Hi, Somehow, when running the database creation script, my machine hangs. I've used all the files from http://oss.oracle.com/~wcoekaer/firewire/ Using Oracle 9.0.2.1. Has anyone experienced the same? Any solutions? Thanks, Faisal

Hi again, It seems that I have a problem again. When I startup the database, it has an error: ORA-29701: cannot connect to Cluster Manager. 1. I have started the the cluster manager, and ps -ef shows that watchdog and and oracm is running. 2. I've looked into the cm.log, and it seems that both nodes have registered successfully. Sure could use some help. Thanks. Warm regards, Faisal

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 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

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

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 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 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

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

(Yep, it's me again) We've worked around some minor glitches and now have a pair of nodes happily sharing an OCFS volume. I was wondering, though, if it was possible to configure a second private IP address so that the nodes could communicate over more than one Gigabit Ethernet connection. Our RAC books and online docs make some vague references to multiple interconnects, but I have yet

Dear All... I need some information regarding OCFS performance in my Linux Box, herewith is my environment details : 1. We are using RHAS 2.1 with kernel 2.4.9-e.27 Enterprise 2. OCFS version : 2.4.9-e-enterprise-1.0.9-6 3. Oracle RDBMS : 9.2.0.4 RAC with 5 Nodes 4. Storage = EVA 6000 with 8 TB SIZE 5. We have 1 DiskGroup and 51 LUNs configured in EVA6000. My Question is : 1. It takes arround 15

Hi, I sent an email to Mark Fisheh of Oracle Corp. & posted this issue at OTN under Linux thread this morning. I hope that someone among you might have experienced this and can help. On that basis, I am sending this to you too. I am stuck & will really appreciate if you can shed some light on this. Thanks. Anjan

remember that even tho you have a filesystem etc it's always good to have seperate partitions for stuff. eg don't put all your redologs and mirrors on the same partition or don't put your archives on the same partition as data. this is not just for ocfs, but just .. common sense I think to split stuff up.

Hello again. I am setting up a new pair of servers to run RAC. They're connected via fibre-channel to a hardware RAID array, and both are able to see the exposed LUNs. When I create an OCFS filesystem on one node with mkfs.ocfs, I can mount it. When I try to mount from the other node, however, it fails. After that, the filesystem is left in a state where neither node can mount it. The

I'm preparing a pair of Red Hat Enterprise Linux 3 servers on which to test RAC. Currently they are running the 2.4.21-4.0.2 kernel. I saw that the 1.0.9-9 OCFS binaries are tied to the 4.0.1 kernel, and confirmed that myself. The 1.0.9-12 packages are dated a few days later and don't refer to a specific kernel version, so I assumed they would work with 4.0.2. However, when I try to
