Hi, all. My name is Kenichiro Ochi, in Oracle Japan Support. Customer examines upgrading OCFS from 1.0.9-12 to 1.0.14-1. And customer asked us a question about the way of downgrading to 1.0.9-12. (customer presumes a case in case after the upgrade.) We tested the following... 0.After the upgrade 1.umount OCFS volume on all nodes 2.uninstall rpm (V1.0.14-1) # rpm -e ocfs-tools-1.0.10-1 # rpm

Hi, we have installed ocfs2 on Rhat 4. It is being used as a general clustered file system. There are no oracle binaries or datafiles on the ocfs volume. So no need for RMAN or oarcle agents etc etc. The customer would like to backup the volume using arcserve. However CA are saying that they cannot backup from an ocfs volume. Has anyone out there got any words of wisdom about backing up

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

Sort of a followup... We've been running OCFS in sync mode for a little over a month now, and it has worked reasonably well. Performance is still a bit spotty, but we're told that the next kernel update for RHEL3 should improve the situation. We might eventually move to Polyserve's cluster filesystem for its multipathing capability and potentially better performance, but at least we

Can I create an OCFS 2 filesystem over a ASM volume to store datafiles? Thanks! Roger---

an ocfs-volume was nearly full (only 800MB free). i deleted some datafiles to free space: $ df -h .

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

I have noticed that OCFS is not updating the filesystem space stats when datafiles are reduced in size: is this Bug 62, and if so is there an expected fix date? ocfs-2.4.9-e-enterprise-1.0.11-1 ocfs-support-1.0.10-1 ocfs-tools-1.0.10-1 Linux sgl43d-122 2.4.9-e.35enterprise #1 SMP Wed Jan 7 15:11:27 EST 2004 i686 unknown bytes name 2097152000 /data/oracle/QSG40/u01/dtr_med_i_02.dbf /dev/sdc1

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

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

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, well i mounted the OCFS drive over nfs, but it seems to have problems with it, because the NFS does not detect changes (if I add or delete files) the nfs shares still shows the old status. If i delete a file on the OCFS volume, and i am doing a "ls" on one of the nfs clients, it says for every file which was on the ocfs, "no such file or directory". Did I miss

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

Last week when I tried to delete datafiles from the same directory, it did delete datafiles but did not release (reclaim) all space. It still showed that 20G of

Hello, I have been searching for it but could not find anything on Oracle different servers. Maybe someone here will be able to answer this question : Are CLOB and SYS.XML data type supported by OCFS? We need to migrate a 9.2.0.4 Windows Database having these data types to a 9.2.0.4 Linux Real Application Cluster with OCFS. This could cause an issue. Thanks in advance Philippe

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,

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

I've tried several times to resize one of my ocfs volumes[see emcpowere1 below] I'm on the latest [prod] version of ocfs/ocfs-tools as of 3pm EST on 18JUL04. Per instructions... Take down db, unmount all ocfs drives, use ' tuneocfs -F -S 100G /dev/emcpowere1 ' Supposedly this should work, but I get get.... The size specified, 100G, is larger than the device size, 59G. Aborting.
