&Computer Services Outsourcing (some say we started it, but I was nt here then so Ill defer on that question)::Senior Infrastructure Specialist&?xxx?xxx?xxx?3?xxx?xxx?6?xxx?xxx?9?10?11?xxx?xxx?xxx::We have lots of mainframes where I am, but theyre all pretty boring. The boxes I ticked above relate to a new IBM mainframe app that was migrated from a Unisys platform about 6 months ago. It has a web front-end - no WAS, but CICS directly talking to midrange web servers.&?xxx?1?xxx?xxx?xxx?xxx?6?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx::Mostly we dont migrate stuff off mainframes, but occasionally a client will do so. The boxes above relate to a particular client moving a single customer-facing app onto a Unix box.&It was deemed more cost-effective to move this app onto Unix. Im not so sure, but thats what the stated reason was.::&Unix - AIX I think, although it could be Solaris.::&Mainly its I/O throughput.
<BR>
<BR>A second major benefit is the toolset - the others cant compete with the wide array of automation/monitoring/management products.
<BR>
<BR>Relability/Availablity/Serviceability is also a consideration. Weve touted Sysplex for yonks, but had no nibbles. Just recently we may have heard that finally the RAS of Sysplex will be exploited, but Ive heard that before so Im not counting my chickens yet.::&We have several mainframes. one runs a very large Bank, another two run very large federal Govt departments.
<BR>
<BR>In total, I would estimate around 2-3 million individual end-user-driven transactions daily from all our mainframes. Thats probably a low estimate.
<BR>
<BR>The people served are basically the whole of Australia (21 million people) - even the kids use ATMs or internet banking these days.::&We dont really have any mainframes like this. There are a couple of small LPARs on a couple of our mainframes that would qualify, possibly only several thousand TSO transactions for sysprog development.
<BR> <BR>Sysprogs are about two dozen people here.::&?xxx?xxx?xxx?xxx?xxx?5?xxx?xxx?xxx::We have nine active mainframes in one city, another in another city, and two more in each of three other cities (these three cities are overseas, but we manage their capacity planning).<BR>Two of the 9 mainframes here have IFLs and ICFs (one of each on each box). Another five of the nine here have ICFs. We dont have any zAAPs or zIIPs yet - the latter may come into play when we understand them better.&We measure lots of things. Cost per MIPS, cost per LPAR, cost per CICS region/DB2/IMS/MQSeries subsystem, FTE per MIPS, downtime per year (scheduled and unscheduled).::&Give us all your I/O - we wont drop any. <BR> <BR>We are Always On. <BR>::&Theres not a lot of good news here, sadly. Basically we get some occasional recogition when things dont go badly after theyre expected to not go badly, and if they go badly we always get a kicking. <BR> <BR>Thats the price you pay for always being On, I suppose.::&Drop the price. Dont stop dropping them either, IBM, or youll lose out.::&Not Familiar.::&Sorry to be late responding, I dont read z/Journal as often as I should, and only just saw the article from last year (Oct 2005 IIRC).::&?0?xxx?xxx::peter.bishop@eds.com Not Scored by Definition
