FW: Observations
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

OCFS Database too slow
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

i-node showing 100 % used whereas the partitionsare empty
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

E-Business 11i.9 and RAC 9.2.0.3
Hi, I am currently involved in a project with E-Business 11i.9. For the production enviroment, ct. wants to implement Load Balance and Fail Over - both middle tier and database tier, the last with RAC. As E11i creates lots of tablespaces, the best way seems to be OCFS. We installed & configured OCFS partitions. The next step was to install E11i multi tier, single instance - already

ORA-01207 after SAN maintenance
We had a situation over the weekend with our production database that we can't figure out, hoping someone can shed some light.

We shut down the database for san

H(U): A few OCFS questions
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

From OCFS to tape via tar (and back again)
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

data volume option, is it present in current version of ocfs2

ocfs seek-performance
hi list, i have a little problem with 2-node RAC using OCFS. the application running on this cluster does heavily index-based accesses. the data volumes are SAN volumes connected by fibrechannel. the throughput does not exceed 10mb/s, average is 7-8 mb/s. i've used 'iostat -x' and got rkB/s=8000 while %util=100% (device was saturated) from kernel's POV. i did some

ocfs performance
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

cp --o_direct
Another question. When my database is running, I do [oracle@LNCSTRTLDB03 LPTE3]$ cp --o_direct xdb01.dbf /tmp cp: cannot open `xdb01.dbf' for reading: Permission denied [oracle@LNCSTRTLDB03 LPTE3]$ When the database is shudown it works. Is this normal for ocfs because with any other filesystem I can just copy a file at any time (Its only a testing, I know I cant copy datafiles and have

OCFS Hang
Greetings, Having read about the previous OSFS hangs, I think this one that we are seeing is different, but I'm not sure if this is caused by OCFS or the Linux OS. We are running OCFS Version 1.09 with Linux AS 3.0/9i RAC. We have a 2 node Intel Cluster (Node 1 and Node 2). This morning the DBA tried to do an "ls" command on /u06/oradata/database

Fwd: RE: OCFS Hang
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

Disappointing Performance Using 9i RAC with OCFS on Linux
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

Rsync with OCFS (RAC)
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

[BUG] node 0 hangs until disk unmounted on node 1
I'm currently part of a project implementing Oracle eBusiness Suite 11i on RAC. We're using a two-node cluster with shared storage, both nodes are configured identical. Kernel is 2.4.9-e.27enterprise and ocfs is 1.0.9-11. I have checked and the shared storage can be accessed directly without any problems from both nodes (/dev/sdx). Curious if anyone has any suggestions or comments
