Servicelink again
This weekends outage and I cite: This planned outage will occur because of the installation of IBMlink Release 7.0 which will include functional enhancements to the IBMLink platform and its applications. And the functional enhancement is that now one cannot read apar text anymore! The font has become so small, that numbers are indistinguishable (at least on my screen, no changes to any default settings). That's real nice when you need a ptf number and cannot READ them anymore! In addition, the displays lists severely to the right (on the ETR pages), with even less information per screen plus A LOT more white space showing exactly nothing. Bet you that someone is going to tell me 'this is corporate identity' for my feedback record. They *should have* made sure that their header pages head my preferences for languages. I really hate to have half a screen in German and the rest in English. Choose one or the other, and make that a corporate identity!

Re: Does a DD-Statement waste memory after dealloc?
Clark, If these are for QSAM data sets, does the C program do a FREEPOOL (free the buffer pool) on CLOSE. For reasons I don't understand, apparently CLOSE does not automatically free the buffers. I think the Well, I assume the C-Runtime does a FREEPOOL. If an I/O Error occurs the field __last_op of the __amrc_type can be __QSAM_FREEPOOL.

Re: Servicelink again
Thanks for that feedback, Bob. They must have put, at least, two versions out: one for EMEA and one for the rest. What I see is LARGER font text, a different font type and everything is now centered. Before, it was left-justified on my screen. I logged in with both IE and FF, with the resulting display being identical. Being centered means it has a definite preference for the right hand side, if you see what I mean :-), in comparison to before the change. My colleague (who is using IE8 on a not-centrally-maintained PC) has no problem, either. I, on the other hand, have to use IE6. EMEA Servicelink support has already contacted me; he can see the problem, too. It is only visible for things that come directly from retain. Apparently PMRs don't these days. And yes, we always had a different interface into 'servicelink', even when it was on the green screen. I have also been told by IBM that servicelink will not be maintained indefinitely, and that the strategic product to use is SR. That's why it is so hard to find the servicelink pages and why one always first ends up in SR.

Re: Does a DD-Statement waste memory after dealloc?
Miklos, We are also around dynalloc from C/C++, but You are saying 17000 pages , but the used storage also high ? (RPTSTG(ON)) So is it a reall a memory leak (HEAPC(ON,0,0,20)) or just a high real storage usage ? The LE runtime HEAPOOL(ALIGN) can make big differences . Well, maybe I'm currently a little bit dumb, but where is the difference? When my Prog starts, SDSF reports something around 1700 used pages (ehh, a page is 4K, right?). After some time, it reports (for example today) 15T pages (I assume T=thousand). The prog does a DYNALLOC, OPEN, READ/WRITE, CLOSE, DEALLOC. So somehwere is a memory leak. The last days I tried to find it using different techniques. I used a wrapper around malloc(), calloc(), realloc() and free() to track my own memory allocations. Result: No leak! Nearly everything I allocate gets freed too. I've also used the Heap-Manager CEL4MCHK... again: no leak. So... Until now I can be sure that I've no obvious memory leak in my application. Now I assume something that is special to the z/OS Envoronment makes my application use that much memory (the application runs also on Linux, AIX, SunOS and Windows - no high memory usage is seen on these platforms). Just a few minutes ago I've captured a SVC Dump of my prog - since I've never done things with IPCS this brings me not any further. I'll have to get familar with IPCS first. I also cancelled the prog and generated a dump - the dump has been catched by the IBM Application Fault Analyzer and I'll throw an eye on the analysis later. What I've seen so far is a error message: snip *ERROR* The left node address 1E222AD8 is larger than the parent node address 1E222098 /snip whatever IBM tries to tell me with this left-right stuff ;- I'll consult the manual later Maybe I'm somehow irritating the heap manager Bye, Michael -- Yours sincerely Michael Knigge Development S.E.T.

Re: Does a DD-Statement waste memory after dealloc?
Michael, I remember some years ago I wrote an assembler-routine doing OPEN/GET/CLOSE some hundred times a day. After some weeks the routine terminated with 878 and the dump was full of wasted storage-entries all heaving the same length (I do not remember details). The solution was to code the FREEPOOL-Makro. Explanation: The FREEPOOL macro releases an area of storage, previously acquired for a buffer pool for a specified data control block. The area must have been acquired either automatically (except when dynamic buffer control is used) or by executing a GETPOOL macro. For queued access methods, you must issue a CLOSE macro for all the data control blocks using the buffer pool before issuing the FREEPOOL macro. For basic access methods, you can issue the FREEPOOL macro when the buffers are no longer required. A buffer pool need be released only once, regardless of the number of data control blocks sharing the buffer pool. SC26-7408-02 I think this hasn't changed yet. It was an assembler-routine but other languages will internally do the same and if IBM uses the same routines for OPEN/GET/CLOSE it will be the same result .. remaining storage. Maybe that's the reason why you only see it on IBM-Systems Juergen -- 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: Does a DD-Statement waste memory after dealloc?
A few suggestions for looking at the dump with IPCS. Under the COMMAND panel, try VERBX VSMDATA 'SUMMARY' Then go to the end and there is a nice summary. Find the subpool where most of your storage is used, then go back in the listing and find repetitive sizes in that subpool, then go into the view panel and look at some of those areas. That will generally tell you if it is you because you recognize the data, or maybe there is an eyecatcher in the memory. The other thing I find interesting is the fact that you are up to 17T real pages. Either some program is looking at a lot of storage all the time, or that storage has been pagefixed. If it was not pagefixed, the system probably would have paged some of that storage out. To see what is pagefixed you can run a RSMDATA report.

With 20-20 hindsight, all computers should have started off marking files that way. It's not easy changing, but it would really be worth it. Regrettably, it rarely works right. MVS and UNIX early realized the benefit of UTC (but MVS only partly -- how are ISPF PDS members marked? What about tape labels?) But new systems must reinvent. MS DOS and Macintosh OS both well after started running the primary clock on civil time. Mac is better now; Windows is still ailing. I suspect the mechanism is that engineers eager to get to power-on test start their test beds with the clock on civil time. They procrastinate implementing the conversion routine. Then the shipment deadline looms, and the transition is deferred to a future release, then the conversion effort is unacceptable. (When will ISPF start using UTC?) And z/OS and Unix System Services still don't do it right for US timestamps prior to 2007. What fraction of z/OS installations (away from the UK meridian) still run the [E]TOD on civil time? Especially for those sites that gradually change the time to make sure transactions get stored in order as the clock bumps back because of daylight savings time - but also for any multi-time zone database. Gulp! And the ETR will only slew a couple seconds a day. It wouldn't finish before time to change back. I understand that during leap seconds, z/OS dispatches no jobs.

CKD multi-track search introduced with original 360 was scarce resource use trade-off of the period ... by the mid-70s, the relative amounts of resources had nearly inverted (which resources were the scarcest), starting to make multi-track search the exact wrong thing to do, there was a large national retail operation with a consolidated datacenter (large number of systems in loosely-coupled configuration) ... which started to run into severe throughput problem during peak periods. This went on for awhile, lots of experts being brought in over period of time, until they eventualy got around to calling me in. I was brought into a class room with large number of long class tables ... covered with high stacks of paper performance details from all the systems. while i started to leaf through all the pages (for shared disk activity, I had to aggregate drive activity from different systems/reports in my head ... while they started through overall summary of the symptoms). After about 20-25 minutes ... I started to notice a somewhat anomolous circumstance ... about the only correlation between good thruput and nearly no thruput was a specific pack had aggregated i/o counts between 6 and 7 during high-load/low-throughput (which would seem to hardly be a thruput limitation). After a little more investigation ... it turned out, the pack contained the shared application library for the whole complex ... more investigation was that the PDS had a three cylinder PDS directory. Back of the envelope calculations was that avg. depth of search was cylinder and half (PDS member lookup) ... that would be two multi-track search I/Os that took elapsed time of nearly 1/2 second. Assumption then was the two PDS directory lookup I/Os would be followed by a single I/O for a PDS member load. That accounts for aggregate of six I/Os per second saturating the drive ... basically limiting the whole national loosely-coupled infrastructure to performing an aggregate of two application (PDS) program library loads per second. Each full-cylinder multi-track search represented enormous busy elapsed time for the processor channel (locking out any other activity on the same channel). The full-cylinder multi-track searches also locked up the (shared) controller, string and drive ... locking out all systems from accessing anything else associated with those resources. The eventual result was reconfiguring everything to try and come as close as possible to eliminating the long multi-track searches (drastically reduced PDS directory size) ... and replicating the shared application library on non-shared drives for each system. PDS directory ( vtoc) multi-track searches alleviated needing the real storage to contain the directory information (at enormous cost in I/O resources). By the mid-70s, real storage was becoming plentiful enough that it was practical to keep high-useage (vtoc ) PDS directory information cached in system storage (allowing fast lookup of instorage index) ... so program loads could happen at normal disk activity thruput speeds (say 30-50/second) ... instead of at 2/second (limited by the enormous PDS directory multi-track search penalty). This resource trade-off also showed up with RDBMS ... the original relational/sql was done on vm system in bldg. 28 ... system/r ... misc. past posts: http://www.garlic.com/~lynn/subtopic.html#systemr In the 70s, there was somewhat rivalry between the IMS group in STL and system/r in bldg. 28 on the main plant site. IMS group claimed better trade-offs because record pointers were exposed as part of the data ... and it was possible to go directly to a specific piece of data. This was contrasted with RDBMS implementation that had an implicit index ... which could take 4-5 disk i/os to eventually find the location of the desired data record. This implicit index also tended to double the physical disk space required (vis-a-vis same data in IMS). The system/r group countered that the exposed record pointers created a significant administrative and maintanance overhead ... especially for adding data ... nearly eliminated by the implicit indexes). The resource trade-offs argument changed with combination of enormous disk size increases and drastic fall in cost/mbyte (muting the issue regarding doubling disk space for the indexes). At the same time there was significant increase in available system real storage ... making it practical to cache a large portion of the (implicit) RDBMS indexes (drastically reducing separate physical disk i/os to find data record). -- 40+yrs
Re: Does a DD-Statement waste memory after dealloc?
Hi Juergen, The FREEPOOL macro releases an area of storage, previously acquired for a buffer pool for a specified data control block. The area must have been acquired either automatically (except when dynamic buffer control is used) or The problem is, that FREEPOOL needs the DCB - an because my appl is written in C, I don't have any clue about the DCB Bye, Michael -- Yours sincerely Michael Knigge Development S.E.T.

Re: Does a DD-Statement waste memory after dealloc?
Hi Chris, Under the COMMAND panel, try VERBX VSMDATA 'SUMMARY' Thank you for the hint... I tried it and what I get at the end of the summary is: VSM SUBPOOL TRANSLATION TABLE ERROR DETECTED The other thing I find interesting is the fact that you are up to 17T real pages. Either some program is looking at a lot of storage all the time, or that storage has been pagefixed. If it was not pagefixed, the system probably would have paged some of that storage out. To see what is pagefixed you can run a RSMDATA report. gives me BLS18100I ASID(X'0001') FFB744 not available for PVT IAR80303I Primary RSM data area not in dump. RSM processing terminated. Well all this stuff is somehow wired... Using IPCS I was able to see that I use most of the space in the extended user region (ELOAL = 3A4F000) and with the IBM Fault Analyzer I was able to see that there are many many modules loaded in this region that I've never heard about :( So I'm out of the office now for two days and when I'm back I guess I have to study a lot of manuals (i. e. ABCs of SysProg and so on) to get familar with all this stuff... I ask myself why there is no how to find memory leaks guideline in the ABCs of System Programming Manuals... Other stuff is handled (for ex. loop detection) So far, thank you for your hints bye, Michael -- Yours sincerely Michael Knigge Development S.E.T.

Re: Secret Service plans IT reboot
Is that even possible for 1980 era hardware? How long has it been since the last spare parts were made? Do we even know that it is one of the water machines? Maybe it is a 4381 - those things might run forever. In any case, I would *really* like to know where this machine ends up. The old water cooled machines are nearly extinct. -- Will -- 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

One of the classic SHAREs the 'Fat Boys' actually were brave enough to document their experiences when converting to a 43xx(maybe a 61 don't remember).

Re: SCLM and ++include statements
Scott: These Are a Panvalet product only. This a possible way to handle them. Use your global editor to find (and replace) ++INCLUDE to copy ... This works some of the time. The issue is that IIRC the member name may be up to 10 characters which probably does not fit in most PDS's. I think what we did we found all the ++ includes and sat down with a person from the group and renamed all e members to 8 chanacters and used PAN to export the to the desired members. This was a nice project for a junior person to do and the person from the team gave input. The project had its bumps but it worked 99 percent of the time. Panvalet was OK for its day, I guess. I do remember them charging a pretty buck for the ISPF interface. We bought it but at the point we were also getting geared up to drop the product.
