Re: Can zLinux detect when files arrive in the virtual reader?

I remember the need to use SPOOL RDR CONTINUE when sending files to a second level z/OS or z/VSE many years ago, to avoid START on every file.

I won’t pretend to be an expert in UDEV architecture, but the research I’ve done showed me that UDEV was meant to reflect physical device events to user space. Having refreshed my memory by re-reading “IBM 2821 Control Unit Component Description”, I think the arrival of a card deck in a card reader is equivalent to a USB stick appearing in a USB port. When you press the START key on a 2540 card reader, the device transitions from NOT-READY to READY, causing an unsolicited interrupt (Alert+Device End) that tells the OS to start reading. Once EOF is reached (no more cards in the hopper and the EOF button was pressed), the 2540 signals a Unit Exception, failing the outstanding READ operation that’s waiting for next card. From that the OS knows that the file is complete. Once, the UE is sent, the 2540 returns to the NOT-READY state. In VM, the arrival of a RDR file effectively pushes the START button on the virtual RDR. [I’m not looking to start a retrospective on the 2540 or its modes of operation that differed from the above description. I’m just trying to make a point.] But be careful. While we think we’re interested in the arrival of spool files, we’re not. Rather, we’re interested in knowing that if we start reading from the card reader, there are cards in the hopper to be read. I.e. If a spool file arrives with class Q, but your RDR is spooled class Z, you won’t be able to read the spool file. That’s why seeing the device transition to READY is so important. That only happens if an *eligible* file arrives in you RDR. (Anyone who has written a non-blocking socket application will appreciate that subtle difference.) Cards, tapes, disks. They all had removeable media and they all signaled the host the same way. Even a terminal would generate an unsolicited DE when you turned it on; that’s how the OS knew it was ok to write a logo to it. (I guess the human was the removable media!) This is not to be confused with changes in I/O configuration where subchannels are added to or deleted from the I/O configuration. That’s a whole different kettle of fish.

Hello, Troy. Consider also give authority to individual userids, when justified. And consider products self protection. Example: DIRMAINT have his own mechanism to enable administrators (AUTHUSER), RSCS have self protection for his commands, OPERATOR must be managed by individuals defined into RTABLES, etc., For dangerous machines, use the LOGONBY option, enabling the individuals to logon it, only when need. Example: Network (TCPIP) have the TCPMAINT machine, RACF have AUDITOR, CP/CMS have MAINT. These machines (MAINT, AUDITOR, TCPMAINT) needs LOGONBY. For the few powerful service machines, do not enable them to logon directly (TCPIP, RACFVM, OPERATOR): they must be managed by their partners and must work disconnected.

What do you, the experts, think about? __ Clovis Hi Clovis - I'm not sure I completely follow what you're proposing, but I believe I already covered it (though maybe I wasn't very clear). What you describe seems similar to the design approach I suggested. The challenge is this: There is is only one way to do your first step Know what pages are on the specific DASD; that is to scan all pages in all pageable spaces using CP's translation tables to determine whether each page is on that DASD. Once all pages on the DASD have been located, moving them is easy enough. Finding them is the hard part. The problem is that there is no way to get from the structures representing the 4K records on the DASD (the paging slots containing the pages) back to the structures which tell us what page is in each slot. All we have to represent each paging slot is one bit (allocated or not) in a bitmap, there is no room for a back pointer to the description of the page that the slot contains. So we have to find the pages the other way - from the top down, scanning all pages in the system to check if they are on the volume in question. This is not a small effort. You might ask why we don't just add that missing back pointer; it seems easy enough. It would indeed be easy enough to code, but the cost in terms of the additional storage usage to hold all of those pointers would be prohibitive - for a maximum sized paging system using ECKD volumes pushed to today's supported limits (about 11TB of paging space), it would mean at least an additional 22GB of non-pageable central storage usage just to hold those back pointers - for a function that is only very rarely used. Using a more real-world example: if you have a 32GB system with a 4:1 overcommit ratio of total virtual to real, with paging configured according to recommendations, those back pointers would take up at least 512MB of non-pageable central storage. It just seems excessively wasteful to spend that much central storage resource representing things that aren't even in storage, especially when it's only needed on a very rare basis. - Bill Bill Holder, Senior Software Engineer IBM z/VM Development, Memory Management, Endicott, NY Phone: 607-429-3640IBM TieLine: 620-3640 -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For more information on Linux on System z, visit http://wiki.linuxvm.org/ -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For more information on Linux on System z, visit http://wiki.linuxvm.org/

Re: Red Hat Enterprise Linux 6 - installing problems
Rick, to compliment: Hercules have a IPL_DVD command. No need to map the source .iso file if installing into Hercules. Using Windows as a server, we can mount the .iso file on a free dasd letter (using the freeware program MagicISO by example) and enabling this letter to any FTP server (FileZilla?)... Using any Linux (including zLinux or PC flavors) we can loop mount the .iso file (mount -o loop dvd-file.iso /mnt/cd1) and exporting it (put /mnt/cd1 into /etc/exports) for use with NFS (the better choice). All these options keep the symlinks and enable installation of zLinux without problems. __ Clovis From: Richard Troth vmcow...@gmail.com To: LINUX-390@vm.marist.edu Date: 10/12/2010 14:47 Subject: Re: Red Hat Enterprise Linux 6 - installing problems Sent by: Linux on 390 Port LINUX-390@vm.marist.edu So ... we're glad you're flying now, and you don't need the following, but I will post anyway for reference. Following on what Clovis suggested, you can get Hercules to treat a DVD as an FBA disk. Depending then on the installer, you may be able to install from local media. It is probably more reliable than any network installation. It is certainly more efficient than a network installation. Take a snap-shot of the DVD as a .iso file, just like Clovis said. (Or use the original image you downloaded, if you burned the DVD locally.) Tell Hercules that is a 9336. Then within Linux, load the dasd_mod_fba driver and point to the device thus defined. Voi-la!

In my naivety I would expect z/VM to be *very* aware of an interrupt for a guest IPL. If there are changes in the (z/VM) environment why wouldn't they resolved immediately at that point ?. It's all smoke and mirrors after all. Principle of least astonishment should prevail IMHO. During the development of the CIM models for (all) virtualization, it was recognized that a virtual machine has four states: o Defined - the virtual server is defined within the hypervisor, but is not consuming resources (an entry in USER DIRECT) o Active - the virtual server is running (logged on) o Paused - resources allocated, but virtual server is not running (press PA1 with SET RUN OFF) o Suspended - hibernated (saved state) with no real resources (other than disk) allocated. On System z, applies only to newer Linuxen. There are configuration settings associated with the definition of the virtual server, and there are settings associated with the running virtual server. The runtime settings can be constrained by the definition. Consider memory: it has a default and a maximum value in USER DIRECT. The current runtime value can be anything up to the maximum. It would be a Bad Thing if changing the directory changed a running virtual server. That would seriously hamper proper Change Management and would create havoc in a virtual machine. Some conditions are detected only at virtual server IPL and the virtual server has the expectation that they will remain that way forever, as there is no signalling mechanism to tell it that there has been a change. (Consider privilege class.) This is one of the reasons that revoking a virtual machine's access to a minidisk does not DETACH the minidisk from the virtual machine.

Re: How to enter control characters from an EBCDIC keyboard?
Hi, Sometimes, I forgot to type the cont parameter using the ping command on a 3215 terminal (example: ping -c 4 ip.address). In 3215 terminals, ping without a count result in a forever command. The unique way to stop it (al least the unique I know, without terminate the session) is a Ctrl-C. In this case, I open a Notepad session, click a Ctrl-C pair (^C), paste and copy it in the 3215 session, so stoping the ping command. Obviously, I use it on a PC and using a 3270 emulator that supports copy/paste. I think a Notepad session and copy/past can be useful. Regards, Clovis.

Sent by: Linux on 390 Port LINUX-390@vm.marist.edu David Boyes wrote: I'm working on EBCDIC support for Perl 5. I'm not familiar with EBCDIC terminals, but apparently there are asynchronous ones. Very, VERY rare -- to the point of almost non-existent. The 3270 is the primary terminal type, and it's half-duplex, page-oriented. The older line-mode terminal (the 3215) is emulated, and pretty much behaves as a dumb TTY. How can one enter a control character from such a terminal? On ASCII terminals, pressing the Ctrl key and another at the same time generates a control sequence. Since H is the eighth letter of the alphabet, CTRL-H sends 8, which is a backspace on ASCII platforms. Is there something similar that happens on EBCDIC? The convention to enter a control character is to use the digraph '^letter' (EBCDIC not or cent sign (depending on code page) + character) and have apps translate that to the appropriate code point. The issue is that control characters in a 3270 world don't work the way they do on byte-oriented terminals, so they're rare (if not almost non-existent) in the 3270 environment. In the rare event a control character is used, it's almost always represented as a hex value in a string (for example to enable color or highlighting), and those don't occur as control characters. I don't understand the above. On ASCII terminals, often a control is printed as '^letter.', but entering requires pressing two keys at the same time. It seems like you are saying that the terminal will send a control character whenever a not or cent or maybe caret is typed whenever followed by a letter. If so, how then does one enter these three characters literally? And where could I find a mapping to look at, a sample for one of the code pages? The few EBCDIC code pages that I'm familiar with have 65 controls: 0 to 0x1F plus 0xFF. Are all 65 enterable from the keyboard? See above. I see from the archives that there are some problems between the ASCII LF (or NL) and the EBCDIC NEL. Is there a rule of thumb for which of these, or both, should mean a new-line, matching, say, '\n' in the C language? On a page-oriented terminal, the concept is somewhat difficult to represent. Writing a newline doesn't actually update the screen until you rewrite the page. On the older terminals (3215), the equivalent would be processing a CR/LF pair. In fact, you pretty much need to assume that all line-oriented I/O has exactly the function of a TTY. No cursor positioning, nothing smarter than a TTY. Also, in looking at the Perl 5 source code, it is clear to me that no one is running modern Perl versions on EBCDIC platforms, because it wouldn't work. But I can't imagine a Linux system without Perl. Could someone explain? Linux on z is an ASCII system. Perl works just like it does elsewhere. Ditto with OpenSolaris for Z. There isn't anything in the Z hardware that dictates the use of particular character sets; it's just what you program it to recognize as character graph 'A'. IBM has included machine instructions to help process EBCDIC data, but that's for the convenience of OSes who choose to code data that way. I guess I would ask what kind of EBCDIC support are you creating? Other than providing a string translation function (to_ascii, or to_ebcdic), I'm not sure what EBCDIC support for Perl would mean. Perl already has a codepage mapping toolset, and there are a number of EBCDIC variations, so the question of which EBCDIC? comes up. Are you porting Perl to a specific IBM OS? If so, that might be a very different set of questions. -- db -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For LINUX-390

Re: Has anyone looked into a console server
Good remember, Scott. For who are new to VM, there are some utilities very useful. One of them are SFPURGER (see the manual CMS Commands and Utilities Reference). This does the spool management, purging or keeping files on spool based on age, class, queue, origin, etc. Is one of the functions I run daily using my scheduling routine (WAKEUP running into VMLOGS).

Re: LPAR to LPAR communication
I had some problems with this some years ago. So, I learn something... CNC-CTC (SCTC) are for ESCON channels. The 3088 (or BCTC) are for parallel channels, a pair at each side. FICON channels can be defined both as FCTC, and can be one at each side, not necessary a pair. And with a Ficon Director, we can share a unique FICON channel, defining two or more LCUs, one for each LPAR. There are a document about this somewhere into the IBM world.

Re: Z/Linux CKD DASD migration from one DASD Subsystem to another

Repeat for all minidisks on that userid. Write the CP directory either by hand or using your directory manager. If you want, you can just comment the old disks out in the directory entry in case you need to switch back for some reason. 8) IPL the guest as normal. That id is now running on the new disks. 9) Deallocate the Fxxx disks. If you commented them out in step 8, they are now free disk space until you overwrite them or reallocate the space. 10) Repeat for all guests. If you used dedicated volumes, now you pay for it.

Re: Z/Linux CKD DASD migration from one DASD Subsystem to another
To avoid this risk doesn't put all these disks on SYSTEM CONFIG. If you need repeated volsers, is secure to use fullpack dasd defined as MDISK ... DEVNO. VM mounts them only when necessary and volser doesn't matter I know a VM system that process many Disaster Recovery tests simultaneously, where many customers keep your dasds as 530RES by example. Use of DEVNO keep all secure and independent. Of course, the owned dasds have another different volsers and was mounted at lowest addresses. MVS doesn't work this way, so these dasds must be defined as OFFLINE to other MVS LPARs.

Re: z/VM issues after replicating DASD to DR site
Dresmond, you can solve all this questions only with changes into SYSTEM CONFIG. 1) SYSTEM CONFIG has System_Identifer_Default ZVMCS1, we want our DR to be ZVMCS3 Include Serial Number of each CPU to differentiate. Example: SYSTEM_IDENTIFIER_DEFAULT UNDEFND SYSTEM_IDENTIFIER* %%1341 ZVMCS1 SYSTEM_IDENTIFIER* %%0D06 ZVMCS3 2) I see duplicate MAC addresses on OSA,,, I found the VMLAN MACPREFIX statement, but since it goes in SYSTEM CONFIG, that brings me back to the first issue again. After step 1, prefix each VMLAN card with the Sysid. Example: ZVMCS1: VMLAN MACPREFIX 021341 ZVMCS3: VMLAN MACPREFIX 020D06 3) TCPIP profile needs a different IP address, maskl and Gateway at our DR site. After step 1, TCPIP will use first the sysid profile by default. So, create two profiles TCPIP with different names: ZVMCS1 TCPIP, ZVMCS3 TCPIP, When these files exist, PROFILE.TCPIP will not be used by default. 4) If we make any of the changes above on the DR system, they will get over-written because the DASD replicates constantly. Make the changes on your base dasd before the replication. The two VM images can use the same SYSTEM CONFIG. There are other changes possible in this same line.

Re: z/VM CP commands (LOGON)?
Tom, suggestions: 1- To automate the IPL, I start my Linuxes together with VM, coding CP XAUTOLOG guest into AUTOLOG1's profile.exec 2- To automate Shutdown, there are changes on VM (SYSTEM CONFIG) and in Linux (zipl.conf) Resuming: On SYSTEM CONFIG (can be activated by commands, too): (These numbers are times in seconds and must be adjusted for your installation). See manuals. /**/ /*CP SIGNAL */ /**/ SET SIGNAL SHUTDOWN 30 SET SHUTDOWNTIME 60 On zipl.conf, include the parameters vmpoff and vmphalt: [ipl] ... parameters = root=/dev/system/sistema vmphalt=logoff vmpoff=logoff TERM=dumb These customization will instruct the VM to delay the FORCE until the Linux complete his halt process. Also works for the LPAR DEACTIVATE. And instruct the Linux to do the LOGOFF command itself. See details on VM manuals and in the Cookbooks for RHEL and for SLES. Good luck.

If I have a z/linux guest called ztrash01, I can logon to z/VM as ztrash01, IPL xxx, logon to Linux and shutdown -h now, and if I'm still logged on as console from my 3270 terminal session, enter logoff. No problem. The why I want to do the following is to potentially stress test some applications by forcing off a z/Linux guest (crash) and then eventually trying to automate and re-IPL, but first I gotta be able to do some basic z/VM CP commands below. I read the LOGON in the CP commands and Utilities reference, but I'm doing something wrong (other than trying to trash and stress test my guest). I'm still playing with test systems, but from a z/VM CP perspective, for now the Linux guest ztrash01 is shutdown and halted, but ztrash01 is still logged onto z/VM. 1. If I'm logged on as operator to z/VM, I can issue CP command q n and see that guest ztrash01 is logged onto z/VM and DSC (disconnected). 2. Still as operator, I can issued CP command force ztrash01 logoff immed and this logs the guest, ztrash01, off of z/VM (FORCED BY OPERATOR) 3. Still as operator, a q n verifies that the guest is gone (i.e. logged off z/VM) 4. Now, as operator, instead of going to another z/VM terminal session and logging on as ztrash01, still as operator, I would like to cause the guest ztrash01 to logon (and eventually IPL). To cause the IPL of guest ztrash01 at LOGON, I believe I can put that in the PROFILE EXEC (e.g. IPL xxx) at the end, but how (if at all) can I cause the guest to be logged on (opposite of FORCE) while being logged on to z/VM as operator?

Re: swap to DCSS documentation/cookbook?
Mike, I'm not sure if it is the same case, but Omegamon XE uses DCSS and have some details to take into consideration. The command for define the dcss is: DEFSEG dcssname hexpage1 - hexpage2 type where: - hexpage1 - hexpage2 = the range of pages that are to be saved. Here you specify the starting page and the ending page. - type = the type of virtual machine access permitted to pages in the range. Considerations: 1- if the begin of dcss is lower than the size of the virtual machine, you must open a hole in machine's memory to imbed it. Like it: For a machine with 256M (140 + 116), use this command in Profile.EXEC: DEF STORE CONFIG 0.140M 160M.116M 2- if the dcss is greater, you must inform the kernel where is the end of the memory. If your guest storage is sufficiently low, your entire DCSS address range might be above the guest storage. You can then modify the /etc/zipl.conf file to make the DCSS accessible to the Linux guest. Perform these steps to extend the Linux address range: 1. Add the following command to the [ipl] section of the parameters line in the /etc/zipl.conf file: mem=address where address is an address at or above the upper limit of the DCSS.

Re: Question re communicating with VM guest machine
Andy, many years ago I have a similar problem. The better solution today is work with the products designed for data transmissions, like RSCS or TCPIP, using one of the protocols available (CTC, IUCV, OSA, VSWITCH, VMLAN...). But READER/PUNCH also works to send files to a second level VM. Don't forget that the Reader for the second level VM looks like a physical Reader. So, the data received must contain a header like the real world to identify the destiny. Try sending the files using a EXEC like this: /*/ arg fn ft fm vm2lvl . ( user2lvl If fn = Then Do Say Missing Filename to send. Exit End If ft = Then ft = * If fm = Then fm = A If vm2lvl = Then vm2lvl = ZVM530 /* -- adjust */ If user2lvl = Then user2lvl = MAINT/* -- adjust */ CP SPOOL PUN TO vm2lvl CONT header = left(ID,8)||left(user2lvl,8)||NAME vm2lvl userid() EXECIO 1 PUNCH (STRING header LISTFILE fn ft fm ( EXEC ARGS CMS DISK DUMP ERASE CMS EXEC A CP SPOOL PUN NOCONT CP CLOSE PUNCH CP SPOOL PUN OFF Exit This exec sends multiple files on a single transmission, and DISK DUMP can manipulate records greater than 80 characters.

Re: V-Disk sizing question
To define, you can use DIRMAINT. See this partial help from command DIRM AMDisk: V-DISK provides virtual disk space to a user upon logging on. The V-DISK may already exist when the user links to it, providing other users that previously linked to it are still linked when the user logs on. Otherwise, the owner must initialize or format this minidisk at each logon. It remains a part of the owner's virtual configuration until logoff or disk detachment. When the last linked user logs off or detaches the V-DISK, the file space is returned for reallocation to another user. VDBS is functionally equivalent to V-DISK except that the size is specified in units of CMS 512, 1024, 2048, or 4096 blocks rather than in CKD cylinders or FBA blocks. Valid values are: VDBS512, VDBS0512, VDBS1024, VDBS2048, VDBS4096, VDBS1K, VDBS2K, and VDBS4K.

See this partial help from command DIRM AMDisk: V-DISK provides virtual disk space to a user upon logging on. The V-DISK may already exist when the user links to it, providing other users that previously linked to it are still linked when the user logs on. Otherwise, the owner must initialize or format this minidisk at each logon. It remains a part of the owner's virtual configuration until logoff or disk detachment.

You can define the vdisk size to whatever you want. I typically use 32MB for some machines more for others, depending upon the machine. Steve Gentry wrote: Is there a 1 to 1 correspondence in the size of the VM linux machine (user directory entry) and the amount of swap space either mdisk or v-disk? Linux usually doubles the size of the defined memory. So, for example, a Linux guest is defined with 100 meg, the swap size will usually be around 200meg Do I need to define a v-disk size of 200meg? Also, what is the latest and greatest way of setting up a v-disk? I've found different examples. Some are a few years and the technique are applicable to the technology back then. Procedures have progressed etc. I didn't want to spend time on using an old technique when a newer more stream lined method would work. Thanks, Steve G
