RAC 10g2 SLES10: hangcheck-timer, asmlib, ocfs2 and heartbeat

Hi list,

the RAC installation docs I found on OTN or the docs from
"RAC for
Administrators" course at Oracle University, are for
RedHat 3.0 or
higher . They use the hangcheck-timer kernel module, which
is not part
of SLES 10. Is it really needed on SLES10 ?
The hangcheck-timer site
(http://oss.oracle.com/projects/hangcheck
-timer/dist/documentation/README)
says it was integrated in kernels 2.5. How can it be
configured ? The
vmware 2 node installation is more 'lazy' so I would like to
set higher
values for it.

Maybe this is not related to hangcheck-timer module:
the ocfs2 installation , when configuring O2CB driver also
asks about
kernel or userspace heartbeat method. Does that mean I have
to install
and configure the heartbeat system ? Do you have any clues
?

Maybe I should put 3 different entries in the list ? So
threads should
be more consistent?

Thanks in advance !

1) Docs are for both RHEL and SLES.
2) Try to use docs from http://www.suse.com/oracle
, they are specific for
SuSe.
3) hangcheck-timer is part of SLES10.
4) Oracle RAC configure it itself, you should not worry
about this module.

Thanks very much for your quick response.

 It seem that I tried to install oc2b driver on an unpatched
SLES. After
applying 450 MB of updates, the instalation didn't complain
about
hangcheck timer any more.
