Re: Can TSO read Virtual tape using IKJEFT01 to FTP
From: Lizette Koehler To: IBM-MAIN@bama.ua.edu Sent: Tue, February 23, 2010 4:49:31 PM Subject: Re: Can TSO read Virtual tape using IKJEFT01 to FTP In the old days you have the ACCOUNT function in TSO that you could set MOUNT. In today's environment, I think that is controlled in the TSO Segment of your security product. So I would check with your security admins to see if your TSO Segment has MOUNT capability. Lizette SNIP- Ahh the mount authority... we had a terrible time with this and the MSS (3850 for all you newbies). In order to mount a volume tso users had to be given MOUNT the problem with that as I explained to management there is no difference to MVS whether it is a disk mount or a tape mount.. Only a few systems people had it after a big fight and we had to be extra careful a tapemount wasn't requested. This caused no end of confusion to the operators. The other issue was that the MSS was not to fast about mounting volumes and it tied up Q$ for a long time causing others to wait.

Re: Determining if DUMMY allocation
I wasn't picking on JES3 specifically or any one aspect of things. My point
was just that when you are a product vendor you never know what darned
environment your product is going to run in, and it can be *very* difficult
shooting a problem that only happens on a customer machine *without* ticking
off the customer. So I try to choose interfaces -- when they're not GUPI
interfaces -- that in my imperfect judgment (guess?) will be least likely to
cause unpleasant consequences at a customer site. I was just riffing on that
general concept -- not making a real fine judgment -- when I mentioned the
particular bits in question and JES3.
As a smaller vendor you have a particular challenge. I imagine CA does
regression testing on their JES3 box as a regular part of product release.

If you have the JES3 manuals available, and should you have the JES3

It has been a Lonnnggg time since I've done anything related
to JES3 internals. And that was back when we did SYSGENs -- before
MVS/SE.
I don't think that MVS has to be cognizant of JES3 like it use to. So
from this I don't think JES3 mangles the TIOT or SWA. And the DATA AREAS
manual lists IATYDDL ("DD LEVEL INFORMATION") and says that JES3 copies
the data it needs from the TIOT, SWA, etc.
You can check this out along with the JES3 Customization (which lists
the macros and what they do/are for):

Re: Best practice for 24-bit storage in assembler called from C/C++
Thanks all. All things considered, I think I am going to use the "word 0 of the first save area" technique. I will put a pointer to my BTL storage directly there, but I will reserve the first few words for additional pointers just in case a need arises. I will put an eyecatcher on the front, and I will check for 0 in the word before initializing it, and check for my eyecatcher before using the address value. Probably do a single GETMAIN, but make one of the first few words point to the main part of the area so that there is compatibility with a different allocation scheme going forward. CEE3USR and CEEARLU are close runners-up. Looking at them more closely will be my fallback if I get worried about the robustness of the above technique. Thanks again. Great resource.

Rebecca : additional to all the good advice...
It sounds like my situation where SC<->SG and pools were used to keep
one group from clobbering another space-wise ie x37 problems. Now,
everything goes into my STD pool of 80 volumes unless there're very
compelling reasons not to. For me that leaves DB2 - IVP (3 sub-sys),
AppDev (3 sub-sys), and Prod (2 sub-sys), PERM - LnkLst, LpaLst, etc,
Recovery - Logs & backups that are migrated daily, plus a coupla
specialities for under 15 total. (the maximum number allowable for
&SG=) StorClas's are to identify the type of data & service not
where it should be placed. There's no reason they can't occupy the
same SG pool. We also FDR Archive by MgmtClas in all pools.
I used a FiltList to convert obsolete classes (DC, SC, MC) so that it
was not necessary to Alter old entries. Any new dataset creation -
JCL, TSO, IdcAms, recalls, etc. will be automagically transferred to
their new values ie.
FILTLIST OBS_SC_SYSDATA INCLUDE ('MONITOR', 'CICSDATA')
SELECT (&STORCLAS)
WHEN (&OBS_SC_SYSDATA) SET &STORCLAS='SYSDATA'
Keep your old StorGrps around but assign them one fake volume ie.
BOGON00, BOGON01, etc. All StorGrps in the SG ACS should include an
Overflow SG (ie. SET &STORGRP = 'thisGrp' 'SPILL') and I use one for
all my pools. It's make them stick out like a sore thumb. Each pool
should also have a quiesced volume (or several) to allow for that
occasional, really large allocation request. I find the actual size
used is often *much* smaller than SPACE= so I have a daily FDRMove
job that attempts to scour those quiesced volumes and usually finds
space elsewhere in the pool.
I still have a couple of volumes from obsolete SG pools hanging
around in my STD pool (DISNEW) because I haven't bothered to move the
datasets and they're in continual use ie. TcpParms, Ucats, OMVS Home.
It's only been 3 years - I'll find an outage time for them
eventually.
My DBA is also pleased with the new Scratch pool I cooked up. I took
all of the non-assigned volumes and made a pool of them for large,
temporary, gone-in-a-week type uses. (They're sitting empty anyway &
I keep a handful aside for emergency use.) The DBA uses it for
intermediary datasets (a mid-step backup) when he needs to do a whole
bunch of table/index space re-orgs. It's faster than tape and they
default to an MC that deletes them after a while so he doesn't have
to clean-up. When I need to add a volume to a pool, I find an empty
one in the Scratch pool. When my Scratch pool gets small, time to
order new Dasd.
ps. I do my activations mid-afternoon which is a local lull and
always from a different SCDS/ACDS so I can instantly switch back.
After 7+ days, I transfer the IGDSMS10.SCDS into IDGSMS00.SCDS and
activate the permanent copy. Then I can start work on my next
iteration.
pps. DB2 doesn't seem to care what SMS does. I started managing one
sub-system and the DBA's didn't notice for a whole year. They have
approx. 10-20 StoGroups defined but DB2 didn't care if the volume
wasn't what it requested. Naturally, we're not at production yet
with its performance/placement considerations but I think I have a
solution for that worked out.
ppps. ABRInit StorClas= is to get the allocation pointed at the
right SG where the volume resides. After that, it's extraneous
information.

Re: Can TSO read Virtual tape using IKJEFT01 to FTP
In the old days you have the ACCOUNT function in TSO that you could set MOUNT.
In today's environment, I think that is controlled in the TSO Segment of your

So I would check with your security admins to see if your TSO Segment has MOUNT
capability.

Two questions: 1.What do you mean by "independant server C"? 2.What do you mean by "lock out server C"? My guess, if you want server C to initiate the ftp, is to make sure that the dataset under consideration does not exist on server B except in the interval between it being sent by server A and before being gotten by server C. To me, this means that initially the dataset does not exist. Server A then ftp's the data, creating the dataset. Server C will, sometime after that, download the data and delete the file on server B. The above will allow server C to "poll" server B until such time as the dataset appears on B. And then delete the dataset so that it will not redownload the data. Note that if you are talking about a standard z/OS dataset on server B, then server C cannot download it while it is being uploaded by A due to the fact that server B will have it enqueued. If server B is not z/OS (maybe UNIX or even a z/OS UNIX file), then server A will need to ftp an "trigger" file to B once the real dataset is completely sent. Server C must then check to see if the "trigger" file is available. If it is, then download the dataset and delete it and the trigger. Otherwise, wait and try again later. We use this "trigger" method to send data to a Windows server which processes the actual file when the trigger file appears. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.

I know you said you didn't want to keep the DCB open across calls and that may be why you ignored my suggestion. In case you didn't see it, I'll repeat it here: If you are going to keep the DCB open across calls you could: - "extend" your DCB with the rest of your information, i.e. make the DCB the first part of your control block. - when called, run the DEB queue until you find the one that points back to your DCB which you can identify/verify from the rest of your control block. The last time I used this method, and pseudo registers, was in the '70s. It's possible I'm "misremembering" but I think it worked well at the time.

Two questions: 1.What do you mean by "independant server C"? 2.What do you mean by "lock out server C"? My guess, if you want server C to initiate the ftp, is to make sure that the dataset under consideration does not exist on server B except in the interval between it being sent by server A and before being gotten by server C. To me, this means that initially the dataset does not exist. Server A then ftp's the data, creating the dataset. Server C will, sometime after that, download the data and delete the file on server B. The above will allow server C to "poll" server B until such time as the dataset appears on B. And then delete the dataset so that it will not redownload the data. Note that if you are talking about a standard z/OS dataset on server B, then server C cannot download it while it is being uploaded by A due to the fact that server B will have it enqueued. If server B is not z/OS (maybe UNIX or even a z/OS UNIX file), then server A will need to ftp an "trigger" file to B once the real dataset is completely sent. Server C must then check to see if the "trigger" file is available. If it is, then download the dataset and delete it and the trigger. Otherwise, wait and try again later. We use this "trigger" method to send data to a Windows server which processes the actual file when the trigger file appears. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.

Subject: Can TSO read Virtual tape using IKJEFT01 to FTP
I am attempting to do an FTP using IKJEFT01 and getting errors that tape mount
not possible.
I have AUTOTAPEMOUNT set to true.
It works when using pgm=ftp rather than ftping thru batch tso.
My question is, Is it possible for a tso session to read a Virtual Tape? I
have tried
many different ways and googled but not finding what I need. Below is the step
I am executing and below that is the Rexx. This was as close as I could get to
getting the tape to actually mount but then I got abend 1102 ERROR IN FTP, RC
= 27000
basically stating not able to mount tape and autotapemount not used even though
I have
autotapemount set to true in my TCPPARMS member. Any help would be appreciated.
The reason we are using rexx is because ftp fails from time to time and we are
coding the ftp
to be passed a second time when rc not =0. So if you know of another way to
retry that would
help too.

Re: TSO reconnect (ikjefln2) reject by RACF
Dana Thank you for bringing this function, new in V1R11, to my attention. In a sense "fortunately", the title line is somewhat misleading. This looked like something new in VTAM, "support for VTAM ..." and so I decided I should know more about it and did my research. Well, it involves VTAM only as it involves any other program using the VTAM API and it betokens nothing whatsoever *new* in VTAM - that's VTAM as we normally regard it, see later. And while we're discussing what it is *not*, the reference to IP addresses is misleading since the enhancement has no - direct - bearing on TN3270. It's possible however that the customers thumping the table most loudly demanding this function - distinctly in the English rather than the French sense - do so because they want to use it with TN3270 connections. The point is that, without this enhancement - and still if you decide to override the default parameter setting in IKJTSOxx, LOGONHERE(YES), and specify LOGONHERE(NO) - TSO was obliged to have been told that there had been an abnormal termination to the session before TSO would consider a "logon" from a different LU for the same user. With LOGONHERE(YES), TSO is prepared to terminate an existing session for a user when apparently the same user "reappears" using another LU - he/she could not, of course, have been using the same LU and "reappear". IP addresses and TN3270 come into the picture as a practical matter. A TSO user may know that all is lost and that he/she needs to "reappear" but the sedate system may not - yet - have awoken to the fact that all is lost and still consider that a perfectly viable SNA session - although probably not a concatenated TN3270 TCP connection - is still in place. It's interesting that this enhancement - involving nothing new in VTAM, as I said - appears in the Communications Server New Functions Summary manual for V1R11. It absolutely does not belong there and lies through its teeth when it claims to involve "z/OS V1R11 Communications Server". It involves only TSO/E - although I have a niggling suspicion that logic provided by VTAM (the Communications Server SNA component) in support of TSO(/E) may be involved since historically VTAM has had a lot to do with TSO. Do we need to be reminded of that - no we do not, it just confuses us!!! Descriptions of this enhancement appear in the TSO/E Customization manual - only in a section describing how to change LOGONHERE(YES) to LOGONHERE (NO) - a bit superfluous really! - and in the Initialization and Tuning Reference because that's where IKJTSOxx is described - which is all you need to know, especially that it's a function VM has had for eons: Chapter 60. IKJTSOxx (TSO/E commands and programs) ... Statements/parameters for IKJTSOxx LOGON Specifies the system settings for the TSO/E LOGON command: LOGONHERE(ON|OFF) Specifies whether the RECONNECT option on the TSO/E LOGON panel will be honored even when the system does not detect a disconnected state and the user appears to be logged on. This allows users to reconnect their session from a new terminal without canceling their previous session first, similar to how the LOGONHERE option works under z/VM. Default: ON ...

Added to all IBMTCP-L posts: -- For IBMTCP-L subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO IBMTCP-L > ... on a one stack TCP on a 1.9 system. I assume we are talking about the z/OS Communications Server IP component, famous for supporting both TCP and UDP when requested - and even allowing the "transport layer" to be bypassed altogether! If you want to run a variety of applications normally all associated with the same "well-known" port, an alternative to sticking a wet finger in the air and picking a port number at random - and thereby risking a colleague applying some other technique such as the date of his grandma's birthday and happening upon the same number[1] - is to distinguish between the application flavours using the IP address rather than the port used to identify the "server" in the "client-server" relationship. Having noted Hal's contribution where he identifies random port numbers as being anathema to the "firewall boys" as being, I see that this technique which I often promote may well be a way of dealing with this anathema. Assuming you assigned the IP addresses to the same address range as applies to the LAN to which the OSA feature ports which I assume you are using are attached, the "network folk", aka the "firewall boys", won't even know you have put one - or more - over on them! How do you do this? Use a static VIPA if the server never moves or a VIPARANGE type of dynamic VIPA if it does together with either a customisation parameter for the IP address if one exists or the BIND parameter of the PORT statement list entry if such a parameter does not exist. > Does this scenario strike a cord with anyone? But produces a dull thud! Incidentally, if you might have problems with a "firewall", you might like to investigate the tricky topic of running FTP in a mode which makes life easier for the "firewall", "active" or "passive" - I can never remember which without looking it up! It so happens that this technique carries with it several benefits which is too much of a tangent to go into here. If you would like to know more please post again - maybe in the IBMTCP-L list. Just to clarify some rather random references to ports, the "control" conversation in FTP uses the port configured for the server, port 21 if the conventional "well-known" port is used, and an ephemeral port on the side of the client, number N. I suppose that's two. Then the data transfer uses port 20 if the conventional "well-known" port on the side of the server is used with the another ephemeral port on the side of the client, number N+1. That makes another two, which actually adds up to four. That describes "active" behaviour. I could go on, but to check I found URL: http://slacksite.com/other/ftp.html which doesn't need to be copied! This also explains the "firewall"-related "active" and "passive" modes. Chris Mason [1] Of course, if you are being tidy and you have the ear of whoever manages the PORT statement, you insure against the clash by enshrining your random port number in an entry in the PORT statement list along with the selected appropriate typically started task name.

> or using the "word zero of the first save area" solution. I know you said you didn't want to keep the DCB open across calls and that may be why you ignored my suggestion. In case you didn't see it, I'll repeat it here: If you are going to keep the DCB open across calls you could: - "extend" your DCB with the rest of your information, i.e. make the DCB the first part of your control block. - when called, run the DEB queue until you find the one that points back to your DCB which you can identify/verify from the rest of your control block. The last time I used this method, and pseudo registers, was in the '70s. It's possible I'm "misremembering" but I think it worked well at the time.

Charles Had I known which macros you were having problems with, I would not have suggested an ETR. My understanding of the reason for the LIST=NO is because you do not want to list out the CVT or PSA and so on, when you have to include them for a particular macro (executive in this case, as opposed to declarative) to be able to expand correctly. So why have all that cluttering up the listing? Then this way you don't have to know which ones to do a PUSH USING, PRINT GEN, POP USING for (or just PRINT NOGEN, PRINT GEN pair). And every development shop I have worked in has such macros (that are "home grown") that they set the default to LIST=NO because nearly every program uses it, and it doesn't change very often.

I just need one word! My kingdom for a word! I kind of get pseudoregisters I think. The idea is that you can write a bunch of disjoint DSECTs and the compilers and binder will essentially assemble them all into one big area, and tell you at run time the total size (in a CXD) and the offset of each DSECT (in a Q con) within the conglomeration. Coding DXD F is kind of like coding a one-word DSECT -- not wrong but not very efficient use of source code. I guess the fundamental question is this: will something outside of my code give me that one task-unique word? I am beginning to think it will not. The problem pseudo-registers seem to solve is " one GETMAIN for many DSECTs -- even across separate compilation units" -- not "give me some task-unique storage." I keep coming back to the same problem: there's no way anything stored inside your code could possibly be reentrant-task-unique. I think I am down to one of two fairly ugly solutions: passing the storage in from the C++ caller -- made more ugly by the fact that __malloc24() is dysfunctional -- the C code is going to have to get the storage from assembler in order to be able to give it to assembler; or using the "word zero of the first save area" solution. The last time I did a library like this, the calling language was Rexx, and Rexx provides an anchor word that it passes to called routines. That feature makes this problem trivial. Let me repeat a question from the original post: What is CEECAA_TCASRV_USERWORD for? Where is it documented?

Re: TSO reconnect (ikjefln2) reject by RACF
Matan, You should be aware of a few things 1. System Consoles are exempt from OPERCMDS security if they do not log on. This was to ensure that MVS consoles would continue to use native console authorities even when OPERCMDS is active. 2. Started Tasks are never exempt from OPERCMDS security - or any other security when they run "undefined". They have whatever authority any batch job would have - that is, whatever UACC allows. 3. It is always in your best interest to define ALL started tasks to RACF properly. Those listed in the IBM manuals as "TRUSTED" should be defined as trusted to RACF. At z/OS 1.11 (this has not changed in awhile) the following Started Tasks should be trusted: CATALOG DUMPSRV IEEVMPCR IOSAS IXGLOGR JES2 (or JES3) JESXCF LLA NFS RACF RMF RMFGAT SMF TCPIP VLF VTAM XCFAS Optional candidates for the TRUSTED attribute include the following: APSWPROA, APSWPROB, APSWPROC, APSWPROM, or APSWPROT DFHSM DFS GPMSERVE OMVSKERN SMSVSAM 4. Anytime you see an ICH408I message with JOB( ) and STEP( ) - it is a violation that is occurring where the caller has not provided a RACF UserID and is running undefined. In the case of cross-memory checks (as most of the OPERCMDS checks are), JOB and STEP reflect the address space where the violation is occurring - NOT where it came from. So the violation occurred in LLA's address space but may not have been caused by LLA. It is issues like this which necessitate having few if not zero undefined users in your system. If the users run "undefined" you will not be able to determine what is causing the problem - you will only be able to determine which resource is involved. 5. RACF related questions are best asked on the RACF-L.

Even after deducing that this sort of thing was the problem, I had no idea which of *seven* IBM macros was the problem. Tracking down the documentation for each of them (Assembler Services? Advanced Assembler Services? MVS Data Areas? Some of these macros aren't documented at all -- as macros, not the areas they lay out -- are they?) would have burned another bunch of frustrating time.

Yes. 99.235% chance it is a firewall issue. And expect denials from the network folks. For one, you said FTPS, and encrypted traffic is often 'black holed' without a trace or log entry. For another, FTP uses three ports. Depending on your configuration, two of the ports can be unpredictable. Firewall people hate that.

Re: LPARs: More or Less?
George, I don't know that I would say that running QA in a different LPAR than DEV is "best practices", I certainly run them in the same LPAR here, and at nearly every site I have ever worked at. In small shops I typically run a production LPAR, a non-production LPAR (DEV, QA, etc), and a "Sysprog Sandbox" LPAR. As others have said, if you run everything in one LPAR, you are not going to have any process for installing and testing new OS and/or ISP software before going production. This also allows you to control CPU/memory usage at a high level, and prevent non-prod workloads from stealing these resources from production. Larger shops may very well not use LPAR in this way, since they may be able to justify separate CECs for non-production work. As others have mentioned, the point of "isolation" may be more about memory isolation than the points you are making re: SYSRES, PROCLIB, PARMLIB, etc. If the LPARs are for different clients, then I can certainly understand the need for separate LPARs, since an APF authorized program could easily spy into another address space in the same LPAR, but doing that across LPARs is a whole 'nother ball o' wax. All in all, I think your arguments for VM over LPAR are way off-base. Most sites have little or no need for the added capabilities in VM, LPAR does the job very well, and at a significantly lower level of effort and complexity - even if you ignore the addition costs of VM (memory, storage, overhead, and of course acquisition/maintenance). I certainly have no desire to spend time on VM if I don't need the functionality, I simply don't have the time. I have worked on VM before, and rather like it, but if the tool doesn't fit I have no desire to use it. >>> George Henke 2/23/2010 10:56 AM >>> Peace, Shmuel, nol contende. Intelligent people can disagree and still be friends. This whole brainstorming exercise started when my client, who is relatively small, questioned a very specific thing, basically: "Why would I NOT keep QA in the same LPAR with DEV. Why create a new LPAR just for QA and incur $6 million of additional software costs." My knee-jerk reaction, of course, was, "Because everyone is doing it and it is 'best practices'". But it immediately became apparent how ridiculous that logic or lack thereof was. And the more I tried to find a justification, a good reason, for not defying this "best practice", the more I could not find one. And when I could not, I started questioning the merits of having LPARs at all and opened the question here with the hope that someone could. And so far there does not appear to be any. To summarize, thus far it has been argued: *Pro:* z/VM in microcode is more efficient. *Con:* Those efficiencies quickly disappear and are more than offset by the additional CP overhead incurred by the cross LPAR handshaking that must occur for shared I/O. Please see Cheryl Watson's newsletters on this. She points this out and elaborates on it. *Pro:* You can isolate workloads better and give customers and clients better isolation and security. There may also be requirements mandated by law. *Con:* But that isolation is seriously compromised when after creating a separate LPAR, it is all tied back together with shared SYSRES, SYSCAT, PARMLIB, PROCLIB, JESPOOL for support, when "best practices" call for sharing everything at the system level as much as possible? Indeed, one of the vital functions "system symbolics" performs is to allow for this sharing, particularly in PARMLIB. True there are times when there should be a "chinese wall" built around certain sensitive workloads and then LPAR is certainly needed. But these is more often the exception, than the rule. *Pro:* The complexity of knowing both z/VM and z/OS makes it too hard to find people who know both. *Con:* Having installed both in total more than a dozen times myself, the latest being z/VM 5.4 last November, and having known and worked with sooo many others far more knowledgeable than I, not to mention the competition at interview time for both these skill sets, this is simply not true. *Pro:* With LPARs it is possible to take advantage of IBM's "sub-capacity pricing" algorithm and save millions. *Con:* Yes, indeed. IBM's "sub-capacity pricing" algorithm encourages it. But is this necessarilly something we should be encouraged to be doing, ie proliferating z/OS otherwise needlessly, carving up memory, just to take advantage of a favorable pricing algorithm. Are we being led down the primrose path? I like to think that, as a general rule, a software solution will always beat a hardware solution operationally, economically, and financially. But with PR/SM the trend seems to be in the other direction. Such a policy might favor IBM and ISVs, and with IBM's "sub-capacity pricing" algorithm, it might even favor us in the short-run, but in the long-run it is making us more dependent on and constrained by the hardware, not less,

To pick a nit, there is no microcode on a z9 or z10. There is millicode, which is quite unlike microcode. PR/SM is likely more efficient than z/VM because it doesn't do nearly as much.

Wish I had it now, it would go really nicely on Herc. re: http://www.garlic.com/~lynn/2010d.html#79 LPARs: More or Less? the stuff done on csc/vm ... that leaked out to at&t, had been about the same time ... slightly eariler. the design of the shadow page tables followed the semantics for the hardware "look-aside buffer". the virtual machine has page tables that translate virtual addresses to what it thinks are real addresses. However, these are actually virtual addresses for the virtual machine. So when VM runs a virtual machine ... in virtual memory mode ... it is actually run with "shadow page tables". Shadow page table entries start out all invalid. The virtual machine immediately page faults, vm then has to look at the (virtual) page tables (in virtual machine) to translate from the virtual memory address to the virtual machine address ... vm then looks it its page table to translate from the virtual machine address to the real machine address. It is this "real machine address" that is placed into the shadow tables. The early, low & mid range 370s had a single STO stack ... everytime there was a change in the virtual address space pointer ... the hardware lookaside buffer was cleared and all entries invalidated. Early VM370's shadow table operation had similar design, single STO stack, everytime the virtual machine changed virtual address space pointer, all the shadow page table entries were cleared and invalidated. Moving from SVS to MVS significantly aggrevated this ... because MVS was changing virtual address space pointer at the drop of the hat (and vm370 was going thru massive overhead constantly invalidating the shadow page tables everytime MVS reloaded CR1). 370/168 had a 7-entry STO stack. There was a seven entry LRU queue of the most recently used STO values. Each hardware look-aside buffer entry had a 3-bit tag ... it was either one of the 7 currently valid STO entries ... or invalid. MVS constant reloading/changing CR1 was mitigated on real 168 with the 7-entry STO stack (loading new value into CR1 didn't do anything if the value was already one of the seven values in the STO staok). It wasn't until vm370 release 5 with HPO option that vm370 finally shipped something equivalent to multiple STO-stack (i.e. multiple shadow page tables being kept for a single virtual machine ... to try and minimize having to constantly clear all shadow page table entries every time MVS fiddled with CR1). The demise of FS saw a big need to get products back into the 370 product pipeline quickly. 3033 was such effort ... take the 370/168 logic and remap it to slightly faster chips. There was also some activity to introduce some purely MVS microcode performance assists on 3033 ... one such involved cross-memory services. One of the issues with 3033 and cross-memory services ... was the 3033 still had the 370/168 design with 7-entry STO stack ... and cross-memory services was significantly increasing the number of STOs being used ... overrunning the seven entries ... with corresponding big increase in look-aside buffer entry flushing (which netted out to worse performance; somewhat analogous to the shadow page table flushing that VM was constantly being forced to do). -- 42yrs virtualization experience (since Jan68), online at home since Mar1970 -- 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: Best practice for 24-bit storage in assembler called from C/C++
Let me come right out and say I am asking a potentially dumb question here. I freely admit I have never used pseudo-registers or any of the associated features. (Level set: yes, I am totally familiar with the meaning of reentrant and reusable and have coded lots of "do-it-yourself" reentrant code in 360+ assembler.) Why am I asking a dumb question here? Because I don't see much if any overview of the topic in the docs, just detail instruction documentation, and I don't know where else to turn. If anyone could suggest a source for an education in pseudo-registers and related features, I'm all ears. Does DXD help solve this problem? If I code FOO DXD F BAR DC Q(FOO) does that give me a fullword that will be "task-unique" at run time? Will GETMAIN ... LR2,BAR Point to unique storage pointer ST R1,0(,R2) Save my storage area for subsequent use do what the comments say it does? Is this code -- assuming the usual other requirements are met -- satisfy reentrancy? Or am I off base? Environment: Pre-linker, PDS, and "OS" linkage from LE C. Why pre-linker and not binder/PDSE? Two reasons: trying to solve one learning curve at a time, and hoping to avoid PDSEs because of all of the "customer resistance" reasons mentioned in a recent thread on IBMMAIN. (Please don't try to convince me that PDSEs are cool. I have no personal problem with them.

I will cross post this to the TCP List as soon as I re-figure out how to. I have three FTPs running on a one stack TCP on a 1.9 system. Good old FTP 21 is still churning and ftps (open ftp, IBM ported ftp, or whatever it's called) is working and listening on port 22.

The best that I can ascertain, ftps was pushing data and 'suddenly' went into a wait.

The actual separator is generated by the JES code doing the printing. It is not really part of the job itself. And there is, to my knowledge, no /*JOBPARM type control to tell JES to / not to print a separator.

Re: LPARs: More or Less?
Peace, Shmuel, nol contende. Intelligent people can disagree and still be friends. This whole brainstorming exercise started when my client, who is relatively small, questioned a very specific thing, basically: "Why would I NOT keep QA in the same LPAR with DEV. Why create a new LPAR just for QA and incur $6 million of additional software costs." My knee-jerk reaction, of course, was, "Because everyone is doing it and it is 'best practices'". But it immediately became apparent how ridiculous that logic or lack thereof was. And the more I tried to find a justification, a good reason, for not defying this "best practice", the more I could not find one. And when I could not, I started questioning the merits of having LPARs at all and opened the question here with the hope that someone could. And so far there does not appear to be any. To summarize, thus far it has been argued: *Pro:* z/VM in microcode is more efficient. *Con:* Those efficiencies quickly disappear and are more than offset by the additional CP overhead incurred by the cross LPAR handshaking that must occur for shared I/O. Please see Cheryl Watson's newsletters on this. She points this out and elaborates on it. *Pro:* You can isolate workloads better and give customers and clients better isolation and security. There may also be requirements mandated by law. *Con:* But that isolation is seriously compromised when after creating a separate LPAR, it is all tied back together with shared SYSRES, SYSCAT, PARMLIB, PROCLIB, JESPOOL for support, when "best practices" call for sharing everything at the system level as much as possible? Indeed, one of the vital functions "system symbolics" performs is to allow for this sharing, particularly in PARMLIB. True there are times when there should be a "chinese wall" built around certain sensitive workloads and then LPAR is certainly needed. But these is more often the exception, than the rule. *Pro:* The complexity of knowing both z/VM and z/OS makes it too hard to find people who know both. *Con:* Having installed both in total more than a dozen times myself, the latest being z/VM 5.4 last November, and having known and worked with sooo many others far more knowledgeable than I, not to mention the competition at interview time for both these skill sets, this is simply not true. *Pro:* With LPARs it is possible to take advantage of IBM's "sub-capacity pricing" algorithm and save millions. *Con:* Yes, indeed. IBM's "sub-capacity pricing" algorithm encourages it. But is this necessarilly something we should be encouraged to be doing, ie proliferating z/OS otherwise needlessly, carving up memory, just to take advantage of a favorable pricing algorithm. Are we being led down the primrose path? I like to think that, as a general rule, a software solution will always beat a hardware solution operationally, economically, and financially. But with PR/SM the trend seems to be in the other direction. Such a policy might favor IBM and ISVs, and with IBM's "sub-capacity pricing" algorithm, it might even favor us in the short-run, but in the long-run it is making us more dependent on and constrained by the hardware, not less, and so is sub-optimal. It is all somewhat reminiscent of the old MFT days when everything ran in partitions. There were all kinds of inefficiencies introduced when we ran things in fixed partitions then. Certain jobs could not start because they needed a certain amount of memory, devices or system datasets were not available in certain partitions. When MVT came along it removed those constraints and voila, suddenly the floodgates of the CPU and system were open for work and it has remained that way through SVS, MVS, until PR/SM came along. And now we seem to be back into the old MFT partition mode once again all in the name of "best practices". As Marie Antoinette said as she stood before a statute of liberty erected by the guillotine, "Liberty what crimes are committed in thy name" (Mary Baker Eddy) As I said at the start, this is just brainstorming and I do not know the answer, but I do know we can do better than just "LPARs for the sake of LPARs".

Re: Best practice for 24-bit storage in assembler called from C/C++
Charles, Have you looked at the ALL31(OFF) LE option? I don't know how it works for C/C++ but for Cobol this option instructs LE to allocate the COBOL EXTERNAL data in storage below the line. Which means if a main program defines an EXTERNAL variable it will be below the line AND accessible by the name from any subroutine that also defines it as EXTERNAL. This is a rather old trick and so the most current LE may have other options to suit your needs.

Re: TSO reconnect (ikjefln2) reject by RACF
IKJEFLN2 receives control before the address space security environment is fully established. In the non-OPERCMDS world this did not matter as IKJEFLN2 is invoked in supervisor state and can issue the operator command using MGCRE without problems. When OPERCMDS is active, the authority checking requires some sort of identity so that it can verify the callers ability to issue the command. Without the security environment existing, it cannot do this and the failure message you see is the result of that - I believe the "jobname" in the message is just leftovers from previous calls and has nothing to do with the actual IKJEFLN2 invoker. So, to get IKJEFLN2 to successfully issue the operator command with OPERCMDS active, it has to "help" SAF understand the identity of the caller. It does this by building a UTOKEN using the RACROUTE REQUEST=TOKENBLD service and then plugging this into the MGCRE macro service parameters. The UTOKEN formats for each SAF class (eg OPERCMDS) are documented in the RACF manuals and the MGCRE macro in the normal "Auth ASM" manuals.

As a result I had the infuriating situation of having an assembly that was generating an RC=8 but with no error messages in the listing. I was getting more and more frustrated and actually considered taking about 5 system macros and making private copies of them sans the PRINT OFF statements. I had the brighter idea of adding a SYSTERM DD statement and the error message there gave me enough of a clue as to what the problem was and I was able to correct it. Of course it was a user coding error, but then, most assembly errors are user coding errors. If users didn't make coding errors, the assembler wouldn't need any error messages. Meanwhile, an hour wasted on a stupid one-minute-fix coding error. But talk about a "feature" utterly designed to cause frustration - putting PRINT OFF statements in macros and copy members such that error messages disappear. I suppose the justification was obscuring non-GUPI code, but seeing as how it's all browsable in SYS1.MACLIB anyway that seems pretty silly.
