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

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

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 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.

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 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

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':

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

I am still having this weird problem with nodes hanging while I'm running OCFS. I'm using OCFS 1.0.9-12 and RHAS 2.1 I've been working on tracking it down and here's what I've got so far: 1. I create a file from node 0. This succeeds; I can /bin/cat the file, append, edit, or whatever. 2. From node 1, I do an operation that accesses the DirNode (e.g. /bin/ls) 3. Node 0

Hello all, I'm using OCFS version 1.0.15-PROD5 on RHAS3 Update 4. My RMAN script for delete obsolete fails. Debugging problem I've found that is not able to remove a file. Seems that this file is in use and any operation is not possible. Reading metalink I've found some docs about problem with cp/mv/dd/tar on files under OCFS and suggestion is always to use option --o_direct. In my

I created an account on the Forums this morning, but I got an error saying they were having a problem sending e-mail. I sent a message to the webmaster and no response either. So I can't post to the forum until my account is activated. Are the forums new? By the amount of traffic on the list, this must be where most people resolved their problems.

Hi, We are currently rolling over our SAN (FC4700 to CX700) and have now reached the data migration stage. I need to move the data files on my current /u01 ocfs file system (on FC4700) to a new ocfs file system (on CX700) which I want to keep as the same /u01 mount point on the hosts. With a normal file system I would just mount the new file system to a temporary mount point, copy the data,

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.
