An USS Question
I have received a private e-mail with a question which ought to be asked in the list, the reasons being 1. A question and answer in the archives potentially helps anyone 2. We who generally answer questions do *not* participate in the list in order to be identified as consultants for private work - if indeed private work without recompense can be described as work rather than charity which, for business, is surely an oxymoron! The question was as follows: We have got a new test environment built, and I need to add the option on the logon screen. Where do I have to check to find out? Do I have to edit the USSTAB or Modetab?? I will now address the original poster. Irfan As so very often, I need to try to extract what is really being talked about from approximate terminology. I assume, particularly since the USSTAB is mentioned later, that logon screen refers to USS message 10. I also have to assume that option refers to the possibility to enter a token which USS processing in VTAM will cause logon to an application, possibly with some text in the USS message 10 that this token can be entered. Indeed, this involves customisation of the USS table - and *not* generally the mode table.[1] I can also guess that the installation already has an USS table which has been set up by someone who has been let go without having left adequate documentation over the USS table customisation and cannot now be contacted. Since the USS table needs to be assembled and linkage edited ideally into a VTAMLIB data partitioned data set concatenated with the supplied VTAMLIB partitioned data set, it is first necessary to find the source of the existing USS table. In order that I could always find it along with encouragement to students to do the same, I always put the USS table source - along with the mode table source (and interpret table when it had a role worth mentioning) - in the VTAMLST partitioned data set - although it was of no use to VTAM there. At the customer where I work from time to time, the source of these VTAM tables was *not* stored in the VTAMLST partitioned data set and it was a magnifying glass job to try to find one of them in amongst a range of possible source partitioned data sets, always hoping that, when found, it was the version of the source corresponding to the load module. This could actually be confirmed - by and large - by eyeballing the hexadecimal of the load module with the source statements! Once you have found the source, you can introduce the changes. It may be that the source helps you because an exiting sequence of USSCMD and USSPARM statements shows you how to set up a new set and actually understanding precisely how it is done can be postponed. However if you need actually to understand what you are doing, the relevant reading can be found in the z/OS Communications Server (CS) SNA Resource Definition Reference manual under Unformatted system services tables in Chapter 5, User- defined tables and data filter. In case you do refer to the manual and, as seems likely, it is the first time looking into this topic, be aware that you are working with a Session-level table and you can ignore all the distractions which concern Operation-level tables. I almost forgot that you may want to add text to the USS message 10. Again, the existing USS message 10 text may be sufficient of a guide. If the text is SNA Character String (SCS) (corresponding to SSCPFM=USSSCS), then this is relatively easy. If the text is 3270 data stream (corresponding to SSCPFM=USS3275 probably rather than SSCPFM=USS3270), then you may need to become an instant specialist in 3270 data stream programming - in other words, it can be a bit more complicated! If you need more help, please post again as a reply to this post rather than privately and say whether your USS table is for use with CS SNA (VTAM) or CS IP TN3270. If the latter then what I said earlier concerning VTAMLIB actually concerns a load module partitioned data set associated with your TN3270 server application. Chris Mason [1] Because it is possible to enter a mode name as part of the character string used in order to log onto an application, it is possible to create mode table entries with perhaps more user-friendly names as part of the process of setting up user-friendly logons. Long ago, before the days of what I used to teach as the unspecified screen size BIND, this was indeed a likely part of USS design - or should have been. These days, there is much less call to bother about setting up mode table entry names along with USS customisation. -- 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: COUPLE DATA SET TIME STAMPS
We also have LOGR and WLM CDS data sets, and making new versions of these is not so easy. Can anyone reliably advise whether the LOGR and WLM data sets have the same sort of time checks as the XCF ones do, or can we expect them to happily accommodate the clock going backwards. You may run into problems with the LOGR CDS. Check out II5 if that applies to you. IIRC, the problem was going forward in time for LOGR. If there are WLM problems, it is fairly easy to unload the current WLM policy, come up after IPL with an empty, freshly formatted WLM CDS, and then 'load' the policy into it from your saved copy. There may even be a programmatic interface to do that so you don't need to come up with an empty WLM CDS.

IBM Defaults (spinoff from FTP to z/OS Problem)
... and the IBM defaults are assumed to be right until they are proven wrong; right? is a line taken for the thread FTP to z/OS Problem which I think deserves wide airing. I always used to tell my students - principally when teaching SNA topics and products such as VTAM - that defaults always work (nearly always[1]) but probably give the worst performance. The reason I made that statement is in order to justify taking up the students' time with explaining mechanisms such as pacing and why it makes sense either to eliminate pacing altogether - for self-paced (through definite responses) 3270 data stream traffic for example - or take the trouble to set a higher value than the restrictive default of 1 or 2. But there are other defaults. The developers would never say it - publically - but there can be times when a design is improved where the default specification of often a new parameter is the bad old way. Thus the recommendation is not to accept the default but always to specify the parameter so that the improvement can be employed. OSA behaviour was vastly improved by doing what should have been done in the first place. When an OSA feature port is shared, the bad old way was to have to check every packet against a destination IP address list in order to know to which OSA feature port user to pass the packet, The good new way is to use a different MAC address for each user so that the destination is evident without needing to check against the list of IP addresses. All this is a bit of a no-brainer when it comes to deciding which is better. However, if you don't add the VMAC parameter explicitly, you're stuck with the bad old way. Sometimes the developers are a bit sneaky and slip in an improvement - and - change the default so that the improvement is used - with crossed fingers that the law of unintended consequences, aka Murphy, is not looking! One case of this is the VTAM start option PSWEIGHT. When the LESSTHAN option was introduced it was made the default. According to the usual IBM principle, it should have been EQUAL (as opposed to SAMEROUT) as it was before. Sometimes developers can try to sneak in a supposed enhancement without providing an option not to use it and, in principle, setting the default option not to use it. Such an enhancement was the VTAM APPL statement FASTPASS operand, to which reference can only be made using the operand name *because* providing an operand was imposed upon the VTAM developers and an APAR was scrambled out. The idea was that it was unnecessary to start a session when logging on to an application such as TSO before immediately ending the session and setting up another session. All very sensible until it was discovered too late not to cause massive disruption that NetView Access Services depended on the old method. NetView Access Services had some checking logic that was incompatible with the change. Murphy had a terrific day when that decision was made! Note however that the default for FASTPASS is YES and the improved pattern of session setup is selected by default.

I also suspect that the (FTPSDATA) for the server should be SEZAINST (FTPSDATA) for the server. You need to acquaint yourself with the whole Understanding search orders of configuration information and some following sections in Chapter 2, IP configuration overview, if not the whole of the chapter. I suspect that nearly all of your questions are answered there. Well, barely customised. The resolver is considered customised if you change the SYS1.PARMLIB BPXPRMxx RESOLVER_PROC statement from RESOLVER_PROC(DEFAULT) to RESOLVER_PROC(something) where something is typically RESOLVER. You will then necessarily create a RESOLVER procedure and typically add a SETUP DD- statement which needs to refer to something. Having gone to this much trouble, it is then usual to consider how one might benefit from all this toil and sweat! ... and the IBM defaults are assumed to be right until they are proven wrong; right? This is such an interesting topic I have created a separate thread in order to attract comments from at least the usual suspects. Note that the DATASETPREFIX value is not used as the high-level qualifier of the data set name used as the last step in the search order for the PROFILE.TCPIP and TCPIP.DATA configuration files. That last bit is certainly of interest. The what does this mean: quote PROFILE.TCPIP search order The search order for accessing PROFILE.TCPIP information is as follows. The first file found in the search order is used. 1. //PROFILE DD statement 2. job_name.node_name.TCPIP 3. hlq.node_name.TCPIP 4. job_name.PROFILE.TCPIP 5. hlq.PROFILE.TCPIP /quote In this case where does HLQ come from? I thought this was a good question and it sort-of is. Our dear friends the manual authors have made a mess yet again. Having spent quite a while checking this out, I now think we have a failure fully to update the manuals when it was decided to hardcode that last step in the search order. Note that, if you have decided on using the PROFILE DD-statement all of this complicated discussion regarding hlq and node-name is moot and is, frankly, best left buried in the detritus of past and gratefully long-forgotten manifestations of TCP/IP for MVS/the z/OS Communications Server IP component. The PROFILE data set search order is defined twice in the Configurations Guide and twice in the Configuration Reference. Although not at all democratic, since it is a minority of three to one, I believe the most correct version of the four is the following taken from PROFILE.TCPIP search order in Configuration files for the TCP/IP stack, just after the famous Table 3 which contains the version you quoted in fact, in Chapter 2, IP configuration overview in the Configuration Guide: quote - //PROFILE DD DSN=aaa.bbb.ccc(anyname) - jobname.nodename.TCPIP - hlq.nodename.TCPIP - jobname.PROFILE.TCPIP - TCPIP.PROFILE.TCPIP /quote The version you quoted can be found in the famous Table 3 in the Configuration Guide and twice in the Configuration Reference. I suspect, as usual, that the manual authors just forgot - a change of shift with no collective memory - that there was more than one version of this search order provided in the manual. In the beginning - or as far back as I can vaguely remember - TCP/IP for MVS was hardcoded with an hlq of TCPIP. There was an SMP USERMOD-style job that could be run in order to change this. The circumstances of my teaching systems was that they were copies of a production system that was post-SMP and so I could not run this SMP job. Instead I set up a massive SUPERZAP job which changed the upper teens number of instances where I was able to identify TCPIP in the load modules - just to show that the hlq could be changed. Then along came DATASETPREFIX and the hlq problem was largely solved. Probably at about the same time to the very many dynamically allocated data sets was
USSTAB Message Corruption Revisited
Last August I worked with Chris Mason on a USS table issue. A brief recap: TCPIP provides symbol substitution in USS messages which contain system symbols and certain defined character strings that start with two or more '@' characters. VTAM also provides symbol substitution for defined character strings, but not for system symbols. With 3270 data stream formats, certain control characters can be mistaken for the ampersand and at-sign characters. Set buffer address (SBA), erase unprotected to address (EUA), Repeat to address (RA) and start field (SF) can potentially cause this problem. I ran a number of tests on my sandbox, and demonstrated that, for example, a SBA for row 14 column 1 on a 80-character wide screen results in a hex address of '5050', which is a double ampersand. If this were followed by the characters 'SYSNAME IS TESTXYZ', and the system name were 'TST1', then the SBA field would be corrupted with the second x'50' being replaced with x'E3' followed by the characters 'ST1'. The resulting display would put 'ST1 IS TESTXYZ' at row 14, column 20. I saw that as a problem. I opened a problem with IBM back then, and after a long, slow process, I managed to convince them that this is not how the function should work. This month I got a usermod to test. It did not address this specific problem. All it addressed was the truncation of data. In the example above, the text is actually shortened to match the length of the substituted value, which can adversely affect alignment on a formatted screen, even when the substitution was intended by the programmer. The second part of the fix was to update the documentation so that the handling of system symbols and TCPIP variables is more specific. System variables are ALWAYS replaced in the TCPIP environment and other TCPIP variables are only replaced when requested by a parameter on the USSMSG macro, but that's not how the documentation reads without the changes. No attempt was made to address unexpected variable substitution, and I have had to open a second new problem to initiate a requirement. The requirement is that the code should work as expected and not astonish the programmer with unexpected results. For our environment I use macros to generate 3270 control codes, and I wrote a program that reads a generated USS table to display the message 10, so I can verify that it appears as expected. It's great for testing, but when TCPIP might randomly alter the data after I implement in production, it can get really frustrating. In summary, you can expect the documentation changes within a few years, and you might see a PTF or two some day as well. In the meantime, if you think something might be wrong with your USS tables, call IBM. They would be happy to walk you through the process of checking every SBA, EUA, RA and SF for special characters and help you build a work-around. -- 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: IEBCOPY losing APF authorisation in middle of JOB - etc
Ok, I am puzzled. Whether there is or is not an I/O appendage routine hidden away inside of dear old IEBCOPY seems immaterial. APF authorization is not something that just comes and goes within a step. Every new step can be authorized or not, but if the JOBLIB, STEPLIB or application specific library concatenations are the same for each step in the job, the system is going to get the same answer each time. There's just no such thing as losing APF authorization. For any new job step the system checks the AC attribute of the incoming job step program. If that's AC(1) then the system checks that the load library is APF authorized. If it IS then the job step is given control in an APF Authorized condition (i.e. JSCBAUTH=1) otherwise it is given control completely non-authorized. Now there are some gotchas of course. The one that trips up most young players is that for a load library to be considered APF authorized, EVERY dataset in the concatenation must be APF authorized. So even if you're fetching IEBCOPY from a righteously APF authorized library, if you have that library concatenated (e.g. in a JOBLIB or STEPLIB DD) with a non-authorized library then the entire concatenation is considered non-authorized and IEBCOPY won't run authorized. So assuming IEBCOPY is doing the right thing (FSVO the right thing) on some steps and not others, I'd be looking for a difference in libraries between those steps. -- This email might be from the artist formerly known as CC (or not) You be the judge. -- 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

If there is no z/OS-supplied cleanup of ACEE, then your RESMGR could perform the VERIFYX ENVIR=DELETE - in fact this is probably a good idea anyway. Another job for the RESMGR could be to cut a sign-off SMF record (and you could cut a sign-on when you perform the VERIFYX ENVIR=CREATE). Really getting complicated! If you go down the START command route and your method of assigning ownership to the created address space is a parameter on the START command - what is to stop any bozo who has opercmd authority from spoofing a userid on to one of your address spaces ? Not a parm on the START command. The listener will establish a TCP connection to the client. After it does the START, the listener would do a GIVESOCKET. The started task would then do a TAKESOCKET. The desktop client would then send the RACF id / password over the socket. The started task would then use BPX1SEC or IRRSIA00 to logon using the supplied userid/password. If this works (good user/password), the STC sends a message to the client that the connection is complete. The client on the desktop then daemonizes itself to detach from the shell, retaining the socket to the STC. This daemon is then used as a relay for other commands in order to talk to the z/OS STC. But, now that I think about what happens in CICS, if I don't do the equivalent of a ENVIR=DELETE before terminating the STC, I won't get the RACF SMF record that I would like. rats/ There is something that makes me uneasy about an address space that spawns other address spaces in the fashion that you describe - maybe I am concerned about ASVT slot shortages if the spawn process gets into trouble or any x-memory coding errors that could mark these ASIDs as non-reusable. The started task(s) involved do not use x-memory coding. They don't talk to each other after the START is done at all. They are totally independant.

Re: DFHSM QUESTION - MOVING TO DASD FROM TAPE - ML2
Darth, We're looking at doing the exact same thing as Esmie. As to your asking why, here is our reasoning. All we have left on the 3590s is DFHSM processing. We have moved our system backups to TS1120 media, but don't want to use the same library for DFHSM as our backups. If we can move the HSM ML2 to disk, we can eliminate the hard costs of maintaining the 3590s, reclaim the floor space, eliminate the operator intervention for doing recalls, tape recycles, and all that fun stuff. As far as why we're looking at leaving ML1/ML2, we have just migrated all our production data (including ML1) from one disk array to another. My plan is to take the older array (still quite servicable and usable DS6800), reconfigure it as all MOD 54 devices, and move my ML2 to this array. I can then back these MOD 54 devices up to tape for offsite, and the ML2 is on a different array from my production and ML1 devices. My ML1 is a lot more dynamic than my ML2, so I can't see using the MOD 54 devices for ML1 due to the VTOC size. (I don't have PAV).

Re: DFHSM QUESTION - MOVING TO DASD FROM TAPE - ML2
Darth, The ML1 and ML2 are usually cheaper and lower performance than Primary Storage. ML1 cost efficiency is usually achieved through compression, whereas ML2 is a change in media. ML2 Tape can easily be replaced with Tier 2 disk using internal SATA, external virtualized midrange storage, or earlier generations of DASD disk systems with a reduced maintenance cost (I think Radoslaw did this with 7700E). Ron If I understand this correctly, you're going to have 2 levels of migration both on Disk? Even if that's possible, what does it gain you? Wouldn't it make more sense to just have an ML1 and then no ML2? And again, I question whether that's even possible with HSM. I do seem to remember this same discussion in the past, so you should probably check out the archives. We're actually going the other route - we're moving to a 'tapeless' virtual tape system I'm eliminating ML1. ddk -- 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

My first job as a coop student at IBM was to convert a 650 SOAP program that ran the Toronto plant to a 1401 card system Autocoder program. I think I still have the card systems Autocoder compiler decks somewhere. I did read the SOAP program to figure out what the program did, but never wrote any 650 code myself. Not a fond memory, but an interesting one. The 650 we were taking out had a 2 (4?) KB drum memory. The autocoder (think BAL) program I wrote to replace it was for a 4 KB 1401 card system. High/Low/Equal compare was a special feature on a 1401. Tom Russell IBM 650 drum memory was in 40 tracks or 50 words, containing decimal digits, not Bytes. Total capacity was 2000 words, with each word an instruction or data, 10 decimal digits plus sign, each digit represented by bi-quinary encoding (7 bits). It could be thought of as roughly equivalent to 20K decimal digits or 10K characters. Around 1961-1962 as a high school student in Norman, OK, I read the IBM 650 manuals and wrote some simple code examples for the 650 at O.U.; but it was an expensive and temperamental beast with no free time, so I was steered toward a new IBM 1620 that had much idle time, and learned to do my first real programming on that machine. The IBM 650 was replaced not that long after with an IBM 1410. I can still recall people discussing research that was negatively impacted by the need to re-write application code whenever a new machine was acquired. -- Joel C.

Re: 45 years of Mainframe
I wrote the mainframe history presentation originally to present to the University of Waterloo computer science club about 10 years ago. I have been updating it ever since and I have two versions now (one general and one with additional VM information). I used it at a special session at SHARE in Boston for the 50th anniversary of SHARE and did another major update for the 45th anniversary of S/360 last year. I have not been around IBM quite as long as Tom (only 37 years for me) but our team here in Toronto has a lot of long-serving mainframers. My first computer was an IBM S/360-75 (remote via cards at the North York ON school board) and an IBM 1130 at my high school in Don Mills ON (near the then IBM plant and lab, we were spoiled by IBM). This was back in 1969/1970. When I went to college it was a step back to accounting machines (yes, a 407 and a 514) then to a 1620 and finally a S/360-30. My first job as a co-op was a further step back to a 650 at Defense Research in Victoria, BC. When I joined IBM in 1973 it was to work as an operator on a S/360-20 and a S/360-67. -- 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: IEBCOPY losing APF authorisation in middle of JOB - etc
Yes to all of that Puzzled me too ... Never seen it before I am aware of the concatenation restriction on APF authorised load libraries (and the integrity reasoning behind it), but there are no steplibs in the job and the Joblib is, obviously, the same for all steps. I will chase it up with our sysprogs today, and see if they have found out anymore. PDSMAN does seem to be the main suspect here though.

Whether there is or is not an I/O appendage routine hidden away inside of dear old IEBCOPY seems immaterial. APF authorization is not something that just comes and goes within a step. Every new step can be authorized or not, but if the JOBLIB, STEPLIB or application specific library concatenations are the same for each step in the job, the system is going to get the same answer each time. There's just no such thing as losing APF authorization. For any new job step the system checks the AC attribute of the incoming job step program. If that's AC(1) then the system checks that the load library is APF authorized. If it IS then the job step is given control in an APF Authorized condition (i.e. JSCBAUTH=1) otherwise it is given control completely non-authorized. Now there are some gotchas of course. The one that trips up most young players is that for a load library to be considered APF authorized, EVERY dataset in the concatenation must be APF authorized. So even if you're fetching IEBCOPY from a righteously APF authorized library, if you have that library concatenated (e.g. in a JOBLIB or STEPLIB DD) with a non-authorized library then the entire concatenation is considered non-authorized and IEBCOPY won't run authorized. So assuming IEBCOPY is doing the right thing (FSVO the right thing) on some steps and not others, I'd be looking for a difference in libraries between those steps. -- This email might be from the artist formerly known as CC (or not) You be the judge. -- 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 This e-mail message, including any attachments transmitted with it, is CONFIDENTIAL and may contain legally privileged information.
