Creating initial config when patching a kernel w/ ABS

Hey all, I have a long standing issue with patching kernels that I can't seem to get to the bottom of. My understanding is that coping the config from the stock kernel and patching should provide you with any new options available when the build gets to the menuconfig stage. Do I have to do make config first then rebuild it? Make oldconfig? I can provide more details if need be.
EDIT:
I tried make config and worked through the new options. Then I killed the compilation and copied .config back to the build dir as config. Now the config file shows options correctly. I deleted the src dir and changed the PKGBUILD back to make menuconfig. I ran makepkg but at menuconfig I STILL can't see the options! How is this possible?
Thanks!
Ben

What exactly are you trying to accomplish here?
If i understand correctly you're
1. making your own patchset
2. copying in the config from a stock arch-kernel. (Are you trying to keep it as similar as possible to the stock arch-kernel? If so, why?)
3. toggle some options for the patches you applied and save those to ${startdir}/src/linux-x.yy.zz/.config
4. copy ${startdir}/src/linux-x.yy.zz/.config to ${startdir}/config
5. start a new build, which cats ${startdir}/config to ${startdir}/src/linux-x.yy.zz/.config, and starts make menuconfig
6. wonder why the options you selected in step 3 are still selected in step 5???
I may be missing something here, but i quit smoking 2 days ago...

How to programmatically set initial password when a user is created in OID

We are using the odihragent synchronization process to automatically create users in OID when an employee record is created. We would like to set the initial password for the newly created user to their last name + the last 4 digits of their SSN.
The odihragent process is successfully creating the user in OID and populates the last name and the last 4 digits of the SSN in OID. According to an open SR I have with Oracle, we cannot use the odihragent process to set the initial password because any time the employee record is updated, the synchronization process will reset the password to last name + SSN. They have recommended that we use a pl/sql plug-in to set the password using the WHEN_ADD plug-in procedure.
I am new to using OID and plug-ins and the examples provided in the Developer's Guide are limited.
I would like to know if anyone else is using plug-ins or another process to set initial passwords when a user is created? If you are using plug-ins would you be willing to share a code sample?

I am surprised that I have not received any responses... Surely there are others who are experienced with programmatically setting passwords when new users are programmatically created. Does anyone have any pointers on how to best accomplish this?

Permission problem when trying to patch the kernel

Hello, my name is Rodrigo and I have a VAIO laptop. The problem with it is that it has soo many privative components that are very hard to get to work under Linux. Fortunately, I found a project http://code.google.com/p/vaio-f11-linux/, which aims to provide full suport to VAIOs in Linux.
In order to do this I had to patch the Kernel http://code.google.com/p/vaio-f11-linux … nelSupport
So I started to follow the instructions.
1) I downloaded from kernel.org the lastest stable release (2.6.39)
2) I made cd /usr/src/linux and unpacked the tar contnents from the kernel file into this directory
3) I made "sudo curl http://www.absence.it/vaio-acpi/source/ … 6.39.patch | patch p1" and I got this:
patching file include/linux/sonypi.h
patch: **** Can't rename file /tmp/poSN3DW6 to include/linux/sonypi.h : Permission denied
I don't know if I'm the problem or if the patch is "bad".I already submitted the problem to the Issues page from the project, but maybe I made something wrong, any help would be apreciated
Rodrigo

I don't think sudo was meant for strange things like downloading a patch and then piping it into the patch command. If you want that to work, you should either run "su" to make sure you are root beforehand, or split up the commands like so:
sudo curl http://www.absence.it/vaio-acpi/source/patches/vaio-2.6.39.patch >vaio-2.6.39.patch
sudo patch p1 <vaio-2.6.39.patch
The generic instructions for using this patch will probably work but it will be cleaner if you look at the wiki page for Arch's take on custom kernels.

RAC Linux DB Servers Shutdown When Patching from 11.1.0.6 to 11.1.0.7

Hello.
We have been successfully running a RAC 11.1.0.6.0 64-bit DB on Linux Redhat DB servers. We have had this DB running RHEL version 4 at kernel version 2.6.9-78.0.1.ELsmp. We also had successfully installed the January 2009 family CPU patch. A few months ago we began building a new 64-bit 11.1.0.6.0 RAC cluster set. This new cluster was on a different OS (a patch level up - kernel version is 2.6.9.78.ELsmp (Update 7). To our knowledge, no other OS/HW differences existed between the older, first RAC cluster and the new (2nd) one.
After the SAs handed over the new RAC DB servers to us, we installed the 11.1.0.6.0 clusterware without problem. We then began to install the clusterware 11.1.0.7.0 patch. Here is the problem. When we patch the clusterware up to 11.1.0.7.0, the last thing we are supposed to do is run the root shell script. When we run this script, it starts and never retunrs. In fact, by initiating this script, the node on which it is running actually crashes/shuts down. It does not reboot. It shuts down and we actually have to literlaly go to that server and push the on-off button. We can repeat this on any of the nodes and all of the machines respond the same. We have repeated this cluster build three different times. The first time, the root script finished, but each of the nodes later began shutting down selectively afterwards and we'd have to restart them. On the 2nd and 3rd attempts, the root script would not finish and the node would crash.
Oracle support hinted that we needed to go to the install glibc-2.3.4-2.40 (or above) or upgrade to EL4u7. Well, we are at EL4u7 now and the version of glibc is glibc-2.3.4-2.41. We look fine on that front. They also indicated that we need to install both the 32-bit and 64-bit versions of glibc. When we run "rpm -qa | grep -i glibc", we see:
glibc-2.3.4-2.41:
glibc-devel-2.3.4-2.41
glibc-devel-2.3.4-2.41
glibc-2.3.4-2.41:
We wonder as to why we see TWO (2) entries repeated. Does anyone know why? Also, how can one tell if both the 32 and 64-bit versions of glibc exist on our 64-bit machines? Does the fact that the above duplicate entries imply this?
MOE IMPORTANTLY, has anyone experienced this node/DB server crash when patching up from 11.1.0.6.0 to 11.1.0.7.0? We are out of answers on or end. We cannot even look at the system logs or the ocssd logs because the servers crash immediately upon restarting them.
Thank you.
Matt
Matt

Matt,
When I had this issue and the first node was going in to reboot loop, I remember I saw a message related to 'tick' of some kind. Based on that I thought the cluster is rebooting because of quorum issue with vote disk. So I thought if clusterware don't find vote disk then it will not start and no possibility of quorum issue that was leading to reboot. So I renamed the vote disk and OCR (which was not necessary though) and uninstalled and installed clusterware again.
In /etc/inittab OCCSD daemon is started at run level 3,5 with fatal option. That means if Cluster Synchronization Service (OCSSD daemon) gets terminated it reboot the server. If I had option of starting server to init 1 level, I would open /etc/inittab and comment out following lines and then start server in init 3 level and uninstall clusterware and install again.
h1:35:respawn:/etc/init.d/init.evmd run >/dev/null 2>&1 </dev/null
h2:35:respawn:/etc/init.d/init.cssd fatal >/dev/null 2>&1 </dev/null
h3:35:respawn:/etc/init.d/init.crsd run >/dev/null 2>&1 </dev/null

Wondering if this was the correct way to patch my kernel for CFLAGS?

Hello. I use to build the zen-sources kernel but stopped many months ago. I didn't really need all of those patches but I did miss the Custom CFLAGS/MAKEFLAGS option that the zen kernel had. I also missed the 432HZ Timer frequency setting available in the zen patch.
So I researched a bit and grabbed these parts from the zen patch to add to the Arch kernel:

Well the code was added to my make menuconfig kernel settings, and is in the .config of my newly compiled kernel..... I'm just wondering if I did this correctly. (I'm pretty sure that I did a crappy job of patching since I just grabbed the pieces of the zen patch that I thought were the correct one)..... This is the message from the patch:
patching file Makefile
patching file init/Kconfig
patch unexpectedly ends in middle of line
Hunk #1 succeeded at 734 with fuzz 2.
patching file kernel/Kconfig.hz
patch unexpectedly ends in middle of line
Hunk #4 succeeded at 90 with fuzz 1.
So if someone can tell me a better way to patch the kernel26 for custom CFLAGS and 432HZ Timer frequency (for dual core) I would appreciate it. Thanks.

I'm still trying to find out if I needed to patch any other parts of the kernel source when I added CFLAGS to the kernel modules? I also would like to know if I did the Timing part correctly (so I could use the 432HZ setting for a dual core).
..... so far this kernel has worked ok for the last 4 days. Does anybody know how I can benchmark it and compare it to other kernels that I have built with different settings?
Any info is appreciated.

ORA-01658: unable to create INITIAL extent for segment in tablespace

NEW REPOSITORY INSTALLATION ERROR!!
I want to install a new Repository using Oracle9iR9.2.0.1 and iDS10g on windowsXP Professional the same machine.
After running all the SQL scripts ( ckqa,ckvalqa,ckcreate,ckreport) with success to installing a new Repository on my Database using "the Scripts Method",I start the Repository Administration Utility( RAU) to scheck the priveleges and so on.
After pressing the Install button in the RAU:
-I take public synonyms
-I scheck the box for "Support Designer Objects", then
-The Repository size is Medium
-I have not change the defauft Tablespace of the Repository_Manager names TEMPORARY_TABLES to store the index and table of System Data....Diagram Data.
After Starting, the Installation began an stop by installing some Tables like schown :

I then try to resolve it by schecking and changing the Values of INITIAL_VALUE and NEXT_VALUE in the ckparams.txt to 500k.I change the Values of TEMPORARY_TABLES(10214 to 51200k) and TEMPORARY_INDEXES from (20000 to 100000k).Then I run the scripts @ckparams.txt, @ckvalqa, @ckcreate but
-pressing the Scheck Privileges Button on the RAU still give me 106k for the INITIAL_ and NEXT_VALUE.
-And the installato still stop with the same Error.
Question: How schould I resolve this Configuration?
You could respond in ENGLICH, GERMAN or FRENCH
Thank you for your Help!

You are running into database errors. You should refer to the database documentation on how to adjust the size your tablespaces. The online Designer installation guide will advise you as to the sizes of tablespaces you require.

HT4889 I have accidentally created another account when using Migration Assistant to a new MBA. How do I now 'migrate' all the files from both accounts into one to save myself having two accounts, both of which are me? Help?

I have accidentally created another account when using Migration Assistant to a new MBA. I have read that I probably should not have skipped migration in the initial set up and the problem would have been avoided but, alas, here I am. Does anyone know how I can 'migrate' all the files from one of the accounts that has been created to the other, so then I can delete it and have a single user on the computer seeing as I am the only person using it? I have read starting again, if this is the way to go, where is the best place to start 'starting again'?

Yes definitely should see it but its not coming up (I don't think) when I log out of 2nd user and into the main account. Opening finder in the 2nd account, I can obviously find the public folder because thats where I dropped all the files, but when in the main account, it can't be found. The only public folder that comes up is the folder for that account (main account) and it does not display files I'm looking for. Frustrating....
EDIT: Have found it through a round-about way but all music and photo and movie etc files have a red stop sign disallowing them from being transferred. Can you guess what the next question will be?

[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.

Logic of G/L account while creating initial stock.

Dear all,
When creating initial stock-trcode MB1C movement type 561- SAP requests a G/L account. I think in other material movement types, SAP requests a G/L account same as here. What is the logic here? Why SAP request G/L accounts for these processes?
Thanks in advance.

Hi,
Initial stock upload transaction MB1C does not normally require a G/L account, if MM inventory posting related customization is complete. Because inventory posting calls for auomatic account determination.
Please check whether MM inventory posing related customization (Transaction codes:OMWN & OBYC) is complete. Specifically, please check in OMWN, whether account assignment has been made for movement type 561.
If the issue is resolved please acknowledge the same.

Lightroom opens fine initially, but when trying to open a different catalog it will go through the process but never reopen again. I can't get it to open at all until the computer is reset. I have been using Lightroom 4 for 18 months now and this problem just started happening in the last month.

No error messages. It acts totally normal but just never reopens when I try to reopen a new catalog. I create a catalog for each of my clients....I have done this since I started using lightroom as it seems tidy to me. But, I have never had this problem until now. I am using a pc and vista and Lightroom 4. Thanks.

Import fails (cannot create initial extent)

I am running an import (using the interactive screen, and importing 1 user only)
After creating a couple of tables, the import starts failing with "cannot create initial extent" errors.
When I look at the free space, the tablespace I am importing into, has no free space left.
What I don't understand, is that - I created this tablespace exactly the same size, as the tablespace I exported from (on a remote system). Source=4Gb, Target=4Gb
Why is this happening ?

I was never faced with that issue before so I am just guessing...
Did you create the tablespace with the same initial/next extent values?
Also, have you tried setting the tablespace to autoextend? It will not answer the "why", but it will at least allow you to see how much larger that tablespace needs to be and let the import finish.

Need help patching a kernel to use new ALSA

I have a friend who's just starting out with Arch, and I've been getting him started on his install. His system uses a Biostar 6100-939 motherboard and an Athlon64 processor.
Everything has been working so far except sound. According to documentation, the correct ALSA driver for his nForce4 chipset should be the snd_intel8x0 module. However, loading this module didn't make any soundcards available to alsamixer.
We started to investigate the problem, and recently found this: http://jrbelvin.freeshell.org/weblog/linux/mcp51-alsa stating that the problem is fixed with the 1.0.11rc3 release of ALSA. We also found this : http://www.nvnews.net/vbulletin/showthread.php?t=60493 covering the same issue. We tried applying the patch listed in that forum to a build of the ArchCK kernel. While we were able to confirm that our patch really did patch the kernel, and that the patched kernel built, the snd_intel8x0 module still didn't work when we loaded our patched kernel.
So now it seems like we'll have to properly use the 1.0.11rc3 release of ALSA to get sound working on his computer until 1.0.11 is finalized and merged into the kernel. Does anyone have any experience on patching a kernel to use a different release of ALSA? Any help would be appreciated.
Woogie

I had the same problem with my new computer (less than a week old) using an ASRock K8NF4G-SATA2 board. For me the problem stopped when I switched to the 2.6.16 kernel then in testing but now in current. If it's not working with that kernel try modprobing snd-intel8x0 by hand and running alsaconf.
I actually made packages of alsa-lib and alsa-driver 1.0.11rc4 for myself in the process, but I've switched away from those again, so I don't think they should be needed for NF4/MCP51 to work. That said if your problem doesn't go away I'll be happy to post the PKGBUILDs I modified or even send the packages themselves (with absolutely no guarantees).

"Create new versions when making adjustments" - Lion, Aperture 3.1.3

I recently upgraded to Lion, and then shortly thereafter to Aperture 3.1.3.
While I don't seem to share everybody else's issues with Lion nor with Aperture, I do have one of my own.
In Preferences -> Advanced, I have a box titled "Create new versiont when making adjustment." It is checked.
My expectation, (and the way things have always worked under Snow Leopard) is that if I select a master image and begin to make adjustments to it from _any_ feature int he adjustments pallette, that I new version will be created, stacked next to the original, and that the changes I am making will be made to the new version. This is _not_ what is happening.
Instead, the changes are applied directly to the master image. This is annoying, and will probably be fixed in an update...    I thought the work around would be to manually create the version for the time being, until Apple sorts this out. That didn't work either.
If I manually create a version, and then proceed to make adjustments to the version, Aperture dows what I would have expected in the first place. It creates a new version and applies the changes to that.
For example, I right click on a master image and select "New Version form Master" A new version, titled "... - Version 2" is created. When I begin to modify Version 2, a new version is created titled "... - Version 3" and my changes are applied to this version... leaving me with the master and Version 2 which are now duplicates of each other.
Even more interesting is this:
Images that were imported into Aperture prior to the Lion upgrade, and the 3.1.3 patch behave as expected, in that a new version is created when adjustments are applied to a master image.
Images that were imported into Aperture _after_ the upgrade to Lion and the 3.1.3 patch act as describd above, in that no new version is created when adjustments are applied to a master image.
So... Here are the questions:
1. Is anybody else experiencing this?
2. Does anybody know how to restore the correct behavior?

Alright,   I have solved the problem.
Some time ago, I thought it might be neat to import pictures with the Auto Exposure adjustment in place. What I didn't realize was that if the master image is in the library with adjustments on it, it downs't create a new version when you add additional adjustments.
As soon as I disabled that, and imported some new imges the probelm went away.
Also... I went back to the six or seven project that I had imported while use Auto Exposure and removed that adjustment from those images...
All is resolved.

[SOLVED] How do I patch the kernel?

EDIT (again): Doesn't seem like the patch is needed anymore. 3.3.1 kernel from the repos seems identical to my custom kernel (also 3.3.1).
EDIT: The patches are for an older kernel but I was able to apply them manually.
Hello. I'm trying to patch the kernel using the patch found on this page: http://lists.freedesktop.org/archives/i … 09584.html
Now, I don't know much about patching but the patch in that post looks more like the program output of several diff commands. How do I format this to create a valid .patch file?

To get back to my original question, making a patch out of what was in that mailing list post:
