Let me show you the numbers on a beer coaster then... I worked with Terry on his setup and recommended that in this exceptional case it would make sense to put a gravel bed next to the road to slow down the penguin with no brakes It turns out their application had a bug/failure in that it had apparently an endless demand for memory in some situation. Since VDISK is fast, you can fill it up pretty quick - at 40 MB/s your 2G VDISK is full in a minute. But filling up the VDISK did not hurt z/VM, it just made Linux give up when it ran out of swap space. And that hurt their application (probably the ungraceful shutdown required journal recovery etc of a large disk, etc). If you do the math, you will see that a penguin with intention to kill itself could also fill a 2G real disk in 10 minutes or so. In this case that was enough because they were sitting next to it during the test. When you don't expect it to happen, you will not be there in time to rescue the penguin. So I conclude: when the memory requirements of the application exceed your planned capacity just a little (say less than the swap space you set up to support Linux memory over commit) then VDISK will do fine. It does not hurt z/VM and it avoids people complain about the sudden slowdown. When Linux needs way more than planned, it will fill up swap space (whether VDISK or real) and the Out-of-Memory Killer will stop vital processes during the crash. The only advantage of the real swap disk is that it postpones the moment of crash with an hour and costs more money. Not a hard choice for me. Tuning by opinion and fear rarely is cost-effective.

Re: SWAPGEN
Hi Barton, Thanks for the information. I will have two VDISKs for my z/Linux guests already. I have found that when a z/Linux guest at least with my workload starts to use SWAP it plows through it in no time so the extra real disk for swap was to slow this down so that I could react quickly to head of off running out of SWAP. In some cases with some of my Oracle workload by the time I received the alert that the second VDISK was being used it would have already been used up. My paging subsystem is pretty robust as it stands and I do very little paging so far.

Format a SPPOL VOLUME on First IPL

I think that the only place they should be employed is in a lights-out center. If the system does the start without prompting the operator, it is difficult to keep service machines off in a problem situation.

Copying one z/VM to another using DFDSS
Hi I want to copy my test system over to another LPAR. I want to be able to IPL the new system with an updated SYSTEM CONFIG file and the USER DIRECTORY. What is the best way to do this? I figured I would do something like: 1. Create a new SYSTEM CONFIG file with the changes that reflect the new DASD device addresses, such as the SYSRES, SYSSPL, etc. if applicable. 2. Create a new USER DIRECTORY with changes that reflect the new DASD addresses. 3. IPL from SYSC console and specify the new SYSTEM CONFIG file that matches the new RES volume serial and the other volumes for the new system I am not too sure of how to load the new USER DIRECTORY. Can I create another one on the RES pack that is being copied and then specify that USER DIRECTORY at IPL time? Not sure! BTW, I am using DFDSS to do a full volume copy and a restore.

Re: SMSG to RACFVM to do SMF SWITCH
Hi I was able to issue the command as you pointed out but received an error when it tried to autolog the RACFSFM machine. When I look at the SMF CONTROL file I see the following: CURRENT 301 K PRIMARY 301 K SECONDARY 302 K 1 LVA1 CLOSE 001 SEVER NO 0 RAC Note that RAC should be the name of the machine (RACFSMF) to be auto logged but whenever I try to change it to RACFSMF it truncates back to RAC.

SMF CONTROL FILE FOR RACFVM
Hi I asked this in another thread but I thought it might be better in a separate one for archiving purposes. Anyway I am trying to get the RACFSMF SMF switch process to work. I modified the SMF CONTROL file to specify the correct LPAR and added the RACFSMF machine name at the end of the file to let RACFVM know he is to autolog RACFSMF to handle the SMF switching and such. The problem is that when I try to change the default of RAC as the machine to be auto logged it truncates all but RACF after I hit the enter key. Is there an issue or am I doing something wrong here?

For instance, if you had a VDISK at 160 defined in your directory, you could do SWAPGEN 160 nblocks ( REUSE Where nblocks is however many blocks.
