Re: Removing SSL Support From z/VM 4.4
We have a z/VM 4.4 system which was setup to use Sine Nomine's Linux guest to provide SSL tn3270 support. It has broken, and I would just like to remove the feature so that z/VM TCP/IP would just use regular tn3270. What version of the guest? We have maintained it over time, so if you've got an old one, you may want to upgrade. Where would I find the directions to remove the SSL function? TCPIP Administrators Guide.

Re: Removing SSL Support From z/VM 4.4
I didn't think you guys were still maintaining it for the older systems (z/VM 4.4 on MP3K). We sure are. We just aren't doing one for the new systems that no longer use the Linux-based SSL (because, well, they don't use it). It still can't fix the basic scalability design problems with the early SSL code (OCO, anyone?), but the newer versions are a little lighter weight for what it does. You can still get support, too. --d b
Re: BookManager format softcopy
The key trick to getting around this with PDFs is to have access to a full copy of Acrobat and regularly run 'pdfindex' to generate an index file for all your PDF documents. You can give that index file to the PDF reader, and your searches will work more like the Bookie ones (cross-book and intra-book). I'd distribute my index file, but pdfindex generates a file with absolute paths in it, so you'd have to organize your books the same way I do for it to be useful. -- db From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Jonathan R Nolting Sent: Tuesday, September 07, 2010 1:44 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: BookManager format softcopy I agree.

Re: BookManager format softcopy
More feedback (1 = gotta have it now, 4 = when you have a lot of free time) - TOC simplification and consistency (avoid useless divisions of information) 3. We're used to it by now, and the PDF manuals don't really exhibit this problem too badly. - PDF bookshelf and search enhancements 2. - Better education within the context of the Library on how to effectively access it with available tools. I mean, I had just learned about the Advanced Linguistic Plug-in a few days before Michael Forte and others posted on the subject.. Who knew? 4. Stop inventing custom tools for this. Stick to common stuff like PDF and ePub. Everyone else has. - A Linux version of the Information Center 4. If you must. BTW, there is a open-source Linux version of pdfindex. - Better bulk packaging of the Library so that it is easily moved around. 2. A write-locked USB drive or SD card format would be handy. A 32G SD card will hold the entire z/OS and z/VM (and most of the z/VSE) libraries (recommended accessory before you go out in the field, Alan...). - New formats for mobile and e-book devices. There oughtta be an app for that, eh? 1. There are very good PDF and ePub readers already out there. - Tools to transform BOOK files into reasonable PDFs, even if only a meager EXPORT function in BookManager READ.

Re: BookManager format softcopy
Sounds like a plan. I'd actually omit the Information Center docs too -- they're almost impossible to use, really. The z/VM Information Center and PDF files would still be produced.
Re: BookManager format softcopy
I'm curious. I have a KindleDX expressly so that I can easily read PDF books which are US Letter or A4 sized. Given the upswing in other, smaller, ebook readers (and things like iPod touch and smartphones), would a mobi format be useful? ePub format would be generally about as helpful as PDF, and it's better behaved on the smaller devices (eg, iPhone/Android, etc). The mobi format would probably screw up the railroad-track diagrams something awful. If you can create PDF, creating ePub from PDF is pretty simple. Or perhaps even a PDF book which is formatted to A5 size instead of A4? Or, heavens!, even publish the documents in Linux docbook format and let us create the book in whatever format we like using docbook tools. OK, this last is likely going too far as IBM starts to lose some of its control over content. Bookie source used to be available for some manuals. Or if you have the .BOO and Bookmaster/READ, you can produce the source with a few contortions. That's how I converted the VM/XA docs to PDF. Rather than Docbook specifically, how about SGML? That would still allow formatting with SCRIPT if necessary (DCF can handle SGML docs) and also allow processing with Docbook if IBM made the DTD available... -- db
Re: BookManager format softcopy

Re: BookManager format softcopy
With regard to your mention of PDF search capability, have you downloaded and tried the IBM Advanced Linguistic Search Plug-in for searching enabled PDFs and across PDF extended shelves with the same (or nearly same) search quality as BookManager? PDFs don't give me problems. It's the Info Center stuff that makes me want to chew nails. I have the full Acrobat package and I just index the PDF documents and I'm done. No muss, no fuss and it just works. Regardless of platform, connectivity or what release of Java I happen to have on the machine in question. Which none of the other formats can claim, BTW. With regard to the information center, the biggest contributing factor to the organization of the content is that the z/VM library is organized using a book methodology and not broken down in such a manner that lends well to article based documentation (the information center is article based). I know those who work on the z/VM documentation are continuously improving the organization of the documentation and have the desire to improve the user experience. Just takes time with so few hands. To be blunt: don't fix it. It ain't broke. Article based docs are inordinately hard to use unless you have the same mental map as the author. I have yet to find anyone else as demented as I, so that's pretty hard to do. Aside from that, there are newer versions of the Eclipse subsystem -- that drives the heart of the information -- that we continuously evaluate and migrated to. These newer versions improve the functionality and speed. None of that will fix a basic disconnect in how people use the docs. It's just lipstick on the pig. This biggest benefit to producing information centers is that the content can be updated much quicker and more easily. If we can round the infrastructure bend then enables that, we might see the end of the days where to use version X release Y of a product one needs to read the release specific documentation, APAR documentation, and possibly a subsequent release documentation (all because updates are not easily made between releases or as service is release to the service stream). Ugh. I WANT release-specific docs. You released it at a point in time, and the docs should apply ONLY to what you released. I don't want to figure out what you've added since you released something - we already have that problem on your other platforms, where the same problems noted above apply. (PERSONAL OPINION) Some exciting functionality I'd like to see in the future involves commenting and user contributed documentation. After all, the users really know the product and what others would look for the most. If you'd like to see a newer implementation of an information center, navigate to the IBM Ration Team Concert information center (http://publib.boulder.ibm.com/infocenter/rtc/v2r0m0/index.jsp). You'll notice the organization is much different and the load time is less. The last thing I want is other people writing in my manual margins. It's hard enough figuring out what YOU meant, let alone random yutzes who we don't know at all and have no way to evaluate whether they know spit or not. User contributed docs are what Redbooks are for, where they get some sane editing and some fact checking done before you put your logo on them. -- db

Re: Duplicate VOLID's
I’ve always liked Vn, where n is the order of acquisition in your organization, eg V1 for the first volume acquired, V2 for the second, etc. The V is there to not confuse commands that need a volser as input into thinking they’re dealing with a real address (once had that problem with a system that had all numeric userids --- ick), and I’ve never rolled over within the same complex during my time there. If you stick to decimal numbering most people don’t confuse them with addresses, and if you go through a lot of disks (as I assume Visa does), you’re still unlikely to replace 99,999 at a time. Works with LPARs, VM, z/OS, pretty much any situation you come to.

You should also check out using PVM (and the associated PVM gadgetry) as your target for the DIAL command.

PVM was designed to handle very large numbers of sessions and deal with dialed terminals.

Mark's question was WHY are you building from source? Why not use the pre-built code that came with your distribution? One common reason is that AFAIK neither distribution yet builds the necessary components for autoassigning uid values if you are integrating a Linux system into an AD domain using winbind. The source is there in the source RPMs, though - it's a lot simpler to make it from that instead of the source tarballs.

But, We also have here, the VM Performance Tools, and now, the boss here, ask, if is not possible get a report from this Product, and if this is better. Perfkit is a lot more sophisticated, and it certainly supports far more statistics than just CPU usage. It also uses a more system-friendly means of collecting the data (via the system monitor services). So, We are putting this question here for apreciate by gurus VM, and , see what is the better. If someone understand that VM Performance Tools is the better, have a way for us extract data from there? All Perfkit-collected performance data is written to files, which are available in daily, weekly and monthly summary form in CMS files maintained by the PERFSVM virtual machine. The record layout is documented in the Perfkit manual. If you have 3270-graphics compatible terminals (or GDDM) you can produce very nice graphs and reports without writing any code at all. It also has a WWW interface that's pretty nice. I would suggest using Perfkit. It's not perfect, but it's a lot better than do-it-yourself methods, and somebody else supports it. It is also SFS friendly, so you can access the SFS directory while it's running, and do your custom reporting if you can't get Perfkit to do what you want.

The question in my mind is whether the last cylinder of the pack is actually in use and/or whether the filesystem could be resized online to be 180K smaller (so as to free up the last cylinder). DDR is smart enough to be able to relocate the disk image (eg, restore it to cyl+1 on another disk), but that won't fix up any internal references to the filesystem size or LVM magic that might be there, and you will get Weird Failures that you really don't want to try to track down. If it can't be resized or is part of a LVM, then you're SOL on that solution. Ultimately, if you want to keep using DFDSS (and I'll point out that you have been EXTREMELY lucky if you haven't had failures of your backups) the solution is to allocate a new pack with a proper VTOC in cyl 0, and follow the instructions on linuxvm.org to migrate the filesystem from the current disk to the new disk. Short of that, you'll have to use DDR for those two packs (if you use CMSDDR, you can store those two disks as CMS files on one of the other packs, and then restore them back to real DASD from there). That's probably the only way you'll be able to do this quickly enough for your DR test.

Re: z/VM OSA with z/OS guest
If you want to stick to dedicating the adapters, you¹ll need to use different real addresses (eg, 7D0,7D1,7D2, 7D3, 7D4, 7D5, etc), but dedicate them to the same virtual address (eg 7D0, 7D1, 7D2) in the CP directory for the zOS guests. In the directory for z/OS 1: DEDICATE 7D0 7D0 DEDICATE 7D1 7D1 DEDICATE 7D2 7D2 (the easy case). In the directory for z/OS 2: DEDICATE 7D3 7D0 DEDICATE 7D4 7D1 DEDICATE 7D5 7D2 (z/OS 2 still sees addresses 7D0-7D2, but the real hardware uses a different OSA triplet so everyone plays nice). Do the same with z/OS 3. If you¹re willing to experiment and get a MUCH niftier way of doing it (dedicating devices is SO old-skool z/OS... Sniff), use a VSWITCH. Define the VSWITCH with real device 7D0 as the real device in DEFINE VSWITCH. Grant ZOS1, ZOS2, and ZOS3 access to the VSWITCH. Then in the CP directory use NIC statements for 7D0 connected to the VSWITCH. Slick, easy to manage, and MUCH more flexible in how you use the hardware. At current time, I have each z/OS guest with his own triplet of unique OSA addresses. Each one will work fine UNTIL they are all up and running, at which time, we start seeing ³console hangs² and what appears to be machine lockups. Some times they will eventually clear themselves, sometimes not. And it rotates as to which z/OS guest system hangs. This sounds more like resource exhaustion than a network-related issue. Look at the recommendations for system resource management sessions that are in the Linux guides and in the running guest OS manual. A lot of the problems are similar (but zOS is even more ill-behaved in some ways).

Re: Second screen in a z/VM CMS session
I'll second what Mike said about TRACEXEC. It's a great tool. It's not going to do what you envisioned originally as far as working with two screens, but you should consider TRACEXEC anyway. If you do go the two-userids-with-SFS route, also consider SESSION. It allows you to log into one userid, run SESSION name PFx, and then you can switch sessions with a PF key. You can have lots of named sessions, each on a different userid. Again, not exactly what you wanted, but enormously handy for those moments when you need to check something on another id without having to start a whole new session.

Re: Issuing VM commands from z/OS...
AFAIK, there's still no IBM-supported way to do this. VSE put the VM interfaces in ages ago, but they've always been a bit smarter about playing nice with hypervisors. There's a nice mod on the SHARE mods tapes that teaches JES to CP CLOSE spool files via DIAG 8 and also provides a utility that will do CP commands read from a input dataset, also via DIAG 8.

Re: I hate to ask -- VM passwords authenticated against AD?
I have most of the piece parts done (IUCV driver, PAM driver, Kerberos and LDAP interfaces, Linux guest to do the heavy lifting) to enable VM to use any authentication sources supported by PAM, including AD. The remaining part is the necessary CP modules to normalize all the entry points to CP into a documented interface that doesn't require rebuilding CP, then convincing IBM to either ship VM with the RACF interface modules prebuilt, plus a dummy RACF lite that implements the defaut defer behavior, or agree on what the external interface should be in terms of service access points and ship that. I'd actually donate the service code if IBM would accept it. As you might imagine, the last part is the hardest. If someone wants this badly enough to pay for it, then I can probably have a beta-ready version available in a month or so. -- db
Re: I hate to ask -- VM passwords authenticated against AD?
In this case, however, both IBM and CA offer products for sale in this space. I would rather see the requirement levied against the various ESMs to provide this function since that's where it logically belongs. Alan Altmark z/VM Development IBM Endicott I'd make a counterargument that if IBM intends to position z/VM only as a Linux hosting environment, then the current setup that requires the user to have the skills to rebuild CP to enable an ESM (which Chuckie usually recommends) is highly user-hostile, and needs to be resolved at the CP layer, not in third-party products. Every ESM shouldn't have to invent the CP interface wheel. A cleaner, less intimately entwined, set of security interfaces would be good for everyone, including the IBM products, and with the enormous amount of work going into z/VM 6.next, this would be a good time to architect it in. The rest of the functionality (resolving userid validity, credential mapping, etc) are all user-space pieces, and I'd totally agree that that's where they belong -- in the ESM logic. But, that's the issue I mentioned. If there's consensus that this would be useful, and if IBM would consider adding it to z/VM, I'm willing to do the work. I just don't want to create Yet Another Way to do it, which perpetuates the current situation.
Re: I hate to ask -- VM passwords authenticated against AD?
When building an ESM, you have some fairly complex challenges. At the top of the list, the ESM 1. Cannot be simply or easily circumvented (even by a sysadmin [as opposed to sysprog] ), 2. Must enforce a limited set of operations when the ESM server is down sufficient only to get the ESM server back up and running or to declare The ESM's dead, Jim. 3. Must recognize and differentiate system initialization activities from 'steady state' stuff 4. Must generally support the idea the CP is the enforcement point. Policy may be derived from a server, but CP is where the Real Decisions are made and where it is understood that, sometimes, the policy does not apply or is a Really Bad Idea in some cases. That's impossible to do if all the logic is in the server. Something tells me we're actually agreeing with each other but using different words. I'm not arguing against any of those points. I am arguing that the current implementation makes implementing code (both for the programmer and the user) that exploits the existing interfaces unnecessarily complex (and release dependent), thus increasing everybody's cost of operation and ownership. I'm arguing that we don't have to reinvent that consolidation piece to present a way to connect a ESM to CP. But, never mind. Just an idea. If somebody wants it, they'll holler. -- db
Re: Automated Logoff of CMS user

Likewise, one must accept the valid ones. Wisdom is knowing the difference. [With apologies to Dr. Niebuhr.] I tend to fall into the discretion is the greater part of valour camp, but again, YMMV. I guess I've reached the point in life where crusades are less fun than they used to be. No, key lock is not reported, being a completely local phenomenon. I was thinking along the lines of the host causing the emulator to enable the workstation's (or its own) lock program just by sending a special order or structured field. When the user types a password, the data flows back to the host for validation. Kind of like an http challenge. It would have to be inside the terminal emulator itself. Screen lock in most desktop systems is separate from individual applications and you wouldn't have the ability to modify/trigger it. Too bad about the key lock. That would have been elegant. VM -- just turn the key. Of course, VM's ability to disconnect the session from the virtual machine accomplishes the same thing, but it's rather heavy handed.

Re: Automated Logoff of CMS user
This may have been asked before but I was wondering the best way to Automatically log off a CMS user after a designated time frame. This is to address an Audit finding. If your users log in via tn3270, you can use idle timeouts in the TCPIP virtual machine to kill idle connections, and let the CP READ time bomb take care of it. Otherwise, if you have PERFKIT or something similar, there is a idle timer in those products where you can use the information gathered by the performance monitor to determine when a user has been idle for a period of time, and take a useful action (eg, detach devices and then force them off).

I just have trouble with a policy that says After a CMS user has been logged on for [n] minutes, log them off. To what end? And is it really only CMS users? In Linux systems the CMS users are the admins and SVMs, none of whom should be logged off (IMO). (I might buy FORCE DISC, but not logoff.) Many orgs have a policy that unattended sessions be automatically terminated after X minutes of inactivity, regardless of OS. Most if not all US govt agencies have such policies. For other OSes, that means logoff (or equivalent), since most of the other OSes don't have a disconnect/reconnect option (other than using screen...).

Things have progressed somewhat since then and a properly mandated and managed end station screen lock will suffice. Depends on the auditor. For some, it will. For others, it won't. YMMV. I say somewhat since I think that the 3270 datastream is ripe for the host to be able send an enable/disable/query screen lock to the emulator, independent of any OS-level locks, and potentially appropriate to the specific application. (Some apps access more sensitive data than others.) I don't remember -- is the state of the key lock reported? If so, you could probably overload the screen lock state onto that 3270 state without having to reengineer stuff.

Unsure if the printer would accept a usercode via a PCL or postscript command. If so, then you could add it via the prefix eparm. If you're willing to set up a Linux guest between RSCS and the printer, CUPS has a concept of an instance, which is basically a package of options for a particular printer.

Re: HiperSocket UCBs
Create a Linux guest as a L2 bridge between a VSWITCH and the hipersocket. Only one HS UCB used, and you still get separation. You can use VLANs to separate traffic.
Re: HiperSocket UCBs
Are there any performance implications with doing it this way as opposed to HiperSocket directly to each guest? Yes - I'll leave it to others to quantify it exactly, but it will use a non-zero amount of 390 CPU to do the packet forwarding between interfaces. Since there is no external connection to the hipersocket, you can't offload the routing or switching to a non-390 CPU. (Another reason IBM should have convinced Cisco/Nortel to produce a bus-attached router similar to the chassis router module they developed for the BladeCenter to put in a Z. ) Another option is to use a dedicated 10G OSA for this traffic on both LPARs and connect the two physical ports to an external dedicated switch. That has a much smaller internal CPU overhead, but it's certainly not cheap. The CPU used to drive the adapters and do the data moving is accounted against CP, not a individual virtual machine, AFAICT. Hipersockets (and any attached device strategy) doesn't work well for massive scale. You just can't install enough of them for a big farm, so you have to start using virtual tricks. You're probably on a z10, so here's another idea - try defining a L2 VSWITCH using a hipersocket device - I faintly remember reading somewhere that hipersockets got L2 capabilities at some point. I don't know if it'll work(never tried it), but if if will, then use that instead of individual UCBs attached to guests. Define 2-3 UCBs to the VSWITCH just in case (although if a HS device fails, you're already in deep something), and use VLANs to separate the traffic. n Db n

Re: MTU on Hipersocket
We just found out that the defined MTU's differ, and I always heard that MTU sizes should be identical: Unless path discovery is active on both ends of the link, the sizes should be identical. Might this be an explanation? How comes it works fine (most of the time) with apparently different MTU values? Nothing sent a packet big enough to cause one end to need fragmentation, so you got lucky. It broke when you got a very large packet that needed to be fragmented, Path MTU discovery was off, and the sending side kept trying to send and got rejected. Since you're running DRDA, that would be an easy scenario to do, since the results of queries would be different sizes.
Re: Ok, I'm confused now...
You forgot that the LPR *client* doesn't use port 515, but ports 721- 731, inclusive (per RFC 1179). The SECURE=NO recommended by others eliminates the need to reserve those client ports for RSCS. D'oh! Thanks, Alan. My mind is going. -- db

No. Here are the parm statements: LINKDEFINE VA1P8 TYPE LPR FORM * AST PARM VA1P8 EXIT=LPRXPSE HOST=192.168.101.17 PRINTER=va1p8 These worked with 4.4 on the same host, no changes in the print server or firewall settings. Will try SECURE=NO, though. I thought the PROFILE TCPIP entry was the key to not having to mess with SECURE=NO? n Db n Can you post the RSCS LINKDEFINE and PARM statements you coded?

What I have been doing up to this point for a new z/Linux guest build is, not necessarily in this order and does not necessarily include all steps but, Crave out the DASD for the z/Linux guest Init the DASD using CPFMTXA putting a label on the disk Setting up the Directory entry for the new guest, which includes specifying the MDISK for all of the DASD for the guest. Unless you are giving the guest the real cyl 0, you need to do the format for at least real cyl 0 with ICKDSF (what CPFMTXA runs under the covers) to put a real volume id on the pack. I find that even if you are giving the guest the real cyl 0, the extra step of running DSF on the entire real volume eliminates any past uses that may confuse system operation later on (think about what would happen if you accidentally gave a guest what used to be a VM paging pack, and forgot to clip the allocation bitmap to remove the page space. Bad Things Ensue. Kickstart and VM paging space are NOT compatible. Things Go Boom. Trust Me.) So, if you are giving the guest the full physical volume, you don't HAVE to do the DSF run, but it's an extra safety measure that it doesn't cost much to do, and you'll be grateful for if you ever need it. If not I assume then I would replace the MDISK statements in the Directory entry with DEDICATE statements for each one of the DISKS. We do not share DASD between guests here so what is defined to the guest belongs to that guest only. Is there anything to be aware of by changing to DEDICATE statements from MDISK statements? DEDICATEs tie you very firmly to specific physical configurations. Does your DR configuration have exactly the same device addresses for real devices? If not, then you'll have to update the directory when you move to to DR vs just changing volume labels which aren't bound to specific device addresses. You can do search/replace in both cases, but it's a lot easier to relabel packs when you restore your stuff on them than have to screw around with addresses, especially if it's a REAL emergency and you may not get your normal DR configuration because of a sudden influx of companies needing DR. My only concern is with the DFDSS backups that I do on the z/OS for the guests. I am not sure if it matters or not to DFDSS whether the pack was initialized via CPFMTXA or z/Linux during the kick start process? It shouldn't, but why introduce another variable? CP and z/OS have been getting along well for decades now. It's a one-time step, and it doesn't take that much longer. You can also shortcut the process (if you have Flashcopy) by keeping a blank formatted volume around, flashcopy it to the new disks, and then just run DSF on cyl 0 to relabel the pack. That's almost instantaneous, and you get the best of both worlds. -- db

Alas, without RSCS we have no NJE connections to z/OS for situations where we'd like them to TSO TRANSMIT (for example) files to us. Having them use FTP to a VM's reader would work, with the big downside being the exposure of a VM userid and password in the process. The transfer process would be greatly simplified if something on z/OS knew how to talk to UFTD. There are other alternatives for TCPNJE than RSCS. -- db

Check the directory entry for MUCOPER and if the CONSOLE statement has the word MUCOPER on the end of it, remove it and log MUCOPER off and on. It will stop spooling it's console, and that file will go away and never come back.
Re: Question aboout DDR Backup Question
Use the pipe-capable DDR, and dump to standard label tapes via the TAP SL stage. If you do that, normal multi-volume tape processing is done, and you specify the volumes in the LABELDEF for the output tape DD. Works well.

David, we have received the following response to your WAVV200904 Requirement, Add SNMP metric retrieval support to VSWITCH User Group Number - WAVV200904 Document Status - Suggestion Title - Add SNMP metric retrieval support to VSWITCH IBM will use this request as input to planning but no commitment is made or implied.

Re: Question aboout DDR Backup Question
It would indeed be nice if IBM or some other vendor would provide a DDR program with full tape label support, but my head got too bloody from beating on that wall 25 years ago. They did. The PIPE-capable DDR lets the TAP stage handle it. Then you don't care about tape length, or label management or any of that stuff.
Re: Question aboout DDR Backup Question
That is the DRPC package (see http://www.vm.ibm.com/download/packages/descript.cgi?DRPC That's it. Thanks, Bruce.
Re: Question aboout DDR Backup Question
For those wondering: Great! But where do I find The PIPE-capable DDR ?... http://www.vm.ibm.com/download/packages/ Except that's not the one I'm referring to. IBM made available a version of DDR that directly supported PIPE input and output. It was a summer project by an intern, and they released it from one of the VM developer pages. It used the standard DDR format instead of the PIPEDDR format. I'll see if I can find the information about it. It was posted to this mailing list. -- db
Re: Question aboout DDR Backup Question
That is the DRPC package (see http://www.vm.ibm.com/download/packages/descript.cgi?DRPC That's it. Thanks, Bruce. So, Attach a tape drive to your id at virtual address 181 (and one at 182 if you want it to alternate drives) Attach the disk you want to dump at virtual address 1FFF (remember, the virtual machine owning the disk should be logged off while you're doing this) FILEDEF OUTTAPE TAP1 SL ( RECFM FB BLKSIZE 8000 LRECL 80 ALT TAP2 LABELDEF OUTTAPE FID ? VOLID ? FSEQ CRDTE n EXDTE n Respond to the FID prompt with a OS dataset name, eg VOLUME.xx.DDR.DUMP.julian-date-for-today Respond to the VOLID prompt with a couple of tape volume names (these are SL tapes, so your TMS should get involved if you have one, otherwise you have to keep track of which tapes you used in some way. Note that if you use CRDTE and EXDTE on the LABELDEF, you can tell which tapes are available by mounting the tape and using TAPE DVOL1 (TAP1 to look at the label information outside of the backups). Then: PIPE DDR DUMPALL DDRIN A | QSAM OUTTAPE Where the file DUMPALL DDRIN A contains: SYSPRINT CONS INPUT 1FFF 3390 SCRTCH DUMP ALL Y (blank line) And watch the fun. For the next disk, update the LABELDEF for the next FSEQ number with the CHANGE operand, and rerun the PIPE DDR step. Repeat for all volumes. Presto. Tape label checking in DDR that works with bare CP or with a TMS, and it won't let you mount the tapes in the wrong load or in the wrong sequence. The same approach works with TCP sockets and netcat on a Linux box, and it's nicely restorable if you run the DDR stream through FBLOCK as well. I wish IBM would ship the DRPC DDR as the standard one. Then all we would need to do is produce a PIPE-friendly SPXTAPE, and presto! Tape free z/VM. -- db
Re: CP's Parm Disks
The real problem is that the third-party vendors do not all comply with the standard. I'll second that. If this is the future strategy, then one of the things that needs to happen ASAP is that IBM needs to aggressively provide education to vendors and users alike on how to package stuff properly to fit in with this scheme. I've tried. It ain't easy, and it ain't well documented, and loaning out Tammy Z isn't a scalable solution. Do a session at SHARE or WAVV on how to do SES packaging. Or if you'll provide an instructor, I'll host it. There's enough folks in the DC area who develop VM software that it'd be worth it. -- db
