Re: ECKD driver vs DIAG driver
LDL format was the first format used by Linux. It was quickly replaced by CDL format. The main difference is that a disk in CDL format is seen as being full by all other operating systems (VM, VSE OS/390). However, they see a LDL fromat disk as being empty. Thus if you are going to run anything other than Linux on your Z196 you must make a special effort to keep the other systems from over writing the Linux disks in LDL format. The other systems will not automatically over write a CDL format disk as they think it is already full of data that can not be deleted. DIAG works with CDL format. As DIAG was added to Linux after CDL format was in wide use, I don't know if support for LDL was added to DIAG. (It probably was.) The only advantage to LDL is you may be able to have 1 additional 4K block of Linux data on the disk. There is no reason why you can't put /boot on a DIAG disk. There are some restrictions to where you can put /boot. -- Stephen Frazier Information Technology Unit Oklahoma Department of Corrections 3400 Martin Luther King Oklahoma City, Ok, 73111-4298 Tel.: (405) 425-2549 Fax: (405) 425-2554 Pager: (405) 690-1828 email: stevef%doc.state.ok.us On 1/3/2011 9:59 AM, Samir Reddahi wrote: Disks are currently formatted with cdl.

Re: How many virtual servers per IFL?
If you are comparing VM and VMware, I would estimate that 1 IFL will support about the same load as 5-10 HP blades running ESX. How many virtual severs will VMware support?

Re: OT (was Re: RHEL 5.4 Beta is out in the wild)
Note the USMC logo. The anchor chain is wrapped around the anchor. So, all marines are always fouled up. ;-) The use of the fouled up anchor as a symbol of the marines goes back to at least the late 1700's. The term SNFU or SNAFU (I have seen it both ways although the later is now the more common) may go back that far also. My father told me that he first encountered the term SNFU as Situation Normal Fouled Up when he joined the Navy in 1932. The other F word would not have been used in 1700 as at that time it was a device pulled by a farm horse to plant seeds. It didn't take on its current meaning until some time in the 1800's. Could it be related to sowing wild oats? How far OT do we want to go with this? :-) bruce.light...@its.ms.gov wrote: one more view - 3 of my great uncles were marines - 1 in 1918, WW1 in France.

As Dave Jones is running Ubuntu it is likely packaged like Debian. If it is - check that you installed the package xfonts-x3270-misc. On Debian package x3270 only recommends it.

The difference is striking. X3270 without its real 3270 look-alike fonts ... well ... it sucks. From the tone of your note, Dave, I think you do NOT have the true X3270 fonts.

The reason for EBCDIC codepoints 15 and 25 is to be compatible with the IBM Selectric Typewriter. One of them would roll the paper forward a line with out moving the type ball. The other would put the type ball at the beginning of the next line. Also their is another codepoint 0A that moved the type ball to the beginning of the current line so you could over type what had been typed. This was an important security measure. After the user typed a password you should do a 0A followed by a string of E7 (X) to make the printed password unreadable.

Re: z/VM 5.1 to 5.3 upgrade ( a little handholding requested) PART 2
So far your approach is good. See some comments below. Peter E. Abresch Jr. - at Pepco wrote: Thanks to everyone that responded to my original hand holding request. With everyone?s response we were able to install z/VM 5.3 as a second level guest to our z/VM V5.1. We also applied the latest RSU maintenance and have performed backups of our 5.3 system. We are now looking to migrate our users (system programmers). Remember, we only use z/VM for Linux guest only. I was going to migrate (cut and paste) our z/VM 5.1 guest directory entries into our z/VM 5.3 user direct and perform a DIRECTXA which should work. We only have about 20. But. . . . we have some sharing concerns. Yes, copy the user entries from the old directory to the new directory. For example: I want to cut the following entry from user direct on z/VM 5.1 and paste it in user direct on z/VM 5.3 and put it online. USER X062PEA 64M 100M ABCDEFG INCLUDE IBMDFLT ACCOUNT 1 SYSPROG IPL CMS MACH XA OPTION MAINTCCW LNKS LNKE LNKNOPAS LINK TCPMAINT 0592 0592 RR MDISK 0191 3390 11 5 VMUSR0 MR MDISK 0199 3390 31 100 VMUSR0 RR Volume VMUSR0 looks like the following under our current 5.1 system: DASD 6815 CP SYSTEM VMUSR0 13 Here are the questions. Can I attach 6815 to my second level z/VM 5.3 guest and then logon with x062pea or do I need to detach it to our first level z/VM 5.1 system. I would use a link to a full pack minidisk to give your second level guest access to the disk. If you use link then both first and second level users can access different minidisks on the disk at the same time. If you use detach and attach then you can not have users on both systems at the same time. Are they any sharing concerns that I need to be aware of? Do not have the same user log on to both first and second level at the same time. Two users should not have write access to a minidisk at one time. In your example minidisk 0199 is read only so it doesn't matter how many users have it. However, minidisk 0191 is set so that it will get a write access to the minidisk if no one else has one when it logs on. But, it will get read only access if someone else (at the same level on this lpar) has write access. If you are an experienced VM systems programmer you would have set up your machine to propagate the protection across lpars and levels. If you are not experienced enough to do this then be careful not to have two write links at the same time. Our final z/VM 5.3 test will be ipling it in a separate LPAR. Are their additional sharing concerns I have to worry about? If you followed my advice to use link instead of attach then there is no change in sharing concerns when you run both VMs in lpars instead of one under the other. If you were using attach when running in one lpar when you bring it up in a second lpar you will have the disk attached to both VM at the same time. That introduces all the concerns that you would have if you used link. Anthing that will get us on the right track is appreciated. We want to make sure that we do not cause problems with our production z/VM, especially over the long holiday. Thanks as always. Peter Remember, we are old MVSers but very young VMers. Go slow.

Re: curiousity question: Linux usage: many or few
Cost savings. On discrete boxes (Intel or LPAR) run multiple applications on one Linux. Adding another box costs money. Adding an application to an existing box costs zero. On virtual systems (z/VM or VMware) run one application per Linux. It doesn't cost anything to define another guest.

It usually happens because once you have a Linux system you can add applications to it without having to buy another server, as opposed the Windows world where adding a second application causes the first one to break. Interesting. I often see the opposite with Linux on z/VM: one application per server. That may have to do with many Linux on z/VM shops running commercial (i.e. paid and supported) application software that have their own specific incompatible software requirements and configuration settings. And if it would work they would not be supported in one virtual machine. Change management and testing is also easier. I could not imagine anyone running TSM, SAP, WebSphere etc all in a single virtual machine if they have the option to split it up. I think it is even rare to run multiple WebSphere application servers in a single virtual machine. From a tuning and charge-back perspective, it is often attractive to run in separate virtual machines. That way you can allocate resources as required. Even though there is a cost involved in extra virtual machines and communication overhead, the advantages normally make up for that.

Re: dasdfmt -d cdl and FDR volume backup
Anyone who has been on VM long enough has seen this. When you CPFMTXA every cylinder of a volume you know that every track has been properly formated. If you DDR or FLASHCOPY or FDR or anything else it formats the tracks that are in use on the source volume. That might not be all of them. When you try to use a cylinder later (maybe years later) for something other than it use at the time it was formated by DDR etc. you may get strange errors because some track is not formated correctly.

Re: vm profile question
If you have 2 real CPUs, they are real CPU 0 and real CPU 1. Real CPU 0 will never be dedicated to a guest. If a guest logs on and has a dedicated virtual CPU and a real CPU is free that is not real CPU 0, A real CPU will be assigned to that virtual CPU. If a real CPU is not available then the virtual CPU will be one of the CPU that can be dispatched on any available CPU. The effect of having the statement CPU 01 DEDICATE in every guest with only 2 real CPUs is - The first guest to logon will have real CPU 01 assigned to the guest as virtual CPU 01. That guest will be the only one using real CPU 1 until it logs off. All other guests that logon while real CPU 1 is assigned will be placed in the dispatching queue. Those guest will be dispatched on real CPU 0 as it is the only one available. So we have the first guest using real CPU 1 and all other guests sharing real CPU 0. If the first guest logs off, that will free real CPU 1 and VM will start dispatching guests on it. Then we will have all the guest sharing both real CPU 0 and real CPU 1. However if another guest logs on it will then be assigned CPU 1 and VM will stop dispatching the other guests on it. Unless you only need 1 real CPU to get your work done, you will see strange performance problems. You will have one guest running well and all the other guests doing poorly. But when the guest that is running well logs off everyone else will start running well until a new guest logs on and then the other guests will go back to poor performance. RPN01 wrote: Someone else had said something about only the first guest logging in being dedicated, but I don't think that is how it would work; If that were true, guest one would get CPU 01, guest 2 would get CPU 00, and everyone else would starve for CPU.

Re: Forwarding guest console to a syslog server
The secondary console facility (SCIF) can be used to send the console messages form any guest to a SVM (service virtual machine). On the SVM you would run PROP (programmable operator) to process the messages. PROP can be set up so that depending on what the message is it will respond to the message, log it, ignore it, or run a REXX program using it. Their are more actions that PROP can do but those are the most common. All of the above has been part of VM for at least 20 years. :) Patrick Spinler wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 A question for all you good folks.

Re: Peoplesoft/Oracle on SUSE Linux under zSeries
We currently have a Peoplesoft system that needs to be updated. Peoplesoft is several versions behind, Oracle is v8, and it is running on a bunch of old Netfinity servers with Windows 2000. We asked several companies to propose a turn key upgrade. They will install new servers, a new operating system, the latest Oracle and the latest Peoplesoft. Then copy our data to the new system. Setup a DR plan. And they must be a single contact point for support. The proposal from IBM uses a z9 server, dasd with remote copy, z/VM, and z/Linux. I think IBM has a good chance of getting the bid. It would appear that the division of IBM that is bidding on the project thinks it will work and be supported. I don't know the details of the IBM solution, as I haven't been at any of the meetings with IBM. I am the VSE systems programmer so they didn't think I would be interested. :( If IBM does get the contract, maybe they will let me run my VSE systems on the z9 also. :) Craig Collins wrote: We are considering running the Oracle databases for a Peoplesoft implementation on SUSE guests running under zVM.

Re: really INSANE question - network IPL?
You need to go to the Debian lists. Some people have placed a Debian S390 install DVD in the HMC and IPL from it. It seems to work for some people. Someone is working on a liveDVD that will work on any machine. The last I heard he had it running on about 4 different kinds of machines (Intel, RS6000, ADM64 and something else).

One thing that a PC can do is boot from a network source, called PXE (http://en.wikipedia.org/wiki/Preboot_Execution_Environment). Now, IBM has made it so that an appropriate OS (i.e. Linux) can IPL from a SAN (SCSI IPL). I was just considering what it might take to IPL from a network server instead. Granted, this would likely only be to IPL Linux. And I guess something like this could be emulated by booting PXE compatable software from a DVD on the HMC.

Re: Cloning RHL in an LPAR - to run on another Hardware?
You do exactly the same thing as in the howto. When you change the IP address and the disk addresses you change them to the correct addresses of your cold site. You then copy the changed system to the cold site. [EMAIL PROTECTED] wrote: Hi Mark, many thanks for taking the time to publish the howto. Basic condition for cloning is that the cloned system should run on the same hardware. But what if one wants to clone the system tun run on another hardware?

Re: routing verification
On the VSE system you are using IP addresses of 192.168.099.nnn on the OSA and IP addresses of 192.168.193.nnn on the hyperchannel. That is probably good. However in your previous message on the LINUX system you were using IP addresses of 192.168.192.nnn on both interfaces. That doesn't match. You probably should change your IP addresses on the LINUX system to be compatible with what you are doing on VSE if that is working.

Create a new userid with 29 packs in the VM directory. 3. Clone an exising sles9 server (ddr existing server to first new pack) 4. Bring up server configure it (different IP address than production, different OSA addr, etc) 5. Activate the 28 new packs with yast. 6. Create lvm with the 28 packs 7. Shut down the new server and DDR the production 28 packs to the new server. 8. Install software needed for the new server. 9. Bring up server and test 10. Shut down production server change ip osa addresses of new server 11. Bring up new server as the new production server. Does anyone have other suggestions or a better way of doing this ?

Re: z/Linux equivalent of VSECMD?
VSECMD is CMS program that passes a command line to a VSE system and returns the output of the command to CMS. It is useful as a CMS command the output comes back to your screen. It is even more useful in a REXX procedure where the output can be analyzed by the procedure. I don't know of any equivalent for Linux. There is a program to do the reverse - Linux can issue a command to be run on VM.

Re: Next dumb question: Searching for a product

Obviously, by name won't do much good. I may have a need to produce a PDF file, which we are currently doing in VSE. However, in this case, we need a forms flash, or forms overlay on the form also. This is a low volume operation, so I'm not worried about resources on our IFL. Right now, we have one of the big Xerox machines to do the bulk printing. However, sometimes the departments needs a reprint of a single form. We would like to send it directly to their printer with the correct overlay.

It would be nice if we could use the same MS Word document for input to this process. But I haven't the foggest idea on how to search for this.

Re: Increase memory of VM Guest
Almost. Between step 4 and step 5 you must add step 4a. logon the guest. You don't have to logoff the guest in step 0. That can be done at any time before the new step 4a.

Re: Hipersockets..... a couple of questions
If you are running VM in 31 bit mode then you should change to have real 2 GB and expanded 1 GB. If you are running VM in 64 bit mode then your current real 2.5 GB and expanded .5 GB is ok. [EMAIL PROTECTED] wrote: Not in 64 bit mode that I* am aware of, except of course that it's on a z/box. Im not involved heavily in the VM side of things, but we're NOT running 64 bit linux if that is any indicator. If you have 3 GB available, presuming that VM is running in 64 bit mode (I would have to think that our very experienced z/os people would realized that anything over 2 GB in 31 bit mode is 'lost') what would people say should be the allocation? We're trying to get as much real storage as possible, and frankly, I don't think we have a real good idea of what to do with expanded storage in vm as it relates to linux. We don't have ANY defined to the 2 GB lpar on the z/800 at the moment because the recommendation from IBM to make some memory expanded stor for VM came after we did our last config. If we're in 31 bit mode on z/VM we should do 2 real and 1 expanded? We change the config on the 23rd of this month, so I want to get it right. The next time we can change the config is july 18th but the POC will be over by then.

One big area that we still see latency is RACF/LDAP authentication across the network. Can hipersockets be used to make RACF/LDAP calls also? We are going to be configuring z/900 to use hipersockets on z/linux and z/os...
