Many people reported problems with RAC @ SLES10. I saw certification but I
never had a serious reasons to trust it. Absens of the document on Novell
page means _we did not tried it so no one used it yet_. Oracle certification
shows only _Oracle tested it in some unknown configuration and we believe
that it do work_ (don't mean that it really works or can be installed - we
had many opposite cases in the past; the best one was Oracle 10.1.0.3 RAC
which can't be installed onto linux x86_64 without interim patch but was
well certified by Oracle anyway).
I need to install development RAC next week (on x86_64) so I can try to go
thru it with SLES10 and make a document (through I am not sure yet - I don't
want to go thru all this headache with SLES10 again, after 3 unsuccesfull
attempts to use it in test systems). What should we do with orarun? (I used
old orarun modified heavily for RAC, but if orarun @ SLES10 supports it I
can try it).
What's about SLES10 propblems - of course, Oracle have relation to some of
them. DataGuard error looks as something wrong with Async IO on network
sockets. NFS error - no one promised that Oracle will work on Linux NFS.
But - both cases works on SLES9 SP3 and/or UL4.4 without a single glitch, so
it is Linux problem even if it have anything with Oracle.
Bad thing is not in this problems. They are natural for the new system. Bad
thing is in _enfocring system replacment before it is production-grade
quality_. In no way SLES10 was production grade quality, and it creates a
very bad PR for the SLES10 at whole. If we compare with RHEL5, we will see
much longer BETA period for RHEL, resulting in 2 sungnificant benefits:
- RHEL4 went much futher vs SLES9 because it was not _frozen_ on earlier
stages;
- RHEL5 quality is better vs SLES10 quality (comparing release-0 to
release-0) because of much wider beta programm.
SLES10 SP1 - yes, with all existing problems (as I saw, iSCSI was not
adjusted with other services, for example, and is not documented yet)
it looks as production-ready. But not sles10 release.

Correction: 10gR2 (RAC)/SLES10 is Oracle certified and works without any
issue. Document is not provided due to unique complexity of RAC setup.

This could be a bug in Oracle Data Gurad product.
Thanks,
