similar to: Rsync with OCFS (RAC)

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

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

Hi to all: I''m trying to build an Oracle Rac10gR2 under 2 xenitized RedHat 4 nodes ( The host domain is debian 3.1 ) Well, all goes well until time to mount ocfs2. For Rac10gR2 I need to mount ocfs2 partitions with the datavolume option, but latests versions of ocfs2 doesn''t comes with this option ( you can enable the O_DIRECT feature directly in the init.ora file, with the

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

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

Wim, Below are two problems I found in testing the newly released ocfs version. Just for your information. Gr, Robert. - Copying of multiple files gives errors [oracle@prac01 test]$ cp --o_direct -R ./a2/* ./backup/a2/. cp: writing `./backup/a2/./ccdata.dbf.bck': Invalid argument cp: writing `./backup/a2/./ccindex.dbf': Invalid argument cp: writing `./backup/a2/./control02.ctl':

Is the order important when installing ocfs2 and Oracle RAC? If you have an existing RAC installation and you want to use ocfs2 for shared files but not for the OCR or Voting Disks, do you need to reinstall the Oracle Clusterware after installing OCFS2?

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

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, 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 We currently use rsync for various jobs at our company. We are now looking at using it to create an offsite synchonised copy of an Oracle 10g RAC archive logs area. The source area is on Oracle OCFS filesystem. 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

Guys, posted this last week and had no response so far. Just posting again in case anyone missed it. I really could do with knowing as it's delaying the rollout of a new project I'm working on.
