similar to: Is the order important when installing ocfs2 and Oracle RAC?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Folks, I'm trying to wrap my head around something that happened in our environment. Basically, we noticed the error in /var/log/messages with no other errors. "Mar 16 13:38:02 dbo3 kernel: (3712,3):o2hb_do_disk_heartbeat:963 ERROR: Device "sdb1": another node is heartbeating in our slot!" Usually there are a

We have a test 10gR2 RAC cluster using ocfs2 filesystems for the Clusterware files and the Database files. We need to increase the node slots to accomodate new RAC nodes. Is it true that we will need to umount these filesystems for the upgrade (i.e. Database and Clusterware also)? We are planning to use the following command format to perform the node slot increase: # tunefs.ocfs2 ?N 3

RHEL 4 (CENT OS) Am I waisting my time trying to get the 10G Clusterware installer to use OCFS2 volumes for the voting and OCR disks ? The ocfs2 setup seems happy on both nodes but the 10G installer says the location entered for the oracle cluster registry (OCR) is not shared across all the nodes in the cluster Do the volumes need to mounted ? I did with no change . [root@green rc5.d]#

I have been a user of OCFS2 for quite some time now (2 years or so) and a user of Oracle RAC for several years as well. My usage of these two is completely independent though, the cluster filesystem is for application level usage (web servers, etc.) only because RAC can manage its own shared storage directly. And that brings me to my observation/question... I keep seeing a lot of messages

Howdy, I am trying to setup a 10gR2 RAC on top of some nbd devices. OS is Centos4.1/i386, (2.6.9-11.0.0.10.3.EL, ocfs2-2.6.9-11.0.0.10.3.EL-1.0.4-1). ocfs2 setup went perfectly well, btw. (besides the fact that ocfs2console apparently ignores nbd disks) mount says /dev/nbd1 on /opt/oradata/data1 type ocfs2 (rw,_netdev) on both nodes ls says (after runInstaller was started, so the files were

hi, i am trying to install oracle rac on fedora core 6 through iscsi. when i try to mount, mount.ocfs2: Invalid argument while mounting /dev/mapper/rac-crs on /mnt/crs.

Hi team I had installed OCFS2 on RHEL5.0 . every thing looks fine but when I was installing CRS on the node I got error message OCFS2 is not supported. Can you please put some light on this.

hello everybody I successfully installed a *very* small two node cluster with a shared volume on linux (both debian, one x86, one ARM [laugh not: NSLU2 :)]). before that, I tried to install the "clusterware" package on my windows xp box and it constantly complained about the three different ip addresses it wanted to see, then I got so frustrated with numerous manual hosts-file

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Folks, We would like to evaluate how ocfs2 will work with a debian distribution. Most of our systems people favor debian and so we are evaluating whether debian and ocfs2 work nicely + oracle 10gR2 rac. I know that debian is not supported by Oracle, but this is only for testing. Has anyone had experience with this? If so can you provide

Hi list, today, I installed a two node Oracle 10g RAC system on SLES9 SP2 RC2 which shares (via a SAN) a database volume and a quorum (ocr and voting). This volumes are formated with ocfs2 - so far no problem. At the moment I'm stuck with the mounting of these volumes at boot time. The user-guide of ocfs2-tools mentions to add the corresponding lines to fstab - but at the time when fstab

Hi, The oss.oracle.com website has the following statement: OCFS2 certification with Oracle 10g Release 2 RAC on Linux x86, x86-64, Itanium and Power is currently in progress. Is there any indication when this process will be completed? We have a customer in NZ that wants to use OCFSv2 for the OCR and voting files with 10.1.0.4 RAC on RHAS4.0 Linux x86-64. They do not want to use raw devices

Hello, I am facing a problem during root.sh of 10g Release 2, on RH 4.0 update 1 + ocfs2.

Hi, I'm setting up a 2-node Oracle 9i RAC on OCFS2. But I have some problems with understanding how the shared Oracle_Home is being used. For instance there is the *$ORACLE_HOME/oracm/admin/cmcfg.ora* file. The $ORACLE_HOME is on the SAN so the 2 nodes have access to this file. How will the settings then be done per node? Is there a guide/tutorial/howto for installing Oracle 9i RAC on

We wan't to setup two Oracle instance and make RAC work on them. Both VM are setup based on libvirt + KVM, we use a lvm lun which formated in qcow2 format and set the shareable properties in the disk driver like this: <disk type='block' device='disk'> <driver name='qemu' type='qcow2' cache='none'/> <source

Caveat: I know nothing in particular about Oracle RAC, but... Assuming that RAC uses something like SCSI reservations in order to share the disk, I would guess it doesn't like the disk being on the IDE

Hello, I've successfully configured RAC on Redhat AS, with external firewire + ocfs. The whole process was done without any errors and have created the database. (Thanks to Wim Coekaerts useful article). But now, how do I actually use it? If I have a client making a connection, to which node do I connect? Are there also any recommended procedures to test RAC's capabilities? Thanks.

Wim, Thanks for your prompt response on this. The tpmC figures look very impressive, and tpmC is read intensive. I had already read note 236679.1 "Comparing Performance Between RAW IO vs OCFS vs EXT2/3" which I guess is the article to which you are referring; it made me suspect that the poor performance was due to the lack of an OS IO cache but I wasn't sure. The database is
