Create a file with the directory entry VMIRMAINT shows you called VMBACKUP DIRECT. Then use DIRM ADD VMBACKUP to add it. DIRMAINT does the rest.

Re: DF/DSS backup of z/VM volumes
What is wrong with using CPFMTXA to format and allocate your VM volumes. Most Modern DASD subsystems are doing the basic formatting of the DASD volumes and all that is needed on VM is to format cylinder 0 and Allocate the volume as all PERM. Then format each individual minidisk as needed. If you need CP OWNED areas, Make sure you format all these areas using CPFMTXA. You actually answered your own question. If you don't make a habit of doing the CPVOL FORMAT on every volume, at some point in the future, you'll allocate a disk with non-PERM areas, forget that you haven't done the CPVOL FORMAT, and Much Sadness Will Ensue. Better to just make a habit of doing the format as part of putting the volume online to VM. One less bullet to shoot yourself with. -- db

Re: z/vm 5.4 DVD installation
How this will finally be delivered is still TBD. As I indicated, this is a known requirement that we continue to work to deliver a solution. Even though it sounds simple to burn DVDs, there are other complications here. Just a suggestion: HP solved this problem by encrypting the existing software packaging with a key that (combined with the CPUID) would allow you to extract the package to local disk and then install it normally. I get 20 DVDs every 6 months that have EVERYTHING (every single HP operating system, service pack, applications, the works) on them; I can only decrypt and use the stuff I've paid for. I can get keys from a web site and trade them in if I change CPUids. Scales well in that HP gets to make a really BIG production run of the DVDs, and they're worthless without the keys, so HP really doesn't care if we copy them for other sites or give them to people -- in fact they encourage it because it saves them money on DVD production and they get green company points for saving energy and reducing waste. No product owners had to do anything at all to accommodate the method, and the approach of having EVERYTHING on local media with 0 delivery time is a real plus. Makes DR a lot easier when I know I've got install media for everything we own that has an HP logo in a form that fits in a lunch-box. Just something to think about. -- db

Yes, that's a possibility, but it doesn't really address the base problem, though, which is to reduce the number of platforms to 1 or 2 at the most. What we observe is the customers stratifying down to Intel + Z (mostly due to the embedded nature of z/OS into core business), and any of the specialty architectures are having a lot of rough sailing to stay in play. Certainly SPARC and PA-RISC are past it, and losing Apple put a really big nail in the Power coffin. While I really like the Power chipset design and the pSystem management tools, it's a very difficult sell right now unless you have specialized problem sets that play to its strengths (large-vector operations like those common in bioscience or image processing). Writing an emulator for the iSeries on Intel would pretty much kill its advantages for non-NIC completely; the cost per performance numbers are just too good for raw MIPS on Intel/AMD compared to the cost of support for exotica.

AIX Died a slow and natural death on the mainframe in the 1980's. Not really a fair comparison. AIX/370 was a perverse evil mutant thing from hell that didn't die a second too soon. Modern AIX (ie post-AIX 4) is actually a pretty nice OS, and a lot different from AIX/370 or AIX/RT (which spawned it).

Re: VM operator console?
Trouble with a 'real' console is the need to be a locally attached 3270 device. I understand that to mean a 3174 or similar device. We don't have any. All our MVS consoles use the ICC OSA interface. If you've got an ICC, then define one of the logical devices on it to the VM LPAR and have it be the console in SYSTEM CONFIG. It's a waste of a perfectly good terminal, mostly - with no CMS users, there's very little for an operator to do on VM - but it makes all things equal from an operator POV. If you have some way to set up a NJE link to z/OS, you can route things with PROP to z/OS and handle them in Netview there. Either RSCS or the NJE Bridge does a nice job of that.

Re: Mainframe education/training
What's the good and bad news about today's mainframe education? I think the good parts are that there is more of it occurring. The negative side is that there continues to be a great deal of confusion (most of it generated by IBM) that mainframe = z/OS. Much, if not all, of the advances in training have covered exclusively z/OS education, not System z education. That may change soon, but I can't say the state of real System z education has improved much at all. What's missing? z/VM education Linux on z TPF VSE Large systems engineering Batch processing education (this seems to have completely disappeared) What works? Classroom instruction? Online training? Self-study courses? Books? User groups? Combinations of the above. Online only is of limited value, especially if you don't have a lab system you can break. Do employers pay for it? Is it a necessity or a golden perk? Is it safe in the budget or a first thing to get whacked? If what I needed existed, I'd pay for it. User groups are generally as effective, especially if well-organized. What's happening in local mainframe user groups? Well, Hillgang does pretty well.
Re: Mainframe education/training
I tend to agree with 99% of what Mr. Boyes said. However, the educational responsibility needs to be placed more upon academia. For them to teach UNIX / Linux is a given ability. The lack of educators with mainframe skills and knowledge along with their respective teaching tools limit in today's schools. I think another problem with the current approach is that IBM and others approach the problem with a prepared curriculum that they want to have taught. This approach works pretty well with technical and vocational schools, but I think it misses the mark with the 4 year schools because it's not easy to get new curriculum added to a true university program, and most of those organizations have a difficult time accepting classes they have to rely on remote resources to teach. There's a contractual obligation there that IBM has partially addressed with donating hardware to some schools, but expecting pre-prepared materials to go into place is a hard sell when competing with other areas. I think another interesting observation has been the fleeing of students from CS of any kind over the last few years. Many of them were going into finance or business - I wonder if that will continue? If not, then there may be some interesting opportunities to capture those students as they try to change course midstream.

Re: SLES10 Client
While implementing the SLES exec for the SLES10 full-service server, it asks for a MAC address. (I thought the MAC address was automatically assigned. Why is it asking for a static address?) We are using OSA GB-EXP. You should respond no to the layer 2 prompt here. Nothing in the setup process needs layer 2 access. In general, it's asking so that it correctly identifies the interface you want to use. CP generates a random MAC for the last 3 bytes of any virtual interface (the first 3 bytes are set by MACPREFIX in SYSTEM CONFIG), so if you are going to use the layer 2 function, it matches the virtual MAC to identify which interface to use.

Re: VM RSCS as RJP to JES3, replace current process and last 3745.
Doesn't JES3 speak TCP/IP these days? If so, use the TCP/IP NJE driver to connect RSCS to JES3. I think it does (or it's trivial to use our NJE Bridge to provide an impedance matcher), but it sounds like the original setup has some kind of modified RJE exit on the JES3 side that sets the default for output to the JES system, not the originator of the job. In that case, you'd have to apply those mods to the NJE driver in JES3, which is not trivial. I think they are going to have to make some changes in the job stream to tell JES to dump the output locally, or make the mod to the NJE driver if they want the same functionality. It's not clear to me whether the specialized commands he's talking about are on the JES side or on the RSCS side, but in either case, they're looking at some refit.
Re: VM RSCS as RJP to JES3, replace current process and last 3745.
That would probably work for output, but if they're used to job progress messages on VM from JES via NJE msgs, that would break message routing, I think. Worth a try, though. Rob's idea is intriguing; the approach of letting a service machine mung the JCL into IEBGENR and submitting it via the internal rdr is clever (and gets the text processing work out of assembler and into REXX and Pipes, which would be double-plus good in terms of easy maintainability as well as getting rid of a JES exit or mod). If the //*MAIN ORG idea works, that'd be the way to implement it. Whatever they do, though, I think those custom commands are probably toast.

You can use OUTPUT or FORMAT statements as well but //*MAIN ORG might be best. I don't know what 'JL' is but we send jobs and data from zVM to zOS sendimng output to various vendor softcopy and output storage products. Some need special output classes.

Re: VM RSCS as RJP to JES3, replace current process and last 3745.
Since we have VM/RSCS appearing as a RJP workstation to JES3 using EP and a 3745, can it do the same using the SNA protocol to look like a 3770 device, but minus the 3745? If I'm reading the RSCS docs correctly, no. The RJE drivers really do expect a physical line, as far as I can tell. The exit customization guide also seems to point that way.
Re: Spool
Where could a 'newbie' find a comprehensive explanation of Spool? ie What it is intended for, how its used by VM and potentially other products/tools/applications. Ask here. 8-) Originally, on CMS-intensive systems, spool areas were for two purposes: 1) a place for virtual machines to submit unit record input and output for processing by CP on real devices (eg, print files that CP would drive on a real printer, incoming card decks from real card readers that needed to be directed to a virtual machine, etc). 2) a place for virtual machines to put data that needed to be processed by other virtual machines, eg console logs, files, etc that are produced by one virtual machine but another virtual machine has a need for processing. The PRINT and PUNCH commands produce examples of #1. SENDFILE, DISKLOAD and friends are examples of #2. Around VM/XA, spool acquired two new purposes: 3) Store DCSS (discontinuous shared segments) which can represent shared data mapped into multiple virtual machines. 4) Store NSS (named saved systems), which are IPLable blocks of code that can be IPLed by name, eg CMS, GCS, etc. DCSS and NSSes were around before this, but they were stored in special areas that had to be managed carefully, and you often had to fuss over a lot of things to keep them updated; turning them into files in spool made that process a LOT easier (and gave you an easier way to back up and restore them via SPTAPE and SPXTAPE). Today, most VM systems that support primarily Linux guests use spool only to capture console logs and present them to other virtual machines for archiving via tools like PROP, or to communicate with z/OS via RSCS. CP can also allow paging to overflow into spool if things are really overtaxed, although this should NOT be a normal thing on your system. Other products often use spool to communicate with each other by sending small transactions as files in spool from one virtual machine to another, kind of an implied transaction queuing system. RSCS (or other NJE implementations) can move files between spool areas on different systems, so servers can be separated. There's lots of other useful stuff you can do with spool. It's hard to describe it all, because it's so varied. I like to capture console logs and send them to a single virtual machine for analysis and archiving. I could do it with a central syslog server, but what if the network breaks? Spool doesn't easily break, and I don't lose messages due to losing UDP packets over a busy LAN. I can also take advantage of PROP automation and lots of other free VM goodies to help manage the system. Does that help?
Re: Spool
YES IMMENSELY. Linux guests are our sole customer on /VM, so that is where my 'need to know' lies. Good. I have a personal interest in making sure BCBS gets this right. 8-) One other observation on DCSS: these are being exploited for Linux as containers to use for seldom-changed filesystems that are mounted on lots of systems. Mapping the contents of the filesystem into a memory block, and then mapping that memory block into multiple virtual machine's address spaces is really really clever, if a somewhat of a bear to manage. Great for /usr on mostly-identical systems, though. I'm sure this wheel has already been discovered: Is there a 'doc' on using spool and a central 'syslog server' to capture Linux guest console logs? I think I did a presentation on it a few years back, which I can't put my hands on right now. I'll root around and see if I can find a copy. Basically the idea is threefold: 1) spool the virtual console of your Linux guest to another machine that acts as a collector for the files and processor and have it automatically close the console file every 750-1000 lines (or however much risk you're willing to tolerate). 2) configure /etc/syslog/syslogd.conf on Linux to log everything to /dev/console 3) Run PROP plus a homebrew exec in the collector machine that wakes up when a file arrives in it's virtual reader, reads it and sends each record to your central syslog server via UDP (or however you want them archived). Repeat forever. If you get an error in logging, save the incoming file and reorder it for later processing. Very easy, and quick to do. If I find the presentation, I'll put it up on the SNA www site and let you know where to find it. - db
Re: SLES10 Client
Do I need a secondary user defined It's not required, but it is a good idea to have somewhere central for all the console logs on your system to go by default, rather than have them scattered all over the spool. If you want to silence the message, change the CONLOG on the CONSOLE statement in the directory entry to any valid userid on your system, or remove it if you want the console logs to end up in CLIENT's rdr. do I need both CPU statements? No. Most guests seem to feel healthier and more responsive if you have more than one logical CPU, but it's not required or desirable in some cases. Do note that there are some applications that don't build properly in a UP system, so we put the extra statement in to try to catch that. As Rich said, it's an example. Tailor it as you see fit. 19F and the disks you plan to use to put the Linux system on are the important bits. The rest is as you like it.

I'm looking at bringing in a smaller, newer, IBM mainframe and trying to save some money on my IBM monthly license fees. But, I need to support an old guest running OS/390 V2R8. I can't afford to upgrade all the third party software that this guest is using. Assuming that the release of OS/390 can deal with whatever disk and hardware you will be running it on, and you have standard CPs available, then it ought to work OK. Don't expect it to work with newer disks, OSAs, etc - you will probably have to isolate it as much as possible from the real hardware using minidisks, VSWITCH/gLAN, etc.

Re: LOGONBY
So the only thing you are buying here is that you keep TCPMAINT password secret is that the whole idea behind LOGOnBY? So then you only add certain user ids to do LOGONBY for this user id correct? Think of it more as a role: you are assuming the role of TCPMAINT, using your own login credentials to validate your claim to the role. The idea is minimum privilege; shared ids should not be directly logged into, because you lose the audit trail of who did what. You give individual ids minimum privilege (essentially with the combination of LOGINBY and PROP, there's rarely a real reason for any individual id to have more than class G), and they authenticate to the shared ID when they need to do something more powerful, or an extended string of things that require privileges or access to files w/o having to jump through a lot of maintenance-intensive hoops.

Re: z/Linux Network Monitor

Re: Partially Successful: OpenVMS on System z
I didn't know that OpenVMS could run on Intel Itaniums, but it sounds way cool. Yes. It's a relatively recent development (and about 20 years too late -- we could have been spared Windows entirely if DEC had bought a clue way back when...*sigh*), but it's actually fueling a renaissance in VMS usage. VMS is a nice, tight, secure, easy to manage system, with decent batch and tape processing capabilities, and excellent compilers and compatibility with the IBM extensions for COBOL, a decent CICS replacement, etc, etc. It's a terrific replacement for small VSE and z/OS shops who can't get an affordable z system these days. HP doesn't seem to have such a huge problem with hobbyist use, either. Now if someone would port REXX to VMS instead of DCL... hmm. Now that's a useful thought. What's next, Mac under z/VM? :-) TOPS-20, of course. If I say fiat lux, then I expect the OS to turn the lights on reliably, with a proper Emacs for editing the universe's config files. Galaxy on Z -- it's about time we got a decent batch system for Z. *grin* 8-) Actually, if this emulation approach we're using for the Alpha works out as it appears to be doing, PPC operating systems like AIX and i5OS would be a logical next step.

Re: SPOOL/PAGE and cylinder zero
Historically, there was a problem, and that was a required restriction in those days. Modern CP does handle it correctly.

Re: IUCV - What's wrong with this picture?
1. Does IUCV infrastructure overhead specifically associated with number of connections become prohibitive at some well known point? There is a limit to the maximum number of connections (a parm on the IUCV statement in the directory entry; I think the max value for that parm is 64K, but check your docs -- I don't have manuals with me at the moment). 2. Has anyone had experience with an application having a high IUCV connection count like this? If so, what was that experience? Probably the best example I know of for an application that uses a lot of IUCV connections is the VM TCPIP stack (yes, I know there is a lot of VMCF too, but it also uses IUCV.). It seems to be fairly stable and scales well. At a past employer, we had a few applications that regularly had several thousand IUCV connections open and active simultaneously with no connection state related problems. The key problem with performance tuning for those applications was supplying sufficient virtual storage to provide suitable buffers for the connections, and the need to dispatch each endpoint every time you needed to send and respond to a message. Those two things were a lot bigger hit than the IUCV connection and session management processing. Something also to think about is the additional hit of dispatching and routing messages between VM images if you are planning on permitting distributed IUCV (a good idea). That's going to mean some additional work needed from CP to do ISFC, or asking CP to dispatch TSAF or AVS or IPGATE to get the message frame over to the other system. That can be significant.

Re: Isolating one Linux guest in the DMZ
ur z/VM environment currently sits behind a firewall. We would like to allow one Linux guest to act as an Internet server. We do not however want to expose the other Linux guests or the z/VM environment itself to the outside world. We are using VSWITCH. Good. That makes a few things possible. Is this possible? What options are there? Do we require a separate OSA for the Linux guest in the DMZ? Not necessarily. The easiest thing to do is to have your network guys engineer a new VLAN, and move the guest you want to expose onto that VLAN. That requires no physical hardware changes, and the networking guys can do all the routing that needs to happen outside the box. As long as there are no other network connections to the exposed guest, you can't get from there to any of the other guests. The assumption is that you're using VLAN-aware VSWITCHes, and that your networking guys understand how to make the magic connections to create and propagate a VLAN in your network. These days, that's a fairly safe bet. If you have spare money or excessively paranoid security weenies, you could get another OSA and dedicate it to that one guest. It's a waste of money, but technically valid. As I'm not a comm's guy, please keep it simple. Thanks in advance. You'll want to work closely with the network guys.

Re: Linux Commands
That's going to be complicated because every program you install becomes a new command, and some commands could be books all to themselves. There's also the complication that there are several variations to how documentation for Linux commands is prepared and maintained. All packages are *supposed* to include man pages, but that can be a bit spotty for some of the commands maintained by smaller groups or individuals. The man command will display summaries for each command and details. Some commands use the info command, and some supply HTML pages (which I personally detest). Example: 'man ls' will display a manual page for the ls command. If you're not sure of the exact command, try 'man -k' and a keyword, eg 'man -k mail' will get you all the commands that contain the keyword 'mail' somehow. The commands that use 'info' (usually things originating in the GNU project like GCC) work with similar syntax, but they bring up a full screen browser to navigate the documentation. Info tends to be used for more complex applications, like emacs. The emacs documentation is a full-scale book of it's own. Your best bet is a good Unix book like the O'reilly sysadmin guides.

Re: OSA Adapter TCP/IP stack association limit?
Does this approach get around the stack limit some way? If we try to put 800 machines on a VLAN, will this blow the limit referenced below? The layer 2 TYPE ETHERNET VSWITCH gets the OSA limits out of the line of fire entirely -- the OSA(s) (note multiple) servicing the VSWITCH just forward frames, acting like a bridge to the VLAN. You can put lots more than 800 guests on a VLAN. I know of people with well over 2000 guests of various types on a single VLAN sharing a VSWITCH. Downside is that unless you have a z10, I don't think you can have a OSA card in layer 3 and layer 2 mode simultaneously, so you can't share a card with a LPAR that requires layer 3 mode. Probably not a big deal for you, as you're likely to push the limits of a card and not want to share it anyway, but YMMV. The limit applies only to device triples directly attached to individual guests, which is a not so hot idea under VM anyway given that VSWITCH exists. It'll also simplify the ability to move virtual machines if IBM ever gets us such a thing -- not tying the adapters to actual physical devices is a Good Thing.

Re: R.I.P -- BookMaster.....
We still use BookMaster 1.4 here to build documents we distribute to clients and such. I think it's about the best way ever for doing computer related documentation of most kinds. Me too. Doc tools written by people who actually have to *use* them. Best system I've seen. Wonder if we could ask the current product owners to put these tools up on the VM download web page, for use as is, where is? I would rely like to be able to use ProcessMaster here as well. Second the motion. Anyone know who the current product owner is? It'd be a good place to start begging.
Re: SMAPI Java library?
There are already Java libraries to front-end Sun RPC, so that would be one way to go about it. You'd have to feed the RPC stubs to rpcgen to get a proper mapping for your system, but that's not unusual behavior for Sun RPC app interfaces.

Re: Curiosity question: 370 Accommodation Facility Definition
I don't know about running a guest operating system designed for a 370 machine like MVS or DOS/VS. I think you would need SET MACHINE 370. Very likely. Also keep in mind that most of the 370 mode support in the processors themselves is gone, so SET MACHINE 370 might not work at all. Hercules in a Linux (or OpenSolaris) guest would be the way to go if you really need MVS 3.8 on a z10...8-)
Re: CSE and VMSERVx
I think it is reasonable to use VMSYS and VMSYSU in the same manner that IBM uses them in the 'default' RMSMASTER configuration. For applications that are LOCAL to this system, I put control type information (config files) i n VMSYS and use VMSYSU for work and logfiles. At disaster recovery, I do no t mind starting with an empty VMSYSU. Given that IBM discourages use of the VMSYSx: pools for real user data, would it make sense to propose that those local filepools be configured in a way that they reflected the node name they were running on, eg. if running on node FOO, then the default install would create FOOS: (for the IBM uses like RMSMASTER if that code can't be fixed to not require VMSYS:) and (optionally) FOOR:? Using a generic name like VMSYS: seems to be both confusing and not really all that optimal. If one wanted to provide a default pool for user data in the starter system, how about calling it node:, eg FOO: from our above example. It shouldn't be too hard to have the SFS code determine the current node name and publish that as the filepool name and/or APPC resource name.
Re: PIPELINES and Deblocking
I don't know why Unix used NL (==LF) instead. Perhaps a different har dware device? One reason (probably not the only one, but one): Bare CR on the model of DECwriter commonly shipped as PDP-11 console terminals tended to foul the ribbon, especially if you issued it from 40 character positions into the line. LF pushed the ribbon down into the holder (side effect: making it harder to foul the ribbon), and there was a switch on the DECwriter that would auto-add a CR to a bare LF (not the other way round), which saved a whole character frame on a 110-baud console terminal. BSD 2.x used LFs to try to optimize for that. Dunno if V6 or V7 inherited that weirdness from the PDP6 or not. The PDP6 at SAIL didn't have that problem (only a few DECwriters left by the time I got access to it, and NOTS didn't care). All the -11 DECwriters would jam if you ran 300 baud on the console.
Re: SUSE Linux Enterprise Server 10 SP2 Starter System for IBM System z
Samples are just that, samples, not Holy Writ from ${DIETY}. You can,
of
course, choose to do anything you like.
Well, as the author, I rather like the idea of saying let us turn to
chapter 2 of the Gospel of Installation... 8-) YMMV.
The idea with the 15x separation was to have a small /boot separate
from the bulk of the other parts, and encourage the use of a separate
/home. The setup in the sample is the base we use for most of our
installs, and it's proven to be fairly flexible for different purposes.
What we're trying is to establish a set of basic conventions on how
things are done that start from field-tested practice. I don't want to
prevent you from doing whatever you want, but the default should be
usable for reasonably large ranges of useful.
Whenever possible, I prefer to have those two volumes only be used for
the
operating system itself. Any add-on products, such as WebSphere,
etc., or
applications, would be installed in separate file systems created from
a
different LVM volume group, using different physical volumes.
This is good practice in any case. The default setup works well with
this philosophy, and it's common good practice in the Unix world.

Re: SUSE Linux Enterprise Server 10 SP2 Starter System for IBM System z
We have a one year contract with Novell until May 2009. They gave us a unique activation code. They told me to download the CD1-CD2 disks from their site. Can I use the SUSE Linux Enterprise Server Starter System for System z to install it? I'm confused... Maybe this will help: The starter system is a prebuilt installation server that you use to create other virtual machines - it contains the disk1 and disk2 images plus a copy of SLES configured to act as a NFS/HTTP/SMB/FTP server to make that data available. It's the functional equivalent of downloading the CD media, setting up a server to provide access to the media, and configuring all the software you need to provide access to the media -- condensed into the single step of downloading the starter system and installing it. You use the installation server as the source to create new virtual machines. Machines that are created from the installation server get the activation codes, because once they're installed, they interact directly with the Novell servers to get updates, etc (unless you set up a local service mirror), and thus need to identify themselves as valid recipients. So, to answer your question -- yes, use the starter system to install a new guest, and when prompted, give it the activation code you got from Novell, and the end product is exactly the same as if you had downloaded the media, found someone to serve it up to you over the network, transferred the boot files, made a boot image, booted SLES from reader or tape, and answered the prompts. You just save a bunch of steps, you don't have to convince anyone to stick a CD or DVD in their machine for two or three hours, and get your virtual machines installed at memory-to-memory speeds instead of just Ethernet speed. All you do is create the new VM userid, LINK NOVSTART 19F 19F RR, ACCESS 19F R, and type SLES. From that point on, you're in the normal SLES installer.

Can I somehow, and I haven't completely read through the Starter Set documentation, download the SLES-10-SP2-DVD-s390x-GM-DVD1 and 2 .iso images and serve them using the NOVSTART virtual machine? The SP2 starter system contains the entire SP2 DVD image already set up for this purpose. If you set up a SP1 starter system, just use a different userid for the NOVSTART system -- there's nothing in there that cares about the userid it's installed in -- and use that as your new install server. That way you don't mess up anything that already works, and you can easily switch back and forth for production use w/o breaking things.
