ODBC and a remote Oracle database

Adam,

I installed the Oracle 9.2 Runtime, which includes client software. I'm using Oracle's driver, and am running on a Windows box.

  Hi!

  I'm hardly an expert at ODBC or the erlang interface, but maybe it could be that the local
  machine is lacking the odbc drivers? Or maybe the config files. Are you using some kind
  of Oracle-provided ODBC client library?

  Oracle also have their own OCI library -- Oracle Call Interface. I seem to remember that
  the "tnsnames.ora" file was involved in that interface.

  We use the "unixODBC-2.2.3-6" package on old RedHat 9 servers.
  It depends on config info in "/etc/odbc.ini" and "/etc/odbcinst.ini".
  They contain settings like server, port, database name, driver shareable object
  library etc.

  Hope that helps,
  /Adam Aquilon

    Hi all,

    I'm trying to access a remote Oracle database from Erlang through ODBC. I define the DSN pointing to a TNS Service Name which points to a remote Oracle database (and use Oracle's ODBC driver). Using the connection string "DSN=ev;UID=test;PWD=test" I get error
        {error,"No SQL-driver information available. Connection to database failed."}
    The same configuration works fine when ran in the machine where Oracle runs.

    Should a different connection string be used? Any other suggestions?
    Thanks,
        Sebastian-
