Re: COPY RDR to another machine
No, TRANSFER is what it says, the object is transferred, not copied/cloned/xxx As you do not have the privilege to use DIAG D4 to set the origin, you could create a service machine that has the privilege, it could perform the copies of the spool files x times. 2009/9/22 Gonen Shoham gone...@sapiens.com TRAN RDR does it ok, but deletes the file from my reader.

For an exact copy: SPXTAPE to dump the RDR file to tape, then restore on the target system. If you only need to set the origin userid: use Diagnose D4 to set the alternate userid of the copying user to the sender's userid. As this is cheating, one needs a special CP class to be able to use Diag D4; and if an ESM is installed, extra permissions are required in the ESM (for RACF that is in class VMBATCH).

Can someone suggest a better way to replicate RDR file from one machine to another with keeping the original user ? many thanks -- Kris Buelens, IBM Belgium, VM customer support -- Kris Buelens, IBM Belgium, VM customer support
Re: 回复： Does OSA Express2 Ethernet su pport zVM layer2
Greetings, I saw this post and would like to get some verification on running both layer 2 and layer 3 on the same OSA. So we can now have say a z/VM running Linux guest on a layer 2 to an OSA along with a layer 3 TCP stack on the same z/VM using the same OSA? Would we be able to also have other LPARS either z/VM or z/OS share this same OSA with layer 3 as well ? From my understanding you had to have OSPF to share the OSA’s with other LPARS ( mainly with the z/OS ) We currently have the new Z10 box Thanks Russell Gendreau Time Customer Service, Inc. 813-554-2064 From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Anson Sent: Monday, September 21, 2009 8:28 PM To: IBMVM@LISTSERV.UARK.EDU Subject: 回复： Does OSA Express2 Ethernet support zVM layer2 Ronald, Thanks for your information!

But what won't work on a z900, is sharing the osa with layer 2 and layer 3 traffic. As I recall, the first to connect to the OSA could set the mode (2 or 3) and all other shared connections have to use the same mode (just like the portname). The restriction got lifted with z990, there you can use the same shared OSA, mixing layer 2 and layer 3 connections.

Yes, you can run both and they can even talk to each other. In the distant past, layer 2 and layer 3 could co-exist, but they couldn't talk to each other, creating a problem if they were in the same subnet. That was fixed a long time ago (z990?). So we can now have say a z/VM running Linux guest on a layer 2 to an OSA along with a layer 3 TCP stack on the same z/VM using the same OSA? Yes. Note that z/VM 5.4 TCP/IP now supports layer 2. Would we be able to also have other LPARS either z/VM or z/OS share this same OSA with layer 3 as well ? Yes. From my understanding you had to have OSPF to share the OSA?s with other LPARS ( mainly with the z/OS ) Not true. If you are sharing and the OSA is plugged into an access (as opposed to trunk) port on the switch, then everyone is in the same LAN segment and therefore the same subnet. z/VM has the VSWITCH to supply the needed OSA redundancy. z/OS has OSA failover (takeover), but no one seems to use it, depending on OSPF instead to handle the outage.

Re: VM lockup due to storage typo
I don't think the analogy to a ping attack is a particularly fair one. Yes, from the perspective of an innocent third user, they look the same, perhaps, but they aren't. ??? In both cases, normal function of the innocent guest is disrupted by a force beyond it's control through no fault of it's own. The function is disrupted by a lack of shared resources available to the innocent guest due to trying to service what appears to be legitimate resource requests to another theoretically innocent guest. If the attack were made through some sort of security gate that defaults to closed state which the sysadmin had accidentally opened and left open, I think that would be a more fair analogy. Quibbling over details, perhaps, but there is an important difference. Network floods have nothing innately to do with security states. You can produce exactly the same effect within a local segment with no outside connection, FW or any other security gates involved (misconfigure any DECnet device that boots via MOP and see what happens), so I don't see the subtle difference here -- one device banging out traffic without regard for other systems on the same network segment starves access to the other systems on the same segment, denying them the ability to function normally. Barks like a duck, swims like a duck, it'll do for duck soup, as a friend of mine says. But, as you say, let's concentrate on fixing the problem, not blaming the symptoms.

The reason is that I need to TRAN the RDR many times . No. A spool file exists only once in the system. That will drive the design of your spool file sprayer application. If you want spool files to appear as though they are from someone else, then you must have the authorization to use DIAGNOSE 0xD4 and use it as Kris showed. If your application is willing to do some more work, then it can use DIAGNOSE 0xF8 to establish and determine the origin of the spool file. While it doesn't require class D, it nonetheless requires SETORIG authorization in the sprayer's directory entry. (By the way, Diagnose 0xD4 can be moved to some other privclass, e.g. N, and given to those who need it, without giving all the power of class D.) Virtual machines are not allowed to tell lies about themselves unless they are authorized to do so. Alan Altmark z/VM Development IBM Endicott
Re: 回复： Does OSA Express2 Ethernet supp ort zVM layer2 mode
The earlier OSAs had special code to enable IPv6. I (and many others, I’m sure) screamed at IBM that having them in the loop of OSA firmware protocol support for every possible protocol that someone was going to need was unsustainable, which resulted in the layer 2 support. If you’re doing this long term, then get layer 2 support working. If you just need to throw a IPv6-enabled guest up for testing purposes, you don’t need to get layer 2 working for IPv6 if you have up-to-date OSA microcode. Wrt to dedicated vs VSWITCH, use VSWITCH if you possibly can. Isolates you from the weirdnesses of the various OSAs, and the impact of the extra code is minimal. Actually, I was also trying to configure this linux guest using dedicate OSA devices in stead of vswitch. Does it still need layer2? Thanks! Anson Y.
Re: Storage Management Enhancement Ideas
The partition is the easy part, just follow the model of the DUMP space in spool. But how, if you cannot even get a command entered by a logged on user, are you going to be able to make use of it? I think that the idea of putting the collar on the runaway process or guest has to be solved first. Then, it might be possible to take corrective action from already existing userids such as OPERATOR, obviating the need for partitioning.

For the purposes of discussion, let us consider that following enhancement: I don't like the idea to use only a subset of your paging capacity for part of the workload. It's not just about space but also about throughput. This is imho a very complicated approach to exclude some (small) important users from an OOM killer. The real question is whether you can do an OOM killer at all and achieve something useful by doing so. Most performance tuning gets harder when you split resources and consumers in different groups and manage them separately. Sharing is easier with large numbers. And does not address the core issue: At some point, there is a shortage of resources. How should CP respond? o Deny the request? o Wait for the resources to be available? o Steal the resources from someone else? You can partition and reserve all the resource you want, but eventually you run out. Alan Altmark z/VM Development IBM Endicott

Now THAT would have exposed the problem. :-) Actually, he already tried that and the result has been this discussion. Regards, Richard Schuh I'm sure that there are a couple other ways of preventing the problem, like IPL'ing the machine first and doing a Q V ALL to see what resources you really did ask for, could have stopped the problemif the Systems Programmer did it.

As my understanding, it should be different case, right? The choice of layer 2 or 3 depends on how you configure the qeth driver. See the Device Driver book on DeveloperWorks for details on that. When using a VSWITCH, the guest must conform to the type of VSWITCH (IP=layer 3, ETHERNET=layer 2), as the VSWITCH does not support both kinds of vNICs at the same time.
