Re: z/vm page packs at DR
I backup everything. Why? In a real disaster, you don't have a system's programmer. Since you already have to document and teach how to do a standalone restore of the system packs, just repeat for the page/spool/tdisk packs. Formatting and allocating packs is another source of errors. And when there are errors, there are no system programmers to determine and fix the problem.

At the DR site, I run an adrdssu restore job for these packs. This method works fine, however, I'm wondering if backing up the page packs is necessary? I was thinking that maybe I could backup only 1 page pack so that I can get z/vm up and then just init the remaining packs after coming up. Since the page packs are listed as cpvols in system config, would z/vm even come up if it couldn't find all of them? Seems like a waste of time to back them up... At DR site, we bring up a z/os rescue system in order to run restore jobs for both z/os and z/vm volumes. Afterwards, our z/vm and z/os systems run as second level guests.

VM to zLinux Remote Execution
I'm trying to remotely execute a command with CMS as the client and SLES 11 SP 1 as the server. All documentation I've found so far, shows how to do it from Linux to VM. Apparently the problem is, TCPIP for VM only has the unsecured REXEC client and SLES 11 only has a secured sshd. I've searched the VM download page for a ssh client. I've done some Linux searches for how to dumb down sshd (i.e. to allow unsecured transfers). Of course, there might be program products available, but unless they would be zero cost products, it's not going to happen in the short term. Thanks for any help Tom Duerbusch THD Consulting (Still on z/VM 5.2)

Re: VM to zLinux Remote Execution
That would have been a fall back solution. Without spending money for a ssh client, downgrading to REXECD seems like a workable solution. Network wise, I'm on hipersockets, so the risk of the traffic being sniffed should be minimal(right?) And as it is locked down to specified hosts any attempt to access REXECD from another mainframe host, should also be minimal(right?) I see articles about spoofing. Got me somewhat spoofed too G.

Re: REXEC and RXAGENT1
Thanks Alan I was somewhat confused with the Planning and Customization manual, with the section: Starting and Stopping TCP/IP Servers It lists many of the servers and how to stop them, usually with SMSG. It didn't list REXECD which was part of my questioning Kris' post. Apparently, I was in the wrong part of the manual...again.. And the OBEY command you pointed me at, does work at resetting the MaxRestart parm: netstat obey port 512 tcp tcpip VM TCP/IP Netstat Level 520 OBEY command response is: OK OBEY return code = 0 And I see REXECD and RXAGENT1 being xautologged. And...imagine thatit works as advertised! However, now that it all worked, I logged onto REXECD. When I ran my same tests (from MAINT), they still worked. When using guest, it seemed to use the RXAGENT1 server. When using a userid, it xautologged on the user and executed the command. So, I thought that the communication problem that being logged on to the server may only be at startup. #CP IPL CMS (from REXECD) and brought the server up. Both my tests still ran fine. So, is the caution about not being logged on to REXECD or having the secondary user, one of mere caution, or are there occasional things might happen, later, perhaps much later, that fouls up things, perhaps recovery? Anyway, for testing, it seems I can be logged on. But now that it works, I would only be logged on to update the a-disk with some rexx programs that I will be executing remotely.

OK, that makes sense to what I'm seeing now. I never got into using OBEYFILE. Back in the early '90s when VM first got IP, everytime I used OBEYFILE, I wiped out things that I didn't intend to. Never went back to it again. I never caught on to which groups of statements were considered packets of statements.

Re: REXEC and RXAGENT1
I duplicated the RXAGENT1 to make the RXAGENT2 in the directory and added the info in the DTCPARMS. They do have the LINK REXECD 191 191 RR in the directory. When I force REXECD, TCPIP automatically brings it back up. No attempt is made to bring up the agents. The only problem I have with using REXECD with a particular user, which is solved by using the agents, is that I have a list of commands that I'm sending off to be executed and some of them fail with Unable to autolog user message. In other words, the machine didn't finish logging off before the next remote command was being issued. I might bypass this problem by executing a rexx program instead of individual commands. Tom Duerbusch THD Consulting Scott Rohling scott.rohl...@gmail.com 7/15/2011 3:01 PM Only RXAGENT1 is supplied .. which makes me then wonder if these agents are built as they should be -- doing a LINK REXECD 191 191 RR for their A disk, etc? Did you model RXAGENT2 on 1? What you show seems correct.. so searching for clues :) Does the REXECD console show it is attempting to start -- any error msgs? Is RACF installed - if so, is REXECD authorized to autolog? These agent ids are only for anonymous requests.. any trouble using REXECD for a particular user?

Re: SUSE11 and VNC Viewer
Hi Richard I tried following what you suggested... No avail. However it dawned on me that I never got the prompt for the password to get into VNC. (VNC Authentication window) I suspect the timeout I get after two minutes is VNCs response to no password. So, when you are doing the click and hold, is this after you have responded to the password challenge? Tom Duerbusch THD Consulting Richard Troth vmcow...@gmail.com 7/6/2011 10:49 AM Hi, Bob, -- I use VNC rather heavily. From Tom's report, you may be having a different error than I am used to. Also, contrary to Tom's suggestion, I don't start VNC as a service, but run it from user space (even though perhaps running as root) ... sign on, do a 'vncserver' command, then connect with the viewer. In this context, I get a stipple pattern. But that's not really an error. (And it's not exactly blank. Forgive me if you already know all this.) TWM is not intuitive at that point. Assuming TWM actually started, you'd still need to click-and-hold before you get any hints from it. When running 'vncserver' from your shell, the normal operation is that a .vnc directory is created under $HOME. In that directory, there is an xstartup file which controls how VNC behaves. In particular, this is where you get 'twm' as Ray Chu mentioned. I usually just stick with 'twm' because it is light. For serious remote desktop use, it is usually easy enough to change to KDE or GNome on demand. But for use with installers, you probably don't want to bloat of a complete desktop environment.

Re: Creating a Second IP Stack
Where there are many reasons why you might want a second IP stack, if the only reason is to have a back door TN3270 session, then try using the ICC port. (An OSA port configured for ICC.) These are always up and you can TN3270 into them, get a VM logo (in the VM world), and fix what ever problems that messed up the stack. An OSA port configured for ICC, has its own IP stack running in firmware. You can't touch it. You can only configure it. Once configured, it's hard to mess up. Certainly, you will never mess it up by changing the configuration on you IP stack (unless you try to assign the same IP address G. But even if you do configure the same IP address, the first one up (the ICC) wins.) Tom Duerbusch THD Consulting Jeff Gribbinjeff.grib...@gmail.com 3/5/2011 10:07 AM Greetings, I may be a, 'VM-Oldie' but I'm most certainly a, 'TCP/IP Newbie' and, true to form, I'm already wishing to push the envelope a little ... I'm helping to maintain a not-very-busy z/VM system which is pretty-much starting from scratch and currently has no asociated SLA's or the such to worry about. It's not quite a sandpit, but pretty close. I access the system via TN3270 and, in order to allow me to perform surgery on the main TCP/IP stack (bog-standard vanilla configuration, straight out of the box), I'm looking to place a second IP stack alongside the primary stack that will give me at-least a TN3270, 'back door' into the system. My, 'problem' is TCPIP DATA, which appears to be a unique filename. 'TCP/IP Planning and Customization' states quite categorically that TCPIP DATA defines parameters used by TCPIP -client- applications. If this is truly the case then it would seem that all I need in order to implement a second stack purely for TN3270 purposes is to create appropriate 'userid DTCPARMS' and 'userid TCPIP' files on TCPMAINT's 0198 and I'm away. Would I be correct in thinking that TCPIP DATA is, 'merely' read by the, 'client' commands in order (e.g.) to locate the servers that they need to interact with. If this is so, would it be acceptable practise (that is, behaviour that would not bring the Wrath of Chuckie upon me) to keep a second copy of TCPIP DATA, configured according to the userid(s) of the second stack, on a separate minidisk and access that minidisk in front of TCPMAINT's 592 when wishing to, 'converse' with the second stack? (For example, in order to issue a NETSTAT command without needing to specify the, 'TCP' option every time.) I can, of course, discover most of this empirically for myself - and will indeed be experimenting a little (what else to do on a wet Saturday afternoon?) - but if for no other reason that the Fear of Chuckie I would be reassured if somebody with more experience were willing to sanity-check my hypothesis and proposed, 'solution'.

If only #2 were implemented, the new SPOOL command could be entered in the directory entry of such servers via the 'COMMAND' statement, providing the same facility with lower CP coding and documentation requirements.

Re: z/VM 5.4; 6.1
The question comes back to what sized volumes can be CPOWNED? A CPOWNED volume has a bit map that defines the CP areas. The install of VM is really just a DDR restore and the bit maps are defined by IBM. On the smaller volumes, wasn't it one track for the bit maps? And for the larger volumes you needed a second track? I'm fuzzy on if it was a MOD-9 required a second track or it was the largest that used a single track. Anyway, on a MOD-27 or MOD-54, what is on the additional tracks? Did IBM leave them (and tested the fact) that they are binary zeros which is PERM space? Or is there some other stuff out there that might say some cylinders are TEMP, PAGE or other CP space? And was that extra space formatted by CPFMTXA to be CP space? So, in my book, the install can't be done on something greater than a MOD-9. You may be able to build a VM system on any size volume however. Tom Duerbusch THD Consulting Jakub x jszef...@gmail.com 2/9/2011 2:10 AM Hello, Can I install z/VM (5.4 or 6.1) on dasd 9 model 27 ?

Re: z/VM 5.4; 6.1
No, I'm thinking the CP allocation bit maps. Consider a different view. If z/VM could be installed on any model of 3390-3 or greater, why would they say that it could only be installed on a MOD-3 or a MOD-9? To me that means that their install process is model specific. So why? Is it that the CP allocations areas, which are model specific, won't allow it? Is it that the install process determines the model type and then has different install paths? If the model type isn't supported, what does the install process do? I've seen installs of other OS on models greater then what the install supported, and the documentation said that the extra space would not be used for the installation, but you can use that space for other uses. Does the VM install guide say that type of disclaimer? If not, I doubt an install on any other than a MOD-3 or MOD-9 would go good. However, if you are a VM Systems Programmer, just do the install manually and it should be doable. If all you have are MOD-27s, how about creating MOD-3 or MOD-9 minidisks, starting on Cylinder 0, and install second level? The install process would see one of the supported models and be happy. But you may still have a problem with the CP allocation area, when you IPL the full pack. If interested, just try it. An install is only a few hours before you can test. Tom Duerbusch THD Consulting Scott Rohling scott.rohl...@gmail.com 2/9/2011 10:20 AM I don't understand why you say the install can't be done on something greater than a mod 9 ... I'm pretty sure it can - if you don't mind empty space. Cylinder 0 is sufficient.. maybe you are thinking of XLINK bit maps? Scott Rohling On Wed, Feb 9, 2011 at 8:32 AM, Tom Duerbusch duerbus...@stlouiscity.comwrote: The question comes back to what sized volumes can be CPOWNED? A CPOWNED volume has a bit map that defines the CP areas. The install of VM is really just a DDR restore and the bit maps are defined by IBM. On the smaller volumes, wasn't it one track for the bit maps? And for the larger volumes you needed a second track? I'm fuzzy on if it was a MOD-9 required a second track or it was the largest that used a single track. Anyway, on a MOD-27 or MOD-54, what is on the additional tracks? Did IBM leave them (and tested the fact) that they are binary zeros which is PERM space? Or is there some other stuff out there that might say some cylinders are TEMP, PAGE or other CP space? And was that extra space formatted by CPFMTXA to be CP space? So, in my book, the install can't be done on something greater than a MOD-9. You may be able to build a VM system on any size volume however. Tom Duerbusch THD Consulting Jakub x jszef...@gmail.com 2/9/2011 2:10 AM Hello, Can I install z/VM (5.4 or 6.1) on dasd 9 model 27 ?

Re: SET SHARE ABSOLUTE/RELATIVE
We have sufficient enough resources so set share isn't a big deal, however, I do have production set at set share relative 150 and the test systems as set share rel 50. When they are competing, the production machines end up with 75% of the processor and the test machines with about 25%. That seems to be cool with me. You don't want certain machines to be cpu starved. We need CICS users, both test and production to be serviced and all IP stuff to be serviced. That includes DB2 when accessed via DRDA. So, in my minds eye (since we don't have any good performance monitors), I use the relative share to pretty much allow the test systems about 12% of the processor. This should take care of any CICS and IP traffic. A long time ago, I tried dropping the test machines in the basement, priority wise. CICS started abending AICA, IP would fail on timeouts and DB2 DRDA would faile on timeouts. Many times it was quicker to reipl the test system then to determine what failed and restart the task. Since then, test systems always get some cpu. Tom Duerbusch THD Consulting Hughes, Jim jim.hug...@doit.nh.gov 2/7/2011 2:27 PM Thanks for the reply Marty. Long time, no see. Our VSE systems are mainly interactive CICS or IDMS/DC systems during the day. Night time they become batch machines. The CICS and IDMS/DC systems are mainly accessed via VTAM. Our three production systems are each set to ABSOLUTE 20% with no defined target maximum. The sum of our ABSOLUTE SHARE users does total 100%. With that said, we've asked ourselves is ABSOLUTE 20% enough? The manual says once you have defined the minimum target ABSOLUTE SHARE to total 100%, the scheduler reserves 1% for the RELATIVE SHARE users. It goes on to say that once an ABSOLUTE SHARE user has reached its minimum target share it only gets more if system resources are available. What I am looking for is a way to keep the production systems behaving if a production vse system(absolute share), test vse system(relative share) or a cms user(relative share) begins to loop. The more I read about CP SET SHARE the more I suspect it isn't designed to be a panacea for smooth performance in time of trouble. Maybe I should be investigating the VM Performance Monitor to assist with dynamic performance adjustment in a time of trouble. Comments?

I suspect it's trying to keep heavy CPU users from hogging the processors. To get back to the original question, Jim, I think you need to describe what the z/VSE guests are doing. If they're supporting interactive users (e.g., CICS), you'd want one answer from the assembled masses. If they're true batch workloads, the answer should be quite different. Since your system's perceived responsiveness likely depends on how quickly TCPIP (and VTAM) gets serviced, a high share is called for. In your situation, is the same true for RSCS? Regardless, my experience with the conventional wisdom of whether to use relative or absolute shares is dated, so I'll leave detailed recommendations to those with more recent experience.

We used that setting on our test system only. Our VSE TOR and VM guest TCPIP both had high relative shares (1 versus 3000 for regular production guests). Then we started using a performance manager feature of VM Toolkit, it managed share values for us. It set everything the same after VM IPL, but by the end of a normal production day our busiest guests had dropped to the lowest relative share, the ones seldom used had the highest. Meaning my understanding of how relative share worked was backwards or the gizmo in VM Toolkit was. Hopefully Alan or Kris will expound. -Original Message- From: The IBM z/VM Operating

Re: Dynamically adding 3390's
I would think that if this DS8100 was already being used by this box, then the CHPID and PATHs are already defined. If this is a new controller for you, then you need to do the DEFINE for the controller using the existing paths. In all cases, you would have to do the DEFINE device(s) for the new volumes. Then, you can vary on the devices and be off and running. When done, be sure to update your IOCP and put it in the next slot. Otherwise a Power On Reset, will loose any dynamically defined IOCP stuff. Tom Duerbusch THD Consulting Frank M.

z/196 and older Operating Systems
Per the IBM documentation, the z/196 requires z/VSE 4.1 or above, z/VM 5.4 or above and Suse 10 or above. Of course, as those products are the only supported products available. So, did the z/196 break older operating systems? I don't care that the older ones can't use newer facilities. (The z boxes came with dual channel sets which broke unsupported OS versions until migration PTFs became available. For example, at one site, I have z/VSE 3.1.0 running. We were planning on upgrading from a MP/3000 to a new box. My conversion process was to run z/VSE 3.1.0 on the new box in a LPAR, and bring up z/VSE 4.3 on another LPAR for conversion. The Business Partner is suggesting a z/10, but that was 4 months ago. I don't know if the z/196 was available at that time or not. I believe that the z/10 isn't in new production, so a z/10 would be used. Hence we pay for shipping, installation, site prep, no warranty, etc. which isn't in the proposal from the Business Partner.

I see there is a TN3270 application available for the ipad (OTC about $35). Yes. Works fine. The keyboard layouts are a bit icky, but they're usable. I'd strongly suggest a external Bluetooth keyboard if you intend to do a LOT of typing on a iPad/iPhone. You get used to the onscreen keyboard, but you will develop bruises on your fingertips if you do an extended session (and switching back and forth for numbers/symbols gets old very fast). Does tablets have VPN available? Depends on the tablet, and your VPN system requirements. The iPad does (the Cisco VPN client). I believe that some of the Android ones have it as well. As a side question, does tables have apps that use PDF files? Use, or display? Display, certainly. I use iBooks. I assume that there is a Putty type application. Yes. There's a nice ssh implementation for the iPad. Similar apps exist for Android. Also, can you attach, and address thumb drives on these things. There's the rub. The iPad doesn't let you attach a USB drive. Some of the Android tablets do, but that's a device-by-device thing. Still, a full set of VM manuals plus the BSD Unix manuals plus most of the AIX and Solaris 10 manuals is less than 200M, which is doable on most of the tablet devices without scratching the surface of the flash. (sheesh -- just looked, and I have more than a gig of *apps*. Gotta do some housecleaning) As far as communications goes, the more expensive version of the ipad had 3G which seems to require a monthly subscription. Both the expensive one and the cheap one have wifi capability. I would think I could make my Blackberry a hotspot so the cheaper ipad can hitch a ride. I do exactly that. If you have a tether-capable phone, the 3G interface on the iPad is a ripoff. You're better off spending the cash on more flash (eg, the 32G or 64G systems) and sticking with wifi. One catch to watch for is different implementations of WPA algorithms for wifi encryption -- the Apple implementation often requires the hex form of the encryption keys to connect with non-Apple implementations (works great with a iPhone or Apple wifi base station and the Cisco/Linksys implementation, but Netgear wifi doesn't always work with the iPad. Ditto Nokia's implementation of WPA - depends a lot on the individual phone. WEP 128 usually works across the board, but may not be available in a enterprise environment. YMMV.

And cut off when you run out. Gives you 100 cylinders. Gives you 32 MB machine. You can pay for additional bumps in resources. But a total limit as a hobbyist. Of course it isn't us, as a general rule, but the amount of money spent on ring tones, text messaging, ATM fees, etc. makes me wonder. Last year, I bought a new desktop (Lenovo). My first Lenovo. Unlike IBM PCs, it didn't come with a free copy of Lotus. My old PCs are still running, so it isn't a problem yet. But eventually, I have to buy a Suite. Lotus is compatible with what I have, but MS is compatible with my clients. I might be willing to consider a Cloud version if the cost is small enough vs a few hundred for the standalone product.

Yep, I know it is a separate processor/memory and connected somehow, in some sort of internal networkbut.. Can we share devices, like we do between LPARs. Or do we have to have dedicated ficon/fcp connections? Can we share tape drives? Can we share printers? We have a site, that has an AS/400. And, of course, we are mainframe (z/890, z/VM, soon to upgrade to z/VSE, and zLinux). And we have been looking at upgrading the mainframe, just as a cost savings. But, as we are under budget cuts, cost savings are out G. Cost money to save money. We need to spend less money this budget year, and multi-year agreements are out. Really makes it hard to save. I'm thinking about the idea of combining datacenters. The people will all remain as we still need the AS/400 Operations and Programming staff. Operations would move here. Programming can stay there, remotely. Couldn't close down their machine room as all their servers are there. So the question would really be... Cost savings in hardware (processors). Cost savings in reduction of duplicate devices (tape drives, printers). Cost savings in software (z/VSE of course. Is there any for the AS/400 software?) So is there a real, bang for the buck, for an existing AS/400 shop to be combined into a small, z shop? Of course, we still have no money to do anything...but it may be an interesting discussion.

Re: IBM z/196 and AS/400
Ok, I've reread the announcement letter. I see my confusion... The z/196 supports Power Blades. And Power Blades support i5 (the operating system formerly known as i5.OS or OS/400). It doesn't mean that z/196 has the support for the i5 OS. Which is kind of strange. Is this a licensing issue where IBM couldn't get a license for i5 to run on the z/196? Different divisions have their own chiefs Or is it that there is some emulation involved with running i5 on POWER that isn't available on the z/196? Or is it that there are some device drivers, performance metrics that can't be obtained, or something, that means i5 isn't available for production, at this time? Oh well I guess that is why there hasn't been any chatter on the forums about this.

Re: Jumbo Frames
If you have a single engine, I wonder if you are hitting the same class of problem that Websphere has on a single engine? That is, you have two active tasks in competition for CPU time. i.e. two stacks, one engine. stack A sends a packet The cpu is taken from Stack A to service Stack B. Stack B gets the cpu and sends back the ack. The cpu is taken from Stack B to service Stack A. There are some functions that will never perform well, with a single processor. Could this be one of them? Tom Duerbusch THD Consulting Eric Schadow escha...@davisvision.com 11/17/2010 11:38 AM Karl Check if jumbo frames are enabled on the switch the mainframe is plugged into.

Re: IPL VM/VM Issues
And, the VSE side of IBM already has most of the code writtenVSE/VTAPE. The IP flavor, should work under VM with only minor changes. The VSAM flavor, well since the VM side sun setted VSE/VSAM, and a CMS minidisk is limited to the size of a pack, there might be a lot more work in converting the VSAM I/O to something supported under CMS that can support hundreds of 4 GB (max) virtual tape files. Or perhaps even get rid of the 4 GB limitation as that was a VSAM limitation. If there are other vendors that can trap the tape I/O from CMS, then I'm sure that the VM development folks knew how to do that long, long time ago.

Re: Running back level VSE on a z/10 with VM6.1
Yes, it won't run as is. Starting with the z/890, there are dual channel sets which VSE/ESA 2.5 and below were not aware of. VSE/ESA 2.5 had a real PTF to support this. Anything under VSE/ESA 2.5 had a migration PTF to support it, at your own risk. The migration PTF is a piece of paper, with some locates and zaps. Works fine if you haven't put on much supervisor maintenance. Contact your Business Partner. With the PTF, I know that VSE/ESA 2.3 will run on a z/10. The same should be able to be said for VSE/ESA 2.2. It is a one way zap. In that once applied, your VSE system can only be IPL'ed on a processor with dual channel sets (z/890 or better). If you want to be able to backout, make sure you have a good copy of DOSRES prior to putting on the zap. Also, your current standalone restore utilities need to be updated for a dual channel set processor.

Re: Is there a SLES 11 starter system and more
IMHO, the starter system is really only useful, when you don't, already have access to a Linux system for code distribution. Any Linux system, with sufficient disk space, can be made into a NFS server, or a FTP server. In my case, I have to download the DVD images to my PC first, and then upload them to my NFS server (due to network security that I haven't decided to fight...yet). Then install from the NFS server (of FTP server). I'm also installing SLES 11 SP 1. I'm installing it from a SLES 10 SP 2 NFS server. Once SLES 11 SP 1 is tested and documentation produced on how to install that flavor or Linux, one of my first production servers will be a SLES 11 SP 1 NFS server to serve for installs. Then all other installs will be from a SLES 11 SP 1 server.

Re: GCS Session managers
Thanks all for the suggestions. I've used most of the sessions managers in the past. Perhaps I can use the TN3270E alternative. On my PC, I've had sufficient problems that I wouldn't do the same thing to Operations, but thinking about how they use itit just might work. The problems I have is... Right now, I have 10 TN3270 sessions going to VM/VTAM and half of them are using Tubes/GCS. Then I have 6 Putty sessions, 8 web sessions, the email client with 6 opened emails, (when an email wants me to do something, I leave it open until I've completed the task), 4 Word documents, 8 Explorer sessions. 2 DOS sessions, along with a few more. Yes, I have hit the limit of number of opened windows in WIN/XP. So tabbing around just isn't useful G. (my task bar is 4 deep). However, I have my second PC that I put 7 TN3270 sessions on, and tabbing around (alt/esc) does work kind of nice...similar to tabbing on Tubes. Next step is to configure some more ICC ports and see what problems I have (over a month or so), with the VSE master consoles (01F) being used there. Right now, our consoles are on real non-SNA 3270s. Good solid connection. VTAM is only down when the system is down. The IP side just isn't as solid as the VTAM side. DNS server is down. Someone change network routing. The license for the TN3270 product expired. Someone unplugged something. Some of the same problems that the SNA side use to have. But now, no changes to the SNA side need to be made (much more stable that wayG). Anyway Configuring the ICC for these additional sessions, Buying standalone copies of a TN3270 product, Replacing the 3270s with PCs, It all might be doable, now that Macro/4 doubled the price for Tubes/GCS. Over the next month or two, if anything else needs to be addressed. Thanks Tom Duerbusch THD Consulting Marcy Cortes marcy.d.cor...@wellsfargo.com 3/11/2010 12:36 PM Yeah, us too.

Can keep all the sessions active, if the PC/Terminal is disconnected. 4. Would be nice to do cross domain to VSE VTAM for CICS sessions. 5. Support 3270 Model 2 thru Model 5 terminals. A lot cheaper than $20K per year for Tubes/GCS. Thanks Tom Duerbusch THD Consulting

Re: Amount of CP dump space needed
There was a problem with spxtape which I thought was fixed by z/VM 5.4. But as we see it, on z/VM 5.2 SPXTAPE tried to buffer as much as possible. As spxtape is a CP function, all of its buffers end up requiring slots on the CP Dump dataset. When spxtape finishes, there is no automatic way off reducing the amount of slots used, as an CP abend might happen a few seconds, minutes after spxtape ended and well, what if it was the cause?. I take it that there are other CP functions that may end up buffering or using storage that requires slots in the CP DUMP area. Something like Q RECORDING and if nothing is servicing those records, CP is buffering them. Of course, the page tables and all that storage related stuff needs to be dumped in case of a CP abend, so the CP DUMP slots are allocated. So the memory size of the LPAR is a consideration, as well as the sum of the virtual sizes of all the machines that are logged on is also a consideration. Tom Duerbusch THD Consulting Marcy Cortes marcy.d.cor...@wellsfargo.com 1/5/2010 1:09 PM How is the amount of CP dump space calculated? We have a system that seems to be using at lot more than the others. Everything is pretty much identical across the LPARs HW wise (access to all the same devices, etc) and SW wise (z/VM 5.4 RSU 0902). Here's an example. System A: q dump DASD F1B0 dump unit CP IPL pages 1140129 Ready; T=0.01/0.01 13:02:40 System J: q dump DASD F00D dump unit CP IPL pages 169959 Ready; T=0.01/0.01 13:03:32 Both systems have 32G (28 central, 4 expanded). If anything System A has less memory usage (does not page with 10 linux ) and System J does (16 linux). I tried set dump off and then set dump DASD to see if that would change the numbers. The number on system A grew (from 1131137 to 1140129) while System J did not change. Why would be they be so radically different?

Re: zVM 'disk wiping'
If you are talking about reassigning disks to another system, a CMS format is good enough. If you are decommissioning the drives then talk to the vender or have them crushed. A DASD subsystem isn't easy to destroy anymore. 1. You have pools of extents, and not all extents may be used, but they may have been used (and the drive deleted). 2. Parity shouldn't be a problem. 3. Spare drives can be a problem. From my research, the vender has a product/method, of meeting DOD specifications for destruction of the data. Else they would never sell to the government.

Do 'passes' imply that each pass is covering more 'area' or something? Whenever I do things like 0 a disk using the dd command -- I assume the entire disk is being written to and any subsequent dd commands are unnecessary and redundant. Nope, not silly at all. The idea is that repeating the writes with different patterns of data blurs the magnetic image on the disk of the original data, making it progressively harder (but not impossible) to recover the data via laboratory means. The DSF INSPECT command is pretty effective for decommissioning disks, but it's not good enough if you have milspec erasure requirements. Melting is pretty much safe. Use of old disks as live-fire ordnance test targets is also popular (and much more fun). 8-) - If we do a DIRM PURGE user CLEAN -- is that sufficient to meet any DoD rules, etc concerning securely wiping data? No. At minimum, DSF INSPECT, more common: destroy the platters completely. Anyway, to your real question: there is allegedly/apparently latent magnetism in a bit, such that it's at least *theoretically* possible to recover data from a formatted drive. More than theoretical. It's not easy, but a good forensics lab can do it. Has anyone ever actually done this? Not that I know of, but I haven't really looked. Obviously they'd need physical access to the disks and a fair bit of time. Yes. One *past* (I don't do that stuff any more) client of mine manufactured instruments of policy -- aka military weapons. One of their other contractors wiped an important pack several times and they had to send it to a secured forensics lab for recovery. 4 months and several million dollars later, they were able to read about 80% of the data. -- db

If check is true, then issue a warning message and cancel the action. Option defaults to ON, can be turned off by class A user SET command.

The user didn't define their storage allocation, and in practice can't do that at all. So the user didn't set up the situation which caused the integrity issue, the system administrator did. The system administrator is in control of the CP Directory, and as such, decisions are left to him. The system doesn't question what he does, within the definition of the syntax, semantics and limitations of the directory entries and commands. If you want to define a large virtual machine, should the system question your authority? The system could check the memory and page space against each directory entry as the binary directory is built, but this would add time to the directory build, and does not account for the situation of planning to add more page space before logging in the new directory entry. Maybe a warning of User exceeds paging space could have averted this situation, but again, each user would have to be checked against the running system. It shouldn't keep you from creating the entry, just let you know that there might be an issue if you actually use it.

Yep, that is what he said... And as I don't trust computers, you know I never trust people G. If it isn't that, then the printers need to be attached to the second level system during the IPL of the second level system. In my experience, printers don't sense too well. If you IPL with the printers attached, and it still doesn't sense properly, perhaps there is a SET RDEVICE in the autolog process, or in the Operators profile. But, if this volume was truely cloned, all that should be there. So that brings me back to IPL with the devices attached and see what you get. Or at least attach one of them for testing.

VM LPAR has 175G of memory and a flock of Linux Oracle guests... Several guests needed more memory added so the directory was updated and one by one the guests shutdown, logged off and back on. So far, so good. But... In changing the memory for many guests, and it being late at night after a long day, while meaning to set a guest's memory to 9728M, it got set to 9728G. When that guest was cycled we see the message on the console that it's memory was limited to 8TB (HCPLGN093E), then the VM system appeared to freeze. We couldn't get in via TCP/IP, or the HMC Operating System Messages screen, or the HMC Integrated 3270. Finally had to IPL.

Re: How much memory?
My initial guess is that you need about 1 GB for your current workload. Some things to check: 1. Do a QSYSOWN qsysown ** Summary Information: Total-Pages TypeAllocd In-Use %-Used SPOL 1201680 348517 29.0 PAGE 1201680 172559 14.4 Look at the %-Used for PAGE. If it is near zero, where it should be if you never paged, great. If it is not near zero, then you did/have been paging. 2. Find how much storage you are using. Do an IND USER for each guest: ind user stlesa2 USERID=STLESA2 MACH=ESA STOR=700M VIRT=V XSTORE=NONE IPLSYS=DEV 0120 DEVNUM=00073 PAGES: RES=00021448 WS=00021444 LOCKEDREAL=0004 RESVD= NPREF=00011685 PREF= READS=00015515 WRITES=00051555 XSTORE=000646 READS=003233 WRITES=025769 MIGRATES=021694 CPU 00: CTIME=92:37 VTIME=721:27 TTIME=839:31 IO=335062 RDR=015839 PRT=790969 PCH=078332 Look at the RES figure. This is the number of pages that machine is using now. Sum up all the pages for all the currently logged on machines, multiply by 4K an that is the storage your guests are using. 3. Do a Q FRAMES: q frames All Frames: Configured=163839 Real=163839 Usable=163839 Offline=0 Pageable=148743 NotInitialized=0 GlobalClearedAvail=32 LocalClearedAvail=32 LocalUnclearedAvail=31 The Configured minus Pageablejust say VM overhead. Sum up 2 and 3 and that is the amount of storage you need at your current paging rate (which should be near zero). My guess is you have 6 GB left. 1 GB for your system. 1 GB taken for microcode. 6 GB remaining. Taking 2 GB for the zLinux LPAR is a good start. You will have a little more than a GB for Linux stuff. On the Linux LPAR, make sure you have 4+ full paging packs, as you are going to page here. Perhaps give .5 GB for expanded storage, also, as you are going to page here. Don't forget to implement vdisk support so you have vdisk packs for Linux swap areas. Good time to also bring up vswitch/guest LAN. Of course if you have a performance monitor, getting the right amount of storage is a lot easier, but it is also doable manually. How often can you reconfigure your production LPAR? If rare, push for a performance monitor as it will save you Power On Resets as you keep reconfiguring your production LPAR. If you can do it weekly/monthly, well, take 2 GB, monitor for a while, take another 1 GB, monitor for a while, take another GB, perhaps give back 512 MB. You know the drill.

I have a z800 running z/VM, which has two production z/OS guests, and the usual collection of CMS guests (TCPIP / OPERATOR etc). We discovered recently that the z800 has an IFL (long story - don't ask!) and would like to steal some of the 8GB currently allocated to VM, to run up a VM / Linux LPAR for a POC. The two z/OS guests are defined at 256MB 512MB (Bill Gates, are you watching??), and don't page. In your most esteemed opinion, what could I steal from the VM LPAR without hurting it's and the guests performance / making it page? Personally, I think 2GB would be enough. Comments and opinions welcome.

SSIDs anymore?
Subsystem IDs I know you still have to define them in the controllers, but are they used anymore? We use to need them for EREP, but all the current hardware seems to have their own service processor that makes EREP useless. Perhaps large shops still need them for something. What happens now, if you have two controllers with the same SSIDs? Obviously, one of the clients is installing a controller this weekend. Hence the subject came up.

Re: SFS - Moving File Pool Minidisks to Different Physical Devices
I thought SFS used standard CMS mindisks with a single mode 6 file on them. If so, just create a new minidisk that has at least the same amount of 4k blocks and copy the CMS file to the new minidisk. Then swap the directory entries. Note that this is a physical copy and can't be used for expanding a pool. But I thought I used it when migrating from 3380s to 3390s a long time ago. You can't just drop a pool or disk as the space has been mapped. You can tell SFS not to use those blocks anymore and create new pools on the new devices.

Re: Multiple zVM Lpars - Resource consumption
I agree of most of the points, but there is a lot more to memory for VM than 64 MB, but that is up to you. 1. You will have a duplicate area for MDC. I don't know. Are you planning on decreasing MDC on LPAR0 to give to LPAR1 or just duplicate it. I use 100 MB for MDC on each of two LPARs, but without a performance tool, I don't know if I have over allocated it or under allocated it. 2. Expanded Storage. You need some if you are a VM paging environment. Did you reduce the size on LPAR0 to give to LPAR1? Or not? If you are talking about 25% of storage for expanded storage, that dwarfs any other VM usage of storage, well other than paging. VM only needs 2 3390-3 drivesthat is until you add 5-6 paging packs, and a couple spool packs, and don't forget SFS packs (I keep SFS space on their own packs). And there may or may not be a dump pack as well as t-disk pack(s). Back on storage, with poor planning, you can end up with another GB of memory for overhead functions. That might be painful.

IBM DS6800 maintenance
Has anyone tried a non-IBM maintenance provider for one of the IBM DS disk subsystems? Are there companies that do this? Our 4 year warranty is up on our IBM DS6800. We are required to go out on bids, if it makes sense. It only makes sense, to spend the XX hours for the bid process, if there are competitors. Currently, we have 24X7 with the service uplift. i.e. When the DS6800 calls home, an IBM CE is dispatched. G Where the call-home feature can send a request to anyone, we are also concerned that another provider would have a remote support process available. We have had several problems in which the remote support team, got us back up and running. Thanks Tom Duerbusch THD Consulting
Re: Testing Linux Z/vm
With Oracle, someone is listing to the PC side of the house. That is, inexpensive MIPS, inexpensive memory, expensive I/O. Hence you want SGA to be as big as possible. On the IFL side, MIPS are still relatively expensive, memory is still relatively expensive, and assuming you are on FICON, I/Os are cheap. Since you are just testing, cut the SGA in half, make the Linux guest about 512 MB bigger than the SGA, make the swap disks, VDISKS and prioritize them. You shouldn't have VM paging. If you are planning on pounding I/O during the testing, don't forget I/O balancing on you DASD subsystem. Make sure heavy I/O is spread across raid arrays and controllers. The default tends to be accending CUA tend to be on the same Raid adapter, until you jump to the next one. Now, if you are really doing a full up Oracle test, that is, a full set of applications, driven by some sets of test scripts, you are going to need someone to configure your system for performance (of course you have a performance monitor for VM). Your current Oracle platforms were not setup for performance in a day. Don't expect that on the mainframe, in a day. But most testing, isn't in this arena and you can grow and tune the system as you go. It will be interesting to hear the progress of your testing.

And that is bad ;-) As Rich says, you can't reduce the virtual machine size without also adjusting Oracle's expectations (SGA and PGA).

Are there any tricks to get the installs to work? The theory is that with the layer 2 network in place we will be able to move Linux guest from one z/VM to another and potentially move from one box to another box as long as the OSA's on them are connected to the same layer 2 network and that the OSA's are defined the same so that the Linux guest can retain their IP address's no matter which box they are running. Supposedly for load balancing and when maintenance is required on the z/VM systems there will be minimal outages on the Linux guests. Hopefully I have made some sense.
Re: Maintenance Hot Standby
Where you can do duplicate volumes, which was really necessary in the old days, before RAID, and head crashes... But with maintenance, you already have it. i.e. 190 is where CMS is. 490 is you apply maintenance. Swap the disks to put in or swap out, maintenance. (you will still need to resave the CMS segment) CF1 is your current CP system. CF2 is your backup. CF3 don't touch. Copy CF1 to CF2 and apply CP maintenance. IPL normally with CF1. IPL with CF2 to backout. This is defined on the SAIPL loader screen. If you want to, you can still have a backout volume. One suggestion is to copy 540RES to 540OLD Apply maintenance to 540RES. If you need to backout, IPL the standalone utilities and rename 540RES to 540NEW and 540OLD to 540RES and IPL the new CUA. Of course, you could do a standalone DDR restore (or what ever is you favorite backup product). When I get in trouble, I can IPL one of my old VM systems 420RES, 510RES, etc. Good when you flashcopy a CP volume and don't rename the copy.

Re: DB2 Problem
The view is a join of two tables. The view always has the same number of records as the base table. I'm joining in descriptions into the table, instead of having just the description codes.Referential integrity makes sure there is a match. Also, if there are no records being added, the merge record count always equals the purge record count.

Re: What we must do before we claim the zlinux server is in production stage?
A lot of it also depends on local practices. 1. Backupsscheduled..and monitored. 2. Disaster recovery. 3. Someone, other than yourself, trained, on fixing common problems. 4. Usually, the working size is bigger as you have more users. Change the virtual size and monitor the vdisk swap disks. 5. SET SHARE a little higher, but only if you really need to. 6. Perhaps QUICKDSP OFF. Only if q drops have become a problem. 7. Some method for Operations (or others) to make sure the machine is operating properly. 8. Automated startup and shutdown. 9. Be comfortable with restores. 10. Be comfortable with applying maintenance, and backing it out. 11. Documentation (what? did I say that...n) 12. Make a decision if it should be in its own LPAR, without VM. I doubt most of us have that case. 13. Should it be part of a VSWITCH, or have dedicated OSA addresses, perhaps with the port (ethernet) dedicated if it needs the bandwidth. 14. Some sort of IP fail over. 15. Service contracts on your hardware/software. 16. A good performance monitor. (I don't have one, money, but it makes things a lot easier and faster to respond and debug.)

Re: Z/VM and 3590 tape speed
You're getting confused between tape drive speed and channel speed. The IBM 3590 E and H drives will read/write to the tape at a rate of 14 MBs. Multiple that rate by your compression rate, if you have compression turned on. The FICON channel, can operate at 200 MB or 270 MBs (on a z/890). So if you had 2:1 compression, you would see a transfer of 28 MBs. Uncompressed it will be 14 MBs at best. And that is what you are seeing. These are data streaming drives. You have to feed the beast. If your source (disk) can't keep up with the tape drive and it's compression, you will see much, much lower transfer numbers. Tom Duerbusch THD Consulting Hughes, Jim jim.hug...@doit.nh.gov 6/1/2009 1:08 PM We have Z/VM 5.4, with 4 3590's attached to the z890 using FICON Express with the 2-Gbps feature. The tape controller is the A60. I am doing some tape speed tests and my results are not very good. I have a pipeline(look below) that writes 65,500 byte blocks to the 3590. I used the cms command TAPE MODESET ( NOCOMP/COMP to turn compression off/on. I see around 14 MB/sec with compression off and 28 MB/sec with compression on. The 3590 Planning manual says the 3590's should operate at 200MB/sec when using FICON with the 2-Gbps feature. There maybe a problem with my pipeline or my expectations. Here is the pipeline.

Re: Z/VM and 3590 tape speed
Actually, it's the opposite. FICON is the only way to drive an IBM 3590 drive. ESCON is way, way too slow. I have ESCON attached B11 (9 MB/s transfer rate). I get about 4 MB/s when controller hardware compression is used. I get about 6 MB/s when compression is turned off. They are about twice as fast as my bus and tag 3480 drives. Tom Duerbusch THD Consulting Hughes, Jim jim.hug...@doit.nh.gov 6/1/2009 1:55 PM I am looking at table 3 on page 10 of the 3590 Introduction and Planning Guide. It mentions two things of interest: Device Data Rate(native) and Data Transfer Rate(maximum instantaneous). Device Data Rate for the E11 is 14 MB/Sec. Data Transfer Rate depends on the channel. I guess what I am reading says the tape will move around at 14 meg/sec no matter how fast I get the data to the device. FICON for tapes is a waste of time. When would FICON for tapes be a good idea?

Re: IBM 1401
You couldn't fee the paper tape in backwards, the sprocket holes wouldn't line up. However, you could feed the tape in backwards if it was also up side down. Now that really took someone with some smarts to do. I still have my Teletype ASR33 with 8 level reader punch, which included a 44 pound 110 baud modem. Still works. I do have spools of paper tape as well as a spool or two of mylar tape. For a few years, back in the early '80s, I used it for communication to TSO. Then I got a TRS-80 Model 1. I used the Teletype modem, for communication with the TRS-80. I would download programs to my floppy, edit them, and upload them to compile. Really wasn't worth it. Usually took more than a 30 minute TV show to download and upload my PL/1 programs. Anyway, it made a racket that my apartment neighbors didn't like too much. G In my world, before transmitting something for paper tape use, you used the here is key that would punch out a leader. That was the start of any tape. I also recall there was some method that punched out arrows (i.e. forward pointing carrot), that also gave operators a good indication on which way the tape went in. Tom Duerbusch THD Consulting (RIP Grey Stripe, a great cat and my buddy for, just shy of 19 years) Schuh, Richard rsc...@visa.com 5/29/2009 1:30 PM If the radar signal was strong enough to wipe the core, I wonder what it did to the synapses of the person posted to guard the door. In the early '80s, the state of Missouri bought a fleet of new patrol cars for the highway patrol. After a few days, many of the officers started complaining about headaches, Upon investigation, it was determined that all of the officers who had reported the headaches had been using their radar units extensively. After more investigation, the problem was solved by moving the radar units so that they did not point directly at the back of the driver's head. I wonder if all of these systems that used paper tape were programmed so that they could properly read the tapes no matter what the orientation - frontwards or backwards, right side up or wrong side up. Some of the early readers could read the tape regardless of the orientation; however, the data would look very odd if the orientation were wrong. It is scary to think what would happen to an ICBM's targeting if the tape was not fed in correctly. I hope there was something done to prevent that type of problem.

Another paper tape story... when I was in the US Marines (1971-1977) working in the Tactical Air Command Center at MCAS Cherry Point, North Carolina one summer, an important computer kept failing at random intervals. That computer translated radar screen paints (bright blobs) into symbols that we could interpret on large displays (i.e. different symbols for different aircraft; and different symbols between friendlies and bogies). When examined after each failure, the core (yes, real core) memory was always wiped clean. That computer (and its tech) was housed in a metal box (IIRC, about 6'x10', 8' high) which was transportable on the back of a 2 1/2 ton (6-by) truck, or by helicopter It was located about 15 feet from another similar box with all the radar gear inside, and large radar dish on the top. After a few days of random core wipes, someone noticed that the core wipe only happened when the door to the computer hut was momentarily opened as the radar dish swept past. While aimed much higher, there was enough residual power from the dish to wipe the computer's core memory clean. Memory was reloaded (back on track now) from dependable paper tape. Someone was stationed outside the computer hut for the rest of that day until it could be turned around with the door faced AWAY from the radar dish sweep.

VSWITCH and packets
When mainframes just started getting into IP communications, one of the things we were warned about is to filter out any unnecessary IP traffic that is not for the same subnet that the mainframe was on. The reason that I remember, is that the IP stack looked at every packet to see if that packet was destined for itself. Hence an interrupt was generated for each packet sent on the LAN. Ok, now we are on VSWITCH and Guest Lans. Does that same problem exist within the VSWITCH/Guest LANS? i.e. If I have multiple guests on the same internal LAN, and I FTP a file from one guest to another (or for that matter, out to another platform), it would seem to me that every guest on that VSWITCH/Guest LAN would wakeup to see if that packet was something that it needed to be concerned with. I don't have a performance monitor, so I don't see a problem G, but I wonder if this could become a problem. Right now, I have plenty of CPU. I can afford to waste it. In the future, that might not be the case. I'm wonder if I'm going down a scary path, that is just going to get darker and darker, until Tom Duerbusch THD Consulting (Hope WAVV was fun and good.
