The TNSPING utility can be used to test an Oracle Service Name. To use it:

1.Open a Command Prompt (click Start, click Run, type cmd, and then click OK).

2.Type tnsping <service name> (for Oracle 7.3 or Oracle 8i and later) or tnsping80 <service name> (for Oracle 8.0), and then press enter.

The TNS Ping Utility will result in an "OK" or a "Connect failed" message. [...]
This was basically the first result searching for "oracle test connection command line" btw. Sauce
