Oracle 10g on FreeBSD

[Michael Vince-3]

Hi All,

I have been contemplating buying a high end server and running a lot of
stuff on it in jails including Oracle 10g under linux emu.
I would be using Amd64 as the server would have 8gigs of ram or more.
The idea would be that the Oracle 10g would just be a slave server to a
dedicated 10g server on linux and would act as a emergency backup to the
real server and consolidate some rack space at the same time, and
hopefully could do some lighter amount work such as read queries.

Anyone gone down this path with 10g? I was thinking that since the linux
emulation has been getting a fair bit of work lately it would be good to
try and really utilize it.

Cheers,
Mike

I think you need linux_aio which is only in p4 and awaits final review or something.
you also need correct TLS (present in cvs) and corrrect futexes (present in my head,
will appear in cvs in a few days)

with this I think you should be able to test the oracle :)

You will not be able to use this much of RAM in linux programs. Only  
32bit linux programs run on amd64 so far.

Bye,
Alexander.

The idea behind using Amd64 FreeBSD is just to be able to use a lot of
ram for the other regular jails etc.
The Linux Oracle would be the 32bit version, Oracle unlike MySQL appears
to slice it self up into a lot of smaller sized processes a lot like
Postgres.
Do you think I would have any issues using it this way?

Thanks

No, but linux-aio may be needed for Oracle (not available in -current yet).

Alexander.
