Connection help

[blmack44]

I can make a connection to a db on a remote machine. If I take away my local tnsnames.ora file, it still makes a connection to that database by typing in the service name.

How does PL/SQL developer know how to connect without any information from tnsnames.ora?

(Connecting from Windows via the OCI.dll from oracle instant client).

Thanks,

I can only assume that:

1. You have multiple Oracle Homes, and have removed the wrong tnsnames.ora file.

2. You have a TNS_ADMIN entry and have removed a tnsnames.ora file that is not used.

In any case, if you go to Help > About and press the Info (I) button, you will see the tnsnames file that is actually used.
