TNS listener not working for client tools ("no listener"), but Sql Plus command window is ok

I can log on to sql plus successfully from the command line, but when attempting to connect with various client tools, I keep getting "No listener".

But I can connect via Sql Plus in command window

The Listener is started in services, and here is the status (points to, Orcl shows ready)

so it's registered ok.

- this is a follow-on from How to connect to PC #1 (running Oracle) from PC #2 (running Oracle client), where I was trying to connect from PC #2  to PC #1. The solution was to specify the local IP address ( in the tnsnames file and in listener.ora, and to register. All was good, thus allowing me to connect from remote PC's

- just today I set up Oracle client on two different PC's, and I can connect via Sql Plus to scott/tiger@orcl

- so in circling back to regression testing on PC #1, something's wrong with the Listener when trying to connect with client tools :-(. Although I can connect from Sql Developer . . .

Also, I checked my PATH and it's good.

Check for multiple oracle homes.

Oracle product installs can create new ORACLE_HOME's.  Each one of these needs it's own tnsnames.ora file.

In the first example using sqlplusw (Windows based sqlplus), what ORACLE_HOME did that run from?  Does that home have correct entries in the tnsnames.ora file?

>>But I can connect via Sql Plus in command window

That is a DIRECT connection, not a 'remote' connection.

That is your tnsnames.ora file from 'which' ORACLE_HOME?

My guess is you have several Oracle products installed in several ORACLE_HOMES?

slightwv, thanks . . .

>>Check for multiple oracle homes.
-- bingo ! I didn't change the tnsnames in my "DevSuiteHome_1" location. Now I can connect, yea . . .

>>But I can connect via Sql Plus in command window. That is a DIRECT connection, not a 'remote' connection.
-- are the client applications considered "remote"

but I got it :-)

Oracle has two types of connections:
bequeath and networked.

A bequeath is a direct pipe into the database and no networking is involved.

You can do either from the database server itself.  You cannot do a bequeath connection from a remote machine.
