An OPS & tnsnames question

Dear list !
I've got an OPS database named OPS with 2 instances OPS1 and OPS2 . I want the users to connect to OPS1 and ONLY if it is down , to connect to OPS2.
It's Oracle 8.0.5.1 on NT4.

I put the following lines in clients' tnsnames.ora file :

OPS.world = (DESCRIPTION_LIST =

        (DESCRIPTION = 

(ADDRESS = (PROTOCOL = tcp) (HOST = DB1) (PORT = 1526))
(CONNECT_DATA = (SID = OPS1))
) (DESCRIPTION =
(ADDRESS = (PROTOCOL = tcp) (HOST = DB2) (PORT = 1526))
(CONNECT_DATA = (SID = OPS2))
)

)

This works perfectly fine except for the case when OPS1 instance is down , but the listener is up.
Then clients try to connect to OPS1 and fail - "Oracle not available" . When i bring the listener on OPS1 host down - everybody perfectly connect to OPS2. Is there a solution ?
Thanks a lot in advance !

DBAndrey
