It is long established that the zSeres processors are not the fastest on the market, far from it. What you gain by running on zSeries is extremely fast internal communications with Hipersockets and Virtual Switch, high I/O bandwidth (FICON and SCSI disk support) and the economies of scale of being able to run multiple middleware machines with only the license cost of the zSeries CPUs. Running java programs is always cpu intensive.. 1 x86 CPU is _much_ faster than an IFL (on our z800), so to migrate 10 x86 to 1 IFL is not the best idea if you have heavy cpu loads. I have never seen that extremly fast i/o: an x86 can do that also with a storage server.., so if you don't have thousands of users with thousands of opened files x86 will be faster (the same goes to HiperSockets: it's nice, goes with memory speed, but at the end you need a cpu to do something with the sent/arrived data :) I think zSeries may be faster in concurrent operations.

Re: LPAR only Linux
I don't agree with you: Why to have so many penguins? Linux is a multiuser multitask O/S, and works nice, so there is no need put every application to different O/S. 1 IFL: the processor speed is the mainframe's weekness so having more VM+kernel+... overhead is not a good idea. We have here big LPARs for production systems and some with small storage to test kernels, distributions, etc. Yes, there are some good reasons to choose VM, but only if you have special needs.. (or just our shop is too simple, and I'm a bit narrow-minded :) Linux on 390 Port LINUX-390@VM.MARIST.EDU írta 2005.07.09 21:41:21 időpontban: In some ways, running VM on the IFL can be considered a cost savings. First the costs: z/VM 5.1 is $25K one time charge (list price...your business partner may charge less). Then about $5,600 per year, starting in the first year for maintenance. 4-6 disk packs (3390-3) 20MB or so for real memory. Takes a small amount of support (can easily contract it out if necessary). Now for the savings... Each LPAR takes some real memory. With VM you only need one LPAR. If one Linux image isn't being used, under VM the memory can be used by other images. With LPAR, well, without an IPL, the memory sits there idle ($80K per 8 GB for memorybig cost savings). If you have a Shark type dasd, then disk sizes can be any size you want. VM can do this with any type of disk device with minidisks. So if you only need 200 MB for a Linux swap disk, you don't have to dedicate an entire volume if you can't create a 200 MB disk. With VM, you get vdisk support (Take that!...LPAR) Create the swap disk in memory. Doesn't take any space unless it is used and then it is the fastest thing alive. If you have FlashCopy, without VM, you have problems using the duplicate volumes without creating another LPAR and backing things up there. With VM, there are better or I should say easier ways to handle duplicate volumes. Tape drive sharing in VM is a breeze. With LPAR, it can be done, but it seems to me to be harder. The more Linux images you want, the more you need VM. Linux test systems? Easy in VM. Linux development systems? Easy in VM. Dedicated Linux images for certain workloads? Easy in VM. And easier to tune and define priorities. Central console management is easy in VM (doesn't require chargeable software, just use PROP). Console automation also. Speaking of performance, performance tools, such as from Velocity Software, can be well worth the price. Nothing similar for a Linux on multiple LPAR shops. This may be just wishful thinking, but the z/890 that was just delivered to us this past week...I expect the run the IFL side, with multiple Linux images, totally lights out. Of course this is with a Shark 800 and and IBM VTS for tape. Disclaimer... I'm a VM bigot for the last 30 or so years.

SAP has no limits when we are talking about HW needs :), but we need the no downtime feature of the z/Series. The company has here mainframes since the punch card times, MVS production apps designed to run in this environment. Since that times Intel grew up, (and to tell the truth, many mission critical apps are running happily on such machines too, maybe more than on mainframes), new application developers do not care about cpu cycles, but at the end, the user wants short response time.

Some problems really *do* need big monolithic LPARs (although that's where I start to think that it's probably the wrong platform for the app unless it really is written to exploit zSeries hw features). Most don't, and managing LPARs is a LOT more expensive in people time than managing virtual machines under VM. Computer capacity is a lot less expensive than humans these days.

It is not an I/O device and so doesn't use the SAP. Data is moved synchronously using the CPU. That is a surprise. You mean the user CPU is doing this and not a SAP? That would be a reason to choose the OSA way in a cpu constrained environment. The SAP isn't used when bouncing off the OSA, either, since the card handles the DMA transfers itself. Right, so only the OSA gets a workout. For crossing LPAR boundaries, HiperSockets gives better performance than bouncing off an OSA. So it is the fastest, but what about costs? It uses an awfull lot of real. If you're worried about SAP utilization, your fave performance monitoring product will report on it. I have VM PTK, I can't find about SAP utilization. Where do I look?

If you're interested in trying it: Download the c source program file, mount.cifs.c, from url http://us1.samba.org/samba/Linux_CIFS_client.html the link called: Source for cifs mount utility on sambaweb Download the man page file, mount.cifs.8, from same url, the link called: man page for mount utility Compile the c program with command: make mount.cifs creating executable binary: mount.cifs Copy executable mount.cifs to /usr/local/sbin/ And copy man page to /usr/local/man/man8/ -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
smbmount question
Hi! smbmount works strange for me: when I mount a winxp share and walk into a folder wich contains 484 files, and I re-read it in mc some files disappear. Noone is writing in this folder. I want to tar some files, but: tar: /mnt/xx/data1.txt: file changed as we read it ...and when I repeat the tar command I get this message for the same or another files... the created .tar file is always different from the previous ones: contains different number of files. ?? -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
S.O.S. - disk full
Hi! The root filesystem seems to be full, but it's NOT! We have 2.4.19-3suse-SMPkernel and a 2G disk for /, about 1G free (du tells me, and I'm sure), and the /var or /tmp is also less then 100M If I free some disk space with deleting files, then the free space will be used for something. We are running 24/7 system so I'm not able to reboot my linux every day. Now this is 2nd time. When I had this trouble 1st time (Thursday), and I umounted some nfs imports the disk space restored. Fsck didn't reported any corruptions. Wow.. now from an another linux (slesl9 2.6.5-7.97-s390x) I deleted about 3GB from an nfs with mc, and then the free space on / was 0%!! I umounted it, and now everything is O.K. again! I can't repeat this error. I'm really confused now... I'm sure we didn't change anything in this linux... Any ideas?? -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: S.O.S. - disk full
We have 2.4.19-3suse-SMPkernel and a 2G disk for /, about 1G free (du tells me, and I'm sure), and the /var or /tmp is also less then 100M This sounds as if you deleted a file while a process was still accessing it. In that case its directory entry will be deleted while the allocated disk space will only be freed after the process closed the respective file handle. When you are deleting files from /var and /tmp, make sure that you stop the process accessing it first. I'm not deleting files from /var and /tmp... and what is when I'm DELETING from an NFS file system and then _MY_ root fs gets full?? When I mount the disk in an another Linux (LPAR) with -ro, then I see the correct disk usage. You may also want to find out why a process is generating so much data (check error logs, etc.). no error logs, no kernel messages... nothing. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: S.O.S. - disk full
I'm not deleting files from /var and /tmp... and what is when I'm DELETING from an NFS file system and then _MY_ root fs gets full?? If you can, try to restart the NFS service and see if the situation improves. If that doesn't help, try restarting some of the other services running on your system. Now, I'm not allowed to stop NFS. Later I'll do that, but it doesn't helps: the problem will come back. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: S.O.S. - disk full
Thanks for the ideas, I'll test it. Now we shut down that linux and we will test it. One other thing I still really don't understand, that what can happen to a suse9 running only it's daemons (what default installed) with one nfs directory mounted (on /mnt), when I delete from that nfs about 3GB. - I've earlyer also experienced that deleting subdirectories with mc sometimes don't works well: mc don't deletes some files, and he will get an error when tries to delete the directory. It happens only with NFS mounts. - But the main question is, that deleting from an NFS mount how can make the root fs full??? -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
netstat, /etc/hosts
Hi! I have suse9 and suse8. Internal ip adresses are resolved with /etc/hosts, not nameserver. In suse9 the netstat can find these hostnames, but in suse8 it doesn't works, except when I write ::: prefix to every IP address in the /etc/hosts file! Why is it so, and how can I shut down ipv6??

Re: SLES9 installation problem - again
Linux on 390 Port [EMAIL PROTECTED] rta 2004.10.21 11:56:07 idpontban: Hi Vic, Thanx for your response, but OSD and OSE are valid for the TYPE paramter. Only OSA and OSAD are valid for the UNIT paramter. I'm really not a z/Hardware expert, but if you really have OSA-_EXPRESS_ then normally you need qdio driver(3) not lcs (2), and qdio driver should work. You did not gave us information what happened when you choose OSA-Express... As I said, this worked fine in SLES8. Also ^c does not work (at least from the HMC). Gadi If you want to have a shell, just simply select option 0 (no network) in the main menu, so you can do a 'dmesg', etc..

linux clock
Hi! Who knows how works the system clock in a linux running on a z/800? On a PC he reads the date and time from the CMOS (once), and then the kernel is generating the correct time. But how works this when we are running in LPAR mode, and 1 IFL is shared between LPARs? He gets timer interrupt? always, or when one LPAR is under heavy load the others time slows down?
