Linux cluster

Has anyone tried to use oracle on a cluster like for example beowolf?

I have not done it myself but I know that Oracle can be implemented on such cluster. At the Compaq web site you should be able to find out info about Linux clusters implemented on their high availability servers.

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.

NSM does not create homedirs in an OES2-Linux-Cluster

Our situation:
The NSM Engine 2.5.1.1 (Jan 12 2010 15:30:55) is running under Netware6.5SP8, on the same server are also a NSM Event Monitor and a NSM Agent. We have a second server under SLES10SP3/OES2a with the Agent and Event Monitor running. While both Event servers can be seen with the NSM-Admin appliction the agent server configuration window displays only the Netware server, and the "eligible agent server" list consists only of Netware boxes.
The Netware and the Linux server contain both the complete replica of all partitions of our NDS-tree. Because we are on transition from Netware to Linux we deploy both Netware and Linux clusters (NCS)
The problem:
On our Netware-cluster (NW6.5SP8) NSM is able to perform all operations (create homedir, move homedir, delete, browse with the Path Analysis tool). Neither does the Linux cluster. No homedirs are created. While the clustered volumes occure in the volume list, with the Path Analysis tool it isn't possible to browse these volumes. No directory tree of these clustered volumes is displayed, but an error message instead: "Policy paths are unreachable". Non clustered volumes on the Linux boxes (including NSS-Volumes SYS and VOL1) can be browsed with the Path Analysis tool.

Hello,
I applied the last updates (no more warning signs in NSM-Admin-Tool) and after this the agent hosted on the linux box is visible in the Admin-Tool.
While rebuilding the volume list the following two kinds of messages appear:

Linux Cluster File System partitions for 10g RAC

Hi Friends,
I planned to install 2 Node Oracle 10g RAC on RHEL and I planned to use Linux File system itself for OCR,Voting Disk and datafiles (no OCFS2/RAW/ASM)
I am having SAN storage.
I would like to know how do i create shared/cluster partitions for OCR,Voting Disk and Datafiles (common storage on SAN).
Do i need to install any Linux cluster file system for creating these shared partitions (as we have sun cluster in solaris)?
If so let me know what versions are supported and provide the necessary Note / Link
Regards,
DB

Linux Cluster File system

Has any seen a release date for oracle's linux cluster file system they announced last week. I am looking at deploying 3 4 node clusters over the next few months and would rather not use raw file systems.

There is the link to the news release:

How could I study Oracle linux cluster ?

Hello buddy:
I want to study Oracle linux cluster. so, where can I get started ? I read online documents, but they not tell you how to build a test enviroument using VMware.
Could you give a hint ?

Purpose is studying.Studying what exactly? Clusters are more than just shared disks.
I want to restablish a single instance and database using OS cluster. The shared disk just can be seen by on node server, then I can manually test this OS cluster and make switching between two nodes at least.This is not really a cluster. A cluster supports scalability - for example, if a process load is too large for a single node, some of it can spill over and be executed by another node or multiple other cluster nodes.
If you talk about standard Linux clustering, that would be running some kind of number crunching s/w (weather modeling, crunching astronomy data, etc) and running this across multiple cluster nodes.
A shared cluster storage system is one possible component of a cluster.
Taking your example - a shared cluster file system is not needed. As the other nodes cannot use that file system (if it does, it can corrupt database files) - only a single non RAC database instance can use the database. Thus the file system can only be used by a single instance on a single server. No clustering needed.
When that server fails, that file system (from the storage server) needs to be mounted on another server and the database instance started on that server.
This is not really a true cluster - simply a high availability and redundant configuration using multiple servers.
If you want to study actual real clustering - do some research using Google. Create a simple project like calculating pi for example and create a virtual 2 or 3 node cluster that run this processing in parallel - using a shared cluster file system for data storage.

Thanks in advance ...

Check the documentation of the clusterware product you are using. It will explain how to run commands on failover.

Oracle10g on linux cluster

Hi;
Picture this, we have 3 server and they are cluster. Let us call those server A,B and C... We want to make oracle10g works on server A and when server A is gone oracle10g on B server take place of A, if server B gone too, oracle10g on C server take place of B....
Anyone has experience about it or advice me notes? i can find only this notes:
http://www.perftuning.com/pdf/white_paper_linux_cluster.pdf but i need one clear one or clean steps
Thanks a lot

Regards,
HusseinHi Hussien;
Thanks for quick replay. I am already following this note :) Could you help me about understand this note clearly please. During the note, there are those steps for oracle dba:
1.Install Oracle software on both nodes and create an Oracle data
2.Prepare quorum devices on shared storage.
3.Install the Red Hat Cluster Manger Suite software.
4.Setup the Linux Cluster.
5.Define the Oracle Service.
From upper note, as i understanding ; step 1 and 5 are related wiht me.... Again during the note part:
Install Oracle software on both nodes and create an Oracle database It says this
Install the Oracle 10g binaries on both servers. Do not create a database at this time. We will create the database after we have installed the binaries. Make sure that your Oracle home is set to a local, non-shared, directory. It is not advisable to install the Oracle Binaries on a shared partition at this time.
After the Oracle binaries have been installed, run netca to create a basic listener. This should be run on both servers in the cluster.After the Oracle binaries have been installed, run netca to create a basic listener. This should be run on both servers in the cluster. To create your database you will need to have the shared storage LUN mounted to both nodes in the cluster. Run dbca to create the database. Choose the mount point for the shared storage as the location for the Oracle files.
1. By this +"Install the Oracle 10g binaries on both servers. Do not create a database at this time."+ i just install oracle 10g to all nodes?(On installation steps i will choose Oracle Enterprice Edition(877 Mb),then general purpose on next screen and intall it?)
2. By this "+After the Oracle binaries have been installed, run netca to create a basic listener. This should be run on both servers in the cluster.After the Oracle binaries have been installed, run netca to create a basic listener."+ As i know when i install oracle 10g its create listener too, so then why i have to need create again?(Oracle binaries=Oracle Enterprice Edition(877 Mb) if i choose it??)

Moving a NetWare iPrint installation to an OES/Linux cluster

Hi folks,
I have an iPrint installation on my NetWare 6.5 cluster that i want to
move to my OES/Linux cluster. The two clusters are completely
independent at present, and need to remain that way. Is there any way i
can move printers and drivers without recreating them and manually
duplicating the settings?
Thanks,
Paul

How to install a parallel Server in a linux cluster

Hi, I'm from O'Porto University and we are trying to install a Oracle 8.1.5 Parallel Server on a Linux Beowulf Cluster.
Do any body have some ideas or documentation that can be useful.
Thanks.

OK.
Next I put the question I see in the oracle site in a paper that parallel server on linux is not available, and this question is being solved by the implementation of new funtionalities from the linux kernel.
Thanks.

Linux cluster, no single point of failure

I'm having difficulty setting up a Business Objects cluster in linux with no single point of failure. Following the instructions for custom install I am ending up connecting to the CMS server on the other server and no CMS running on the server i'm doing the install on. Which is a cluster, however we only have CMS running on one server in this scenario and we can't have a single point of failure. Could someone explain how to setup a 2 server clustered solution on linux that doesn't have a single point of failure.

not working, I can see my other node listed in the config, but the information for the servers state that the SIA is available, I've checked network/port connectivity between the boxes and SIA is running and available for each box.
Via the instructions for installing on a system with windows capabilities I read about a step to connect to an existing CMS.
http://wiki.sdn.sap.com/wiki/download/attachments/154828917/Opiton1_add_cms3.jpg
http://wiki.sdn.sap.com/wiki/display/BOBJ/Appendix1-Deployment-howtoaddanotherCMS-Multipleenvironments
via the linux install.sh script, no matter what I do I'm not coming across any way that allows me to reach that step.

Advice pls OES Linux cluster iSCSI drives separate NIC

In order to improve backup performance I am thinking of connecting our iSCSI drives (on Synology NAS box) to the 2 OES 11 Cluster servers via their second network cards. I.e. the iSCSI drives will be on a separate network so the data is not travelling over the same network twice in order to get to the backup server (Backup Exec on Windows).
I would welcome general comments on any pros and cons of this idea
Not being a network expert I am not sure how I can do this. As I understand it the second network cannot be in the same subnet as the main network or confusion reigns. However my cluster resources will have to be in the main subnet range. Is it that the iSCSI portal addresses can be on a different subnet but everything else is on the main subnet? Will I have any issues if I change the IP addresses of the iSCSI Initiators?
Thanks in advance

Since searching for cluster advice regarding iSCSI brings up this post near the top (!) I thought it worthwhile asking this secondary question to make this thread more of a reference.
Looking at previous OES Netware guide to using iSCSI in a network (8 years old but the closest thing to what I was looking for) it suggests that the iSCSI target (I think I mean initiator here - volumes are on a NAS box) is set up as a cluster resource with associated load and unload scripts. The documentation for iSCSI implies, but does not state clearly, that the iSCSI initiators should all be set up and connected beforehand. Presumably the assumption is that automatically or onboot connected initiators would already be connected.
Seeing as I hope not to have to do much with the system for weeks on end I am concerned that something could happen to the Nas box/network etc whilst the servers remained up so that connections would be lost at some point. Come the failover the iSCSI targets would not be there so all pool resources would fail to connect.
To that end I want to add, and I think as separate resource, a script to attempt to connect the iSCSI initiators in case they are not connected but not to fail if they already are. My proposal is this
#!/bin/bash
. /opt/novell/ncs/lib/ncsfuncs
ignore_error iscsiadm -m node --loginall=automatic
exit 0
which seems to work. In our simple 2 node network I may as well connect all with the advantage that the script does not need to be changed if we add further pools. (we have 2 pools each with 2 volumes which goes against some unexplained 'best practice' notes in the documentation). No point in testing for failures which might be hard anyway as there is presumably an error if they are already connected.
The unload script just has exit 0 .
Any comments or issues I should be aware of?

GW8 linux cluster need to delete WebAcc Agent

What are the steps to correctly remove a GW8 webaccess agent that is in the same cluster resource as the owning domain?
Is there anything special other than deleting the object in C1 and deleting the file system?
do I need to modify scripts or gwha.conf file?
thanks

Yes, gwha.conf editing is needed (remove the entry for your gwinter).
Finally, if you care, you can uninstall the gwinter rpms.
