New Performance White Paper: z/VM 6.2 Live Guest Relocation with Linux Middleware - Various Workloads
z/VM 6.2 Live Guest Relocation with Linux Middleware - Various Workloads IBM Information Center http://pic.dhe.ibm.com/infocenter/lnxinfo/v3r0m0/topic/liaag/l0lgr01_2013.htm developerWorks http://www.ibm.com/developerworks/linux/linux390/perf/tuning_vm.html#grel2 The second of a series of papers, this paper discusses the live guest relocation feature of z/VM 6.2 and focuses on how the relocation characteristics change at the workload level and how different workloads (Java™, File system, OLTP Database workloads) are affected by the relocation process. In addition, it analyzes how a live guest relocation of one workload can remedy a CPU constraint situation.

FW: RHEL 6.3 (non-)install on z/VM 6.2 at RSU6203
Posted this to the VM listserv; thought I'd better post it here, too: From: Chase, John Sent: Thursday, May 23, 2013 10:50 AM To: 'The IBM z/VM Operating System' Subject: RHEL 6.3 (non-)install on z/VM 6.2 at RSU6203 Hi, All, Trying to install RHEL 6.3 on z/VM 6.2 at service level 1301 (RSU6203). About midway through configuring the DASD in the VNC session, the installation program goes into a death spiral, aka hard spin, aka 100% cpu loop. We did not have that problem on the other CEC, where we installed RHEL 6.3 on z/VM at service level 1101 (RSU6201). Both CECs have a single IFL on which z/VM is running; no GP CPUs in the z/VM LPARs on either machine. Both CECs are z114s. Any suggestions what to do besides give up?

New Performance White Paper: z/VM 6.2 Live Guest Relocation with Linux Middleware
z/VM 6.2 Live Guest Relocation with Linux Middleware Version 6.2 of the IBM® z/VM operating system introduced the concepts of a z/VM cluster and Live Guest Relocation (LGR). This project shows the impact of live guest relocation on a Java application and gives recommendations for configuring z/VM systems in order to optimize it.

Re: best way to set up alternate ipl packs on z/VM 6.2?
This is the Linux forum, you should go to the VM lists for this kind of question. Hint: PUT2PROD goes to the RES -Original Message- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of Collinson.Shannon Sent: Thursday, August 02, 2012 9:01 AM To: LINUX-390@VM.MARIST.EDU Subject: best way to set up alternate ipl packs on z/VM 6.2? In z/VM 5.4, we had two set of packs (a set consisting of a res pack with the code on it + a spool + a page volume) that we'd alternate between as we brought up different levels of maintenance. We'd IPL off of the res pack for a set and it'd pop in the single spool and page volumes associated with it--since we only need a single spool volume and we don't really care what's on it from before the IPL, this seemed to work pretty easily to switch between levels of code. But either we need to add another volume to our sets now, or I'm doing something funky with z/VM 6.2. I looked at this layout and put in my best guesses: RELVOL/620RL1 - looked like code, so I used my res pack here RES/M01RES - actually appeared to contain lpar-specific data, so I thought it wouldn't change and put an lpar volume name here When I first IPLed, though, it wanted that lpar-specific (RES) volume, which I'm sure you guys all knew from the start. Should I use a 4-volume pack set--one release, one res, one spool and one page--now that we're going to z/VM 6.2? or can we do one release volume for the release, period--maybe that never changes while we're on 6.2--and just use 1 per release + the original 3-pack set? Does anyone else on z/VM 6.2 do the volume-switching for code method we're using who could perhaps recommend something? Thanks!

Re: best way to set up alternate ipl packs on z/VM 6.2?
If you don't need to run the alternate volume for long, you can live with a 1 volume (3390-9) RES pack, with spool and page on it. I built one to be able to IPL something other than our production systems and use multiple VMs in that system to COPY our DASD (VM and MVS) from one DASD subsystem to another. Later I even used a copy of that to do some DDR restores on a very separate system. My current RES pack even has an alternate CONFIG file that uses areas on the production RES pack for PAGE SPOOL for a Disaster Recovery scenario. /Tom Kern /on contract to US Dept of Energy /301-903-2211 (Office) /301-905-6427 (Mobile) On 8/2/2012 09:01, Collinson.Shannon wrote: In z/VM 5.4, we had two set of packs (a set consisting of a res pack with the code on it + a spool + a page volume) that we'd alternate between as we brought up different levels of maintenance.

Re: z/VM 6.2 LDAP Question
Dear Dave, Yes indeedd, that is correct and when I read your answer thought I would had forgotten to load the BFS. However I checked with the original BFS (VMSYS). This specific file is also not there. So I will add that file in the LDAP-BFS load exec. Hope that this will solve the problem otherwise I will open a PMR.

Re: z/VM 6.2 LDAP Question
Dear all, After investigated this problem, it turned out that this is indeed an error. In the file LDAPSRV LOADBFS the message catalogs for US English and Kanji for this new component Advanced replication are missing. Those catalogs are the files gldrmsgs.cat and gldrmsga.cat. Loading them manually into the BFS (via LOADBFS utility) is working. I will open a corresponding PMR at IBM.

Re: z/VM 6.2 LDAP Question
Hi, Florian. The LDAP server provided by z/VM requires that it's message catalog file be stored in the BFS and not just on TCPMAINT's 591 mdisk. Here's what the manual has to say: The LDAP server requires use of the OpenExtensions Byte File System to access the LDAP server message catalog files and to store the schema backend and other database files associated with the LDBM or GDBM backends. The message catalog files are installed by default in /../VMBFS:VMSYS:ROOT. The working directory in which the LDAP server creates its schema and other database files defaults is /../VMBFS:VMSYS:userid/, where userid is the user ID of the LDAP server. I think this is because the LDAP code in z/VM is a port from z/OS, where it uses the USS-HFS to store its files in. Good luck.
