similar to: Can OCFS and GFS co-exist on the same RHEL 3 RAC node??

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

Hi, I am trying to install Oracle 9i RAC on SLES 8 SP3 with a shared firewire disk. I am using the following OCFS: OCFS Release 1.0.11-1 for suse sp3 2.4.21-138 smp kernel ocfs-2.4.21-138-smp-1.0.11-1.i586.rpm ocfs-tools-1.0.10-1.i386.rpm ocfs-support-1.0.10-1.i386.rpm 1/ I have configured OCFS and a shared file system /opt/oracle/oradata 2/ I have created a raw device for use as quorum

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

Hi... I have a strange problem with my Private NIC Channel, here is my environment details : 1. RHAS 2.1 with kernel 2.4.9-e.27 Enterprise 2. OCFS version : 2.4.9-e-enterprise-1.0.9-6 3.

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

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

Hello All, I am currently running ocfs 1.0.9-9 with kernel 2.4.21-4.Elhugemem (RHEL3) and 9i RAC (9.2.0.4).

I know this isn't entirely OCFS related, but out of curiosity, but what experience have you had running RAC on RedHat or SuSE? I know Oracle supports both, but is one a better choice than the other? Seems to me like Oracle has been working more with RedHat. Does anyone know what Oracle mostly uses internally? What distro do you guys develop on? Would there be any drawbacks for choosing to

Hello, I've successfully configured RAC on Redhat AS, with external firewire + ocfs. The whole process was done without any errors and have created the database. (Thanks to Wim Coekaerts useful article). But now, how do I actually use it? If I have a client making a connection, to which node do I connect? Are there also any recommended procedures to test RAC's capabilities? Thanks.

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

I am starting to see a few issues with OCFS and 9.2.0.3 RAC on redHat Linux AS 2.1. Wondering if there is anyone out there experiencing similar issues... a few pointers to the issues.. 1. OCFS read/write performance is way lower than a read/write to a raw device.. i can give you some comparison numbers.. 2. Writes to shared disk with ocfs would get locked up by one server.. it doesnt have to

Hello again. Our production cluster has begun experiencing some vicious slowdowns that may (or may not) be related to the filesystems. When the problem occurs, the load average on the servers jumps up to 30 or higher. Usually one node will climb while the other drops, then they will switch places a few minutes later. At one point, we had one node's load average up over 300. Our site

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
