But the OP is complaining that that strategy is not working. And that experience/observation is in line with my own.
That is, even trained, experienced operators are making an unacceptable number of mistakes. We have to drill down to find root causes. Here I think the most reasonable attack is to simplify what the operators are expected to do. And that means shifting the responsibility for making critical system changes to a sysprog. With a combination of locking most loved LPARS and reducing the operator involvement to clicking on an 'activate' icon, I would daresay the error rate would drop to near zero. No process is perfect, but this basic strategy has worked for me in the past. A key to success would be an unchanging operator script with absolute minimal use of the word 'if'. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Tom Marchant Sent: Wednesday, October 01, 2008 10:57 AM To: [email protected] Subject: Re: HMC Management Best Practices On Wed, 1 Oct 2008 09:25:56 -0500, Hal Merritt wrote: ..snip You are right back where you started. People make mistakes. If operators are properly trained, they can certainly make these kinds of changes as well as anyone. Indeed, I would argue that the opportunities for error are reduced if all HMC operations are performed by the same people, rather than spread some of the tasks among different groups. -- Tom Marchant NOTICE: This electronic mail message and any files transmitted with it are intended exclusively for the individual or entity to which it is addressed.
