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

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
Presto! you have finished upgrading.

first Find which stack your system is running. this is source stack. then find give the target (say SP14) in service market place. this will give all necessary stacks from your source to target. download them.
hope i managed to throw some light!

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

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.

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.
Tim

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.

Patch levels for Oracle and kernel

Hi everyone,
Can you pls tell what are the maximum and minimum patch levels that can be used for BW 3.5 installation on LINUX RHEL 4 ,
oracle -10.2.0.2 & kernel - 6.4 .
Thanks in advance,
Praveen

hi people,
we have checked for the status of support package in Transaction SPAM traffic signal is still red and in the Phase RUN_SPAU_? it is stuck and even after restarting import it shows clean-up phase is left and it ends with same error mention above
the support package name is SAPKB70014 size is 116266 MB now after restarting the Import the following error message comes
The import was stopped, since an error occurred during the phase RUN_SPAU_?,
which the Support Package Manager is unable to resolve without your input.
After you have corrected the cause of the error, continue with the
import by choosing Support Package -> Import queue from the initial
screen of the Support Package Manager.
The following details help you to analyze the problem:
- Error in phase: RUN_SPAU_?
- Reason for error: TP_CANNOT_CONNECT_SYSTEM
- Return code: 0255
- Error message: Could not connect to semaphore server
we run all the phase in background, and even after entering the support package number in transaction SPAU there it is showing
"No objects within selected filter parameteres"
Q.1 Any idea what went wrong and how to fix that?
Q.2 Is there any problem if we run the all four phases of support package in background or it should be run in dialog
latest tp & R3trans updated?

TP_STEP_FAILURE " ERROR WHILE APPLYING SAP NW 04 SR1 ABA AND BASIS PATCHES

Hi Freinds!!
..I have completed cinst, dbinst, client copy, jinst, xinst installation for XI 3.0 INSTALLAION ON ABAP + JAVA.
I have first applied PI_BASIS patches and middle of it, it displayed the message that pre-requisite are not met i.e. First SAP_BW , SAP_BASIS, SAP_ABAP pathces needs to apply.
While applying SAP_BASIS and SAP_ABA patches... I'm getting the following error message ...

....So, what could be the cause of the problem ? Do I need to increase table space through brtools command at ora<sid> ?!!
Pl. help....
Many thanks in advance...
-Rupen Patel

Thanks a lot everybody.
Although I had upgraded Kernel Patch Level from 43 to 155, the real cause was, it seems that was maxed out Oracle Table, ..as I found it through ST22 tr code which inturn displayed a logfile which displayed the details of error. I used brtools to extend the tablespace of a table, reapplied the patches thorugh SPAM and it worked out quite smoothly.
Thanks again and Regards,

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

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.

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 108528-26 bad?

On machine: SunOS boedev 5.8 Generic_108528-14 sun4u sparc SUNW,UltraAX-MP
As part of the J2SE recommended patches, I attempted install of the downloaded 108528-26 kernel patch and received:
<snip>

This appears to be an attempt to install the same architecture and

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.
Thanks,

Kernel patch level

hello,
We have 3 system landscape DEV, QAS & PRD on HP-UX, oracle 9.2, ECC 5.0.
kerne patch level of DEV system is 196 and QAS system is 347 and PRD system's kernel patch level is 196
can this is affect on request transporting DEV to QAS and PRD or any issues plz. guide me
thanks

Hi,
No problems for tranports but you're not qualifying what will be running on production....
The whole point of a quality system is to use exactly the same release, kernel patch levels and SP levels as the prodcution system.

Olivier

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.

http://www.thegeorges.us/mythtv/
there's a patch on there.

Audio and Kernel settings

OK - I've spent all afternoon searching and reading and, either I'm stupid, or the answer isn't obviously out there.
Since I reckon it's probably the former - try and speak slowly for me
I want to use my desktop primarily as an audio workstation - by which I mean I want to run things like ardour and do audio recording/editing etc.
I've got most of the tweaks to my system done - but I'm really not sure what, if any, changes I need to make to my kernel. I'm currentlyu running the stock kernel and things generally seem fine - but I'm not sure if I could improve things.
The linux-musicians website suggests the following changes to the kernel config:
CONFIG_HZ_1000=y
CONFIG_HZ=1000
CONFIG_PREEMPT_RT=y
CONFIG_PREEMPT=y
Is this still necessary with recent kernels?
Any advice/suggestions welcome.

CONFIG_PREEMPT_RT is for the real-time kernel only. If you're doing serious DAW stuff, then you'd probably want (note, not NEED I think) that. Unfortunately, the kernel I use to get rt (kernel26-ice) has just upped to 2.6.30 yesterday and as a result the rt-patch doesn't work, till they come out with a 2.6.30 one.
Best to wait for the proper rt-kernel patch to come out, then use the kernel26-ice PKGBUILD to compile it with the above options. I have the kernel compiled here from a month back, but not sure if there's anyway to send it to you.

Applied Kernel Patch to Solaris 10 on v40z, no longer auto boots

I recently updated the patches on a v40z machine including a kernel patch. After rebooting, the machine would no longer automatically boot to Solaris. Instead it would just wait for user input at the Grub bootloader screen. Anyone experienced this or have a solution?
I believe the patch in question is 118855-19
# bootadm list-menu
The location for the active GRUB menu is: /boot/grub/menu.lst
default 0
timeout 10
0 Solaris 10 6/06 s10x_u2wos_09a X86
1 Solaris failsafe

SOLVED:
Disabled ECC in the bios (though Windows and Gentoo Linux show now trouble whatsoever with my ECC memory, solaris doesn't like it)
