R/3 kernel question

Hi gurus
i have a question.
We had a problem running /exe/dp ...its saying some errors. We did a copy of the whole kernel from production (prd) to the test system (tst). The PRD has a kernel support package level like 2307 and the TST has a lowest support pkg level. After copy of the PRD kernel to TST we were able to run DP executable without problems. Before we copied the PRD kernel to TST we had a successfull backup and after copying the kernel we had fails back up because BACKINT was broken or something and Prole sayd that the versions are not compatible. After the other team restore the old BACKINT it was ok - the archive was ok. I have this question. Is it possible to be from the copying of the kernel and is it becouse we actually put in the TST system a DP executable which is from PRD (highest support pack)? 
Thanks

Hi,
Try using latest kernel...
If it fails switch between old and new kernel during installation...
Regards.

  • Real Time kernel questions

    I decided to compile myself a new kernel using a PKGBUILD from AUR, which contains Ingo Molnar's real time patch. I know that there are some entries int the wiki about this (Kernel Compilation with ABS, Custom Kernel Compilation with ABS, Kernel Patches and Patchsets), but they don't answer all of my doubts.
    The major question is related to my graphic card's drivers. I'm a happy Radeon user using fglrx proprietary drivers. At the moment they are working fine on a vanilla kernel form [core], the problem is whether I would have to do some voodoo to make them work on a rt-kernel? Now I know what is written in wiki about installing Catalyst drivers on a custom kernel, but when on Mandriva I tried to install 8.1 on my rt-kernel, I had to do some tricks and recompile fglrx to make it work. Does anyone tried installing Catalyst drivers ver. 8.2 on a real-time kernel from AUR?
    Another thing: I have a .config file from the previous rt-kernel. Would it be suitable for 2.6.24?
    Finally, I recently read about grsecurity patchset. Did anyone tried it on Arch, especially on a real time kernel? Any problems?
    Waiting for suggestions

    I'm using one on my Mandriva 2008.0 and didn't notice any slowdown.
    broch wrote:second: I use grsec (or RSBAC) kernels.
    grsec will not work with anything messing up with memory (even Kolivas patches in past had issues with grsec). This can be fixed but then what is the point of enabling hardened kernel with disabled features?
    I simply patch vanilla with grsec.
    Remember that some pax options are incompatible with X (all explained when option is selected, so no way to make mistake)
    finally it works well lowest overhead, best speed and easies to manage among kernel hardening patches (I do not count Apparmor, as this is rather limited tool)
    If I understood you, then it's a choice between real time and more security, right?

  • Arch Kernel Questions

    (This is a really low-priority set of questions.)
    I just wanted to know what some of the differences between the main stable 2.6 kernel and Arch's 2.6 kernel are. I'm not a fan of compiling kernels, so I'd like to know what decisions are made for the default kernel.
    Let me be more specific;
    1. linux-2.6.26.1/Documentation/java.txt: apparently, native support for java binaries is planned for the kernel. Will this be reflected in Arch's kernel as well?
    2. Besides x86, what architectures are supported by the Arch kernel (linux-2.6.26.1/arch)?
    3. Does the Arch kernel support virtualization by default?
    4. Which drivers (if any) are excluded from Arch's kernel (linux-2.6.26.1/drivers)? (If any, why?)
    5. Which filesystems are supported by the Arch kernel (linux-2.6.26.1/fs)? In the install, there are only 5 filesystems available so I'm guessing it's just those 5?
    --- And any other major differences that are worth noting.
    Thank you for reading!

    there is a bug with xen in kernels newer then 2.6.18.
    arch's kernel is as vanilla as the stable release is from what I gather. Other then a few patches and some config changes. Arch tries to stay as close to vanilla as possible with all it's packages. just do a diff between the two configs.

  • Kernel Questions

    Just a couple questions about kernels.
    1. What is the best (in your opinion) kernel patchset?
    2. Is there a system-specific kernel config generator? (Takes the fun out of kernel compiling, I know )
    3. I compiled a kernel without a PKGBUILD (gasp) and want to get rid of it. How would I go about doing that?

    I can't comment on the two first questions, as I prefer configuring the kernel manually, and I've only been using vanilla sources for the last couple of years. The third one is easy, though.
    The kernel image is usually installed as /boot/vmlinuz or something like that, and whether or not an initial ramdisk was installed depends on how you compiled the kernel. If you used mkinitrd, mkinitcpio or something like that, the image is likely to be placed somwhere in /boot. If you compiled the kernel using only the usual make, make modules, etc, you probably don't have any initial ramdisk to remove. The kernel modules are placed in /lib/modules/KERNELVERSION-KERNELNAME. You just have to remove the mentioned files and folders in order to remove the kernel.
    NB! Unless you're comfortable with using a livecd and a chroot-environment to fix a broken system, I would suggest that you don't remove the kernel until you have a working replacement ready.

  • Arch Kernel Question

    So...  I guess I'm not a Linux 'newb' per-se, but I have a Arch newbish question.  I've been a Gentoo guy for quite a while and like the system.  However I have a couple new Arch boxes now that are just less headache to manage.  My question is that I'm in the early stages of building a LiveCD / LiveUSB for personal use and I'm trying to decide what distro to use.  The reason I'm leaning towards Arch is the larch stuff that is available.
    Long story short, my question is -- within Arch are kernel upgrades just part of a system update (I believe they are from what I've seen) or is there a facility, like within Gentoo, to hold back a particular kernel?
    My next question is somewhat similar -- if I'd like to run a vanilla kernel and maintain it myself how does that affect system updates?
    The problem I see is that I need a lot of customization in the kernel, and I need it not to be bleeding edge.  A lot of this has to do with the tools stability so I want to be sticking pretty hard to a kernel once it's implemented and I don't want it to be just magically updated.
    Thoughts, comments, suggestions?
    Kind regards,
    --windexh8er

    Cool, thanks!  Is there any way that those modules are tied as dependencies to the kernel through the IgnorePkg?  Wherein if I am ignoring kernel updates it will also ignore any modules that are in the package system?
    Thanks for the quick reply and welcome. 
    --windexh8er
    You're going to have to explicitly block anything that you don't want to upgrade, including modules. Of course there will come a time (major kernel version bump) that stuff simply won't upgrade anymore. In that case, pacman will fail with errors.

    Thnaks a lot, Martin

    I upgraded with only 4GB (2x2GB). than added 4x4GB.
    Everything was fine. But I was experiencing some issues, I was trying lots of little programs.
    I'm a new Mac user, so I was just trying to find out what works for me and what not.
    So then I wanted to reinstall Lion, clean, because the computer got slow, and I wanted to get rid of all the accumulated junk.
    I couldn't reinstall Lion because of the error message saying that "it couldn't download needed files to complete the installation".
    So I ended up installing Lion on an external hard drive and clone it to my Macintosh HD.
    Seems to work alright, it's fast again, but I'm still getting the grey screen every now and then.
    Hope this makes sense...

  • Convolution kernel question

    Hi, i've been wondering why kernels of smoothing and sharpening function are matrices with some of all elements is 1 ?
    E.g:
    Smoothing:
    1/9 1/9 1/9
    1/9 1/9 1/9
    1/9 1/9 1/9
    Sharpening:
    -1 -1 -1
    -1 9 -1
    -1 -1 -1

    Do you mean "the sum of all elements is 1"?

  • Oldschool K6/200 Kernel Question [SOLVED] BUT MORE QUESTIONS

    Ok so I've been playing around with the Idea of switching over to linux for awhile now. I've been told that Arch is a great distro to start learning on. That Being said I have an old calibri with a AMD K6/200 running an old red hat distro my father used to use. Well I looked through the documentation for ArchLinux and found this
    "Arch Linux is optimized for the i686 processor and therefore will not run on any lower or incompatible generations of x86 CPUs (i386,i486,i586). A Pentium II or AMD K6-2 processor or higher is required. x86-64 architectures are also officially supported."
    Posted in the "Official Arch Linux Install Guide" Great it should work on my computer. So I download the archlinux-2008.06-core-i686.iso burn it and boot from it.... says wrong Kernel for my CPU. I'm kinda stumped any help?

    Well thank you all very much. I think i'm going to try all of your ideas out. Possibly starting off with Xubuntu as it seems to be an easier transition. I currently have 3 of these machines and it seems this will be an enjoyable challenge. xubuntu's wiki does not seem to be as user friendly as this so it's going to take awhile for me to find the proper kernel lol. here goes nothing..... by nothing i mean XP
    EDIT: Also the current Kernel of Xubuntu says that it supports 1386-class processors. I guess I'll find out sooner or later. Thanks again
    P.S I'm getting the alt install anyway... hope installation isn't going to be a hassle lol

  • MSI Wind kernel question

    Is there any Arch package of kernel compiled for Wind?

    Quote
    I downloaded CPUz but it shows Specification as 1.6Ghz and core speed as approximately 926mhz.    The power on button changes from blue to orange, but other than that i have no idea if it is OCing.
    Yes, you're overclocking. The CPU only runs at full speed when its under full load (to save power). Normally when idle, the CPU speed drops to 800mhz, so the fact that yours is idling at 926mhz means the OC is active. Put the CPU under heavy load, using something like SuperPi or Prime95, and you'll see the CPU speed will exceed 1600mhz.

    I need to run a preconfigured Vmware VM on one of ours Enterprise Linux servers. I've already installed VMware-Player-3.1.2-301548.i386.bundle on the machine, no error message, but now when I try to run vmplayer I am getting the following message:
    before you can run vmware, several modules must be compiled and loaded into the running kernel:
    kernel headers 2.6.9-78.0.0.0.1.ELHugemem
    kernel headers for version 2.6.9-78.0.0.0.1.ELHugemem were not found...
    I've already searched both on google and on Oracle website for a package containing this version of kernel headers, but didn't find them.
    I've did an up2date -i kernel-devel, some kernel headers got installed, but it seems they are at the wrong version:
    [root@dscdap01 ~]# ls -la /usr/src/kernels/
    total 24
    drwxr-xr-x 4 root root 4096 Nov 2 06:59 .
    drwxr-xr-x 4 root root 4096 Dec 4 2008 ..
    drwxr-xr-x 17 root root 4096 Nov 1 09:42 2.6.9-89.31.1.0.1.EL-hugemem-i686
    drwxr-xr-x 17 root root 4096 Nov 2 06:59 2.6.9-89.31.1.0.1.EL-i686
    As far as I can see, I have two paths for solving this:
    1: update the running kernel to 2.6.9-89.31.1.0.1.EL-hugemem-i686 - in order to do that I'll have to restart the machine, which is quite risky because this is an important machine used for many projects and I do not have physical access to it; in case something goes wrong I'll have to make an SR to the GIT guys, and pray for a quick resolution
    2. find this particular version on kernel headers (2.6.9-78.0.0.0.1.ELHugemem), install them in a non-standard location and then point vmplayer installer to that location in order to compile and plug them into the running kernel
    Questions:
    - If I choose the 2nd path:
    -- where can I find this particular kernel headers version?
    -- after vmplayer compiles them, will it request a machine restart, or plugging them into the running kernel will be possible without restart?
    -- I already did an up2date -u, so the entire system excepting the running kernel is updated to whatever is in Oracle's internal repositories. Will this conflict somehow with an older running kernel and modules?
    -If I choose the 1th path (update the kernel itself and reboot the machine):
    -- will then vmplayer be able to compile and install the kernel modules without asking for another restart?
    Thanks a lot for your feedback.
    Any idea is appreciated, even pointing me to someone in Oracle that might help (I am an Oracle employee) would be useful.
    Regards

    Thanks for your reply Joe. I did not realise that I shall search for the package name without "ELHugemem" part since the headers are probably the same. Please correct me if I'm wrong here.
    So I downloaded the i686 package, but now I get this message:
    [root@dscdap01 ~]# rpm -iv kernel-devel-2.6.9-78.0.1.EL.i686.rpm
    warning: kernel-devel-2.6.9-78.0.1.EL.i686.rpm: V3 DSA signature: NOKEY, key ID 82fd17b2
    Preparing packages for installation...
         package kernel-devel-2.6.9-89.31.1.0.1.EL (which is newer than kernel-devel-2.6.9-78.0.1.EL) is already installed
    I am not sure if I shall do a "rpm -ivf" for this package, forcing it to install. Will this command install the package alongside the existing one, or will it overwrite it? My guess is that it will install it alongside the existing one, but since this system is an important one I would prefer to ask before doing any stupid mistake...

  • I cannot get my Mac Pro (Original) MacPro1,1 to boot with the 64 Bit kernel in 10.6.8

    I cannot get my Mac Pro (Original) MacPro1,1 to boot with the 64 Bit kernel in 10.6.8 (this is a 2 x 3Dual-Core Intel Xeon machine).
    Firmware = MP11.005C.B08 (EFI 1.2) 1.7f10 (SMC 1.1)
    Will it not  run the 64 bit kernel?
    Is there a firmware upgrade to allow this?
    Should I bother?
    It won't boot with the Key 6 & 4 method.
    or using Terminal command;
    sudo systemsetup -setkernelbootarchitecture x86_64
    Any suggestions?
    Thanks in advance...
    Eric

    Because it can't and doesn't have a 64-bit supported firmware.
    UEFI (EFI64) was not finalized and adopted until very late 2007 and introduced in 2008, by Apple, Intel, other members of EFI Group and Unified EFI.  The Mac Pro Mid-2010 was  the first time though that 64-bit mode was the default.
    Does it matter? not really. you can't install 48GB RAM anyway, while there are some improvements from 64-bit kernal.
    Also can't boot Windows 7 64-bit DVD to install properly. But you can run Windows 64-bit kernel because you have a 64-bit Xeon.

  • How do I ensure new kernel will boot?

    I have just done a 'pacman -Syu' and noticed that kernel26-2.6.4-1 is included in the updates.  I'm currenlty running Arch 0.6 with the stock kernel 2.6.3.  What do I need to do to ensure that my machine will boot with the new kernel?  Do I just run
    # lilo
    from a command prompt?  Is there something additional I should do?  I haven't updated a kernel in Arch yet and didn't see a recent post that explicitly explained it.  If I missed, please point me to that.
    Thank you.

    OK, thanks.  I'll get into 'tweaking' the kernel questions later. 

  • Post-Kernel Panic: Various questions on iTunes, mail, stability, help!

    I recently experienced a Kernel Panic on my Macbook Pro from late 2010 (2.53 ghz, 4 gb ram, 500 gb OS X snow leopard etc).
    First, a quick overview of the Kernel Panic process:
    I had a lot of stuff running simultaneously, and the system started hanging for several minutes. I then made a manual shutdown by pressing the power button, and when I started it up again, I entered the wonderful realm of Kernel Panic.
    Extended hardware test found nothing wrong.
    Disk Utility told me there were a corrupt sibling file, as well as about three corrupt record files (I think they were called that - it looked pretty generic, but unfortunately I didn't write anything down).
    I couldn't start in safe mode, a PRAM boot didn't do anything, nothing worked. I couldn't reinstall OS X, as I got a message saying there couldn't be written to my harddisk.
    I didn't have any Time Machine backup, so a very friendly collague of mine took my MPB apart, and in short transferred the contents of my harddisk onto an external harddisk. I then formatted my harddrive, reinstalled OS X, and am now in the process of putting everything back in place, as well as I can. But I have a bunch of questions and observations I'm a little worried about, and I very much hope someone can help me.
    It must be mentioned that I haven't taken the MBP online again yet; I am currently still at work and am not able to get my Mac online on the work network (it's locked). Therefore there are some OS X updates I haven't reinstalled yet.
    - I have managed to rebuild all my subfolders in the default Mail program; however, my Inbox is nowhere to be found on the external harddrive, and I can't seem to find the location of my new inbox anywhere. Is it eternally lost, or can I restore it? My extemely important mails are saved (software licenses etc), but there were quite a few mails in my inbox that are important as well and i'd like to get them back.
    - ITunes seem to have some issues with handling the import of my entire music/podcast archive (about 120 GB). If I select more than approx. 15 gb to import, it starts hanging, and I have to force quit it and retry with a smaller chunk. Is this normal, or should I be worried?
    Note: I did notice that a couple of the folders in the salvaged iTunes archive were completely empty - there's only a picture of a blank piece of paper next to it, instead of a folder icon, and the size is 0 kb. I can just re-rip the music to my library, but I am a little suspicious of this.
    - More iTunes. One of the times I force-quit it and then tried to reopen it, I got an error message saying that I couldn't open the iTunes application, because the files were locked, or the archives were locked, or something along those lines. I got quite a scare, but after restarting the mac, iTunes opened as it should. Again, should I be worried? Is this normal?
    - I am considering getting a new harddisk for the MBP, a Seagate Momentus XT 500 gb, as I am a little wary of the default harddisk after this. I figure that since I haven't put anything back in place yet, it would be the same if I had to format and reinstall OS X once more. The damage has already been done, so to speak. Would this be a good idea, or is it unneccessary? (I have ordered a RAM upgrade, so i'll be running with 8gb instead of the default 4).
    - Why did this Kernel Panic happen? I know I made a force shutdown, but why did it go so wrong? I would like to know what caused it, so I can prevent it. Couldn't it handle the extensive simultaneous processes I was putting it through (my gargantuan iTunes library was running, I was watching a video, had many tabs open in Chrome, it was hot etc)? Will the planned RAM upgrade fix the issue? Is there something fishy about my harddrive?
    I hope someone will take the time to answer my many questions, and I am very grateful for any help.

    The most important thing for you to learn from the experience is that you'll inevitably lose all your data if you don't make backups. Regard that as a certainty, not a risk. Do no more work with the computer until you have a backup solution in place.
    The second point is that your hard drive has failed and you shouldn't continue to use it. Shut down the computer now and don't start it again until the drive has been replaced.
    For future reference, familiarize yourself with FireWire target mode:
    How to use and troubleshoot FireWire target disk mode
    This mode can be used to access the internal storage device of a Mac without booting it.
    Some of your files have apparently been lost or corrupted. If you don't have backups, they're almost certainly gone forever. It's possible to attempt data recovery on a failed drive, but the more you use it, the less the chance of success. I have no experience in this area.
    As for why the kernel panic happened, that's impossible to say without a panic log, but it was most likely caused by the drive failure.

  • Questions: On NVIDIA Kernel module and install process

    Hi everyone,
    I have a PCIe 7600 GT card, and trying to get it to work in its full power.
    So far I have not succeeded, and condemned to run in VESA mode. But have one more try to do following the advisory of upgrading kernel and reinstalling the Nvidia driver.
    I have few questions though:
    - I know my kernel as 2.6.15-ARCH (from the dir in /usr/src), but in the above mentioned advisory, there were more digits after ("2.6.16.14-1"). Where in my system, I can locate those micro version numbers, if I need to?
    - My not-yet-working Nvidia driver insrtall (from [testing]) left a kernel module with "agp" in the name. Is it the way it should be, taking into account that I have a PCIe card? Or is this pointing to an install problem?
    - I have browsed the stuff in the 8756 vintage of the Nvidia driver, and noticed that there are references to X11R6 which I do not have (have an  X R7 Xorg). Which one of  the driver-install-script or Arch-PKGBUILD-file has the intelligence to place the files correctly in R6 and R7 installs?
    - The 8756 text also refers to nvidia-xconfig utility, and I did use it in my 64-bit Gentoo install. In my Arch install it is no where to be found. Again,  is this pointing to an install problem?
    Thanks,

    1.
    pacman -Q kernel26
    will give you the minor numbers
    2. no clue
    3. the 8751 driver works fine with xorg 7, so i presume the new one should work also.
    4. no clue
    as an alternative to VESA :
    pacman -S xf86-video-nv
    this will install the open source nvidia driver. It supports only 2D acceleration, but should improve your screen a lot over standard VESA.
    put
    Driver "nv"
    in your device section in xorg.conf to enable it.

  • [SOLVED]How to patch the kernel? And other questions

    Like the same user who started this thread I'm suffering from hibernation resuming troubles using kernel 2.6.38. In that thread was posted a soluttion that involves patching the kernel.
    The patch to apply is this:
    http://git.kernel.org/?p=linux/kernel/g … e3e9fc8684
    Waiting for the bug to be corrected and a new version supplied is not an option, because this laptop is my main computer and I heavly rely on hibernation.
    Here's my trouble now. I don't know if it is possible to patch without recompiling the whole kernel, or it has to be compiled with that patch applied. I have seen the archlinux's wiki guide about compiling the kernel, but found nothing about applying patches (maybe I didn't searched with enought depth).
    In case there is needed a full compilation, should I use the vanilla kernel, the Arch Linux one or any of the AUR ones (I said AUR because they're the first that came to my mind)? Should i expect a performance gain with this (apart from fixing the hibernation bug)?
    Maybe i'm just doing a bunch of dumb questions, and the only thing I need is to search deeply on the wiki. In that case, please tell me. If not, I rather get some answers around kernel patching and / or compiling questions.
    Edit: In addittion, it is possible that all this questions are just newbie ones, I don't know, but as I am willing to learn from this I will appreciate any info or documentation about it.
    Thank you.

    From the source tree (/usr/src/linux-whatever) execute
    patch -p1 < /path/to/fix.patch
    then recompile kernel from the source tree.
    Basically that consists of executing the following commands from the source tree:
    make menuconfig
    make
    make modules_install
    cp -v System.map /boot/System.map-CUSTOM
    cp -v arch/x86/boot/bzImage /boot/vmlinuz-CUSTOM
    mkinitcpio -k 2.6.38-CUSTOM -g /boot/kernel-CUSTOM.img
    and you need to add menu entry in /boot/grub/menu.lst
    -k 2.6.38-CUSTOM should corespond to /lib/modules/2.6.38-CUSTOM (replace 2.6.38-CUSTOM with the name of your module directory, name depends on the kernel version and suffix that you gave in menuconfig). Regarding kernel configuration in menuconfig - I can't help you, you could use arch stock kernel config (zcat /proc/config.gz > /usr/src/linux-whatever/.config)
    I do these kind of things this way - maybe someone else have a more elegant solution.
