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

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, 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 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, 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, 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

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

Here's a bit of a strange one. I hunted through the ocfs-users archives, but didn't see any mention of this, so here goes... Using coreutils 4.5.3-27 on RHAS 3, the utilities perform as expected against non-OCFS volumes: $ rpm -q coreutils coreutils-4.5.3-27 # cat a 3 line test file. Works as expected $ cat /var/tmp/file line1 line2 line3 # copy that file. Works as expected $ cp

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 all... Currently I am having 5 RAC nodes with Configurations as below : 1. HW = DL580 32 Bit Processor 2. OS = RHAS 2.1 3. OCFS= Latest Version 4. RAC= Oracle9i 9.2.0.5 (32 Bit) Now I am planning to add 2 more Rac Nodes in the existing RAC: 1. HW=Itanium 64 bit processor 2. OS=RHAS 3.0 3. OCFS=Latest Version 4. RAC=Oracle9i 9.2.0.5 (32 bit) Can I

Hi Bharat/Philip, I haven't tested it yet. My systems are running RHAS 2.1. I'll come back to let you now the outcome.

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 All, Is there any one know if OCFS2 will be certified on RedHat AS3 or 2.1? On http://oss.oracle.com I see OCFS2 Beta is available for RHAS 4 only.

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

We are running 2-node RAC on RedHat Linux-86 (32-bit) the following was done on (4/10/2005) 1. upgrade OS to update 4 (kernel-smp-2.4.21-27.0.2.EL) 2. upgrade OCFS 1.0.12 to ocfs-2.4.21-EL-smp-1.0.14-1 3. upgrade from 9.2.0.5 to 9.2.0.6 (IN 2-Node RAC) 4. change defualt temporary tablespace to regular one (Rac bug fix) 5.
