It can be different depends on used ODBC driver. For example: Driver={Microsoft ODBC for Oracle};Server=myServerAddress;

Odbc drivers are present, my web server communicates properly with the db and the query is running. I think you should create a documentation for verification of the requirements of function between the database and the web server. Do some 'troubleshooting is important. Have documentation that tells me the correct drivers to use operating system. Documentation that tells me if there are files to configure and more. All verifications that a user has to do to be able to use the form. This is not good

In the face of this your consideration "ODBC source was not registered and probably ODBC driver is installed Incorrectly" ... how to registered odbc on redhat/linux? .. and that odbc driver must be installed?

is there any user who has a problem like mine? ... Is there anyone who has tried to connect the module to a web server on a redhat6 oracle database? ... I'm the only user who encountered this problem?

Nobody has reported about similar issue. We know the customers use the extension connect to MS SQL and Access databases via ODBC and it works fine.

About Oracle, the extension doesn't support "OCI" PHP extension and we don't claim about native support of Oracle so we suggested to connect via ODBC as a possible solution. Sorry, but it is out of support configuration of DB and web servers as register of ODBC source, installing ODBC drivers on your servers and etc. In brief, it requires to install ODBC driver on DB server, register an ODBC source on server where your site is located, install ODBC PHP extension on web server and DB server should accept connections from web server.

Thank you for having responded to me. I try to explain all the operations, so maybe I can help you configure your module ari data table.
Odbc drivers are installed on both the web server where is my joomla site and also on the server which has the oracle db query. In fact if you send a query to the db from my webserver work properly, (as you can 'see from the attached. The problem is that the module can not connect. The question I want to do is: I have to configure something on hand server? ... I have to configure the odbc.ini file by hand? Do you think I have to configure something you do not know?
I want you to remember that use a server redhat6 ... I might have problems with this server?
