Oracle8051 on linux Kernel 2.2.13

error in the execution of svrmgrl, message: segmentation fault

i've got rh6.0, glibc 2.1, kernel 2.2.13
running ok with 8.0.5.1 EE.
8.0.5.1EE is a glibc 2.0 product and the
binaries between 2.0 and 2.1 are not compatible.
You will want to ensure you have the correct
set of libraries installed.
Did svrmgrl work prior to a kernel upgrade?
If so, you will want to check your ipc
parameters & tcp parameters when you built
the new kernel.
hope it helps!
nice to see oracle's reponse to the issue.

Linux: Kernel Preemption, To Enable Or Not To Enable

The default 2.6.4 Arch Linux kernel .config has 'CONFIG_PREEMPT=y'.
Not everyone has been happy with kernel preemption, however. There is an interesting discussion of this under the title "Linux: Kernel Preemption, To Enable Or Not To Enable at http://kerneltrap.org/node/view/2702
The text of the article is repeated here:
"A recent bug report on the lkml complained of significant performance degradation from enabling CONFIG_PREEMPT, kernel preemption. 2.6 kernel maintainer Andrew Morton [interview] pointed out that such degradation from enabling kernel preemption is not normal, instead likely from it triggering a bug. However, an interesting conversation on the merits of kernel preemption followed.
Andrea Arcangeli, author of the 2.4 virtual memory subsystem, bluntly suggested, "keep preempt turned off always, it's useless. Preempt just wastes cpu with tons of branches in fast paths that should take one cycle instead." Andrew Morton noted, "preempt is overrated." However, he went on to point out that kernel preemption has been very useful in detecting locking bugs. He added, "it has been demonstrated that preempt improves the average latency. But not worst-case, because those paths tend to be under spinlock."
Robert Love [interview] replied directly to Andrea's comments saying, "I think you are really blowing the overhead of kernel preemption out of proportion," going on to agree with Andrew's statements. He further explained:
"I also feel you underestimate the improvements kernel preemption gives. Yes, the absolute worst case latency probably remains because it tends to occur under lock (although, it is now easier to pinpoint that latency and work some magic on the locks). But the variance of the latency goes way down, too. We smooth out the curve. And these are differences that matter."
There is more discussion and feedback with the article (including the original bug report).

I like preemption. it the "democracy" heaven of processes and threads. This post was interesting, but the point is this bug..?
if the bug is found, who can say that preemption in the kernel is not a good idea?
thanks for posting though ;P

We had the same problem with the PL/SQL cartridge (OWS-04764 ...). We solved our problem with a new kernel. Its important that you have a kernel with symmetric multi-processing support (SMP) enabled, independent if you have a one or two processor machine.
I hope it will help you.

[SOLVED] Intel i7-3920XM Laptop CPU Linux Kernel Support

Recently, I purchased a laptop with an Intel i7-3920XM CPU, with the intention of utilizing it for scientific computing (I've become strongly interested in machine learning and artificial neural networks). Supposedly, the CPU has a variable clock speed of 2.90 -- 3.80 GHz, which would be great, but my kernel has throttled it to 1200MHz. I've tried both the cpufreq performance and userspace kernel modules (configured for performance), but the laptop stubbornly refuses to increase the clockspeed more than 1200MHz; I gave up on cpufreq and have uninstalled it. I've read some accounts that it is possible that the Linux kernel may not support my CPU yet --- does anybody know if that is the case? If it is not, can anybody point me to some literature describing how to un-throttle my CPU?

You should just leave things as they are, if you can actually feel sluggish performance ( I don't with 6 cores @ 1200MHz) you can try this:- https://wiki.archlinux.org/index.php/Cp … erformance
Which will liven things up a bit at the cost of more battery juice.
EDIT/ compile something and whilst compiling
cat /proc/cpuinfo | grep MHz
to see what's reported at full load, but be aware it still may not report correctly due to turbo.

I would agree with you if that was what the argument was about. I said the same thing about i7z as you just did, which is why i suggested it. as I understand it. your telling him 1.2 Ghz is an acceptable min and i would agree.How i am interperting his thread is 2.90 Ghz is his base. 3.80 Ghz is his max turbo. His CPU under 100 % load will not rise above 1.2 Ghz despite his stock clock is actually 2.90 Ghz. I can honestly say that this is the more likely story because my i7 did the same thing. on battery the max it would clock up to while runing /dev/urandom > /dev/null was 1.2 Ghz, while on Ac it would even turbo correctly. by unloading the module. my proccessor would clock as expected 800 mhz min 3.4 max turbo. and if you look he even used the performance governor to try to increase the clock
Ya, really the OP did not tell us 'how' he was reading his CPU speed....

runny6play: If deltaecho is also seeing these same slow speeds in i7z then both you and he should look into your BIOS settings. For sure this would be a BIOS setting on a ThinkPad. "If on battery....slow... if on AC...fast".
Yes, it is the Linux Kernel that is no "Reporting" the correct speed. This is a known bug. However, there is nothing wrong with your CPU. It is running at High Speed.. Like this is the read out from my Kernel at idle...
[user@archtop:~]% sudo cat /proc/cpuinfo | grep MHz
[sudo] password for user:
cpu MHz : 1200.000
cpu MHz : 1200.000
cpu MHz : 2901.000
cpu MHz : 1200.000
The BEST way to test your CPU is, again i7z then compile some code... Like change the MAKEFLAGS="-j4" to -j1 for 1 thread, -j2 for 2 threads.... and so on. Compiling software will push your CPU all the way up.
When testing like this, i7z will show on 1 thread my CPU runs at 3.6GHz, on all 4 threads it runs at 3.4GHz, as it should. However, /proc/cpuinfo will only say wacky stuff like cpu MHz: 1200.000 cpu MHz: 2901.000

Nikal linux kernel 2.6.11.8 build fails

I am trying to install nidaqmxbase-1.5.0-f2, but the install keeps failing. I tried installing with a stock FC3 kernel, but the build has failed. I have since tried again after building a stock linux 2.6.11.8 kernel, but I get the same error message. The "warning: `packed' attribute ignored" in particular is one I haven't seen before.

I found the answer to my question in another thread:
http://forums.ni.com/ni/board/message?board.id=250&message.id=11286&requireLogin=False
It appears that NI-KAL doesn't like the 2.6.10+ linux kernel due to a change in the API. Both the kernels I tried were 2.6.10 plus.
Perhaps in the next release if nidaqmxbase the latest kernel will be supported? Hint, hint, pretty-please from a paying customer. ;-)

Is RDAC supported in Oracle Unbreakable Linux kernel 2.6.32-100.0.19.el5?

Dear,
Is RDAC supported in Oracle Unbreakable Linux Kernel 2.6.32-100.0.19.el5?
If supported, please point to the download link.
We require this in order to plan for the OEL 5.5 kernel upgrade to ULK and to connect SUN SAN storage array 6180.
Thanks,
...basha

From what I can gather you will need to compile the driver from source in order to use the RDAC driver with the UEK kernel. Chances are that it won't compile properly under the UEK kernel, which is more up to date than the RHEL kernel.
You will have to start the system from the supplied original RHEL kernel in order to use the binary IBM RDAC driver distribution. The following is available: http://www.lsi.com/sep/Pages/rdac/ds4000.aspx and http://www.lsi.com/sep/Pages/rdac/ds3000.aspx
You may however be able to use Multipath, which is build in also in the UEK kernel. To get the current supported configurations for IBM System Storage it is best to use the interoperability matrices located at http://www-03.ibm.com/systems/storage/product/interop.html. You can use the link to the "System Storage Interoperation Center (SSIC)" to query your specific configuration (http://www-03.ibm.com/systems/support/storage/ssic/interoperability.wss)

Listing of All Linux Kernel Modules

I've been poking around, trying to find a list of all available Linux kernel Modules.. Does anyone know where such a list may be located?
Basically looking for something that gives the module name (like - nvidia) and then a quick explanation or description of it (like - nVidia Video Card Module).
If I find something, I'll stick it on the wiki; but thought someone may have already run across it somewhere.
thanks!!

This will provide a list of modules
modprobe -c | less
An example output portion will look like this:
alias pci:v00001133d0000E00Bsv*sd*bc*sc*i* hisax
alias pci:v00001133d0000E005sv*sd*bc*sc*i* hisax

alias pci:v00001244d00000A00sv*sd*bc*sc*i* hisax
alias pcmcia:m*c*f*fn*pfn*paD79E0B84pb21D083AEpc*pd* sedlbauer_cs

alias pcmcia:m*c*f*fn*pfn*pa81FB79F5pbE4E9BC12pc8DB143FEpd* sedlbauer_cs
To get information on what each module does
yum -y install kernel-doc --This will install the kernel documentation to /usr/share/doc/kernel-doc-*/Documentation (* is the version of the kernel you are using)
If we wanted to get info on the 'hisax' module
cd /usr/share/doc/kernel-doc-*/Documentation
grep -R -i hisax * --This will list any docs on the module, in this case will find that it is a driver for a Siemens ISDN card

MHDDK broken on Linux kernel 4.0

One of the tools that ships with MHDDK is broken on new Linux kernels.
The problem is easy to reproduce:
cd nimhddk_linuxkernel/LinuxKernel/nirlpk
make
sudo make install
gives the following error:
nirlp: 4.0.0-040000-generic kernel not supported
Directly executing nirlp gives the same error. Older kernels (e.g. 3.13) don't have this issue.
Without this tool, none of the examples can even access the board.
This issue will presumably affect all new kernels. Since this tool is binary-only, a fix will have to come from NI.
NI, please provide a fix or workaround for this issue.
Solved!
Go to Solution.

drobson wrote:
Since this tool is binary-only, a fix will have to come from NI.
The MHDDK is 100% source code, scripts, and Makefiles -- all editable text files.
The nirlp file is a bash script, and it includes a check for kernel versions that were tested with the DDK examples. The last time the kernel module was updated was during the Linux 3.6 window. You can change the script to allow for newer kernels, and since you were able to compile the module, it looks hopeful that the module will load and support your devices.

CentOS based linux VM running on Hyper-v : Checking root filesystem fails when kernel switches having old PV(para virtualised driver based on 2.6.32 linux kernel) to new PV(which is equivalent to linux integration component 3.4)

hi all,
I am running a CentOS base VM on top of Hyper-V server. I upgraded PV drivers of Hyper-V in linux kernel 2.6.32 in order to support
Windows Server 2012, then i am hitting below issue on Windows Server 2008 when kernel switches from old PV(which is 2.6.32 based) to new PV(which is equivalent to linux integration component 3.4).i
am hitting following filesystem check error messages :
Setting hostname hostname:
Checking root filesystem
fsck.ext3/dev/hda2:
The superblock could not be read or does not describe correct ext2 filesystem. If the device is valid and it really contains an ext2
filesystem(and not swap or ufs or something else),then the superblock is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
: No such file or directory while trying to open /dev/hda2
*** An error occurred during the filesystem check.
*** Dropping you to a shell; the system will reboot
*** When you leave the shell.
Also, when I go to the repair filesystem mode. I found out the strange behaviour when i ran those command :
(Repair filesytem) 1 # mount
/dev/hda2 on / type ext3 (rw)
proc on /proc type proc (rw)
(Repair filesystem) 1# cat /etc/mtab
/dev/hda2 /ext3 rw 0 0
proc /proc proc rw 0 0
(Repair filesystem) 1# df
Filesystem 1K-blocks used Available Use% Mountedon
/dev/hda2 4%
I think for all above command there should be /dev/sda2 instead of /dev/hda2.
Also my fstab , and fdisk -l looks like ok for me.

Error: Unable to find sources for current Linux Kernel

Hi Guys,
Hit a bump !!!!
Oracle Linux x86-64 installed successfully via Oracle VM box.
Clicked on 'Install Guest Additions'.
Ran VboxLinuxAdditions.run to install the Guest machine on Linux. It Failed and in error log (/var/log/vboxinstall.log) got the below error:-
Error: Unable to find sources for current Linux Kernel. Specify KERN_DIR=<directory> and run again
Looking upto Google i found I need to update Linux headers , in doing so get +'bash: apt-get : command not found'+ which I am not able to understand.
Any assistance is appreciated.
Cheers

Thanks for the information. I was able to resolve it though.
Ran +'yum install gcc kernel-devel kernel-headers'+
Hence my query is resolved now.
Just one question - I need to copy text from Windows to Linux Terminal. Is there a command I can type into Linux terminal to enable copy paste from Windows to Linux and vice-versa ?
Cheers.

X120e - ACPI - Dual Boot - Linux Kernel Stall

Hello everyone!
I'm running in a really weird issue. Each time I reboot from Win 7 to Linux (after selecting linux on the grub menu), the Linux kernel will stall, showing some ACPI related message. Is there any way to sort this out? Cause it's really a pain to hard reboot each time.
Thanks!!
http://oi45.tinypic.com/fpaux2.jpg

Try giving Acpi=off during boot time in the kernel parameter,that might help?
Cheers and regards,

Tuxedo 8.1 running on encrypted linux kernel

Hi,
Is anyone try to run Tuxedo 8.1 on Redhat linux kernel version 2.4.22 or above with encryption?
Thanks.
Thomas Gan

I've had success with the RedHat AS3.0 (Pentium) version running on SuSe Linux 9.1 both 32bit and x86_64 builds

OEM12c agents high CPU usage alerts fix (leap second Linux kernel bug)

Just throwing this out here in case anyone else spent the weekend pulling their hair out and hasn't resolved this yet.
Due to the leap second that occurred at midnight UTC going into July 1st, most of my OEM 12c BP1 agents on Linux servers went haywire, taking up 100%+ CPU on monitored servers. This appears to be due to a bug triggered by the leap second.
The following seems to fix the issue without requiring a server reboot.
as root:
/etc/init.d/ntp stop
date `date +"%m%d%H%M%C%y.%S"`
/etc/init.d/ntp start
as OEM agent user:
$AGENT_HOME/bin/emctl stop agent ; $AGENT_HOME/bin/emctl start agent
I didn't discover the fix, but I've confirmed it works.
Edited by: BrianP on Jul 2, 2012 11:53 AM -- subject changed to note this is a Linux kernel bug, not a Java bug... kernel bug causes software using futexes (like Java) to spin and timeout repeatedly

See MOS note "Enterprise Manager Management Agent or OMS CPU Use Is Excessive on or around July 1, 2012 [ID 1472651.1]" for more information on this issue. Oracle notes it may occur from versions 10.2.0.5 through 12.1.0.1.0.
See also "Leap Second Hang - CPU Can Be Seen at 100% [ID 1472421.1]" and bug 14264454.
Thanks abulloch for getting the note out there!

Also, can someone tell me what is the above number in HEX? I calulated 17155CE0h, is the correct?
