Hi, we have a 2 node / 3 node RAC installation with OCFS. We have the following observations. 1. TIME STAMP Issue We have noticed that the time stamp which is shown on the datafiles doesnt remain the same even after a shutdown normal /shutdown immediate i.e If I shutdown all RAC instances ( A , B , C) using shutdown normal / immediate, the timestamp on the datafiles are not the same. Even

Hi All, we are using Red Hat 2.1 Kernel e38 along with MSA 1000. ocfs version being used is $ rpm -qa | grep ocfs ocfs-tools-1.0.10-1 ocfs-2.4.9-e-enterprise-1.0.12-1 ocfs-support-1.0.10-1 Database Version is 9.2.0.5 However we find that the performance of the database on OCFS is too slow. even a select count(1) from all_tables takes like a while to complete. We initially assumed RAC is

Hi Sunil, I had filed a bug and saw your response stating that it would be fixed in version 14. In the meanwhile , what we want to know is whether this bug is a minor bug and can be ignored for now. Does reporting 100% inodes cause any problem for the OCFS file system or can we ignore this bug and go into production. Also can you tell us by when version 14 would be released. R'gds

Hi Sunil, I'm looking into this thread now. Does this mean we cannot use FTP option to copy OCFS files to ext3? If so, is there any ftp version available for OCFS, similar to cp --o_direct? Also, is there any version of sync available for OCFS (in normal FS, sync does a refresh of FS from kernel cache so that the FS is consistent). By this can we say that the FS shard by both nodes is

Hi All Does anyone have information on OCFS compatibility with Legato. i.e Can we use Letato to backup directly from OCFS Volumes. Also does OCFS work with BCV.

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

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

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

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

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

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, 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
