I download the trial version of oracle driver (Dbexpress) but I can't make the connection with my database, y write in the connection settings the user, password an database (192.1.0.106\database\WRXJDATA.DBF) but send me an error "TNS could not resolve the conect identifier specified "
could you tell me what is te problem?

Thanks, your friend Carlos...

You should assign the name of TNS alias (from tnsnames.ora file) to the Database parameter.

If you are using Oracle Direct driver, you should assign a value to the Database parameter in the format: Host:Port:SID

Hi,

I am currently trying the dbExpress driver.

First of all, I've been trying to open the connection using the string builder, but port does not look to be a member of [OracleConnectionStringBuilder] as it is described in the doc.

Then after, I tried connecting using the following connection string: but I always get the error: Cannot obtain Oracle client information from registry. Make sure that Oracle Client Software is installed, or use Direct mode of connecting to server.

As I don't want the Oracle client to be installed on the machine, I would like the Direct mode, which is specified I think; however, does not look to work...

Where am I wrong?

Thanks in advance[/code]

Maybe my question is a bit silly, but I did not succeed so far to connect the Oracle server.

So it would be nice to tell me how to solve the issue so I could continue my tests and check if I could suggest my Company to buy the driver...

Thanks in advance for your support.

For those experiencing the same problem in the future: dbExpress for Oracle does not look supporting Direct Access.

I have downloaded the trial version, which is the professional one, and suddenly there were no problem any more...
