Hi guys,
i am not quite sure where i should have mentioned the vendor support topic -
support can be as good or as bad as with any OS vendor ;-)
The only thing that i have said is that OEL is a very good choice as it is
already pre-configured for RDBMS (e.g. I/O scheduler or memory options like
disabled transparent huge pages, etc.), if Jeff's company is going to move to
Linux and they are not very familiar with it yet.
In addition if his company is going to purchase support (ULN), they get
additional benefits with OEL (only) like:
- DTrace (not as great as DTrace on Solaris, but it's ok)
- Ksplice (with Premier Support only afaik)
- XFS file system support

Full disclaimer... I'm Ryan's colleague, and opened the 6+ month train wreck
of a production-data-corruption SR (with reproducible test case
provided on day one) which he alluded to. Fun times.

I understand this works great in theory, however as a full stack Oracle
customer (from the hardware up) I have to say it doesn't work that way
in practice.
We recently had an RDBMS bug that was exposed through GoldenGate
functionality. The back and forth between both business units and Oracle
Support was maddening.
After fingers were pointed at each BU for months we tried getting our
reps involved, however they only 'had pull' with respect to their
division and were of little external assistance. That resulted in a lot of
'we'll get back with you' and finger pointing.
Nothing would please me more to agree with you, but I know too many
people with similar stories.
