Re: Please explore CBT Tape File 830 - Xephon MVS articles
hi , is there any a content map for all of this Xephon magazines? On Fri, Aug 20, 2010 at 4:24 PM, Sam Golob sbgo...@cbttape.org wrote: Hi Folks, CBT Tape File 830 contains 926 articles (with their code, as an EBCDIC pds) from Xephon's MVS Update magazines, ranging from July 1987 thru December 1996. The material covered is very wide-ranging, and it is very possible to search for coding examples there. Xephon does not publish their magazines any more, and Thomas publications has given www.cbttape.org the right to support most of the code. So you can now use this code, with the same disclaimer as for the CBT Tape collection itself. (Also see www.cbttape.org/xephon for PDF's of the newer magazines (not just MVS) from 1998 thru 2005). I have already created CBT File 835 out of one of the articles (from Nov 1994), a PPT display program, and I invite you to find what you want, and try to get it working. In the process of doing this myself, I discovered some ASCII to EBCDIC conversion glitches (x'B0' to x'5F') and I have attempted to correct them in the version of CBT File 830 that is on the Updates page of www.cbttape.org. So go to the Updates page of www.cbttape.org to get the source. CBT Version 479 has just been cut, and it now contains 52 updated files, changed from Version 478. I'm looking forward to seeing some results from your explorations of File 830. Please write to me about any observations you make. (Thanks in advance.) And please send in any results to me, if you can, so everybody can benefit from your work. All the best of everything to all of you.

I remember a few years back someone posted on this group that if you thought about 64-bit address spaces it's really absurd: I don't want to be responsible for someone's else opinions! 1. The system could not support enough DASD capacity to fully page-out a single 16 EB address space, and besides the maximum number of page data sets limits you even further He was obviously wrong. 64-bit addressing does not imply full sized adddress space. 2. If you actually did have to page in a 64-bit address space at current data transfer rates it would take around 500 years (or was it 500 hours? my memory is a little hazy on their math; either way it's untenable) As above. Point being your point: one may have theoretical limits and practical limits - which is important? I don't understand. However the above (about 64-bit) shows, that misunderstanding of the real nature of things could lead to false conclusions. Mine conclusions regarding sysplex limits are not false, or at least you did not prove it. I repeat: conclusions about 64-bit addressing are not mine. Does the limit make any sense? Yes, of course: it's MORE THAN YOU NEED. No one will ever need more than 640K 5 mainframes 16 MB Very funny, but again: you cite not mine words.

CPCs - of course having in mind full sized ones, fully dedicated for z/OS. Hint: financial issues do play a role in the game as well. If you know any customer who want more than IBM could deliver, please let us know. Probably some other limitations like # of CF links or former # of timer links can reduce this theoretical limit. These are my words. And this is my point: there are other limitations which can make your calculations irrelevant. And these words are left unresponded! I didn't say anything about 640kB.

Re: DFHSM QUESTION - FINDING LIST OF DSNS
For future reference, you do not need to empty a pack to expand the VTOC. You only need to identify a contiguous block of tracks large enough to hold the new size. If you are able to obtain a list of the datasets that affected by this action, such as by the LIST command already suggested, what do you want to do with it? The answer to this question may lead to effective suggestions using completely different tools.

z196 sysplex question
can z/OS support 80 x 32 = 2560 active CPs per sysplex? No sysplex cares how many CPs an individual system has. If a single z/OS system can have n CPs, and if you can have m of those in a sysplex then by definition you can have n*m CPs in a sysplex. The n*m number is basically content free -- it is likely not a useful indication. how bad was the overhead incurred in managing an 80-way z/OS? I do not have that information. If and when it is relevant to provide that information, I'm sure it will happen. As with any MP situation, it is extremely workload-sensitive. If your 80-way is primarily doing 80 unique things you get one sort of answer. If it ist primarily running 80 tasks of the same server all contending (for example) for a particular lock or ENQ or even a 256-byte line of memory) you get another very different answer.

Re: z196 sysplex question
Radoslaw and Steve, Well, that's a good point. I remember a few years back someone posted on this group that if you thought about 64-bit address spaces it's really absurd: He was obviously wrong. 64-bit addressing does not imply full sized adddress space. [Ron Hawkins] If I remember correctly the post you are referring to was by Chris Craddock, and he usually knows what he is talking about. I think Steve may have placed Chris's post somewhat out of context, and it may be worth re-reading something like that before either of you start tilting at windmills. I have not re-read it, but my recollection seems different to yours. I'm wondering how many there are in our community that are still holding off consolidating their 3380 Ds to Es, keep their LPAR to CP ratio less than 2:1, will never use RAID-5, refuse to put more than 90GB behind a DASD controller, and run channels at less than 30% busy. Once upon a time these were things that were supposed to make MVS shrivel up and die. A 32x80 Sysplex in the near future does not seem so farfetched when I was working on an asymmetric 16 way Sysplex in 2004. All dedicated CEC with up to 10xCP each as I recall and it ran just peachy. IMHO I think it's quite neat how MVS can be made to adapt to what users want to do with it.

Re: LARL vs literal alignment
At 8:40 PM + on 8/21/10, john gilmore wrote about Re: LARL vs literal alignment: Did the literal that originally gave John Baker trouble contain an odd number of hexadecimal digits? No relevant. If you define a X string with an odd number of hex digits it will be right padded so the first digit is a X0 (ie: X12345 is saved as if it were defined as X012345). His problem is that while having an even number of digits it has an odd number of pairs of digits. This caused the literal to be placed after the last HW aligned literal and an odd length literal be HW/Non-HW aligned depending on how many bytes it is past that HW aligned literal (which could be FW or DW aligned since these qualify as HW alignment). -- 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
