RACF and access to minidisk
Dear all, Just a question regarding z/VM RACF protection of access to a minidisk. A LINUX guest tries to access another minidisk which is protected by a RACF profile. It is not authorized to link the minidisk and the link request fails. When I authorize that guest on the RACF profile the link still fails until I LOGOFF/LOGON the LINUX guest. It seems that the permission list of the profile remains in the storage. Maybe a stupid question but how can I refrsh the access authority without recycling the LINUX guest? Thank you very much in advance, Kind regards, Florian
Re: RACF and access to minidisk
Dear all, Thanks for the feedback. 1.) The VMMDISK class is NOT RACLISTED. 2.) The profile looks as stated below. 3.) I added LINADM to the permission list. 4.) Before LINADM was recycled, RACF told: ICH408I USER(LINADM ) GROUP(SYS1) NAME(## CLONSET4.201 CL(VMMDISK ) INSUFFICIENT ACCESS AUTHORITY FROM CLONSET4.* (G) ACCESS INTENT(ALTER ) ACCESS ALLOWED(READ ) 5.)

Question to CMS plumbers (PIPE)
Dear all, Maybe it is the wrong forum but I do have a z/OS related question: In the documentation of the CMS pipelines there is alwas a reference that it supports TSO z/OS as well. However I am not able to find a clear indication if this is still the case or it is mentioned only for historical reasons. I would like to ask if there exists a HOWTO to get pipleines working under TSO/REXX. z/OS 1.11 Does anybody has more concrete information about this? Thank you very much in advance. -- Best regards Florian
Re: Question to CMS plumbers (PIPE)
Thanks for the feedback. I will forward the question to my IBM representative. Let's see what that Delivery offering means. I read about this in the Author's Guide. I think even the Batch pipes are not going to be further improved, There should be some sort of unsupport ed way as it is done in CMS where you can replace the official version by th e current ones of MARIST.

Re: Second screen in a z/VM CMS session
Dear Peter, I looked already into Yvette some time ago but it does the other way roun d. It is a session manager. With Yvette you can logon to DIFFERENT VM guests from ONE screen. I would like to have multiple screens to ONE VM guest. A more appropriate tool is CONINT also from the IBM utility download site . It allows to switch between several tasks in CMS. Here the xedit session would be one task and the testing of the REXX exec is another task. It is possible to switch between those tasks but a second screen is also not supported. However CONINT doesn't run under z/VM 5.4. respectively the actual CMS versions. Seems that the proposal of Kris is the only real practical solution. Thank you for that.

Re: ODP: Second screen in a z/VM CMS session
Thank you for this clarification about multitasking in CMS. Maybe I was not precise enough. I would like to avoid always invoking XEDIT in order to change some line of code in the REXX exec during debugging. The idea was to have the file ope ned in XEDIT, save it and then run it on a second screen connected to the sam e VM guest. But this was only one example. I was looking for a more general solution, where there would be two programs loaded in storage at the same time. Seems that this is not possible. So it is better to have a second VM User accessing a SFS. Thank you for the feedback.

CMS Multitasking is very limited. It is really multithreading. All CMS commands must run in the base thread, so you cannot run two commands such as XEDIT and the EXEC a t the same time in different threads -- even if you do have a second console. True multitasking in VM is accomplished by using multiple virtual machines. You can switch back and forth between running and editing an EXEC on a single console. But the EXEC has to be saved and restarted each time. (I do that all the time.) Using Shared File System, you can run the EXEC in one virtual machine and edit it in another one. You still have to save and run the EXEC from the start each time.

Re: Question on PIPEprogram THREEWAY
Hi Mike, Thank you for this information. As you say, I am concerned to modify and/ or use features from pipes that are not in the original delivery. We had already bad experiences using features not clearly supported by IBM in operational environments. So we are quite reluctant to use other than the original components. For the possibility of running both versions, I need to study a little bi t more how this is working and will implement it then. On my system the pipe query version command gives back: CMS/TSO Pipelines, 5741-A05/5655-A17 1.0110. I think the manual from the z/VM library should refer to exactly that version. So, the THREEWAY function is probably not part of is. I have ope ned a PMR for that. Let's see what will come back from the support team. It is really a pity that IBM does not extend the functions of PIPE. It is totally unclear for me that this is happening and I would support a chang e in the policy. But I think this is not the only component that is frozen in z/VM, isn't it? What is going to happen with z/CMS? This is also in z/VM V6.1 not really supported. Kind regards, Florian

Question on z/VM LAN (VSWITCH) Routing
Dear all, I have the following situation on my z/VM system: There is a switch VMSWI1 to this switch all the LINUX systems and the z/VM stack is connected. The network is 151.100.1.0/24 VSWITCH SYSTEM VMSWI1 Type: VSWITCH Connected: 17 Maxconn: INFINITE PERSISTENT RESTRICTEDNONROUTER Accounting: OFF VLAN Unaware MAC address: 02-F1-00-00-00-04 State: Ready IPTimeout: 5 QueueStorage: 8 Isolation Status: OFF Portname: TCPIP RDEV: E100.P00 Controller: DTCVSW2 VDEV: E100 Ready; T=0.01/0.01 10:35:13 I would like to set up now another LINUX Instance that will act as a firewall. It should have the IP address 151.100.1.100. So it needs routing to another network (151.100.16.0/24) To my understanding I have to change VMSWI1 to a PRIROUTER. Nevertheless, I would like to change the switch also from layer 3 to layer 2. Therefore I wanted to define another switch (VMSWI2) on another real OSA adapter VDEV E200 and connect the LINUX firewall to this switch and later to migrate step by step the LINUX systems onto this switch. The RDEV E100 and E200 are connected to the same real switch on the network. However it seems this is not working as E200 does not receive any traffic bound to 151.100.1.100. We are sure that the configuration of the real switch in front of z/VM is correct. I wonder if my proposed configuration would be possible since I read in z/VM Connectivity book that the same LAN segment must be either layer 2 or layer 3. I would need to have a more precise statement: Does the layer2/3 effect only one switch on a real OSA or the whole z/VM instance? Thank you very much in advance. Kind regards, Florian
PPRC commands under z/VM
Dear all, I need to establish several PPRC pairs between two DS-8000 at our local site for our z/VM system. There is a lot of information around about this matter but unfortunately it is still not totally clear to me, if there are native z/VM commands for manageing the PPRC pairs or do I need to use ICKDSF to achieve this. Referring to the DUPLEX command I find it ambigous what is stated there as it referes to 3990-3 and 3990-6 controllers only. Would be nice to have some reference regarding PPRC, clarifying that this is not for DS-8000 PPRC. I would like to prepare scripts that establish or break the pairing if necessary.

Reaction of z/VM when losing a page dataset
Dear all, I am wondering about the reaction of z/VM in case it would lose one or two page datasets. The reason is that I have a configuration with two DS-8000 where the page datasets are spread all over those two machines. DS-1 has the sysres, spool, and some page datasets and DS-2 it has additional page datasets. The system disks are mirrored by PPRC. So in case DS-1 will become unavailable I can continue on DS-2. This will be disruptive of course. Since the page datasets consume a lot of addresses we don’t mirror them. In case DS-2 would become unavailable, would z/VM then crash? Would it be better to have all CPOwned volumes on one DS-8000 or can my current configuration remain as it is? Any opinion is appreciated very much. Furthermore I would like to ask if the new version of z/VM will allow emptying a page dataset in order to drain it and detach it without IPL. I just experienced that a drain of that volume not really helps. Thank you very much in advance. Kind regards, Fox

Using VTOD
Dear all, Due to historical reasons we run our host systems on local time (CET/CETS = EAST +1h/+2h). Well, all the years this served well but due to some services that require UTC we have to change now to UTC. In a first stage we would like to run only those services necessary with UTC. In order to carefully test our applications we are using z/VM and the VTOD feature were we can simulate the test systems (z/OS and z/LINUX) the switch of the hardware clock to UTC. This works but for the operating staff it is quite a nightmare. What I mean is that we have to define a Reference time that is exactly 1 hour from the system time. There we face following issues: 1.) The SET VTOD command does not accept parameters such as current time -1h. This is quite problematic since we will always have a small difference from the hardware clock depending how exactly the operator entering the time and hits enter. 2.) To use this time for the MSGPROCs and GUESTmachines we defined a User called GMTETR that is nothing doing except setting the time and run as time source. Unfortunately, since the SET VTOD makes a system reset, this user drops after the command to CP READ and after some time it seems to be logged off from the system. This is quite annoying. We tried CONCEAL option in order to REIPL the GMTETR machine but nothing is happening. I would like to ask two questions: How can we set a time difference of exactly one/two hours from the hardware clock? What can be done that the GMTETR is not forced from the system? Thank you in advance, Kind regards, Florian

Sharing the RACF database in CSE
Dear all, I am planning to setup RACF in a CSE environemnt. The CSE is on two different processors. I have read in the Program Directory that in this c ase the RACF database mustn't be on a CSE formatted volume since it uses real reserve/release CCWs. Therefore I can put it only on a real volume and dedicate it to RACFVM or make a fullpack minidisk out of it. Isn't that an overkill of dedicating two full 3390 addresses (5 GB) for 2 x 17 cylinder of data, the size of the database?? Could I put the Primary and the Backup at least on the same volume?

I have now the necessary CTCs and wanted to activate the IS-links. Howeve r I saw with q resources that a name called .RECOVER coming from VMSERVR is global. Resource: .RECOVER Type: Global Owning Userid: VMSERVR What should I do now? I am a little bit lost. Can you please advise me in this subject?

Hi Kris, Thank you very much. This helped me a lot.

Beware too if CRR would have in its log transactions that must still be commited/rolled back. You should not activate the IS-link before the resources are made unique, otherwise some things may stop working. But, as far as I know, SFS and DB2/VM are the only users of CRR, so only their users could get in trouble. 2008/8/27 Florian Bilek [EMAIL PROTECTED] Dear all, Last month I was asking to establish a ISCF connection between two z/V M systems.

I didn't find any additional information for eventual additional configuration of REXECD on this in the documentation, so maybe somebod y has experienced a similar problem and could give me a hint. I have RSU 0801 applied on the system. Do you have an ESM (RACF, VM:Secure, etc.)? Alan Altmark z/VM Development IBM Endicott No, there is no ESM only basic z/VM authorisation. Meanwhile we opened a PMR and got already a fix. The reason was that the userid field was not padded with blanks to lenght of 8. The fix is working well and we are waiting for the APAR/PTF.

CSE and shared directory
Dear all, I am working now, thanks to Kris, with SysAffin in the Directory. In principle this works fine but I have now an issue with the DISKMAP utilit y. The report run on one system shows space of the disk as free where a SysAffin is coded for another system. IMHO this will lead to confusion when somebody who is not aware of the SysAffin is editing the directory. He can by accident assign such space t o a minidisk in the meaning that this is an empty space. Is there a way to mark such areas as alloced? Best regards, Florian
Switching System Users DISKACNT and EREP to other ids
Dear all, Is it possible to switch the functions of the system userids such as EREP or DISKACNT to other machines without IPL? As far as I know those names are defined in the system config file of the z/VM instance. Is it possible to change the values stated there on the fl y? Best regards, Florian
CSE and VMSERVx
Dear all, What is the right approach to define VMSERVx machines to work in CSE? When the directory is shared and the names of those machines MUST be the same on all the z/VM instances there is a conflict since they use all the same minidisks. I couldn't find too much information about this. Thank you in advance. Best regards, Florian
Re: CSE and VMSERVx
Kris, thank you for this info. But isn't it the case that e.g. DFSMS/VM need th ose SFS servers and if so, I thought the name MUST always be the original one . If this is not the case than fine. Does it mean that the DFSMS an be run from other SFS servers as well? Best regards, Florian
Re: TSAF - Supported Links
Hello Kris, Thanks for that information. I will have a look on ISFC. First, I have to get me some CTCs ;-) Best regards, Fox
