OPS$ and database services

Question

All,
I'm on 10.1 Solaris with an "OPS$" (externally identified) user, through which all application logins (batch loads) are made. I also have a range of database services and would like to connect this user to a specific service based on the batch type (e.g. connections for the "london" batch would be made to the "london" service and so on).
Connections are made via the Perl DBI but I'm also trying to test via sqlplus, which is the easiest place to start.
The SQL*plus documentation states that the connection identifier cannot be used with an OPS$ user:
"You cannot enter a connect_identifier if you use a default logon."
That seems pretty final to me.
But has anyone got any ideas or experience of how I might connect to a service with an OPS$ user? Or even register with a service once I'm logged in, for example?
Thanks

Why? What problem are you solving by doing it this way?

Not sure how you can. To connect as an OPS$ user requires a local IPC connection. You cannot use a TNS alias or set it via TWO_TASK - as then the connection would be via TCP to the listener and how can it use o/s authentication as you could be coming from anywhere across the network.
Or am I missing something here?
