I would comment the first three entries in your client sqlnet.ora (or go
without the client sqlnet.ora at all) and modify the tnsnames.ora entry like
this:

OPOSSUM =
(description =
  (address = (protocol = tcp) (host = localhost) (port = 25000))
  (connect_data =
   (SERVICE_NAME = OPOSSUM)
  )
)

or

OPOSSUM =
(description =
  (address = (protocol = tcp) (host = localhost) (port = 25000))
  (connect_data =
   (SERVICE_NAME = OPOSSUM)
   (global_name = OPOSSUM.WORLD)
  )
)

If you can try not to rely on the domain even server side.
To have a WORLD to main is pretty useless for you (personal opinion here).
