Oracle RAC init.ora parameters

[Eddy99]

What would you recommend for the following parameters in a 2 node RAC database, should the locations to which they point be on shared storage or not ?
We are using OCFS Version 1 and a 10.1.0.4 database.
I am in the process of creating my first RAC database and I am a little confused.

The parameters in question are:-

background_dump_dest
core_dump_dest
user_dump_dest

Should each instance have its own location for each of the above as I would view them as being instance specific as opposed tied to the database.

Reading notes on Metalink it would appear that they have only a single location that is database wide as opposed to instance specific.

Any advice or help would be much appreciated,
Cheers,

if you are using ocfs you cant put alert logs, trace files on them - its not posix compliant (yet)

we keep those directories local to each server, i think it provides a 'cleaner' solution as you can see what instance is producing what easier.

What i think I realised last night whilst musing this over in bed last is that the $ORACLE_BASE/admin//bdump directories are infact using the db_name and not the instance_name - therefore as there will only be one locally mounted disk of the same name visible on each node this is where my confusion arose i believe. Hopefully the Unix guys will get my boxes prepared and i can have a go at installing :-)
