Installing RAC on 11g - Linux 5

I will install RAC on DB 11g in Lunux 5.
I am evaluating hardware needed for the implementation.
I have two server in Linux.
Server 1 - I have My BD 11G
Server 2 - Is my new server for RAC.
Now. I don't understand about the shared storage.
Is necessary buy a shared storage for RAC? because, I have revised in some notes and It mentioned that not is necessary the shared storage. that with server 1 and server 2 can make a RAC with clusterware It is correct.
Thanks,
Guido

Hello,
Welcome to the forums.
Now. I don't understand about the shared storage.
Is necessary buy a shared storage for RAC? because, I have revised in some notes and It mentioned that not is necessary the shared storage. that with server 1 and server 2 can make a RAC with >clusterware It is correct.You don't need to buy a new one if you can create shared disks (which will be mounted on both of your RAC nodes) on your existing available storage in your organization. You have to have shared file system.
following note should be best for you in this regard where you don't need to buy any extra storage but you can use NFS to build your cluster. This article is for 11GR1, but it can also help you for 11GR2

Problem installing mod_plsql oracle 11g linux

Hello and thanks in advance for your help! I want to install an Oracle HTTP Server 11g on a Centos linux server. It seems to be working but when I execute a pls query such as mydomain.gr:7777/pls/smth nothing happens.. Logs of apache show the following error:
[VirtualHost: main] MODPLSQL-00368: mod_plsql: (null) HTTP-404 No procedure specified to run
Until now I have managed to install a WebLogic server and the WebCache server. Should I also install the Database manager so as to configure
mod_plsql?
I edited dads.conf, cache.conf and plsql.conf, and included plsql.conf in httpd.conf of apache for oracle http server.
What could be going wrong?

Try add and set "PlsqlDefaultPage" at "dads.conf". Any PL/SQL procedure, which generated HTML. There is package "PKG_WEB", procedure "list' at this example:
<Location /pls/ddd>
SetHandler pls_handler
Order allow,deny
Allow from All
AllowOverride None
PlsqlDatabaseUsername
PlsqlDatabasePassword
PlsqlDatabaseConnectString DB1.WORLD
PlsqlAuthenticationMode Basic

Problem on Installing RAC System - Oracle Linux 6.2 and 11gR2

Folks,
Hello. I just start to install 4-nodes RAC system using VMplayer 3. The host Operating System is Windows 7.
The Guest OS is Oracle Linux 6.2.
Because my computer's hard disk does not have enough space, I install the Guest OS Oracle Linux 6.2 into a external hard disk. But its speed is very slow. It has taken more than 24 hours by now, but still don't finish installing Oracle Linux 6.2.
Do any folk understand what's going on ? Is there any problem on Oracle Linux 6.2 ?

Installing RAC on Oracle Linux 6.3 using VMWare ESX

Hi
I have configured a pair of Linux servers following a guide on Oracle-base.
Both servers have their own OS disks and they have four virtual disks that are shared between the two vm's (configured as sharable in VMWare using a separate SCSI controller to the OS disks etc.
The /u01/app/11.2.0.3/grid/root.sh script is failing at what appears to be the part where the daemons are added to the inittab the error i get is :
CRS-4124: Oracle High Availability Services startup failed.
CRS-4000: Command Start failed, or completed with errors.
ohasd failed to start: Inappropriate ioctl for device
ohasd failed to start at /u01/app/11.2.0.3/grid/crs/install/rootcrs.pl line 443.
I have found a few notes of the Internet suggesting disabling IPv6 (It's already disabled)
Restarting syslog
and removing some file in varoius tmp dirs (there were none)
But i'm getting the feeling the issue is with the shared disk config.
Can anyone point me to log files etc so i can troubleshoot this further?

I guys I have run into same problem. Is there a solution for this or not.
OS: OEL 6.3 x86_64

Installing RAC on Linux 9.0

Hi friends,
I tried to install RAC on two intel based pc with 80gb firewire drive on Linux 9.0.
But, I could not succeed. I was wondering if someone please tell me that it is possible to install it on LINUX 9.0 because I cannot afford Linux AS 2.1.
I follow oracle documentation, Werner Puschitz Documents, I also follow Rampant press book "Installing RAC..". But no one really helps me as all they are talking about Linux AS 2.1.
Pleased help me in this. I really appreciate it.
Thanks and have a good day.
Bhavin
thanks.

hi,
It was solved by reinstalling the Cluster Manager. so please ignore this post.
Thanks

Install Oracle Database 11g release 2 on Oracle Linux 6.0?

I'm running Oracle Linux Server 6.0, and am trying to install Oracle Database 11g release 2 on it. The installation is failing because it says I need "glibc-2.3.4-2.41", but I think the OS came with glibc 2.12.
How do I upgrade glibc on this machine to glibc-2.3.4-2.41?

Thanks. What's UEK?UEK = Unbreakable Enterprise Kernel. It is installed by default with Oracle Linux 5 Update 7. Also, if you install the oracle-validated RPM (as part of the initial install or via yum afterwards), all the pre-requisites for installing database will be taken care of for you.

Installing RAC in Solaris 10 T2000

How can I create a shared file system using a Oracle cluster or a Sun Cluster software, the hard drive are locally in the T2000 server and I created 2 domains using the ldm.
ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv- SP 4 1G 1.1% 73d 23h 12m
racdomain1 active -n---- 5000 9 3000M 0.0% 9m
racdomain2 active -n---- 5001 9 3000M 0.0% 9m
Can you send details how can I create the raw devices and data files file system ?

mrosa001 wrote:
I have some more questions:
How can I have the raw device shared by 2 servers?Yes - if the device/LUN is shared between cluster nodes. In other words, each cluster node need to see the same device. Once that is done, you can simply partition the device (if needed) and turn that into a raw device.
You will however need to configure the raw device entries (a file called +/etc/sysconfig/rawdevices+ on Linux) on each node.
Remember that you need 5 raw devices typically - 2 for the OCR and 3 for the Voting Disks.
Not sure about Solaris, but raw devices have been deprecated on the Linux 2.6 kernel as block devices can now be opened using direct I/O. Oracle recommends not using raw devices on Linux anymore. Not sure if this applies to Solaris. If it does, then 10g CRS Installer have a bug that prevents it from using block devices - forcing you to use raw devices (and then change it back to block devices after CRS has been installed). Or, you may find it easier to install 11g CRS instead and run 10g RAC on it (a certified Oracle combination).
Do I have to install ASM before the Oracle Clusterware SW?No. You install CRS first. Once that is installed correctly and successfully, then install RAC. I prefer installing RAC without checking any "+create db+" options.
Once RAC has been successfully installed, use dbca to create the ASM instances. Once that is done, create the the RAC database and instances.

How can i install oracle 10g on linux cluster

Dear all:
please advice How can i install oracle 10g on linux cluster service ..
thanks ,,

Without RAC, you can only have one instance manage the database. One instance = one set of processes communicating via IPC.
Unless you know of a way to have processes use memory-based IPC across nodes, you need to pick a node and install & run the database software on that node.

I think the installation of Oracle database under Oracle Linux is the least troublesome because you an install the "oracle-validated" package, which takes care of software prerequisites and system parameters. Enterprise Linux is however not suitable for Desktop and Laptop systems. For the purpose of development or evaluating Oracle products I suggest to use Virtualbox http://www.virtualbox.org. If your system is too old or not well equipped to support virtual systems, consider a hardware upgrade or try the howto's above.

Can I install RAC in my pc computer?

I am learning RAC, trying to install RAC on my PC computer.
Both computer are dell, same configuration, and each computer has two network cards.
I have another USB external hard disk, used for the storage, is that doable?
Now I will try to install linux + oracle 10g + 10g RAC, is that doable?
do I need other hardware or software?
appreciated for any suggestions.
Thanks.

The easiest would be to install the virtual software like Virtual Box(free and from Oracle) ad install RAC using it. If you want to physical machines, try to arrange a third machine whose disk you can use as a shared hard drive using a software called Openfiler( http://www.openfiler.com/) . This would be closest that you would be able to get to a production box. If you really want to spend money than you can buy an old shared storage from Ebay.
