Yep – the problem was resolved by upgrading the Oracle client on the SqlServer machine.
It now maps Oracle numeric to sqlserver decimal as it should

Have you tried to run the same query by using the T-SQL OPENQUERY funcion ?
(i.e. select * from OPENQUERY(oraprod,’select * from sa.entities where pid = 9009460))

does it give you the same error ?

The problem was that the provider needs to be set to ‘allow inprocess’
This is just the reverse of what the MS web site claims.

My problem now is that a query such as:
SELECT * FROM oraprod..SA.ENTITIES WHERE PID = 9009460

Where oraprod is the linked server and pid is defined as numeric(10,0) in oracle, returns this error:

Msg 9803, Level 16, State 1, Line 1
Invalid data for type “numeric”.

How do I get the number to match what is expected by oracle?

Also check that your sqlnet.ora file does NOT have the parameter:
SQLNET.AUTHENTICATION_SERVICES=(NTS)
if it does, comment that line out.
