I am running 10g R1 on SLES 9 - x64 on a dual machine.

Everytime after the machine continuously run for a few months I need to
shutdown the machine to do some maintenance work. I notice that on both
occasion (I have only done it twice) the listener shutdown process with
orarun scripts hang. After about 15-20 min, I had no choice but to go
with the off button. ( I can't login with other console anymore) and
ctl-alt-sysrq don't seems to work ( is it compiled in with the default
kernel?)

Has anyone got a similar problem?

Thanks.

Hongyee,

I am running 10g R1 on SLES 9 - x64 on a dual

ctl-alt-sysrq don't seems to work ( is it compiled in with the

Next time set "echo '1' >/proc/sys/kernel/sysrq" to enable sysrq before
rebooting to see what is the problem.

Daniel,

Im reading documentation about ocfs and triying to install it but i
cant
find an answer the most simple question, can i use ocfs i a normal hd
or do
i need shared disk that the 2 or 3 nodes can see(shared scsi, SAN,
etc.)?

You can install CFS2 on regular hard disk but make more sense with
shared disks in RAC env.

I guess you could use CFS2 on a single machine, but what would be the point?
You should use a regular file sytem.

hy thnx for the reply,

Well in one computer is uselless to install ocfs but my question is , if you
install ocfs2 in a normal hard disk in one computer does it sincronize with
the rest of the nodes using the net? or if u use a single normal hd disk its
imposible for other machines to see whats in the ocfs partiton?.

Thnx

CFS2 is not intented to work that way (through the network). See DRBD for
that. http://www.drbd.org/

you could look into iSCSI (SCSI over IP) if you want to make a cluster for
experimenting with RAC, without an expensive shared storage.

But this won't be good for production, because of performance issues.

Yes, you do need such a storage. However, for testing you can simulate
it using iSCSI.

You can also use NFS its rubish but for testing its ok.

You _cannot_ use CFS2 on top of NFS.
