Help needed with SQL Loader TNS error

Help needed with SQL Loader TNS error

Oracle 9.2.0.4; everything running (local) on a Windows 2000 sp4 machine

Scenario: SQL*Plus works just fine, as do import/export and various ASP
and perl programs

SQL Loader, however, fails with the error:

... sqlldr userid=3Did/pwd@(protected) control=3Dwmusitem.ctl data=3Ddata.txt

SQL*Loader: Release 9.2.0.4.0 - Production on Wed Sep 15 17:09:01 2004

SQL*Loader-704: Internal error: ulconnect: OCIServerAttach [0]
ORA-12541 (See ORA-12541.ora-code.com): TNS:no listener=20

I have stopped and restarted the listener, to no effect. (Yes, it really
is running. In fact, when I leave out @(protected) in the command, I get the
error that the listener cannot resolve the service name.)

Lsnrctl status also returns the same error:
lsnrctl status

Connecting to
(DESCRIPTION=3D(ADDRESS=3D(PROTOCOL=3DTCP)(HOST=3Dvc100)(PORT=3D1521)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
32-bit Windows Error: 61: Unknown error

I have checked sqlnet.ora and listener.ora and they appear to be correct
re: names, ports, etc.
Tnsping works.

People trying to connect to this db from other Windows machines also
experience intermittent problems.

Any ideas? Please ...


Thanks,
Leslie
