Memory hot plug supported in Oracle linux 6.0 ?

hi,
I am testing Oracle Linux 6.0 on a vm, I tried to hot add memory, but i noticed that the respective modules like acpiphp and acpi_memhotplug not present.
Also i got the below information from the site, http://blogs.oracle.com/wim/2010/10/playing_with_sr_iov_in_oracle.html
"----------To enable pci hotplug in the guest, please do the following :
in the guest you have to load both pciehp and acpiphp
you can do this easily by doing :
**echo "modprobe pciehp" >> /etc/rc.modules
echo "modprobe acpiphp" >> /etc/rc.modules
chmod 755 /etc/rc.modules**
note - this is for testing purposes only. We do not currently have official support in the product for this.--------".
I tried doing the above mentioned procedure, then also the mem-hot plug is not working.
So I feel mem-hot plug is not supported.
Can any oone confirm me about this.

Does weblogic server 10.3.6 & 10.3.5 supported on oracle linux 5.8 ?

I am trying to install weblogic server 10.3.6 on Oracle linux 5.8 (64-bit) platform. While creating domain , it does not take any input in password & conform password fields on "configure administrator username and password page". The field remains blank. I am stuck at this point and not able to create domain. The same issue is with weblogic 10.3.5 server. The java i used is jdk1.7 update 3 and jdk 1.6 update 27. In Both the cases i am not to create domain.
Can anyone of you tell me if weblogic 10.3.6 is supported on Oracle linux 5.8 platform. If it is supported any idea how to resolve this issue?
Thanks in advance,
Padma

Yes. Please refer

Or does it mean that I must pay Oracle in order to be able to get these packages in order to learn ASM at home ??
Why would Oracle allow us to use their RDBMS/RAC/ASM/Linux software at home learning for free and not supply the above two packages??If you want to use ASM for free, install Oracle Linux 5 Update 7 and download the RHEL5 oracleasmlib package from here:

Keep in mind that Database is NOT certified on Oracle Linux 6 anyway, so it is challenging to install. The very article you link to uses Oracle Linux 5. It also links to these very same RPMs. If you follow the article more carefully, you won't have any issues.

JDeveloper 11.1.2 install on Oracle Linux 6 U1 64 bit

I am trying to install jDeveloper on Oracle Linux 6 U1 (6.1) and keep getting a variety of errors. I know that jDeveloper does not support 64 bit Operating Systems very well. However with the majority of new systems being 64 bit and the memory limitations of 32 bit is jDeveloper going to move into the next century and support 64 bit jvm's and operating systems natively? When will this happen?

I've been running JDev using 64-bit JDKs on OS X and Linux for a few years without issue.
You might be having issues with JDeveloper on Oracle Linux 6, however - the WebLogic install scripts, etc. do not include support for Oracle Linux 6 as of yet, nor Java 7.
Take a look at the certification matrix for operating systems and Java versions in JDeveloper:

Installing OBIEE 11.1.1.60 on 32-bit Oracle Linux 6.3

Hello,
I am presently trying to install OBIEE on a 6.3 Linux and have run into the "Your OS is not supported" error, during installation.
Has anyone successfully installed on 6.3? I checked the prereq's and it seems to be only supported on Oracle linux 5 (32bit)
Sidenote:
Before realising it's an unsupported OS, I went through the installation process and encountered the error:
"error invoking target agent nmb nmo nmhs of makefile" and it was only through a process of elimination that I encountered the unsupported OS and thought it could be related.
Appreciate any help.

As a temporary measure try deleting the environment variable HYPERION_HOME, you can always put it back if it doesn't work out.
Cheers

New Oracle Linux 6 installation - ASMLib and EMC Powerpath - is it possible

Hi everyone,
I would like to ask whether that latest version of Oracle Linux 6 can be used for a new installation (one that will replace Windows) to serve as that basis for Oracle RAC.
The storage is a high-end EMC Clariion.
I want to use the Unbreakable Enterprise Linux 2.
I would like to use EMC Powerpath, but it seems this is not yet available (or at list not present in the current EMC support matrix).
I want to use ASMLib, but if have to use redhat compatible kernel (so that I can use Powerpath), I will not be able to use ASMLib (AFAIK).
Does anybody has experience with this problem? What would you recommend?
I'm putting a list of possile options that I am aware of:
1. Use OEL5 with redhat compatible kernel (use Powerpath and ASMLib).
2. Use OEL6 with UEK2 kernel, but don't use Powerpath (use dm-multipath and ASMLib)
3. Use OEL6 with redhat compatible kernel (use Powerpath and don't use ASMLib, but use udev for persistent device permissions and naming)
4. Use SLES11 (with Powerpath and ASMLib)
do you have other suggestions? do you have comments on the pros and cons on this options.
Can someone from EMC or Oracle comment on the plans to make Powerpath available for OL6 with UEK2 ?
Regards,
Mihail

I could test "OEL6 with RHEL kernel + Powerpath" vs "OEL6 with UEK2 kernel + dm-mpio", but anyway this would not give the answer whether Powerpath is faster or slower than dm-mpio by itself, since the kernels would be different.I wonder how the answer whether EMC Powerpath or DM Multipath is faster can help you? Apparently you cannot use Powerpath with the UEK2 kernel and have a certified system at the same time, at least not at this time. However there is no reason to throw the towel yet. If the use of Powerpath instead of Multipath is so critical, why not using Oracle Linux 5.7, which is certified? If you check the EMC compatibility matrix (esm_by_os), it actually shows some systems including Clariion supported for Oracle Linux 6.2 with UEK kernel. You might want to take a closer look.
Anyway, it doesn't look like you will be able to solve the performance question without doing a real world test in your environment. You have no indication that Oracle Linux 6.3 with DM Mutlipath will give you less performance than RHEL 6.3 with Powerpath. Regarding the information you found, Linux is not Windows.
Powerpath is not free and you have to pay a license, but worse, it will tie your system to a very specific version of the kernel. In case of RHEL 6 or later, it will deny you the use of Oracle specific products and features such as ASMLib, etc. Multipath seems to be the more economic and better solution since you do not have to worry about kernel versions and have the freedom to use whatever Oracle Linux has to offer.
So, do you want to limit your kernel features and options and fix a problem that you don't know even know if it applies and pay money for it?

Use Oracle Linux packages to fix GHOST: glibc vulnerability on RHEL4

Dear All,
It is the first time I use the discussion function. Hope someone from Oracle supprot team can help me.
P.S. I have Oracle support CSI for DB but I don't find whhich category I should submit my question.
Here is the our case.
Our user is still running RHEL 4.8(9) on some servers. For some reason, they don't want to upgrade them at the moment. As you know, GHOST: glibc vulnerability has been announced recently. For RHEL4, they have to purchase ELS subscription to download the packages even though they have the license. Our user doesn't want to pay for that. Meanwhile, we find Oracle Linux provides a package to fix the problem. We told them this finding and they would like to use Oracle Linux patch.
But to better explain the situation to them, we want confirm with Oracle about several points.
1. The patch can be downloaded and used for free but there is no support from Oracle,right?
2. Is it possbile to have the support from Oracle in such case - The OS is RHEL4.8(9) and some patches are provided by Oracle?
My understanding is that there is no supprot. Please help to confirm.
Thanks and regards,
Alpha

Please note that this is a user forum. You may find responses from Oracle here, but not necessarily.
To assume that Oracle would provide support for RHEL, just because you install a OL package, is a pretty wild assumption. I'm not aware that any vendor would provide support for another vendor. Nevertheless, OL and RHEL are 100 % user space and binary compatible, and so are the packages, unless you install anything that requires the Oracle UEK kernel or any other vendor specific product that is not GPL.
If you want to stay with Red Hat you will have to pay for support to Red Hat, or convert your system to Oracle Linux and you can install and download patches and errata for free. See Switching from Red Hat Network to Unbreakable Linux Network (ULN) . OL provides patches and errata for free through Oracle Public YUM. If you need support for Oracle Linux from Oracle technical support, you will also need to buy a subscription to ULN.

Is VMPlayer3 supported by Oracle DB 11gR2 RAC system ?

Folks,
Hello. I have been running Oracle regular ( a single instance) Database 11gR1 successfully with Oracle Linux 5.6 as Guest OS in VMPlayer3 and with Windows 7 as Host OS for a long time.
Now, I am installing Oracle Database 11gR2 RAC system (2 nodes) in the same environment that is with Oracle Linux 5.6 as Guest OS in VMPlayer3 and with Windows 7 as Host OS.
I have installed Clusterware for 2 nodes. But it seems that VMPlayer3 is not supported by Oracle DB 11gR2 RAC system.
Only VMware Server 2.0.2 is supported. When I install VMware Server2.0.2 in Windows 7, the error message comes up as follows:
"Setup has detected that VMPlayer is already installed on this machine. Please uninstall this product through the Control Panel and try again."
This means we cannot installed VMPlayer3 and VMware Server 2.0.2 in one OS Windows 7. I have installed many VMs in VMPlayer3 and cannot uninstalled VMPlayer3.
My questions are:
Can any folk make sure whehter VMPlayer3 is supported by Oracle DB 11gR2 RAC system or not ?
If not, how to solve the issue that VMPlayer3 and VMware Server 2.0.2 cannot be installed in one OS Windows 7 ?
Thanks.

Folks,
Hello. As I know, VMPlayer 3 supports Oracle Linux 5.6 as Guest OS and Windows 7 as Host OS.
But when I am installing Clusterware and running the script root.sh, the error message comes up as follows:
"ADVM/ACFS is not supported on Oracle Linux-release-5-6-6.0.1".
My questions are:
First, what is ADVM/ACFS about ?
Second, can any folk make sure whether Oracle DB 11gR2 RAC system is compatible to run in Oracle Linux-release-5-6-6.0.1 in VMPlayer 3 with Windows 7 as Host OS ?
Thanks.

Oracle VM Manager 3.3 on Oracle Linux 7?

Hi All,
Is Oracle VM Manager 3.3 supported on Oracle Linux 7?

That's true, but OVMM has surely been in development/testing prior to June. In fact, I saw the first announcement of OVMM 3.3.1 beta somwhere around march.

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)

Oracle Linux as Guest OS in Oracle VM (which all kernel are supported.)

Hi,
currently Oracle packages two different kernels with Oracle Linux (Redhat compatible kernel and UEK). so when running Oracle Linux as guest on Oracle VM server which are the kernel are supported???
Thanks,
Inbaraj

Thanks for your reply... i understand that Oracle kernel is better than Red Hat compatible kernel, but RHCK is still bundled with OL , that's where my question started whether RHCK is supported as guest in OVM?

Oracle supported flavours of linux

My company is planning to shift all it's oracle operations on to
linux. We do not know which distributions of linux oracle
supports. we work in products like oracle database, jserver, ias
etc. Can you please suggest the distribution of linux we can go
for.
Thanx in advance,

It seems to me as though they all will work but none will
install perfectly cleanly. Each distribution is addressed in
this forum in one way, shape or form. The baseline supported by
Oracle is SuSe but folks in this forum have successfully
installed on Red Hat and Mandrake as well as others. Whichever
distribution you choose do a search in this forum on the
distribution name and browse the posts that are returned. Some
will sound like the end of the world and others have solutions
to common problems.

Oracle Linux support subscription. for Oracle employees

I am using RHEL 5 but could not find wireshark trace and I beleive that you need to have Oracle Linux support subscription to access yum repositories. How an Oracle employee can update the software?

Here is a previous link that could be interesting to you:
Re: Employee Access to ULN or Public Yum?
You can also install wireshark and dependend packages using oracle public yum by following the instructions on
http://public-yum.oracle.com/
# yum install wireshark
# yum install wireshark-gnome

Does Oracle Linux Server-uek Kernel support KVM? (OL6)

Hi,
I've installed Oracle Linux 6. Does it support kvm? How do i check if module kvm is running? modprobe kvm does not show me anything, neither in /var/log/messages or dmesg.
Regards
Ricardo

Just boot with the base kernel... instead of unbreakable enterprise kernel. after that if you modprobe kvm the check dmesg and you'll see something like this:
kvm: 4864: cpu0 unimplemented perfctr wrmsr: 0x186 data 0x530079
