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 OCFS Gurus... I have 2 questions for OCFS ver 1.0.10.1 1. What is the Maximum mount point suggested if we are using OCFS ? 2. Is there any method to tune the OCFS to booster the IO performance? Awaiting ur responses... Thanks in Advance... Rgds/Jeram

Hi all, Sorry to break in, but I find this thread a bit interesting. Jeram: I'm not very familiar with HP storage and cannot find too much info on the EVA 6000 array. Is it related to the EVA 5000 somehow, or is it a NAS array? In any case, how is the array configured. If the algorithm for hartbeat is as described earlier (36 sector reads and one write per second (per host???)) then you

Hi All, Scenario: I'm trying to install 9i rac on a 2 node cluster on OCFS2 OS: Oracle enterprise linux To my understanding, OCFS2 supports shared home installs which to my knowledge is not only can i have datafile and control files but also clustermanager files and binaries (pretty much everything: no files or executables need to kept local to any nodes). I have one single shared file for

Hi All, we are using Red Hat 2.1 Kernel e38 along with MSA 1000. ocfs version being used is $ rpm -qa | grep ocfs ocfs-tools-1.0.10-1 ocfs-2.4.9-e-enterprise-1.0.12-1 ocfs-support-1.0.10-1 Database Version is 9.2.0.5 However we find that the performance of the database on OCFS is too slow. even a select count(1) from all_tables takes like a while to complete. We initially assumed RAC is

Hi all... I have a strange problem. 2 of my mount points already use 7% of space, even when I check the directory is empty. When I re-format it, it release the space for a while, after 1 or 2 days, the space is used again for 7% - 10 %. What could be the reason? I am using RHAS 2.1 Enterprise Kernel 2.1 and OCFS release 1.0.9-6 Thanks Jeram

Hi all Just need some ideas, is there any consideration if I collaborate OCFS + RHAS2.1 + RHAS 3.0 ( with 64bit Processor) in a RAC environment with 10 nodes. TIA Jeram

We are running Linux AS 2.1 .27 enterprise on an EMC CX400 SAN with ocfs version enterprise 1.0.9-12. After formatting the partitions the response from the filesystem is very slow during either read or writes. Even worse, while we can create a directory, we are unable to delete the directory after it has been created. Every time any directory is attempted to be removed with rmdir we get a

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

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 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

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 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
