Re: Virtual Lock File
Another way would be to define a VDISK in the PROFILE EXEC of the VDISKS machine (instead of VM directory definition) and check the return code of CP DEFINE (if it's 0, initialise it). I forgot to say that in this case you would have to add 'CP LINK VDISKS 222 vaddr MW' a second or two after 'CP XAUTOLOG VDISKS' in VSE machines' PROFILE EXECs. Also, you may choose to add COMMAND XAUTOLOG VDISKS directory control statement for all VSE machines, which would work even if you IPL VSE straight from directory by using IPL sysres_addr directory control statement, and then you don't even have to worry about VSE machines' privilege class to be able to run XAUTOLOG CP command.

SMTP authentication?
Hi, This morning we have a new problem in the z/VM SMTP server. Email to the local network is failing, with this message appearing in the SMTP console: 3 530 5.7.1 Client was not authenticated Could someone please explain: a) what this actually means (it didn't use to happen)? b) how do I solve it? All of our email is sent to the network SMTP server IPMAILERADDRESS ALL network SMTP server name We are on z/VM 5.4.0, 0903. Thank you very much, Shimon

If MVS doesn't know that the DASD is shared with another system, it won't attempt to put a RESERVE on the volume. Virtual reserve/release is a facility in z/VM that virtualizes RESERVE and RELEASE commands issued to a device by guest operating systems. The RESERVE and RELEASE commands are translated to no-ops by CP; so they never get sent to the actual DASD controller. But CP keeps track of them and won't allow guest number 2 to access the volume if guest number 1 has put a RESERVE on it. But if the guest operating system doesn't issue a RESERVE in the first place, this facility does no good. You need to make sure that the DASD is defined to the guest system as SHARED. I'm not a z/OS expert, but I think that stuff is in HCD/HCM. Of course, when running as a z/VM guest, you don't need to worry about the IOCDS stuff. CP virtualizes that. But the IODF part you do need to worry about. What happens if two developers open the same z/OS library dataset member on this A80 unit? Will the second one entering be denied in SPF? If not what happens if they both store their changes? Well, that depends. There are several layers to this. The first layer has been discussed above. You need to have full pack minidisks defined with virtual RESERVE/RELEASE, both systems have to link to the same minidisk R/W, and both systems must define the DASD as SHARED. Then there are GRS considerations. (GRS stands for Global Resource Serialization. There are MVS manuals for that. It can do stuff like convert ENQs into RESERVES or vice versa. I'm no GRS expert, but I think GRS can be implemented without a SYSPLEX.) I'd start with the GRS manuals. In general, locking is at the dataset level. So two different jobs (or TSO users), even if they are on the same system, cannot normally share the same dataset at the same time unless they both allocate the dataset with DISP=SHR. However, the ISPF editor may be a special case here. I believe there are additional locking mechanisms within the ISPF editor that may safely allow separate members in the same dataset to be processed by different users at the same time. But that is an MVS question and does not belong on this forum. -- .''`. Stephen Powell : :' : `. `'` `-
Re: Sharing files between two z/OS guest machines
I don't run z/OS guests under our z/VM systems so I can't answer what you might need to do in z/VM. On the z/OS side you need to consider how far do you want to go with sharing. Do you want to have the same file open on both systems? Or are you just trying to find an easier way to move information between systems? To share a file between systems you would need to have something like GRS or CA-MIM set up on each system and CTC connections between systems. You need to sit down and think through how much sharing you want to do and how much time and effort you want to put into setting things up.

Re: Sharing files between two z/OS guest machines
Actually, the latest version of zPDT does support zVM's Virtual Coupling. It does not require any underlying hardware support and it works reasonably well (I've run some tests on our systems). The Sysplex environment is a bit complex, especially from an operational point of view and is not for the faint of heart, but it works. When I set up uPDT systems for our customers I have a 'owner' VM with full pack definitions for the disks to be shared (normally only a subset of all disks) with MWV and each 'using' VM has a MW link to these full-pack minidisks. Yes, the default zOS HCD/IOCDS defines the disks as shared.

RSU, PSP - which do I choose?
I have installed our z/VM 5.4 system (YAY!). It came with RSU 5404 from June 2009, so that’s what I installed. It has not yet been migrated. Now I read the part in the z/VM Program Directory that says, “…you sh ould see if you received the most current Stacked RSU available. If there is a higher RSU available, or if you did not receive an RSU with your order an d there is now one available, you should order it and apply it when you install z/VM.” Well, since this is my first solo z/VM installation, I’m not quite sure what I should do at this point to bring it completely up-to-date prior to the migration steps. Should I: 1. Order the latest stacked RSU (and then what… start over with the installation?) 2. Order the PSP “buckets” for the three products we use whose SERVLV L is higher, and apply just that service? Suggestions? Be gentle... the expert at anything was once a beginner. :) Thanks. Sherry E.
Re: RSU, PSP - which do I choose?
Hi, Sherry. Congratulations on getting z/VM 5.4 installed! What you should do next is order the latest z/VM 5.4 RSU (it's 5408RSU dated October 29, 2010) from the z/VM web site and install that on top of 5.4. How to do that is described in Chapter 14 of the z/VM: Guide for Automated Installation and Service publication. Have a good one.

Re: Sharing files between two z/OS guest machines
Actually, the latest version of zPDT does support zVM's Virtual Coupling. It does not require any underlying hardware support and it works reasonably well (I've run some tests on our systems). Well that's pretty cool! Marcy
Re: Sharing files between two z/OS guest machines
We have run MVS guests under VM, and in LPAR. The answer was the same for both, and has already been suggested. Given that the dasd is linked to every z/OS guest correctly (and having a dasd owner user with all z/OS guests with r/w links to the dasd is what we used), it is up to the z/OS system to keep track of who has what file. For longer than I have been here, the MVS systems have used CA's MIM to manage the sharing. To the z/OS guest, its like shared dasd in LPARs. We pick up z/OS LPAR's today and go to a DR provider where they run as guests under VM. MIM does the magic that protects the shared data, no difference.

Re: SMTP authentication?
Thank you very much for the explanation. The part about There is nothing you can do to fix it. takes the onus off of me, but I still need to get the network kiddies to fix what they broke. I was wondering - is it really necessary for them to allow ALL anonymous mail, or can it be selectively by IP address? Whoever had a bad dream about SMTP security, and decided to close the awful breach of anonymous email would certainly prefer to allow only the IP of the z/VM system. With the situation as it is today, that most SMTP servers do seem to require user/pwd authentication, it seems unfortunate that ours cannot authenticate to the network server. Or is that something servers never do between themselves, just email clients? BTW, we have no REAL gateway, all email is internal only. Thank you very much!

It should work fine on a z890 (it was built on a 7060-H70 and tested on a z800, so it should be OK). Give me a few days to package it up and put it somewhere for you. It can also serve as a complete replacement for the VM SMTP (thanks to M. Beattie's UR driver), but I'd recommend just using it as a proxy for now.

Order the PSP “buckets” for the three products we use whose SERVLVL is higher, and apply just that service? Suggestions? Be gentle... the expert at anything was once a beginner. :) Thanks. Sherry E.
Re: RSU, PSP - which do I choose?
Order PTF UV97540 and you will got lastest RSU for z/VM 5.4. (1008) This is good advice and gets you most of the way. Since RSUs are collections of recommended service made at a specific point in time, make sure you also order the PSP bucket for that RSU to catch anything after the RSU date that wasn't included on the RSU. Background: What you're doing is three things: installing the base code, using the RSU to jump forward in time and apply all the service from the base up to the RSU date in one operation, and then layer any fixes that have been made after the RSU was closed. You've gotten the base code installed, and (if you want) you can use the RSU that you have to practice installing the RSU (when you get the new stacked RSU and PSP tapes, the SERVICE tool will figure out what you have already applied and just add the new stuff. Mother's Rules of Thumb: 1) Never mix IBM stuff and your stuff. 2) Always take a backup of your entire MAINT id BEFORE you THINK about applying service 3) Cupcakes get you faster responses to your service problems. 8-) I'd strongly encourage you to just do a SERVICE ALL with the RSU and let the automated stuff process the service. If you aren't using CMS for anything except maintaining the system, it does a pretty good job, and anything it can't handle, you're going to need to call IBM for help anyway. The VM service tools are heap big magic even for us oldtimers.

Re: cpuplugd Daemon
Let us know if you find a productive use for it. Crashing a guest is the typical result. Better to spend you time SIZING the guest.

I don't think even IBM recommends VMRM (ok maybe some sales types do). The problem is about your ability to keep your servers from not crashing if you care.. Dave Jones wrote: Hi, Rakesh. A good place to start learning about the z/.VM side of CMM is the z/VM V6R1 Performance document, available from the IBM z/VM online library. The VM side of CMM is implemented by the VMRMSVM virtual machine, which is already defined in the user directory. Chapter 4.6 in the Performance document above describes how this works in detail.

We have found a reference in Virtualization cook book for SLES11 SP1 how to make necessary configuration for CMM modules within Linux.But couldn't find any reference about the configuration to be done within z/VM for CMM. Is any configuration required or z/VM comes with CMM enabled by default. The z/VM version used is 6.1 and Linux is SLES11 SP1. Also does this process have any adverse performance implication?

Do QUERY FILEPOOL CATALOG to see the amount of catalog data blocks and catalog index blocks used. Total number of catalog space blocks (data+index) is MAXUSERS*85. Maybe your MAXUSERS value is too small? Ivica Brodaric BNZ
