When using tnsping, can I specify a port number along with the SID?

问题

I use Bitvise Tunnelier to connect to a series of Oracle databases using SQL Developer; the connection is made to localhost and a specific port number, and this works fine. I'd like to connect through other means (e.g., .NET), and I'm troubleshooting with tnsping.

Is there any way to run tnsping with a port number as well as the SID? I've tried:

tnsping DatabaseSIDName:9001
tnsping DatabaseSIDName;9001
tnsping DatabaseSIDName,9001

All give "TNS-03505: Failed to resolve name".

When you use tnsping, it will source some Oracle .ora files to determine what DBs it knows about. You should see something like:

$ tnsping myDB

You can create your own tnsnames.ora file and add that to your TNS_ADMIN environment variable to add a new DB, port, SID, etc. A full example looks like:

ORA11 =
 (DESCRIPTION = 
  (ADDRESS_LIST =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 9001))
  )
 (CONNECT_DATA =
  (SERVICE_NAME = DatabaseSIDName)
 )
)

Just export TNS_ADMIN=<path to folder containing new tnsnames.ora file> and attempt the ping again. Here are some references:

EDIT

And per your original example/follow up comment, the simplest might be:

$ORACLE_HOME/bin/tnsping <hostname>:<port>/<sid>

There are an abundance of other options, like EZConnect and sqlplus that will test the same functionality.
