wine users - Apr 2005 - Oracle error "Ora-01012: not logged on" on BDE under wine

Hello, folks.

I am having a problem to connect the Oracle using an alias in BDE under WINE. I
did
install the Oracle Client and the BDE under WINE and both working perfectly.
However, when I create an Oracle alias in BDE, I cannot to test the connection,
obtaining this error:

"ORA-01012: not logged on"

Any suggestion ???

Thanks, Robson Sampaio.
