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

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

Hi, I am trying to install Oracle 9i RAC on SLES 8 SP3 with a shared firewire disk.

Hi, I'm new to the list, so forgive me if I'm asking several naive questions that have been answered a dozen times before. I have RHAS with kernel version 2.4.9-e.10smp, running ocfs-support-1.0-2, ocfs-tools-1.0-2, ocfs-2.4.9-e.10-smp-1.0-2. I have Oracle 9iR2 RAC up and running on an IBM fiber channel architecture. I find it to be extremely slow compared to other stand alone

I'm attempting to build the inexpensive 10g RAC cluster as outlined in Jeffrey Hunter's paper "Build Your Own Oracle RAC 10g Clulster on Linux and FireWire". I've got the hardware working and everything is looking good up to the step where I need to download and install OCFS. I'm using WhiteBox Linux v. 4, which is RedHat AS 4 and based on 2.6 kernel. I did find an

Hello All We currently use rsync for various jobs at our company. We are now looking at using it to create an offsite synchronized copy of an Oracle 10g RAC archive logs area. The source area is on Oracle OCFS file system. The OCFS filesystem requires all reads/writes to be performed with the O_DIRECT option, thus bypassing cache. Oracle provide an updated coreutils package which includes the

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

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 all, I hope someone can give me some insight on this. I have finally gotten a RAC database up and running on the RedHat AS 2.1 Linux cluster using OCFS 1.0.9.4. My XP admin has given dual luns to the drives in which my database sits. So the question comes up how do I do this? Using software raid? on the host os'es: xpinfo -il Device File ALPA Tgt Lun Port CU:LDev

I've got my RAC cluster running pretty smoothly now (thanks again for all the help so far), but I only have single connections between the servers and the RAID array. The servers each have two Qlogic HBAs, and I'd like to find out if there's any reasonable way to implement multipathing. The platform is RHEL 3, and Red Hat's knowledgebase indicates that they strongly recommend

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

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

Hi all, hoping someone has some insight on this issue. I am working on a first install of RAC. I have installed OCFS 1.0.9.4 (upgraded from 1.0.8 before installing the rest of the oracle software) on a 3 node RedHat AS 2.1 cluster. The kernel is 2.4.9-e.25.enterprise. Oracle software installed 9.2.0.4. I fdisk'd the storage devices, mkfs.ocfs on the partitions, and mounted successfully on

We're using RMAN to back up our 9.2 RAC database to an OCFS v1 volume. We have an existing shell script that we use for copying files from disk to tape via tar, one file at a time. (Don't ask why. It's a legacy script. Long story.) We're tweaking this script to use --o_direct when tarring the file to tape and that seems to be working fine: # tape device is /dev/nst0 $ tar
