Kernel Patch Upgrade

Hi all,
We have our production system which is on ECC 6.0 with Oracle 10.2.0.2.The CI is on HP-Ux and there are 3 Application servers on Linux. All are on kernel patch level 95 and we need to update the kernel patch level to 124 in all the CI+apps
I just wanna know if the scenario below is correct
1)stopsap on all the apps
2)stopsap on the CI
3)Do the kernel upgrade on CI
4)Start sap on CI,chec if its fine
5)Then update kernel in individual apps and start sap on the apps server.
I guess its right..But just wanted to know if this is the best possible thing or something else is better than the above scenario.
Regards
Bharathwaj V

Hi Bharathwaj V,
your scenario sounds good.
Just some remarks:
- after stopping the app server / CI, also stop saposcol before changing the kernel
- make sure to run the same patchlevel on all appservers and CI (you seem to know about this already)
- run "saproot.sh <SID>" as root after changing the kernel before restarting the CI and appservers. saproot.sh is contained in the exe-directory, it will set the exe-settings of saposcol and br*
- because of the special settings of saposcol and br*, you'll have to change the kernel files as root
- keep a backup of the old kernel (copy exe to exe_PL95) until you are sure everything works fine.
Best regards,
Elmar.

Kernel Patch upgrade results into error

Recently, we upgraded our R/3 640 kernel from patch number 196 to 327. It went successful.
But now, the Sales and order team is having problem in saving the orders(VA02, VA01).
While saving Sales order, error pops up saying "dialog step number missing".
Kindly suggest.

Hi ppl,
The problem has been resolved.
As i said, problem wasnt with the upgrade, but came thereafter, functional team faced issues while switching between the windows.
Problem was with the Gui level, it needed to be upgraded too after the kernel patch upgrade.
Thanks a lot for putting your thoughts.
Thanks

Backup error after kernel patch upgrade

Hi.
I have a backup problem after the kernel patch upgrade. I have SAP R3 4.6C on HPUX11.0 with an Oracle 8.17 database.
I have upgraded kernel patch from 1655 to 2337.
Afterward, I am getting following backup error:
BR280I Time stamp 2007-11-06 09.29.01
BR279E Return code from '/usr/sap/HAD/SYS/exe/run/backint -u HAD -f backup -i /oracle/HAD/sapbackup/.bdwnpztp.lst -t file_online -c': 2
BR232E 0 of 115 files saved by backup utility
BR280I Time stamp 2007-11-06 09.29.01
BR231E Backup utility call failed
Does anyone know how to correct this?
Thank you.

Hi Jun,
backint is a link file that is in SAP kernel directory which links to the backup client on the server.
eg:
lrwxrwxrwx 1 root other 32 Aug 13 2004 backint -> /usr/openv/netbackup/bin/backint
As part of kernel upgrade process, the kernel is backed up, mostly on the disk before upgrading. Check if this link exists and recreate it in the kernel directory, if no backup was done, compare it with other systems to get the details of the backint link.

Nisch

Solaris 10 kernel patch upgrade

Hi all,
i am in a process of upgrading the kernel patch of a solaris 10 x64 machine, the present kernel patch is "5.10 Generic_144489-06 i86pc i386 i86pc" the updated kernel patch that i am going to upgrade to is patch "144501-19".
could you please let me know if there is any special handling to undergo the upgrade or it is only sufficient to follow the 144501-19 README file?
i know that i should put the system on the single user mode level and i have to have a valid OS backup before doing the patchadd, but if i am missing anything else please let me know
thanks

Hello,
if you are having system filesystems (/ /usr /var ...) on software RAID1 devices, best practise is to split mirrors and have most recent actual copy of the system (or create current ZFS snapshot if using ZFS on root),patch it in single user mode or use Live Upgrade functionality and create alternate boot environment and patch the ABE on running system (you can find various info in Oracle Docs or get inspired by various blogs:http://nilesh-joshi.blogspot.com/2011/10/oracle-solaris-patching-using-live.html). I always patch kernel and other system components using PCA patching utility - have a look on project homepage http://www.par.univie.ac.at/solaris/pca/ it's really advanced and helpful tool. It can save you lot of time when solving dependecies and also downloading the patches.
Good luck

Kernel patch upgrade for multiple instance

Hi expert,
I want to know will we follow the same process while upgrade the kernel patch only for Multiple ABAP STAK.
We have system which has 3 instances....................so my question is exactly where we ned to put the kernel files (Generlly it should be in /EXE or /RUN file)and in which instance.......

1.If I copy the patches only in central instance will it affect to all other instances.....?
If you have configured your SAP system correctly then Yes, Kernel upgrade in Central Instance will reflect in Dialog Instances also.
2.what is the concept of SAPMNT..(/sapmnt/SID/exe ).........?
/sapmsnt/SID/SYS/exe -> to share the kernel across the instances
3.What is the difference between EXE and RUN directory ............will it make any difference if I copy into EXE folder instead of
/usr/sap/<SID>/SYS/exe/run is located on the host system of the R/3 instance and is for locally-stored executables
/sapmsnt/SID/SYS/exe/run -> Central Instance directory
/usr/sap/<SID>/SYS/exe - Dialog Instance directory
you can check the values of DIR_EXECUTABLE or DIR_CT_RUN (if you are using sapcpe) to determine the kernel directories for central and dialog instances respectively

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

Kernel patch level upgrade

our kernel patch level is 221
now i want upgrade patch latest non unicode 64bit kernel for DB2 database
E:\usr\sap\QAS\SYS\exe\nuc\NTAMD64
E:\usr\sap\QAS\DVEBMGS00\exe
which one correct directory..

Dear Subhash.Chandra.
You writed the patch files have to be copied both directories.
I'm finding the official document or manual of it.
I updated igs patch on one server(ecc 6.0 ides).
I copied the file to one directory(/sapmnt/SID/exe). and I found igs patch was OK(transaction : sisg).
And the the other directory(/usr/sap/SID/DV~~/exe) has same file automatically without copy.
Second Case,
I updated igs patch on our ecc dev server.
I can't update igs version with copy to only one directory.
So I copied remained directory. Then I found igs patch updated successfully.
Thank you.

System Core Dumped after Oracle patch upgrade 9.2.0.6 to 9.2.0.8

Hi,
We are continously getting dumps on our BW Central instance server after we did an Oracle patch upgrade from 9.2.0.6 to 9.2.0.8.
Following is our system environment
SAP Release.............. "640"
Application server....... "abci"
Operating system......... "SunOS"
Release.................. "5.10"
Hardware type............ "sun4v"
Database server.......... "abdb"
Database type............ "ORACLE"
Database name............ "ABP"
Database owner........... "SAPABP"
SAP kernel............... "640"
Database version......... "OCI_920 "
Patch level.............. "175"
Following below is the Core Dump that is generated for any process chains that we schedule on our BW server
Runtime Errors         SYSTEM_CORE_DUMPED
Date and Time          14.04.2008 09:26:17
ShrtText
     Process terminated by signal 11.
What happened?
    The current ABAP program had to be terminated because the
    ABAP processor detected an internal system error.
    The current ABAP program "SAPMSSY2" had to be terminated because the ABAP
    processor discovered an invalid system state.
What can you do?
    Make a note of the actions and input which caused the error.
    To resolve the problem, contact your SAP system administrator.
    You can use transaction ST22 (ABAP Dump Analysis) to view and administer
    termination messages, especially those beyond their normal deletion
    date.
Error analysis
    An SAP System process was terminated by an operating system signal.
    Possible reasons for this are:
    1. Internal SAP System error.
    2. Process was terminated externally (by the system administrator).
               Last error logged in SAP kernel

How to correct the error
    The SAP System work directory (e.g. /usr/sap/c11/D00/work ) often
    contains a file called 'core'.
    Save this file under another name.
    If you cannot solve the problem yourself and you wish to send
    an error message to SAP, include the following documents:
    1. A printout of the problem description (short dump)
       To obtain this, select in the current display "System->List->
       Save->Local File (unconverted)".
    2. A suitable printout of the system log
       To obtain this, call the system log through transaction SM21.
       Limit the time interval to 10 minutes before and 5 minutes
       after the short dump. In the display, then select the function
       "System->List->Save->Local File (unconverted)".
    3. If the programs are your own programs or modified SAP programs,
       supply the source code.
       To do this, select the Editor function "Further Utilities->
       Upload/Download->Download".
    4. Details regarding the conditions under which the error occurred
       or which actions and input led to the error.
Kindly help.
Regards
Sachin
Edited by: Sachin N on Apr 14, 2008 12:26 PM

No. If the environment would be wrong the system wouldn´t start up.
Core dumps are in 99 % of the cases program errors (in the SAP kernel or in an interface (libdbora*)), misaligend accesses of data etc.
If you encounter such an error have a look in the C-Stack. If you can´t see where the error is happening opening an OSS call. Most of those errors are fixed by installing the latest patches for the kernel and the database interface.

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.

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?

Kernel patch update for solaris 10 x86

I have Solaris 10 06/06 installed on x86 machine which is using svm and clustered with another node. The kernel revision is 118855-19 from the uname -a output. I am looking for the kernel patch updation and I heard 118855-36 is the latest one. Shall I go ahead with this patch and what r the dependency patches for this.
If anyone done this please suggest and guide me..

For Solaris 10 x86 the latest offered with smpatch is 125101-07 and yes it may be recommended to patch. Then again you said clustered with sun cluster? You may want to check the documentation and if your machines aren't facing the internet you may wait for 7/07 to hit the street and do an upgrade.

Solaris 10 kernel Patch 127127-11

we need to apply solaris 10 kernel Patch 127127-11 in our prod server as a prerequisite for oracle10g patch set 10.2.0.4 installation
but i found a Doc 242366 (May Cause a system Panic from ip_wput_ioctl()).It is mentioned in doc that Binary relief is available through normal
support channels.Is that Binary complete fix of this problem?If yes, then i need that binary please give me the link where i can download the binary,
If not, then what is the solution of this problem.?
Thanks

These kinds of binary hotfixes/IDR's are only available through sun support to contract customers.
If your concerned, I suggest you raise a support case.
That being said, 127127-11 is kinda old. So I would be surprised if the bug hadnt been fixed by now.
Its been replaced by either 137111 or 137137.
Ive upgraded at least a dozen systems past that level and never seen a problem.
So it can't be too common..

SP 's and Kernel patches

Hi all,
I have a few questions and want clear my basics.
Is Kernel upgrade the same as applying a kernel patch? For any SAP system release, there's
just one kernel version right? We just keep applying new patch versions to update it. Is this
correct? Please throw some light.
secondly, in SPAM, what is the difference between new and imported packages? When trying
to apply latest support packages, what steps should you follow? And what are support package
stacks? I know they are a collection od packages but how to find out which one I will need
depending on the current package status of my system?
Thanks in advance
Cyrus

hi Cyrus,
> secondly, in SPAM, what is the difference between new

> you follow?
SPAM - Support Package Manager is used to put ABAP patches in your system. Imported packages mean the packages that are already imported in your system. say your WAS is on SP9 - this means you will find SP1..SP9 in imported packages. this will be useful if you are patching it up in stages. you will find which are already imported and hence put the rest. Sometimes higher patches needs to have some prerequisites. you may find if these prerequisites are satisfied.
New packages are already loaded but yet to be imported. You will find the traffic light - Yellow. for imported packs you will find it green.
if you want to apply latest support packs, first load them into your ABAP system after downloading them from service market place. you may do it using the SUPPORT PACKAGE --> Load FROM FORNT END. then upload the car files and Display/Define Queue. then Import Queue. after queue is imported, Confirm
