Re: Benchmarking the IPL
Timothy, I saw your post talking about having an A01 warm standby with Z03 CBU. That's similar to what my management is thinking, but without the warm standby. We have EMC storage and it we do synchronous mirroring from our main site to our DR site. Since that is all done via the EMC control units we don't need to have the system up for it. We do want to go to the DR site as needed to do minimal connectivity tests. For those we plan to just IPL the A01 system. Then, when we need to do serious DR tests we would activate the Z03 and IPL that. Basically, the whole purpose of this exercise is to determine how long it would take to be up and ready for those minimal connectivity tests.

If there's no z/VM, then LPAR weights is what you have to work with. I would definitely check out the referenced redbook.

Hi Matan, With regard to your post on this subject which included: SNIPPET RC = TIME(R) SECS = 1800 /* 1800 second you want them to pass */ DO FOREVER N = TIME(E)/*get the time in second which was pass */ IF N = SECS THEN LEAVE END /SNIPPET As Dustin Hoffman said in Hook, bad form. Whilst DO FOREVER is in the manual, IBM do not recommend its use. As Nick correctly points out this will eat CPU cycles, without logically doing anything productive that could not be accomplished by going to SLEEP in the manner alluded to in Ted MacNeil's post. A loop of this type may well be picked up by automation software, with the task being axed as resource hungry. Waiting (SLEEP) allows other work to use the processor in a productive fashion, and is much better for overall though put and service targets.

Hi, Just wondering if anyone had to to any of the previous seminars? Was it worthwhile? Kind Regards, Mark Negotiating mainframe software and hardware contracts Arcati¹s annual seminar on mainframe pricing and contract negotiation takes place on 28th June 2010 at the Premier Inn Touchbase Centre, London Heathrow. As always, the principal speaker is Barry Graham, an internationally recognised authority on mainframe pricing issues. Working with Barry, users with as few as 600 MIPS and as much as 100,000 MIPS have signed contracts saving up to 30% of their expected spend. This year Barry will be joined by David Wilson, independent consultant and former IBM senior executive for System z Software in North East Europe, who will be focusing on what users should do to maximise the benefits of their current mainframe installations. Sessions at the seminar include: * Putting software costs in context * New pricing models and future costs * Negotiating an IBM ESSO or ELA contract * Maximising the benefit of mainframes * Hardware pricing update The programme covers pricing for all z10 Enterprise and Business Class systems, and also includes discussion of Passport Advantage, Processor Value Units, and their effect on software price/performance.

Re: ICF Catalog performance options
considerations with regard to the following catalog performance options beyond the defaults Eileen McClintock has done a presentation at SHARE about catalog tuning. See if you can find it. She recommended (in 2007), among other things: - Don't use anything larger than 8K CI size; this has adverse index CI effects. - Don't use VSAM freespace, and don't reorganize your catalog; this undoes the benefits of any splits that have already occurred. - Don't let index CI size default; the system almost always selects too small a control interval, which leads to “dead” data control intervals that can't be used in each control area. Allocate your index in cylinders, not tracks. - Shared catalog volumes kill you. Don't have multiple catalogs on the same volume. Don't have catalogs on shared volumes, period. In the latter case every catalog lookup requires a VVR read, regardless of whether the entry has been cached. -- David Andrews A.

SYSCALL is a host command environment you can use to run USS syscall

You need to initialize the SYSCALL environment by beginning a REXX program
with a SYSCALLS('ON') function call. SYSCALLS is a TSO/E external function.
You must distinguish SYSCALL from SYSCALLS!
sleep is a syscall command that invokes the sleep callable service to suspend
(!) the running of the calling thread (task) until the specified number of
seconds has elapsed.
/* REXX */
SUBCOM SYSCALL
say 1st 'SUBCOM SYSCALL' -- RC=RC /* RC=1 */
if SYSCALLS(ON) = 0
then say 'the SYSCALL environment is now established'
else exit
SUBCOM SYSCALL
say 2nd 'SUBCOM SYSCALL' -- RC=RC /*RC=0 */
say TIME()
address SYSCALL 'sleep 15' /* sleep 15 seconds */
say TIME()
call SYSCALLS OFF /* end the SYSCALL environment */

As an aside, it's a little difficult to avoid sharing catalogs between systems these days. :-) My notes were from a presentation she made in 2007. I haven't been to SHARE in awhile, so maybe Eileen has updated it? -- David Andrews A.

Re: Time Parameter
Automation software and loops. Not quite on the topic, but I remember when some Brainiac implemented automated responses to IEF238D and IEF433D. We lost almost 25% of a 400E while Net/Master replied WAIT and then NOHOLD as fast as it could... Yes, waiting is far more efficient. A loop of this type may well be picked up by automation software, with the task being axed as resource hungry. Waiting (SLEEP) allows other work to use the processor in a productive fashion, and is much better for overall though put and service targets. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Of interest to the Independent Contractors on the list
Hi Charles, Right you are. For my senior project (1979), I personally wrote some very non-Y2K compliant COBOL code. It was a major enhancement to a payroll system for a city that was running a Burroughs 1800 at the time. They were so short on memory that everthing else had to be shut down in order to run payroll. Nobody thought about any of the date formats or Y2K at the time and it wouldn't have mattered. The code had to be very lean in order to get it to run on that machine. I'm sure that it was the same way at many other shops too. That payroll system was remediated for Y2K.

Without the efforts of a lot of the people on this list data processing as we know it WOULD have come to an end. You're falling into the that saw doesn't need that safety guard fallacy: That saw doesn't need that safety guard ... no one has cut a finger off in it for years. And yes, states ARE looking to crack down on independent contractors. Easy money in this time of crunch.

Re: Of interest to the Independent Contractors on the list
Hi Linda, Yes, my point was, that it was EXAGGERATED using FEAR for profit purposes. There was no need to upgrade all the Mainframes/Desktops/Servers/Operating systems etc. The place I worked at, spent 16 Million Dollars, on upgrading all the PC's in the Organization and each PC received a Y2K sticker. ( You had to have that Sticker) Note: At home, all my PC's survived the Y2K thing'gie.. Why do a thread always go totally the wrong way on IBM-MAIN... with most of it, just being noise ?

Re: Of interest to the Independent Contractors on the list
How do you know it was EXAGGERATED using FEAR for profit purposes? Exaggerated by whom? Perhaps the executives at your former employer were risk-adverse, or saw senior management's attention to Y2K as a chance to implement worthwhile equipment upgrades. Home PCs are different from corporate PCs. I can live with a lot of oddities on my home PC that would be unproductive on a corporate PC. For example, I am running a lot of unsupported software. I would probably not advise that a corporate IT department do that. Why do a thread always go totally the wrong way on IBM-MAIN... with most of it, just being noise ? I don't know. What did your assertion about Y2K have to do with a thread offering a tax head-up to independent contractors?
