For non-encrypting drives (2105 or 2107), perform a TRKFMT ERASEDATA CYCLES(n), where 'n' is set by your own data security people. Each cycle will write 3 different bit patterns. Then delete the array. When you delete the array, each drive will be formatted to zeros. You cannot re-use the drive (DDM) in a new array until the low-level format is complete. On the DS8000-series with the Full Disk Encryption feature, then TRKFMT ERASEDATA is not needed. When you deconfigure an encrypted array, the drives will do the local equivalent of TRKFMT ERASEDATA before applying a final coat of zeros. And just so no one gets too paranoid :-), a track is tied to a physical location in the array. When you write on a track, you are writing over whatever was there before. As discussed earlier this week over on the IBMVM mailing list, this kind of erasure is (obviously?) necessary only when the drives are leaving your physically secure facility. Hosts accessing the drives cannot see residual data after a simple host format operation (e.g. ICKDSF INIT or CPFORMAT, or CMS FORMAT). Any residual data that is physically present is inaccessible.

Perhaps IPL is unaffected by the CCS opcode present in the spool. All user data in the VM spool has carriage control because the only way to get data from a virtual machine to the spool is via a virtual PUNCH or PRINTER. (System data files are excluded from this discussion.) And, yes, the spool contains the CCW opcode and data that the guest (or in some cases, CP) put there. CMS functions such as PRINT and PUNCH generate the CCWs and do the I/O to place the user data in the spool. The only thing that limits the CCWs is the virtual device type. The spool is just a holding area. Generally speaking, punches and printers put data in. A virtual reader takes data out. Virtual punches are limited to 80 characters since VM simulates a 2540. Virtual printers can have a variety of lengths, depending on device type (1403, 3211, 3800, etc.). Virtual AFP printers will accept 32K records if the cc character (machine code) is 0x5A. This is what PSF uses to write LIST38xx files. Because the virtual reader is a 2540, it cannot read records more than 80 bytes. Accessing spool files that contain those 0x5As must be done using the DIAGNOSE 0x14 interface to the spool. IPL from the virtual reader works like IPL from disk, except that CP has to figure out what part of the spool file is data. As long as the CCW in the spool is a data mover (e.g. WRITE), that data will be read in by IPL. If there are any no-ops, they are skipped since they (in the real world) don't exist. Everything in CMS has records, but some processing, e.g. FTP BINARY STREAM, will ignore record boundaries. Everything in the minidisk filesystem (EDF) and in the Shard File System (SFS) has records. The POSIX-conformant Byte File System (BFS) does not. BFS is where you store data when the VM system is simply being used as a data repository.

They provide the code pages and the translations. The GCoC says EBCDIC 0x15 in cp1047 should be translated to 0x85 in cp819 (8859-1), as you say. (The translation table 10470819 on z/VM gives you the GCoC-defined translation.) In the traditional System z world, we store text files as records. In that world, the 0x15 has significance only in device drivers and then, typically only to SCS printers. z/VM keeps the history alive, but I digress The rub is, of course, POSIX. When in a POSIX frame of mind, the 0x15 again has significance, being the IBM-chosen value for the newline required by the POSIX standard. Now and the POSIX translation rules apply. It's an inherent fugue state. IMO, if you use iconv in z/OS outside of USS and explicitly tell it IBM-1047 and IBM-819, it should convert it as you describe since to do otherwise destroys the ability of other platforms to reliably translate the file back to code page 1047. I have a similar problem with the misbehavior of LC_COLLATE=En_US in z/OS LE. IBM is trying to tell me it's an ASCII vs. EBCDIC problem. From a POSIX perspective, collation order should be the same on all platforms. The characters appear in a defined order, without regard to the platform-specific code point assigned to the characters. For example, both En_US and the POSIX locales sort numbers, then upper case, then lower case. This is consistent with the byte sort order in ASCII. They have different sort orders for the control characters, and POSIX only deals with 7 bits.

The good news is that BCPii doesn't (directly) have anything to do with support for the LPAR deactivation (or SIGNAL SHUTDOWN, on z/VM) signal, though it would be a good way to let apps register to hear the signal (HwiEvent, perhaps). The challenge is that the code David refers to uses unpublished details of the SERVICE CALL instruction and the SERVICE SIGNAL external interrupt, so it seems unlikely that MVS will have a published interface for such applications. If z/OS is running as a z/VM guest, a companion CMS virtual machine could hear the signal and use the virtual line mode integrated console to start a shutdown job. When registered for the deactivation signal, there is a delay between the time the deactivation is requested and when it occurs. In an LPAR on a z10, the delay is 5 minutes. If the OS comes down sooner than that, the LPAR deactivates sooner. In a guest, the delay can be specified in the system configuration or directly the commands that generate the signal. And if you tell VM to SHUTDOWN, it will propagate the signal to the registered guests, and delay shutdown in order to give the guests a chance to shutdown themselves.

To get a valid dn, you search() on something unique like mail=user.n...@company.com. Then you bind using the returned DN. Bind() will not do an implicit search(). The set of attributes that constitute a dn are defined by the schema (I can't figure out what to search in the schema to find it, though). cn=my name,ou=place,o=company,c=us is common, but there are others.

No more MFT, nor more partitions, but MVT, then SVS and MVS. IThe more memory you put on the box, the more memory gets used to hold the description of all that memory (metadata). The more demand for memory you put on the box, the more often the OS has to touch metadata and the more of it has to be touched. There are mitigating technologies, but even so there is a point of diminishing returns on memory size. It gets simpler and cheaper to just say create another instance of the OS and split your workload. So now that we have 64-bit addressable memory, does this presage the fading away again of partitioning, of LPARs and create an urge to merge? Same answer.

Re: IFL Extended to OpenSolaris
There is a variety of confusion. Sorry I've been away for so long. Real Life. Disclaimer: I am not a lawyer and am not dispensing legal advice. Rather, I am giving my observation of, at the practical level, How The System Works. Hardware: While you may own the machine outright, you do not own the LIC (the microcode), but have a License to Use from IBM. IBM's obvious (to a layman) intent for the use of the Integrated Facility for Linux is, uh, for Linux. The announcement removes any [IBM] impediment to OpenSolaris on an IFL. Software: z/VM *and all of it's features* (RACF, RSCS, DIRMAINT, PERFORMANCE TOOLKIT) are licensed to run on IFLs in support of that Linux workload. They are licensed under the International Program License Agreement (IPLA) and incur a one-time charge (OTC) with an option to pay an annual fee for service and support. For system software and most IBM application middleware, the OTC is based on the number of CPUs. Sometimes the number installed, sometimes the number you use. (It depends on whether a license manager is involved.) z/VM Co. use the number of installed CPUs. A product that is licensed under the IBM Customer Agreement (ICA) with a monthly license charge (MLC) is NOT licensed to run on an IFL. Why? Because MLC is based on MSUs. There are zero MSUs on an IFL ergo no capacity to run software that consumes MSUs (paraphrasing). You can ask IBM for a Special Bid to give you an explicit license to run ICA software on an IFL. You will usually pay a calculated one-time charge that is indexed to the MLC. The license-to-use may be limited to specific use cases. None of the other IBM operating systems (z/OS, z/TPF, z/VSE) are licensed to run on IFLs and we do not grant Special Bids for them. They are traditional workload. They may serve as clients or servers to Linux, but they do not support the operation and management of Linux or z/VM. We also don't grant Special Bids for things like compilers and databases - things that, again, are NOT in direct support of managing the Linux (and, now, OpenSolaris) workloads on an IFL. We have granted Special Bids for PVM, VTAM, NetView, ISPF and other software that is in support of the system itself. The above are general observations and you may find an exception along the way. The answer yesterday may not be the answer tomorrow. If you have any concerns or questions about a specific piece of software, I recommend you contact your IBM rep or business partner - don't assume anything. Hope this helps.

The above seem to imply RACF and RSCS come packaged in the real z/VM as standard equipment. If this is indeed true, can you verify it and I will go back and request a refund for the last 4 years. You are correct that there is only one z/VM and that it works on both CPs and IFLs. RSCS has been pre-packaged (installed, but disabled) with z/VM for many years, formerly as a standalone product and, as of z/VM 5.3, as a priced feature. When it became a feature, it acquired the IPLA Ts Cs, allowing it to be licensed on IFLs without a Special Bid. When you order Real z/VM, the product includes the priced RSCS, RACF, Performance Toolkit, and DIRMAINT features, but they are all disabled. (The LPR/LPD printing capabilities of RSCS are free and available even when RSCS is disabled.) If you purchase licenses for those features, you can enable them. The evaluation edition does not contain the RSCS and RACF code, however, so you cannot evaluate those functions with EE. DIRMAINT and Performance Toolkit *are* included and enabled. If a significant number of requests for RSCS and RACF are received from people downloading the evaluation edition, we'll certainly revisit the decision to not include them.

Because there's no provision for such in programs offered under the International Program License Agreement. Instead, you're entitled to a refund. But that still means cash on the barrel.

Another example: There is no RESERVE or RELEASE on in the FBA architecture. It is trivial to convert CCHHR to an FBA block number. z/VM, z/VSE, and Linux are able to take advantage of SCSI devices because their file systems treat the disk as a block device. You won't find physical FBA block numbers or CCHHRs in the filesystem interface. File system block numbers are converted to CCHHR or physical FBA block numbers, or memory pages, as needed. But the limitations of the FBA architecture mean that, for example, I cannot share a RACF/VM database when deployed on FBA. Even if CP's simulation of FBA on SCSI was updated to include RESERVE/RELEASE, it wouldn't work because there is no concept of channel path groups and no lockout mechanism in the SCSI controllers.

IBM needs to transition from worrying about protecting z/OS source code to worrying that nobody will want to see it. Having done development in the Linux kernel (for System z) and in z/VM (a mix of source and OCO), having source code is of limited use. If you don't know *why* it works the way it does, the source is meaningless. Over time you can certainly teach yourself *how*, but not *why*. One of the most difficult problems I faced writing the original IUCV support for Linux was the complete lack of professional high-level and low-level design materials, not the lack of source code. And that source code is in C, where the how is more obvious than in my native language (assembler). It just didn't help. And, sure enough, there were later changes in the internal interfaces that I unknowingly misused. Nuances I had missed. It worked, but it wasn't pretty and ultimately to be re-written. Don't read the above as being anti-Source; it isn't, and I'm not. I just I hope it illustrates that source code is not a panacea. For some things it is necessary, but not sufficient. I have a different view of Peter Relson's posts - I think that he is only trying to explain which parts of control blocks are meant to be interfaces and which are not. This distinction has no analog in modern operating systems, where interfaces are expressed *entirely* by APIs and service routines, and not by skipping through PSA-ASCB-etc.etc. Control blocks aren't the problem. Understanding the why's and wherefore's of the values in them is the problem. They're in the same control block, so they have a relationship, but what is it? I think Peter's most important point was that of stability. The more you use with things the author didn't intend you to use, the more risk you add to your system. I think that the clear delineation and respect for application interfaces, product-specific system interfaces, and non-interfaces, has in no small part contributed to the longevity of the platform. Compatibility is not an accident. In any case, I appreciate Mr. Relson's (and other IBMers) contributions to IBM-MAIN, even if I don't always like what they say. Glad to hear it!

Re: Code pages

You can find the most common code pages at http://www-306.ibm.com/software/globalization/cp/cp_cpgid.jsp The PDFs contained therein are copies of the Official Versions maintained by the IBM Globalization Centre of Competency for use by all IBM hardware and software. I've have been running of necessity under the assumption that there is some standard and that IBM's PComm emulator would conform to it, but that is probably a rash assumption. It's also quite possible (likely?) that whatever standard exists may have left some codepoints undefined, and that PComm could have implemented graphics for those codepoints that differ from other 3270 emulators. IBM PCOMM implements code pages that conform to those you will find at the URL above. Those same code pages can be used by z/VM and z/OS TCP/IP apps for ASCII-EBCDIC translation. They are imbedded in LE, too, for use with iconv(). This shows that by PComm's implementation of the codesets that, among other differences, there is an interchange in the graphics for PL/1 Logical not and the Circumflex or caret at codepoints X'5F' and X'B0' between IBM-037-US and IBM-1047-US. It also shows that the differences between IBM-924-Multinational and IBM-1047 are much more extensive than just the Euro symbol, probably because there was no US-specific IBM-924 variant (at least not in PComm 5.6). IBM-924 is the EBCDIC variant of ISO 8859-15 (IBM-923). There is no country-specific version of 924. I believe REXX allows the slash alternative operators precisely because translation with codesets like IBM-037 or IBM-1140 can cause syntax problems and algorithm failure if the caret is used. About 10 years ago I have up on using Logical Not in favor of != or . Not only do those characters work in any code page, they always survive EBCDIC- ASCII translation (e.g. with FTP), and cut-n-paste always gives the correct result.

Many of us are or work for ISVs - especially small ones that can't afford the $100K for a basic kneecapped z9 BC, but could afford the FLEX-ES offering. These ISVs have supported IBM System z and its predecessors for over 40 years. There are many ISVs represented on this list, and the small ISVs have been griping over the perceived lack (and remember, perception is reality here) of a proper IBM response to the FLEX-ES situation for almost a year. Neither Timothy, nor Marcia, nor any other front-line IBMer you regularly see or talk to is going to engage in a discussion about ISVs, PWD, or IBM's future plans for System z. The only people who could respond are IBM executives responsible for those things, and they don't hang out here. IBM deals with 3 kinds of customers: - ISVs - Business Partners - Consumers (end users) [not mass market] Everyone on the planet recognizes that not every ISV can install a traditional mainframe. Even IBMers. We who deal with ISVs or who hang out in places like this appreciate the frustration ISVs are experiencing, but we cannot, as individuals or as IBMers, address them. We are, all of us, waiting to see what will happen. As you might expect, any (non-executive) IBMer who actually has knowledge of the future cannot speak of it. But ISVs should be working through the PWD program to ensure that PWD is representing your needs. The fact that a lot of small ISVs are represented in IBM-MAIN changes nothing since PWD doesn't hang out here AFAICT. Having your livlihood threatened isn't pleasant and your frustration and anger are understandable, but, honestly, you will not get speculation from us on what the future will hold. So if your expectation is that you will get an answer here prior to getting an answer through an official PWD channel, you will be disappointed. Something like this affects peoples' lives and livlihoods and speculation by anyone with an ibm.com e-mail address would be monumentally inappropriate. If we could tell you anything, we would. So please don't take our lack of response here to your concerns as an ISV as a sign of indifference or unconcern. Far from it. All members of the Mainframe Fan Club want you to succeed, but the needs of ISVs are very different than those of consumers, and it is unfair to the consumers to imply that the technology dividends they have received over the last 10 years don't count for anything just because you're unhappy with IBM today. BPs should be working through their channel management to ensure that IBM knows how *your* business is affected. (They don't hang out here, either.) This brings us to consumers. IBM has continued to lower the TCO *and* TCA for the mainframe. A lot. Timothy and Marcia have been trying to respond illustrate those advances. Since IBM is in business to provide value to its shareholders (duh), IBM does have its own financial objectives, too. Common sense says there must exist a price below which IBM, at a given point in time, is not willing to go, and there are sacrifices it is unwilling to make. IBM must, of course, live with the consequences of those decisions, but that's just business. So, if z/OS related middleware software pricing finally breaks the camel's back and a company decides, after a TCO analysis, that the benefits do not justify the costs and that reengineering onto another platform is the right thing to do, then you should do it. We have seen, however, that many companies who take the time to do a careful TCO come to realize that there are qualities of service and capabilities in the mainframe that they have taken for granted. All of a sudden, there are more benefits than originally thought, providing additional weight in the TCO equation. Assuming a company won't push the equipment off the end of the loading dock in a fit of spite, it may decide to preserve its hardware investment and look at Linux on the mainframe. Or not. But with all that said, I and many others sadly recognize that some customers (the consumer kind) are leaving the mainframe. Their IT needs are shrinking, not growing, and it has become painfully evident to both sides that the time has come for a parting of the ways. The capacity and qualities of service aren't needed, and there aren't enough servers to worry about consolidation. If they have benefitted from their relationship with IBM in prior years, hopefully they will remain partnered with us. Some won't. That's just business, too.

If your growth is slower than the technology, that's ok, as we recognize that ever year can't be a Big Winner, but over time growth does need to be present. The shrinking of the mainframe customer base is a cause for real concern. Every time a customer leaves the mainframe it hurts us all.

Re: Running OS/390 on z9 BC
On Fri, 9 Feb 2007 16:20:42 -0800, Edward Jaffe There is no option in z/VM to run a guest in ESA/390 mode on a machine supporting z/Architecture. IOW, if the guest understands z/Architecture, it will issue the SIGP to run that way and there's no way in z/VM to prevent that or hide the fact that the underlying hardware supports z/Architecture. OTOH, if the guest doesn't understand z/Architecture, it should happily run in ESA/390 mode under z/VM even when z/VM itself is running in z/Architecture mode. All boxes, z/Architecture or S/390, IPL in S/390 architecture mode. The operating system must take action to get into z/Architecture mode (SIGP SARCH). z/Architecture is where you get 64-bit registers and PSW, along with 64-, 31-, and 24-bit addressing modes. (Addressing mode does not affect register width.) In S/390 architecture mode (even on a z box!), only 31-bit and 24-bit AMODEs are available and the registers remain 32 bits wide and the PSW is in its traditional form. Naturally, z/VM presents a guest with the same story. Guests always IPL in S/390 architecture mode. If you have a z/VM V3, V4, or V5, running the z/Architecture build, then guests will be able to issue SIGP SARCH and get into z/Architecture mode themselves. If you're running a 31-bit version of CP, then CP has not issued SIGP SARCH and so cannot present z/Architecture CPUs to a guest. SIGP SARCH by a z/OS guest would fail in that case. A system that only understands S/390 will happily IPL, whether native or as a z/VM guest, and begin to run. As a guest, some of the machine Facilities are hidden from the guest and the guest knows not to try to use them. Older guests that weren't aware of such facilities won't trip over their lack. But sometime after the initial IPL is complete, the newly-hatched operating system begins to talk to the I/O subsystem and look around. In an LPAR this is usually where things typically fall apart. There can be chpid types (new cards) he doesn't understand, multiple channel subsystems, different operation of OSA or crypto cards, or indicators that tell him to talk to the I/O subsystem control functions in a different way. choke A z/VM guest, on the other hand, is talking to a virtual I/O subsystem, one that, of necessity, hides much of the real I/O configuration from the guest. CP is ready and able to deal with the real I/O config, but gives the guest a simplified view. So, when in doubt, try it out. But as has already been discussed, the answer to Will it run? and Is it supported? are two entirely different things. Sometimes the enabling PTFs are related to I/O, sometimes to the CPU, sometimes to crypto or OSA. Of course, even if unsupported you still have to pay the MLC if you continue to use the software. Watch out that your current pricing model might not be available on the new box.

Re: Running OS/390 on z9 BC

No. z/VM has to have the needed support for the box. But even if you didn't need a newer z/VM, the guest always sees the new architecture of the box, even if some flavors remain hidden by CP. Subtle differences that are acceptable to, say, CP, might be objectionable to MVS. If an operating system will run on a z890 or z990, it has a reasonable chance to run on a z9. The step from z890/z990 to z9 was a relatively small one. It is a giant leap from z800/z900 to z890/z990.) Even though chpid types in the IOCDS are coded the same way, the cards identify themselves in new ways to the OS. The OS *must* have support for the new card designs because they behave differently. If you don't add support for xxx to the operating system, the OS won't be able to use it since xxx is the only flavor of the card in that box has been heard more than once. We get kind of wishy-washy on our answers about unsupported software because it's ... unsupported. We didn't test it, and we sure as heck won't fix it if it doesn't work, so it's speculation on our part. As everyone knows, we don't like our customers to build deployment plans based on speculation.

Re: What is command reject trying to tell me?

I believe they do not help with problems -- they resolve defects. Had I called them up and said what the heck does this message mean? they would have (politely) told me to go away. I must respectfully disagree. If you had written a program using EXCP and received such a message, such an answer would be justified. Could I have tricked the Support Center into solving the problem? Probably -- called them up and fibbed I have a DFSMS defect -- this perfectly good dataset and my perfectly good QSAM program won't read it. There is no need to trick anyone. If the system issues a message that does not tie together cause and effect (after reading the message description in the book), then you have either a documentation defect or a code defect. The system is [apparently] not operating according to the specification. It is not a how-to for them to challenge your assertion. They must, however, prove it. Really. Consider what happens to a newbie who (a) doesn't know about this list, and (b) doesn't know the internals of DFP, (c) has no prior knowledge or interest in I/O commands responses, (d) manages to mistype the BLKSIZE, or (e) uses an empty dataset w/o specifying BLKSIZE. With any luck, they would eventually have come around to telling me that DFSMS was either WAD, or almost WAD, and my dataset was missing a BLKSIZE. They might have issued a PTF, which would not solve my problem -- my program would just fail with an S013 rather than a Command Reject. I would still have had to change my code to solve the problem (and I'm not for a second objecting to that). I am not suggesting that your coding problem would go away. You did not know what to fix without help. The Messages Codes are supposed to provide the hints. This listserve required a note from me that took 5 or 10 minutes to compose, and 53 minutes later I had the essential clues from Bill Fairchild (thank you, Bill!). I doubt that the Support Center would have done as well. It is, after all, set up to serve a different need. Nothing, I have found, beats IBM-MAIN, LINUX-390, and IBMVM for responsiveness. They're heaven-sent... (I use IBMVM to get customer feedback on development ideas, too. Information flows in a lot of directions. Can you criticize me, OTOH, on the basis that things will never get better if people don't report problems? Guilty as charged. Frankly, the hours in my day are limited, and the time I have available for good deeds I allocate to causes that are more worthy of charity (IMHO) than IBM. IBM has dozens of employees who read this listserve. If it is not worth it in IBM's management's view to seek out problems here and put in the effort necessary to solve them correctly, then why should it be worth it to me? Why should IBM go out of its way to spend money to look for more problems to add to its queue? I don't think that would be a cost-effective business model. IBMers hang out in these places voluntarily and have day jobs, like you. Sadly, those who answer the phones Support Center are not sitting there with time on their hands. Their priority is to work on PMRs. The developers have their priority of implementing the new specifications coming down the road. Every now and then you are lucky and someone who is in the middle of changing some part of the system knows about your problem and fixes it while they've got the covers open and are tinkering with the engine. In this particular case, the knowledge learned here in the past couple of weeks will pass into oblivion. (I'll remember, but who'll ask a VM guy about an MVS error? Nobody.) If having BLKSIZE=0 discussed in the explanation of the Unit Check message would have helped you to diagnose the error, at least send in a Readers Comment Form. And if you haven't done that in a while, it's just an e-mail to mhvrcfs at us dot ibm dot com. The best thing about this listserver is that it gives you choice and more freedom. I would hate to see the discipline mainframers have in the area of problem management be lost to future generations just because we have that freedom. Compare z/OS end user documentation to that of your fave desktop operating system. There is a reason for the disparity and I firmly believe that it is the direct result of the interactions between Customers and the Support Centers. Keep the faith. Semper Fi.
