I have a question regarding Validation Query:

The CF  9  online help says this about the Validation Query:
Called when a connection from the pool is reused. This can slow query response 
time because an additional query is generated. You should specify this just 
before restarting the database to verify all connections, but remove the 
validation query after restarting the database to avoid any performance loss.
If you are pointing to an Oracle RAC Cluster containing 2 nodes and want to 
ensure that the RAC node the connection is currently bound to is viable doesn't 
it make sense to leave the validation query in place?  (select 1 from dual;) 
regardless  of the small performance hit I would rather prefer that my 
connection is viable.

What is everyone's opinion on this?

Thank you in advance.
