Re: Real storage usage - a quick question
The following message is a courtesy copy of an article that has been posted to bit.listserv.ibm-main,alt.folklore.computers as well. [EMAIL PROTECTED] (Veilleux, Jon L) writes: In z/OS 1.8 the memory management is much more conducive to large memory. They no longer use the least recently used algorithm and no longer check every page. This has made a big difference for us. Under 1.7 we had issues with large real memory sizes due to the constant checking by RSM. This is no longer the case and we have increased our memory dramatically with no performance hit. one of the things found in clock LRU-approximation that i had originally done as undergraduate in the 60s http://www.garlic.com/~lynn/subtopic.html#wsclock was that if the interval between page resets started to exceed some limit, then there was little differention benefit of the reset activity ... least recently used tends to have some implicit dependencies on amount of history ... if the duration is too long ... then it lost much of its correlation being able to differentate between pages as to future page reference pattern. however across a wide range of configurations and workloads in the 70s, clock LRU-approximation had the advantage of effectively being able to (usefully) dynamically adapt the interval. however with a lot of cp67 experimenting and also heavy use of storage reference traces and page replacement modeling ... it was possible to show that outside some useful operating range ... the use of LRU algorithms for differentiating/predicting future page reference behavior became less and less accurate. It was also possible to show that for very large memories ... that the overhead of repeatedly resetting page reference bits provided less benefit than any possible improvement in page replacement strategy. we did do some experimenting at the science center attempting to recognize the operating region/environment across where clock LRU-approximated was beneficial ... and attempt to take some secondary measures/strategies when it was outside that operating region/envrionment. one of the scenarios was that most LRU-approximation algorithms are measured against how well they performed vis-a-vis simulation that exactly implemented least-recently-used page ordering (measured in terms of total page faults for given workload and real storage size). Good approximations tended to come within 5-15 percent (total page faults) of real least-recently-used page ordering. We were able to find some page replacement variations that instead of being 5-15 percent worse/more (total page faults compared to simulated real least-recently-used page ordering), we were able to show 5-15 percent fewer total page faults. the scenario was that in some configuration/workload scenarios, LRU-approximate could effectively cycle thru every page in real storage w/o finding a candidate ... and then take the first page it started with. Besides having a lot of processing overhead, this characteristic effectively degraded to FIFO page replacement (there are operating regions for LRU where it can degenerate to FIFO page replacement at the same time taking an extrodinary amount of processor overhead). our variation tended to recognize when operating in this configuration/workload region and effectively switched to RANDOM page replacement at very low processor overhead (and modeling showed that when not able to make any other differentiation between pages to be replaced ... RANDOM replacement makes better choice than FIFO, independent of the overhead issue). In fact, the original cp67 delivered at the univ. last week jan68, ... also referenced here http://www.garlic.com/~lynn/2007r.html#74 System 360 EBCDIC vs. ASCII ... effectively implemented something that tended to operate as FIFO replacement with purely software and didn't make use of the hardware reference bits. As undergraduate, I did the kernel algorithm and software changes to implement clock LRU-approximation page replacement ... taking advantage of page replacement bits. In this scenario ... with only on the order of 120 real pageable pages ... this reduced the time spent in page replacement selection (under relatively heavy load) from approx. 10 percent of total processor to effectively unmeasureable (and at the same time drastically improvement the quality of the replacement choice). -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Mark, Can I also suggest that you try out my free DDDEFCHK utility that I wrote when I was a sysprog. It uses the SMP/E API to get the list of DDDEFs and then tests for the dataset existance of each. If the DDDEF entry has a VOLUME - it will check that the dataset does indeed exist on the volume. If no VOLUME was specified - the utility returns the volser indicated by the catalog. You can download it from : www.mximvs.com under the DownloadsUtility Programs section. There is also a DDDEFPTH program too that does a similar thing for PATH entries.

If you set your modem to 8 bits you usually lost the parity bit, so you lost what little error checking you had. And a lot of systems still tried to use that high order bit for parity, so you saw a jumbled mess on your PC again. Owners of modem dial-up pools installed workarounds to try to detect what the end user had set, but this was a mess, too. On some systems you wouldn't see anything, so you didn't know what to do. (The correct answer: hit Enter a few times, or maybe Escape, or) I'm sure ATT enjoyed some extra earnings as dial-up modem users had to call over and over again, hoping to get the configuration settings right through trial and error, all because of the complications of 7 versus 8 bits. This affected all sorts of serial connections, including hardwired ones: plotters, ASCII terminals, etc. when cp67 was installed at the univ the last week of jan68, it had terminal support for 1052s and 2741s ... but the univ. had some number of tty/ascii devices. so one of the modifications to cp67 was to add tty/ascii terminal support. the base cp67 code had some stuff for dynamically determining the terminal type and switching the 2702 line scanner using the SAD command. so to remain consistent, i worked out a process to add TTY/ascii terminal support ... preserving the base cp67 dynamic terminal type determination. the univ. also was getting dial-up interface ... with base number that would roll-over to the first unused line. the idea that all terminals could dial in on the same phone number, regardless of type. this almost worked ... but it turned out that they had taken some short cuts with 2702 implementation. the issue was that while SAD command would switch the line scanner ... but the short-cut was that the line-speed oscillator was hard-wired to each port. for hard-wired lines ... the appropriate terminal types was connected to the appropriate 2702 with the corresponding line-speed wired (and then cp67 could dynamically determine the correct terminal type and switch the line scanner as needed with the SAD command). However, this wouldn't work for dial-up lines with common dial-in pool ... where any terminal type might get connected to any 2702 port. so somewhat because of this, the univ. decided to build our own clone controller that would also be able to perform dynamic line-speed determination. this involved reverse engineering the 360/67 multiplexor channel interface and building a channel interface board for an Interdata/3 minicomputer (platform for implemented controller clone). misc. past posts about the clone controller project http://www.garlic.com/~lynn/subtopic.html#360pcm i remember two bugs from the project. one bug involved red-lighting the 360/67. the 360/67 had high-resolution timer that tic'ed at approx 13mseconds. the timer had to update loc. 80 storage when it tic'ed. If the timer tic'ed a 2nd time before the previous tic had been updated in storage (say because some channel/controller had obtained the storage bus for the period and failed to release it for that perioid), the timer would force a red-light/machine check. the other bug was initially getting ascii data into storage .. after running it thru standard ascii-ebcdic translation table, it was all garbage. we eventually figured out every byte was bit-reversed ... i.e. 2702 line-scanner would take leading bit off the line and store it in low-order bit position (in a byte ... reversing the order of bits off the line. the interdata/3 started out doing standard ascii taking leading bit off the line and storing it in the high-order bit in a byte. so initially, the ascii bytes was getting to 360/67 main memory in non-bit-reversed bytes and then being run through the standard 2702 ascii-ebcdic (bit-reversed) translation table. this project got written up as the four of us being instrumental in starting the clone controller business. of course, all the clone controller business was the major motivation for the future system project ... lots of past posts http://www.garlic.com/~lynn/subtopic.html#futuresys including a few with this reference http://www.ecole.org/Crisis_and_change_1995_1.htm from above: IBM tried to react by launching a major project called the 'Future System' (FS) in the early 1970's.

Re: Real storage usage - a quick question
Two things Caution about any case resting on saving CPU by eliminating I/O. Back in the late 1980s a series of IBM studies showed highly variable results in this area. Though the technology has (at least in part) rolled a number of times I'd still take home the same lesson. In z/OS R.8 the cost of memory management got improved because of the RSM rewrite. I'd hazard that any management cost scaled better with memory size... As that was the whole point of the rewrite.

I ran into this in preliminary testing before 1.9 was sent out. I ended up making changes to our SyzSpool spool offload program and our Command processing facility (SyzCmdZ) to get around the problem. It's not an every time type of problem, and the problems (I didn't see any S0C4's) were low impact. I'm sure that the other vendors have also made allowances in their applications as well. I wish IBM had come forward earlier when I reported the problem, but typically vendor complaints don't get the weight that a user gets. At the time we had several clients who were already planning on testing out 1.9 so I couldn't wait for an IBM fix anyway. It turns out that the fix from level 2 does allow me to remove my code, but I'll leave it in place for the time being as it doesn't hurt to have it in and I never liked the idea of telling the customers that they have to apply maintenance to use our products.;) Brian Westerman Syzygy Incorporated -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: System 360 EBCDIC vs. ASCII
OK, more rambling I forgot one other big thing the 360 designers got right: the byte (8-bit characters). I suppose they could have created a 7-bit architecture if it was an ASCII-only hardware design. There was a lot of pressure to reduce the bits to cut costs. The 8-bit byte architecture was the correct decision. It was (is) flexible and easy to extend. There are a few vestiges of 7-bit characters in other computer systems due to ASCII heritage effects, and it's not pretty. Things like uuencoding, xxencoding, and Kermit's 7-bit file transfer are all kludges to try to work around 7-bit architectural restrictions. They weren't fun. I even wrote such a workaround utility (called REXXShip), which translated a binary file into a 64-bit wide character space and wrapped the whole thing in a micro-sized self-executing REXX parser for easy end-user decoding, at least under REXX-equipped OSes. I think the inner content was xxdecode-compatible, so if you didn't have REXX you could use the old fashioned and more inconvenient method. An awful lot of modems and serial connections had to handle 7-bit, too, complicating the user experience for dial-up access to host systems, BBSes, etc. Basically if you set your modem to 7 bits, you struggled to transfer binary files (see: Kermit), and PC extensions for things like line drawing characters looked like a jumbled mess. If you set your modem to 8 bits you usually lost the parity bit, so you lost what little error checking you had. And a lot of systems still tried to use that high order bit for parity, so you saw a jumbled mess on your PC again. Owners of modem dial-up pools installed workarounds to try to detect what the end user had set, but this was a mess, too. On some systems you wouldn't see anything, so you didn't know what to do. (The correct answer: hit Enter a few times, or maybe Escape, or) I'm sure ATT enjoyed some extra earnings as dial-up modem users had to call over and over again, hoping to get the configuration settings right through trial and error, all because of the complications of 7 versus 8 bits. This affected all sorts of serial connections, including hardwired ones: plotters, ASCII terminals, etc. Even parallel printer connections sometimes suffered from 7/8-bit issues. Occasionally you'd buy a cable that worked great with 7-bit ASCII printers, such as a daisywheel printer, only to be frustrated if you tried to move that cable to an 8-bit device like a graphical dot matrix printer. (The manufacturer could save a little money wiring for 7 bits, so some of them cut that corner -- or never tested the 8th bit on their 7-bit test rigs. They got away with it for a while.) This was even more fun if the physical parallel port in the machine didn't actually support the 8th bit. Products like LapLink (which was itself a noble kludge) had to work around 7-bit parallel ports and cables to push 8-bit binary files through, more slowly. There was also the interesting fact that UNIX (and UNIX-like operating systems) and PCs (including Apples) had (and still have) very different ideas about the meaning of carriage return (CR) and line feed (LF) protocols at the end of each line of text. UNIX probably got it wrong, for the sake of economy I guess (LF only). PCs use CR+LF. So with only 128 character slots the OS designers reading the ASCII specification still disagreed about what the codes actually meant for their implementations. And I'm just scratching the surface here. It was so bad that the famous Hayes modem didn't even use decimal 16 (data link escape) or any variation thereof as the signal from the computer to the modem to go into command mode, which would have been a defensible read of how to use ASCII in such situations. Instead, they used +++ followed by a delay (no further character transmission) of about a second as the escape sequence. Then they patented +++ with the delay and were successful in preventing other manufacturers from using +++/delay unless they paid royalties. Whereupon many manufacturers decided to implement +++ without the delay, the best they could do for compatibility, and so there were good times for all (except Hayes owners) as the mere transmission of any +++ sequence, including any non-trivial form of ASCII artwork, resulted (usually) in hanging up the phone as the modem got stuck in command mode. So then the terminal emulation software vendors had to work around that, usually by inserting a software delay between the second and third plus sign. In fact, if you look at any of these historic interchange codes you see vestigal parts that don't have much use any more. That includes almost everything in ASCII below about decimal 32. Anyway, there were some things to like about ASCII (and EBCDIC) and some things not to like. Life was not all wonderful in ASCII land. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z

Re: CSA 'above the bar'
The 2G-4G bar dead zone is for catching programs when they convert to AMODE 64. It has nothing to do with programs that run AMODE 24 or AMODE 31. The point is that an existing program that is AMODE 24 or AMODE 31 might have bit 0 of a 4-byte address on and not have any problem (because that bit is ignored when addressing storage). But when it converts to AMODE 64, that bit would now be part of the effective address (which certainly is not what the program wanted). Thus the system is set up so that a reference, in AMODE 64, to that address will program check.

Re: Real storage usage - a quick question
Here is how I see the answers to the naysayers. 1. The CPU overhead incurred because of the addition of memory blocks would be minimal and you'd probably actually buy back CPU overhead because of things such as less I/O. Adding more memory blocks would allow you to retain more data in memory (DB2 buffers for example) and reduce I/O. In my mind I/O overhead would be a lot more CPU intensive than any memory overhead. 2. Yes, increasing the memory would probably cause the workload to increase slightly. There is always a tit-for-tat situation where you fix one bottleneck in a system another will pop up. However, it sounds like your limiting your CPU usage based on software costs. While I understand the budget thing you also have to decide if you're hurting your customers by doing that. Is your DB2 processing so slow because of the lack of memory that your customers are complaining? 3. So you're paying for 5GB of storage that you aren't using.

Back in the late 1980s a series of IBM studies showed highly variable results in this area. Though the technology has (at least in part) rolled a number of times I'd still take home the same lesson. In z/OS R.8 the cost of memory management got improved because of the RSM rewrite. I'd hazard that any management cost scaled better with memory size... As that was the whole point of the rewrite.

Re: zAAP question
A couple more points: 1. zAAP isn't only for Java any more. The z/OS XML System Services now exploit zAAP. The z/OS XML System Services are available for z/OS 1.7 and higher, and one major user of the z/OS XML System Services is DB2 9 for z/OS, assuming you use DB2's XML features. (This may be reason alone to move to DB2 9 quickly.) IBM has a couple statements of direction indicating there will be more XML exploitation of zAAP in the future, including the z/OS XML Toolkit. 2. The zAAP could influence decisions about how you implement certain functions, yes. But remember that even optimized Java has a longer path length than, say, optimized COBOL. A factor of 10 is not out of the ordinary. Thus I doubt it would be wise to perform non-trivial database joins in Java code versus letting DB2 do the work, for example. But things were a lot more interesting with respect to XML parsing. There are many ways to parse XML, including in Java code (e.g. the Xalan/Xerces libraries for Java). It turns out that XML parsing with Java is one of the most zAAP-eligible workloads. So there were some very weird cases where, for example, XML PARSE in COBOL consumed a lot more CPU (on CPs) than XML parsing in WebSphere (which loves the zAAP, longer path length and all). That probably explains in part why there's a lot of focus on moving other XML processing to zAAP and zIIP. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Real storage usage - a quick question
Esteemed listers I've a problem but I haven't any answer to it or better I've different answers. Say we have a machine with, just to say, 10 Gb of real storage. Only 5 are used by the only LPAR defined (actually there's another very small LPAR, but it's real small), which is a WLC LPAR and often it's CPU capped. 5 Gb remain unused. I asked why, as I'd like to enlarge my bufferpools in DB2 (for instance). I've got these answers: - Increasing real storage increases cpu overhead to managed more memory blocks in a cpu-constrained machine. - Increasing real storage causes more workload so more chanches to hit WLC capping. - It's better to have some spare storage (5 Gb ?). Our workload is increasing and we have some occasional paging spikes. DB2 doesn't perform well due to too small pools. According listers' experience, is using the most part/all real storage (perhaps with a spare memory for future incrases) a real problem ? Did anyone experimented any problem ? What are guidelines ?

I'm tempted to agree about the stack - for the last quarter-century my calculator of choice (and it's right here now) has been a HP41CV. Back then, though, IBM perceived the lack of a stack as a marketing _adantage_. The competition (Burroughs, CDC, ICL) was all stack-based. The previous generations of machine in the UK market that IBM was trying to address - e.g., the KDF9 - were also stack machines.

Re: zAAP question
-Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Tony Harminc Sent: Wednesday, November 07, 2007 10:53 AM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: zAAP question snip Of course there are potential functional and performance problems with this approach, but there may well be financial incentive to do it if the zAAP price is kept artificially low (or if you prefer, the general CP price is kept artificially high). Tony H. Just as a curiousity, was is the cost to acquire a zAAP, zIIP, IFL, CFL, and a general CP? I mean the hardware cost, exclusive of any software costs. One person said, off line, that a zAAP cost them around US $50K. I guess it depends, but I am curious about any ball park figures. I'm still trying, off and on, to convince management that a zAAP and some Java applications (CICS and maybe even batch) might be cost effective. Unfortunately, it appears that management only understands ancient Egyptian for all the good I am accomplishing. I've also mentioned a zIIP if Oracle uses it (don't know) or if we every wake up and use DB2 instead of Oracle. Oracle on z/OS is a good lip service product around here, but we are not doing much of anything. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.

Re: CSA 'above the bar'
snip-- Correct. For an amode24 program, the entire universe ends at address x'00FF'; the next step wraps back to x''. So for an amode24 program, there is nothing above the line or above the bar because for it, there is neither a line nor a bar. That's also my understanding. So, again, why 24-bit programs could be a reason for 2-4G hole ? -unsnip-- Because bit 0 is the switch between 24-bit mode and 31-bit mode, and as such cannot participate in an address. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: CSA 'above the bar'
John, That makes no sense to me... I thought that a 31-bit program could address x'' - 'x'0FFF' below the line, and the same above the line. I.O.W. it could go up to x'8FFF' which means x'0FFF' above ? This means that the hole is from x' 9000' - ?

The origin of this thread was the desire for a CSA in the above the bar area, similar to the CSA below the line and the CSA above the line. I termed the phrase GCSA for this area (G for the 64 bit Grande instructions ). ---unsnip- Huh? I was told that The Bar was the top of the 31-bit addressable space. What did I miss? The bar is actually 2GiB wide, beginning at 64-bit address x'_8000' and ending at 64-bit address x'_'. In the context of this thread, the bar and the hole are one and the same. -jc- -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html Elavon Financial Services Limited Registered in Ireland: Number 418442 Registered Office: Block E, 1st Floor, Cherrywood Business Park, Loughlinstown, Co.
