Hi Russ,
yes you do have a situation there. I honestly would not be able to
contribute here as I do not know the background. I can't blame Suse
either as file system is connected with the base kernel and my guess is
that you would have hit the same issue had you been running any other
flavor (unless this is not a file system issue). Linux flavors support
file systems like - ext2, ext3, raiserfs etc. that are commonly used by
all. Besides SAN/NAS may be configured on a different file system that
Linux talks to. This will need a deeper investigation to identify the
problem. Do update us if you do find more on this, it will be good to
learn from your experience. In
case you do have an Oracle SR or Linux support details on this matter,
do forward it to me if it is OK.
I have encountered somewhat similar situation in the past. The prime
thing is to identify whether it is software or hardware related. In my
case, one Red Hat issue was due to an older file system type and a Sun
system issue was genuinely a hard disk block corruption. In both cases,
making appropriate changes (either software or hardware) resolved it.
If you encounter similar situation again, I would be curious enough. As
this is not a Linux list, you could privately send me more details. I
can't imagine if changing to another flavor would help but educate me
if you find something different.
Thanks!

Hi,
I'm the friend. I just subscribed so not sure if this will post
to oracle-l list or not. We have been running SLES-9 for a couple
years and recently built 4 servers with SLES-10. We are migrating from
Solaris to Linux. Overall, SuSE Linux has done fine. However, we've
had two anomalys occur, once on SLES-9 and once on SLES-10, in the past
4 months that have us concerned. With no warning and with no errors
prior, a handful of files or a subdirectory becomes corrupt. The ls
command doesn't show the corrupted item(s) any longer, but something
like 'ls xyz*' produces an I/O error. Also, you cannot delete the
affected item but you can delete everything in the directory. This
occurred once with about 10 audit files ($ORACLE_HOME/rdbms/audit/) and
once with the Oracle timezone file
($ORACLE_HOME/rdbms/oracore/zoneinfo).
We are trying to determine if other flavors of Linux are more
stable, based on user feedback. What's your opinion?
Thanks

Hi
Kevin,
Implementing and administering
on Oracle enterprise Linux (also called "unbreakable") is as good as
any other flavor. I have tried it along with other flavors for about an
year now. Initially, there was lot of bad vibes on this flavor. Some
said it existed to erode the Red Hat Linux market by giving lower
prices for the same software. It was badly documented too. I have seen
things improving a lot and Oracle has a good grip on this subject.
Support is good.
Here is some more info that may be interesting to your friend. As a consultant, I have installed and deployed
Oracle (database, application server) applications on Red Hat Linux for
most of the last 6 years. Some time back, I decided to Look at Ubuntu
and Oracle Enterprise Linux to
increase my support on Linux flavors and give more options to clients.
Oracle Enterprise Linux is based on Red Hat Enterprise Linux and I
found no difference between the two. Oracle support is good and they
provide customized RPMs (or direct to appropriate site). Implementing
and running applications is equally good. But I have no issues with Red
Hat support either. To be honest, any flavor you take it is the same
base kernel being used. So the decision has to be more on comfort
levels, company standards and costing.
One concern raised by some clients was that it increases the dependency
on a single vendor (Oracle will provide OS, Database, runtime, AS and
even Virtualization). My take is that Oracle is designing new
technologies on Open Source Model and that the dependency is not on a
single vendor (except for commercial purposes) but on the huge
development community out there.
So the stand I have taken is- Let the clients decide. If they ask me
then I check with them if costing matters (though the differences are
insignificant for someone buying Oracle licenses). If it doesn't, then
as of this time I recommend Red Hat Linux. This is more a personal
choice as I am connected with the Fedora community (dev to Red Hat
production) and am aware of what is happening in the flavor. Ask your
friend to identify the possible scope (money, support cost, non-oracle
applications, vendor dependency, management stand, IT stand etc..) that
needs to be satisfied when looking for a flavor, it might help in
making a choice.
Thanks!

A friend of mine is considering Unbreakable in his organization and
wondered if I had heard of anybody using it in production. I personally
haven't but was wondering if anyone on this list was using it and what
they're feelings about it were? Have you used Oracle's support and how
was it?
Thanks,
Kevin Lidh
