Hi, I am trying to install Oracle 9i RAC on SLES 8 SP3 with a shared firewire disk. I am using the following OCFS: OCFS Release 1.0.11-1 for suse sp3 2.4.21-138 smp kernel ocfs-2.4.21-138-smp-1.0.11-1.i586.rpm ocfs-tools-1.0.10-1.i386.rpm ocfs-support-1.0.10-1.i386.rpm 1/ I have configured OCFS and a shared file system /opt/oracle/oradata 2/ I have created a raw device for use as quorum

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

I successfully have OCFS running in a two-node RAC environment using RHAS 3 (2.4.21-4.EL) using Qlogic 2310 cards. IO performance, however, was terrible with the combination of OCFS and the Qlogic cards. After extensive testing, OCFS did fine on its own, as did the fibre cards. Put the two together, and everything literally ran twice as slow. Support at Qlogic pointed me to

Hello, I want to use ocfs for a 10g RAC installation on a 2 node cluster, consisting of 1 Athlon and 1 Pentium machine with Firewire storage. OS is RHAS 3. Since I need to build my own binary Athlon rpm's, I downloaded ocfs-1.0.12.tar.gz ocfs-tools-1.0.10.tar.gz I was able to install both (./configure ; make - make install). When I try to load_ocfs I get lots of errors

Dear All... I need some information regarding OCFS performance in my Linux Box, herewith is my environment details : 1. We are using RHAS 2.1 with kernel 2.4.9-e.27 Enterprise 2.

Hi all, Sorry to break in, but I find this thread a bit interesting. Jeram: I'm not very familiar with HP storage and cannot find too much info on the EVA 6000 array. Is it related to the EVA 5000 somehow, or is it a NAS array? In any case, how is the array configured. If the algorithm for hartbeat is as described earlier (36 sector reads and one write per second (per host???)) then you

OCFS Experts, Sorry if the questions below are naive, or were answered before, but here it goes. I have a potential client who at the moment having problems installing 10g RAC on RHEL 3.0 (2.4.21-20). They using (rather planning to use) OCFS for everything, including CRS files (OCR, voting). Questions: 1) They use custom kernel (modified by their security people). Do we support OCFS on the

Sort of a followup... We've been running OCFS in sync mode for a little over a month now, and it has worked reasonably well. Performance is still a bit spotty, but we're told that the next kernel update for RHEL3 should improve the situation. We might eventually move to Polyserve's cluster filesystem for its multipathing capability and potentially better performance, but at least we

Dear Experts, One of our client wants to use OCFS for their 9i RAC(2 node) on RHEL3 and also use GFS on the nodes. Would there be any issues using OCFS for Oracle 9i RAC and using GFS for failing over things like print services on the same node? Has this been tested? I know these are competing products and OCFS 2.0is not an option now for the client. They need GFS for their custom apps. Any ideas

Can I run OCFS on Windows? We have OCFS running on RHAS 2.1 and have some customers asking about clustering on windows servers instead of linux. Are there some docs I can refer to?

Hi all Just need some ideas, is there any consideration if I collaborate OCFS + RHAS2.1 + RHAS 3.0 ( with 64bit Processor) in a RAC environment with 10 nodes. TIA Jeram

Hi all, I trying install OCFS in Red Hat AS 2.1, with Kernel 2.4.9-e.27, updated by RedHat-Network Service. When i compile the source code for version ocfs-1.0.9 , ( configure, make and make install) , and then i execute "depmod -a", i have the next output: depmod: *** Unresolved symbols in /lib/modules/2.4.9-e.27/kernel/drivers/addon/ocfs/ocfs.o If i try insert module with

Hi, is it possible and safe to use more than one RAC-Cluster using OCFS in the same LAN? I'm considering to following setup: a 2-node production and a 2-node test system, the production data is stored in an EMC Symmetrix and for the test-system the production data is copied once to a BCV disk internally. This will give me an new independant copy of the production disk with the same contents,

Hi, Irecently setup a Oracle 10g RAC test environment with two HP/Compaq DL380s and a shared disk array. The array is presented as a single 136GB disk. The systems are running RedHat AS 3.0 Update 4.

Oh yeah - easy way to check, Randy: Next time your node hangs, get on the OTHER NODE and go into each directory where files are being opened (datafiles, archivelogs, controlefiles, redo logs, etc) and delete a file (you can create one first then delete it). If this causes the hung node to recover then you're having the same problem I was having. Jeremy >>> "Jeremy

Hello again. I am setting up a new pair of servers to run RAC. They're connected via fibre-channel to a hardware RAID array, and both are able to see the exposed LUNs. When I create an OCFS filesystem on one node with mkfs.ocfs, I can mount it. When I try to mount from the other node, however, it fails. After that, the filesystem is left in a state where neither node can mount it. The
