See an HBA interface in a Virtualized Oracle Linux 6.3
Hi all,
I have a pool of 6 virtualized machines. Those machines are connected to a storage throug a fiber optic switch. I want to see from one virtualized machine a backup library which is also connected to the fiber optic switch.
I would like to know how my virtual machine would be able to see that backup library. I guess I would have to configure something in OVM Manager.
Best regards
Woow man, then I have to modify the way to proceed....
As you have seen SRVDAR01 has two dual port HBA pci device in two different PCI slots. That makes the four fibre channel ports I showed in one of my answers....
04:00.0 Fibre Channel: QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA (rev 02)
04:00.1 Fibre Channel: QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA (rev 02)
07:00.0 Fibre Channel: QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA (rev 02)
07:00.1 Fibre Channel: QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA (rev 02)
Then I would have to:
As I am using one fibre channel from one HBA and one fibre channel from another HBA, in order to have redundancy, I shall first Identify clearly the fibre channel ports which I am not using.
Then connect the two free ports to the brocade through fiber optic cables.
Make the WWN assignation in order to MAP the backup library to these free ports.
Follow then the steps you told me in one of your answers:
Prepare SRVDAR01 with the steps showed in the link: https://forums.oracle.com/message/10329576#10329576 so that I would be able to execute modprobe xen-pciback. That means the modification of the grub and a reboot.
Manually attach the pci-device to the guest after it has started using Xen's pci-attach command on the command line like this: xm pci-attach "id of my guest" 0000:07:00.0
And after all that work, although the procedure is correctly executed, it might not work....
Let's see if it worth to do all this job. Thanks again!!

Oracle Linux Remove Old Kernels
I was just wondering if Oracle Linux by default removes old outdated kernels when I run 'yum update' command? I see new kernels getting installed consistently however I never see any kernels being removed like I expect to see in RHEL as a new kernel is downloaded. Is there a way to see which kernels are installed on my Oracle Linux 6.3 server and how I can remove them so they don't clutter my Grub screen and system?
You can check the grub boot menu, which normally has an entry for all installed kernels:
<pre>
# cat /boot/grub/grub.conf
</pre>
Or query the installed kernel packages:
<pre>
# rpm -qa | grep kernel
</pre>
To remove a kernel, use the YUM utility:
<pre>
# yum remove kernel-package
</pre>
For instance:
<pre>
# rpm -qa | grep kernel
kernel-uek-2.6.32-200.13.1.el5uek
kernel-uek-2.6.32-300.10.1.el5uek
kernel-2.6.18-274.el5
kernel-uek-devel-2.6.32-200.13.1.el5uek
kernel-headers-2.6.18-308.el5
kernel-2.6.18-308.el5
kernel-uek-firmware-2.6.32-300.10.1.el5uek
kernel-uek-devel-2.6.32-300.10.1.el5uek
# uname -r
2.6.32-300.10.1.el5uek
# yum remove kernel-uek-2.6.32-200.13.1.el5uek
</pre>
The example above is for OL 5, but works in OL 6 as well. -
Installing Oracle Linux 5.8 on Virtual Box
I'm trying to install Oracle Linux 5.8 on Virtual Box. I have downloaded V31120-01 and burned to the DVD, I think successfully.
However, when I start the Virtual machine, I get the Opening screen, "Oracle Linux" the little picture of the penguin guy, etc, so I think my DVD is good.
The screen says, "To install or upgrade in graphical mode, press the <enter> key." So I do.
Several lines of text flow across the screen, but then the process seems to stop with no prompt on what to do next or any indication that an error has occurred, it just stops.
The last lines I can see are:
ACPI: bus type pci registered
PCI: Using configuration type 1
ACPI: Interpreter enabled
ACPI: Using PIC for interrupt routing
ACPI: No dock devices found
ACPI: PCI Root Bridge [PCI0] (0000:00)

I'm not sure if it's waiting for some input from me, or if there is a problem, but nothing happens beyond this point until I power down the virtual machine.There is no need to burn a DVD because Virtualbox can directly mount and boot from the .iso image you downloaded. It is usually a good idea to check the md5 checksum of your download with the number provided by the download page to verify your download is not corrupted. There are no problems installing any version of Oracle Linux under Virtualbox provided you have the right hardware. I suggest to check the Virtualbox documentation.

Enable hyperthreading for virtualized Oracle 11gR2 database (OEL57 64-bit)?
We are virtualizing our Oracle 11gR2 databases (running on OEL57 64-bit) on Vmware 5.1. I've read information at various locations that hyperthreading is not recommended for Oracle 11g database. One example is here, however, I seen many more:
http://bryangrenn.blogspot.com/2011/08/hyperthreading.html
My issue is that Vmware themselves recommends enabling hyperthreading for virtualized Oracle databases in their Oracle Databases on VMware Best Practices Guide.
Does anyone have any practical experience with this issue that can be shared? What are the advantages and disadvantages of enabling hyperthreading for our virtualized Oracle 11gR2 on OEL57 64-bit virtual machines
Thanks, Fred

If you read the comments on that blog you will see that the results are highly dependent on the type of CPU.
The effects can also be dependent on the nature of the workload: you may have CPUs that are fine with an OLTP workload, but don't scale as you might hope with a DW workload.

How to see new disk in oracle linux 5
Dear,
i am using oracle VM and created 2 guest OS (both Olx5) i also created a shared disk and assigned to both linux servers.
question: how can i see the disk in each server. using fdisk -l it just shown the one there before.
in HPUX we have ioscan to detect new devices. is there away to check for new disk in oracle linux.
Thanks in advance.
Tomfdisk -l shows only existing partitions. So if your new disk has not partition created it will be not shown in the output.
AFAIK there is not such command which will list all devices but there are several ways how to find the devices. All informations you can find in /proc directory (fdisk -l reads /proc/partitions when device is not passed as argument).
You can find devices (local disks) for example using following commands (hope it helps):
cat /var/log/dmesg |egrep 'sd[a-z]: s|hd[a-z]: h'
cat /proc/diskstats |egrep -v 'ram|fd'|awk {'print $3'} -
Oracle Linux 6 installation FAILURE on VMWare virtual machine
I just downloaded OEL 6.0 x64, created a new VMWare virtual machine (I have many VMWare VMs running various flavors of OEL 5) and did an installation. It all seemed to work fine. I was just testing, so I didn't do any customization. It finished, and looked good, just like all the other ones I've done. I clicked "reboot", and it did. Or it tried to.
It did boot from the disk, but after about 15 seconds, it said:
No root device found
Boot has failed, sleeping forever.
I retried the installation using a fresh VM, and even let the installer check the whole DVD first. Same result.
Anyone installed OEL 6 to a virtual machine on VMWare ESX?
Any idea what the heck could be wrong?The problem is:
The Red Hat compatible kernel includes the vmw_pvscsi driver whereas Unbreakable Enterprise Kernel doesn’t. The kernel that the installer boots first does have the drivers, which is why everything is set up fine until UEK tries to find the root volume. It's an issue we plan to address in an updated kernel.
For now the workaround is:
When creating a new VM in VSphere, do not pick Red Hat Enterprise Linux 6 x86-64 as the OS type but use Oracle Linux 5 x86-64 (or Red Hat Enterprise Linux 5). ESX will then expose the LSI logic scsi controller to the OS and the 2.6.32-100.28.* kernel will work.

How to install graphical desktop interface on Oracle linux server 6.2
Hi
I have installed Oracle Linux server 6.2 how i install graphical desktop interface on server class installationIf this is in the very early stage I suggest to re-install the OS.
Look out for the window to select the set of software to install. Leave Basic Server selected, but choose the Customize now ratio button. Select the Desktops group on the left side of the window. Choose at least the X Window System, Fonts and Desktop packages. To get a similar Desktop like in previous Enterprise Linux releases, add also the General Purpose Desktop and Graphical Administration Tools packages -

hi i have the 1st gen apple tv and suddenly when trying to rent a movie i don't see the rental interface. i did a factory restore and now i see movie trailors and my movies but not rental option. any idea what could be wrong??
Judging by all the posts on the forum, there seems to be an issue at Apple's end, although they have made no announcement on their status page. Some users have reported that Apple is aware of the issue. You can leave feedback for Apple at the link below.

I do not see the user interface for the Logic Pro software instruments. I can hear them play through my midi keyboard but cannot see them to adjust the parameters. Please advise.
Couple of things - you can open the interface for any instrument or plug-in by double-clicking its insert slot on the channel strip. You can configure Logic to automatically open the interface for a plug-in when you first instantiate it in the preferences. Go to Logic Pro > Preferences > Display > Mixer, and check the box for "Open plug-in window on insertion".

Can not ping oracle linux vm in Virtual Box from my host
Hy
I have setup oracle linux 7 on virtual box including vboxadditions.
But I can not ping this maschine from outside ( it works for my other vm oel 5.8 )
I did systemctl stop filewall.service
Here my Network konfiguration inside my oel7 vm:
/etc/sysconfig/network-scripts/ifcfg-enp0s8
TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=no
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=public
UUID=388ee413-55e9-45e1-be1d-4f5eedc402f3
ONBOOT=yes
IPADDR0=10.20.50.101
PREFIX0=24
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
HWADDR=08:00:27:5F:87:91
Can anyone help?
Thanks
Peter SchlaegerHi,
Before discussing the network configuration of Oracle Linux 7 (By the way; it seams correct), lets talk about the VirtualBox network configuration, So the Network adapter of your VM can be attached to {NAT, Bridged Adapter, Internal Network, Host-only Adapter, ...}, what is the Adapter attached to your NIC?
Make sure the Network Adapter is the same as the your other VM (OL 5.8).
Best regards -
Want to install Oracle Linux Rel.6 and have a graphical interface
After reading:
Does Oracle Linux Rel.6 have graphical capabilities
How do you install the GUI for Oracle Linux Rel 6?Dude wrote:
I'm glad you did not take my remark to call you a Linux enthusiast in bad way. It certainly was not meant to be a bad comment, but it's was probably silly of me to make such a remark anyway. I do not take personally offence easily in a forum like this. No, if you want to offend me, post poor code and claim it as the best thing since slice bread. ;-)
I guess I strive to be liberal, but by definition I don't think I really fit into any political wing.Likewise. Find politics a necessary evil to keep abreast of - such as the election in the US.
Back to Linux and your example, I have used such interfaces for many years too. Unfortunately we often have to use what is provided. However, the reason for the text interface is no longer valid, unless your input device is only a text based terminal.Not as much the input device - heck, pure tty devices are pretty much a thing of the past. It is about the complexity of the infrastructure between you and the device you need to administer. And about the task you need to perform.
The connectivity can mean being unable to run a GUI - due to performance, firewalls, router configurations and so on. The task at hand could very well be easily done, using the relevant o/s commands via a command line interface.
I think there is nothing against a GUI app that runs on your PC to sends appropriate commands to a text interface over a slow serial link, apart from the effort that is required to interact with errors, etc.Much more complex than that. A terminal server is usually used - and it attaches to the serial/RS232 connections of multiple devices that need to be administered. It will typically reside on a separate management network too, and not on the local company/corporate intranet.
So for you to access a device to administer, you need an open firewall to the management network to reach the management server that handles the serial console connection for the device you want to administer. You need a valid o/s account on that terminal server. You need to use ssh to access the command line of that terminal server. You need to enter the relevant command that will attach your ssh session to the RS232 console connection to the device to administer.
There is no GUI app on your side that can not only automagically do all this for you, but also provide you with GUI admin widgets to send commands to the remote device. Even if that remote device being sysadmin'ed is Linux, different distros and different versions of the same distros, means different commands, variances in command line parameters for such commands, and so on.
A sysadmin that cannot deal with such situations, and need a GUI as a crutch to administer a device.. I for one will not call that person a sysadmin. I would call the person incompetent instead. Harsh views perhaps, but being sysadmin is an unforgiving job. A mistake, or inability to access a device and fix it using the bare minimum, could result in severe financial loss for the company. -

Oracle Linux virtual machines failing to boot
We have 2 oracle linux virtual machines on one host machine, both running Oracle Linux release 6 update 2 for X86_64. Both were built identically with oracle 11 installed on them. Both machines were working ok until this morning when the host machine rebooted. After the reboot, the virtual machines now hang during the boot process. The login prompt never comes up. The database does not start up on both machines. The machines are up enough that I could putty into them. In startup.log, the following is listed for the two machines. One is named demo, the other test.

The demo machine is looking for a redo log file. The file does not exist. If that file ever existed, what would make that file disappear? The test machine does not have any redo log files either but the test one is not even looking for it.
