Can I take my OS on kernel patch backwards?

Hi All,
I know that this is a weird question.
Can I take my OS one (or two) kernel patch backwards?
Lets say from "Generic_120011-14" to "Generic_118833-36". ? is it possiblle?
All this mass is beacuse of a testing team at my work.
Thanks!!!!

It depends on how you got to 120011-14.
If your initial install was 118833-36 or earlier and you patched up to 120011-14, then in theory you can back out the patches.
But the initial install was higher than 118833-36. Or you live upgraded past it then you can't go back.
Even if you patched past it, it would be a difficult excercise because there are a lot of related patches that rely on the higher kernel. So you would need to backout any patches that rely on it first.

  • ABAP and Kernel Patches for Upgrade and Conversion in 4.6C

    Hi,
    We are in a process of upgrade and unicode conversion for the source release 4.6C (Kernel  46D_EXT Patch 2225).
    "Combined Upgrade&Unicode Conversion Guide"  for "SAP Basis 4.6C u2192 SAP NetWeaver 7.0 application Server ABAP Unicode Including Enhancement Package 1 Support Package 01 - 06" , In Software Requirements step,  it says
    "3. Import 4.6D Kernel patch 2326 from SAP Service Marketplace according to SAP Note 19466"
    We wanted to know whether "IT IS ABSOLUTELY NECCESSARY TO GO FOR THE KERNEL PATCH 2326".  We dont have "EBCIDIC code pages" in our MDMP system.
    We need to know  becauase we are also doing OS migration from AIX to Sun and this step will add to our production downtime.
    Please advice what are the other causes we should go for the kernel 2326.
    Regards

    Hello Mr. Nils Buerckel,
    Thanks for the reply.
    We wanted to be very sure whether we should used Kernel 46D Kernel patch 2326 (As it is specifically mentioned in the SAP CU&UC guide and in SAP Note 867193, It is mentioned that  "This patch contains enhancements that are required to execute the "INDX Analysis" scan)
    OR
    Can we go for the latest kernel patch avaialable at market place? And Will the latest kernel patch also contains the "enhancements that are required to execute the "INDX Analysis" ?
    Please reply
    Thanks

  • Can i get collection of kernel patches in 1 EXE.....

    Hi,
    We found around 40 kernel patches and 20 oracle patches in service market place. Is there any option where we can get 1exe file for all 40 kernel patches(
    34 are independent & 6 are dependent) & 1exe for all 20 oracle patches?
    Where can i find patches for BRTOOLS in market place?
    We thought of installing Oracle and thn the patches, then apply kernel & its patches and then once SAPINST is complete go for BI cont 3.53 installtion. Is the sequence i mentioned correct ?
    Thanks for your valuable time .........
    Bob

    You don´t need all of them, you just need specific ones.
    SAP releases every quarter a patch set with all the actual and tested patches of the different tools, the DB independent and the DB dependent part.
    To get the newest kernel patches download
    - SAPEXE*.SAR (for your operating system)
    - SAPEXEDB.SAR (for your database)
    and then subsequently all the patches, that have creation dates AFTER both the others mentioned above.
    The BRTOOLS are in the Oracle folder of your operating system named "DBA".
    Your sequence for the installation is not correct:
    - start sapinst and install central instance
    - start sapinst again and install database instance
    - sapinst will stop at a certain point and will tell you to install the database (use the RUNINSTALLER provided on the SAP-CD and NOT the standard runInstaller)
    - patch your database up to the latest patchset and all interim patches
    - go on with sapinst
    This is all covered in the official installation guide available at

  • MSCS and Kernel patches: Can someone please refresh my memory?

    Greetings,
    We run 4.7 Ent on a 2-node MSCS Cluster (SQL).
    I need to do a kernel upgrade, but I have forgotten the precise distribution of kernel files outside of the "run" directory for the cluster.
    I understand they are:
    Main Kernel Files
    shared_drive \usr\sap\<SID>\SYS\exe\run
    MSCS Files (on each node)
    local_drive \Windows\SapCluster\
    local_drive \Windows\System32\
    However, could someone please remind me which files go into
    "SapCluster" and "System32", or if you know the location, point me to an SAP document that details the kernel patch process in an MSCS Cluster (rather than a general MSCS config document which is of no use in this situatio).
    Thanks if anyone is able to help.

    Hi Tim,
    We have a productive SAP R/3 4.7 (Windows 2003 IA64 Oracle 9.2) on a 2 nodes MSCS cluster.
    In C:\windows\SapCluster
    We have the following files :
    backint.exe
    brarchive.exe
    brbackup.exe
    brconnect.exe
    brgui
    brrecover.exe
    brrestore.exe
    brspace.exe
    brtools.exe
    cpio.exe
    cpqccms.dll
    dd.exe
    dev_rout
    mkszip.exe
    mt.exe
    niping.exe
    pstat.exe
    rfcoscol.exe
    routtab.txt
    sapevents.dll
    sapgw
    sapntchk.exe
    sapntwaitforhalt.exe
    saposcol.exe
    saprouter.exe
    sapsrvkill.exe
    sapstart.exe
    sapstartsrv.exe
    sapstartsrv.exe.new
    sapxpg.exe
    uncompress.exe
    So basically the SAP cluster dlls and the brtools.
    We have also  C:\windows\SapCluster\brgui with the brgui files
    and C:\windows\SapCluster\sapgw with the standalone gateway executables
    In C:\windows\system32 we have these SAP files :
    sapmmc.dll
    sapmmcada.dll
    sapmmcinf.dll
    sapmmcms.dll
    saprc.dll
    saprcex.dll
    sapstart.log
    sapstartsrv.exe
    To update the kernel, we do it one node after the other one switching the SAP resources between the 2 nodes .
    We of course keep the same patch level in the different directories.
    Hope this helps.

  • Kernel patches

    Not too long ago I posted a request to the forums and flyspray for adding the fbcondecor patch to the arch kernel:
    http://bbs.archlinux.org/viewtopic.php?id=38966
    Quite a few other people wanted it as well. Needless to say it was turned down:
    Closed by  Thomas Bächler (brain0)
    Tuesday, 23 October 2007, 12:49 GMT-5
    Reason for closing:  Won't implement
    Additional comments about closing:  We don't randomly add features to our kernel, we like to stay as vanilla as possible.
    No problem. I saw the point. I moved on and patched my own kernel. However I got really pissed off when I saw the undervolting patch among other patches being added in the next kernel release, kernel26 2.6.23.1-7. It sure looks like features are randomly added to the arch kernel. Doesn't it?
    EDIT:
    To make this more of a constructive criticism than a rant let me ask the question:
    What is the process used by the devs for deciding what patch is added to the arch kernel?

    So because you didn't get the feature you wanted, and someone else did, that makes you mad?  I can assure you that patches aren't "randomly" added, and I'm sure if you take a step back you can agree that an undervolting patch has a greater overall benefit than a bootsplash patch.
    (-edit- Hm, upon re-reading it sounds like I'm supporting the undervolting patch. I suppose I should add that I have no use for either undervolting or bootsplash.  I could do without either, and I recognize that undervolting in and of itself can be dangerous and unstable, however the heat and battery savings shouldn't be overloooked either. 
    I don't intend to support anything over anything else - my point was that undervolting offers tangible benefits, while bootsplash is simply eye candy.  Regardless, I leave these decisions up to the kernel maintainers, as I lack the knowledge and experience to make informed decisions on such things. -/edit-)
    Now, that aside, as tomk pointed out we're currently having a discussion on what gets included and what doesn't as far as kernel patches go.  Hopefully a solid policy will emerge from this.  However, the attitude of "I didn't get what I wanted so now I'm mad!" won't get you very far.

  • Kernel Patch Update

    Hi
    I have a question about updating the kernel patch to the latest version Can a kernel patch be directly updated from any lower version to the latest version by applying the latest patch even if the kernel patch number itself has changed like the below scenarios
    1. Can I directly update the kernel pacth 122300-51 to 122300-57
    2.Can I directly update the kernel patch 142909-17 to 144488-17
    Thanks in advance

    Basically, yes, but you need to take care of the patch dependencies. Usually a kernel patch with a new patch ID will require the last revision of each former kernel patch to be installed first.
    Either you use patchadd on the most recent kernel patch you want to apply and then work yourself back through the patch dependencies, or you use PCA (http://www.par.univie.ac.at/solaris/pca/) which will do this job for you. Use e.g. "pca -l 144488" to get a list of all the patches which have to be installed first to get the system up to the wanted kernel patch level.

  • Kernel patch problem

    I try kernel patch 114 to 159 but I have a problem
    Distpatcher is being yellow  "Running but Dialog Queue info unavailable" and WP Table is empty in SAP MMC but I can logon SAP on SAP GUI.
    and I can see workprocess in task manager.
    I aleady patch in QAS and DEV . there are not any problems.
    I think MSCS may be cause of problem.
    PRD was confiured MSCS.
    Microsoft cluster library patch was '114' in sapstartsrv.log
    Microsoft cluster library patch must be same disp+work ?
    so how can I get microsoft cluster library patch ?
    and this is not related with problem, how can I do?
    help please
    thanks

    For MSCS there is diffrent procedure to stop SAP for kernel upgrade.
    For windows, open cluster administrator, you will find ur SAP application instance..then righ click on it and select "take offline"
    you SAP MMC may not go show u gray colour, sometimes it will be yellow. then in ur stopped node host, copy ur kernel files. then start server using "bring online" option in cluster administartor.
    do not forget to take backup of ur old kernel before switching the kernel.

  • Static library not accessed properly after Solaris Kernel patch update !

    Hi,
    We are facing a sever issue in our application after our customer updated the Solaris 10 kernel patch u9 to u10.
    We have two static libraries libdlib.a and libDLIB.a, with exactly same code base, but these two libraries are scattered across the code base and linked by many shared objects in our application.
    However, one of the shared objects that links to "libdlib.a" library tries to access a function from "libDLIB.a". This behavior is causing a crash at a later point, since that shared object is supposed to access the function from "libdlib.a". Moreover, we found this is happening through the use of dbx.
    I'm unable to understand why this problem surfaced after kernel patch update, though still the shared object works fine on Solaris 10 u9 patch.
    Flow is something like this :
    1. syslogrecorder.so gets loaded by one of the processes.
    2. syslogrecorder.so is linked to "libdlib.a" at compile time, so it uses "libdlib.a" function DLIB_LoadLibrary and gets a handle to all the function pointers of the loaded library ( The purpose of DLIB_LoadLibrary is to load a shared library dynamically using dlopen )
    3. syslogrecorder.so tries to do a "dlsym" and to do that it needs access to the library handle which we got in previous call DLIB_LoadLibrary. So syslogrecorder.so calls another function from DLIB_ProcAddress, which actually gives back the access to the loaded shared library.
    Here is a catch in step 3, it is supposed to call DLIB_ProcAddress from the libdlib.a but as we observed from dbx output it does so by calling DLIB_ProcAddress from libDLIB.a and hence fails to give back the access to loaded shared library, causing crash at a later point in code.
    Can someone put some light here that why this could happen ??
    Thanks
    Kuldeep

    To clarify: You did not modify or rebuild any of your binaries, but after installing a kernel patch, the application stopped working. Most likely, something about your application depended on a accidental behavior of the runtime loader. That accidental behavior changed due to the patch, and your application failed.
    For example, if there is a circular dependency among shared libraries, the loader will break the cycle at an arbitrary point to establish an initialization order. By accident, that order might work, in the sense of not causing a problem. A change to the loader could cause the cycle to be broken at a different point, and the resulting initialization order could cause a now-uninitialized object to be accessed. I'm not saying this is what is wrong, but this is an example of a dependency on accidental loader behavior.
    Finding your actual problem will require tracing the sequence of operations leading up to the failure. You are more likely to find help in a Solaris linker forum. AFAIK, there are currently no Oracle forums for Solaris, and the old OpenSolaris forums have been converted to mailing lists. You can try the "tools-linking" list found on this page:
    http://mail.opensolaris.org/mailman/listinfo
    I also suggest you review the paper on best practices for using shared libraries written by Darryl Gove and myself:
    http://www.oracle.com/technetwork/articles/servers-storage-admin/linkinglibraries-396782.html
    If you have a service contract with Oracle, you can use your support channel to get more help.

    I think this patch is "bad" as it has been released... but I have as yet seen no acknowledgement of that. Anyone else tried this patch?!
    The machine reboots and runs, but in what state is it left with the new patches running on the old kernel?
    I have posted this to other related groups. Thanks. jj.

    JJ,
    I downloaded and tried to install this patch this weekend. I am having the same problems. Anyone know where I can get patch 108528-21? I need this for a piece of software I am installing.

  • Pchdtv hd-3000 kernel patches

    I just purchased an HD-3000 HDTV card from http://www.pchdtv.com.  Their instructions are for Fedora Core 2.  Since I can't stand Fedora, and I have Arch installed, I was wondering if anyone knew how to install the kernel driver for this card in Arch.  On their downloads page, there are kernel patches, but I've never installed a kernel patch before.  The patches appear to be for kernel 2.6.3 and 2.6.6.  I know that my kernel is 2.6.9.  Would I have to go back some kernels in order to use the patch?  How does one go about using a kernel patch?
    Thanks for any assistance on this topic.

    there's a patch on there.

  • How do I see the Kernel patch level in Java ONLY instance?

    Could someone please tell me How do I see the Kernel patch level in a Java ONLY instance?
    In Abap, it is simple!
    In Java I see in the System Info: Kernel Version:  7.00 PatchLevel 108458.44 
    BUT that doesn't correspond to the real patch level which I can see when I do disp+work which gave me 111

    Hello Yechezkel,
    I am not sure whether the patch number you are looking for is available.
    Typically you can use "-v" to display the patch level of SAP kernel programs. When I run "jcontrol -v" or "jlaunch -v", the patch number is blank (at least on the 6.40 release I checked)
    The SP level should be able to tell how current the Java instance is updated, especially for NetWeaver 7 systems always patched with JSPM stack.
    Best regards,
    Victor

  • Kernel patch 127128-11 renders my x86 system unbootable - what to do?

    Just installed some patches with smpatch as usual, kernel patch 127128-11 among them. I then dropped to single user mode to finish the installation, rebooted and... nothing. I get the SunOS copyright notice, and then nothing but a flashing cursor... I waited for half an hour, but nothing happened, no disk activity, keyboard not responding, nothing.
    I had to reset the stupid machine...
    This happened on old(ish) HP Vectra SFF.
    What I can do now? What are my options? (And please DON'T say: "reinstall everything"!!!)
    I have used Linux for 7-8 years, but Solaris is pretty new for me, this installation is some 2 months old (Sun Solaris 10 - 8/07 - x86)

    I remember I ever tried a tool that you need to run in order to put your computer on the list.
    Well it suddenly crashed and I didn't try it again.The certification tool: http://www.sun.com/bigadmin/hcl/hcts/
    At Sun they know very well which systems I'm running Solaris on.
    This data is sent when you register to apply for updates.They don't use your registration info to list a system as certified to run Solaris10. See link above.
    I have to admit I never added any patches by going into single user mode.I install in single user per instructions in patch README. I have rarely had issues installing patches this way.
    Reading back this thread I see that this patch was part of the Solaris 10 5/08 version
    and since I recently upgraded to this version and everything is working fine,
    I don't think there is an issue. Neither do I think that there is an issue with 127128-11 patch, which is why I mentioned that OPs machine was not on HCL. It's an issue with OPs hardware, not the new kernel. So, what is that 'fix' disabling so that Solaris will run on unsupported hardware?
    I haven't tried OpenSolaris yet. What do you think of it so far?

  • Last kernel patch for Solaris 10 x86 screwed up my kernel

    Hi,
    The last kernel patch for Solaris 10 x86 (sorry I can�t remember the patch id, but the revision is 30), available from Sun Update Manager screwed up my system.
    The system is still booting but in maintenance mode: smf can't start because of repository corrupted. Given instructions to restore the repository does not work because / filesystem is mounted read-only...
    As I am not a solaris expert, I will reinstall it from CD. I hope I won't loose the filesystem.
    I was used to blindly trust Sun solaris patches, that was a mistake.
    Laurent.

    i dont know why but still i do get default log in into the single mode
    after startup
    Requesting maintenance mode
    (See /lib/svc/share/README for aditional information. )
    Root password for system maintenance (control-d to bypass):i did removed the patch installed before so now

  • Solaris 10 U4 and kernel patches

    When I install a fresh U4 machine, I then (as I always do) apply the recommended patch cluster. U4 has kernel patched to 120011-14. In the patch cluster, there are kernel patches 118833-36 and also 120011-14. When I run the patch cluster, it installs 118833-36! Isn't this older than the kernel on there? Shouldn't both 118833-36 and 120011-14 BOTH not install as the kernel is already at level 120011-14. The cluster gets to 118833-36 installs that and then of course every patch after that one fails as the machine is waiting for a reboot.

    KJP 137138-09 should be ok with cpquary3 driver 1.9.1. KJP 137138 introduced new feature which does not allow misaligned pointer mutexes to work and panics the system. with revision 07 SUN introduced a new environment variable as a for applications which cannot be ported easily "6729759 need to accommodate non-8-byte-aligned mutexes".
    This is documented in alert 244606 "The resolution for OpenSolaris releases sets _THREAD_LOCKS_MISALIGNED to 0. This is to ensure that any faulty applications fail and are identified. To allow such applications to continue to work on OpenSolaris releases based upon snv_96 or later, the environment variable _THREAD_LOCKS_MISALIGNED must be set to 1." For this to work you need to have revision 09 of this KJP applied.
    Can you post the stack trace so i can have a look at it. I guess you have another application which uses unaligned mutexes.
    A pkginfo of the cpquary3 package would also be useful.
