures
as an example.

Process defginiton and procedures grew out of IBM's Information Systems
Mgt Architecture from the late 1970's/early 80's.  Were adapted to UK whole
of govt in the 80's and now extended around the world.  Wealth of material
covering procedure, guidelines, watchouts, process flowcharts, attributes,
benefits, problems, how to implement, relationships between ITSM
disciplines
(Service desk/incident mgt, problem mgt, change mgt, config mgt,
release mgt, capacity, DR, SLM, availability, financial, security).
Standard is BS15000 in UK and AS8018 in Oz, and heading towards ISO.

Greetings!

  I'm trying to look up some sample change management / change control
procedures for operating system and system/subsystem utility changes, but
I'm not having much luck in a Google search (or a search of IBM-MAIN, for
that matter).  I'm pretty sure they'd have to be more rigorous than
application CCPs, if only for the wide-ranging impact those changes can
have.

  Does anyone out there have some sites/samples/examples of workable
operating system CCPs?  If so, I'd appreciate a copy or a link.  Many
thanks.

  Doc Farmer

Running z/OS 1.4 on a G5/G6 after 31 March 2007

[Peter Greening]

Folks
Hoping that you can cure my ignorance re implications of z/OS 1.4 end of
support date,
or at least direct me to the path to enlightenment pls.

We may choose to run on an unsupported version for say, 6 to 9 months after
Mar-07
on an Amdahl Millennium server.  We ran on 2.10 for 6 months past the use
by date, and
for different  reasons this time, may have to do the same.

Are there technical, architectural, marketing, IBM/ISV software, hardware
compatibility,
or any other constraints on running this O-O-S environment in a parallel
sysplex with
other machines that are all planned to be z/architecture by March 2007?
Currently there is a mix of z800/900, G5/G6, and Amdahl in the sysplex
without any issues.
How would end of support disrupt our environment (e.g have to be cast out
of the sysplex?)
or the other z/arch environments (e.g constraint on their use of
features/facilities/upgrades ?)

i've trawled and have only been frustrated at my seeming inability to find
anything
meaningful from the arrangement of keywords to do with support,
coexistence, sysplex,
z/OS, etc.  Only reference i've found so far is that z/OS 1.4 can coexist
with z/OS 1.5, thru
 1.7, but nothing about parallel sysplex.

thx and regards,
