Question

I have a oracle database based on a server, and I want to import the data in the tables on the server.
I am trying to use sqlloadr(sqlldr) for inserting all data in the oracle database, which is on localhost and there is no problem in this case, but the problem occurs while I try to connect a web-server(not localhost).

The command that I’ve used in localhost case:

sqlldr <usrname>/<password> control=table.ctl log=table.log ERRORS=25000

and following is concerning to web-server

sqlldr <usrname>/<password>@LABSERVER control=table.ctl log=table.log ERRORS=25000

where I created a tnsnames.ora as following:

LABSERVER =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(Host = <hostaddress>)(Port = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = <servicename>)
    )
  )

but I got this error:

SQL*Loader-704: Internal error: ulconnect:OCIServerAttache [0]

ORA-12154: TNS:could not resolve the connect identifier specified

Any idea will be appreciated

“where I created a tnsnames.ora which
is like following:”

That seems to mean you have posted the TNSNAMES.ORA file from the database server.

Remember you also need a TNSNAMES.ORA file on the client. Is that correctly configured too?
